QSI Back to chat

Privacy Policy

Last updated: 15 October 2026 (QSI now finishes a careful answer (one that needs exact working, such as a calculation, a count, a proof or code written to a specification) on our server after replying to your browser, and keeps it in a private file for a short time, until your browser collects it: what the file holds and when it is deleted (see “Chat & Swarm” in section 2 and “Careful answers waiting to be collected” in section 6); earlier: Agent mode can now search the web and read public web pages and start from a .zip (see “Agent mode” in section 2); QSI keeps a one-year record of the websites Agent mode reads; logged-in members can chat and talk with Companions, AI characters made by QSI, as QSI opens them to members: QSI asks for your consent before you first use them and keeps a record of each answer, what is sent where, the automatic safety check of short lines you write or say to a companion, when QSI asks whether you are 18 or older, what QSI keeps, child-safety reports, and the “Ask QSI to help me” requests; what is kept after you close your account (see “Your account” in section 6); a line on the third-party AI models that QSI’s features use (see section 3); QSI Pro members can try Agent mode, a preview for a limited time, where Alpha Core changes, runs and fixes the code in a chat by itself: what is sent where, the encrypted copy of a task that QSI’s server keeps while it runs, what your browser keeps and how to delete it, and that the AI processing partner for Agent mode works in Singapore (see “Agent mode” in section 2); the AI services QSI uses are now described together in section 3, instead of in separate rows, with what they receive and how long they may keep it; this doesn’t change how your data is processed or your rights in section 8; logged-in members can now add an optional profile (the name QSI calls you, a preferred language and, if you choose, your city), kept with your account on our server: what QSI keeps and what is sent with your messages; and, where QSI offers it, you can buy QSI Pro from outside India: what QSI keeps for your export invoice; logged-in members can now turn on Memory: short notes about you that QSI keeps only in your browser, locked to your login, and uses in later chats, Swarm and live voice; anyone can now use a Temporary chat, which isn’t saved and doesn’t use Memory; QSI now asks you to accept this policy again before a photo edit only when the way photo edits work has changed; you can now run code from an answer, which runs in your browser on your device and isn’t sent anywhere, and logged-in members can use Coder mode to build, fix and run code with Alpha Core: what is sent where and what QSI keeps; QSI Pro, an optional paid plan: payments go through Razorpay, our payment aggregator; what QSI keeps about your payments and for how long, and that QSI never stores your card, UPI or bank account details; if you agreed to an earlier version of this policy, QSI now asks you once to accept this version before your first photo edit, and records the version and the time; reports about pictures now get a report ID and are reviewed by our Grievance Officer, who is told about them by email; QSI now decides by itself when a question needs up-to-date information and searches the web, and there is no web-search setting any more; for logged-in members, chat answers may use an AI service’s own web search, and QSI keeps daily counts of those answers; with or without an account, live voice can now search the web, show text cards on screen, change its speaking speed and use the same recent chat context; you can now also attach Excel and PowerPoint files in chats; in live voice you can now share a PDF, Word, Excel, CSV or PowerPoint file, which your browser reads so that only its text is sent; logged-in members can now ask for pictures right in the chat and change a photo they add (“photo edits”): what is sent where, what QSI keeps, the 180-day record of picture requests and the labels on every picture, and QSI doesn’t edit photos that show children; you can download answers and voice documents as PDF, Word, PowerPoint or Excel files, which are made on your device; live voice runs through QSI’s voice relay on Cloudflare; run by Quantum Synthetic Intelligence Private Limited; AI service providers described without names) · Version 2.19

1. Who we are

QSI is a Synthetic Intelligence (SI) platform, made in India for the world, at quantumsi.in. It is run by Quantum Synthetic Intelligence Private Limited, Nagpur, Maharashtra, India (“we”, “us”). Under India’s Digital Personal Data Protection Act, 2023 (the “DPDP Act”), Quantum Synthetic Intelligence Private Limited is the Data Fiduciary: we decide why and how personal data is processed through QSI.

This policy explains what happens to your data when you use QSI. It is written with reference to the DPDP Act and the Digital Personal Data Protection Rules, 2025. It is meant to be read on its own; you shouldn’t need any other document to understand it.

2. What data we process and why

Accounts are optional: most features work without logging in. Logging in raises your daily limits and adds a few members-only features, such as making pictures. The table below lists each feature, the data involved, why we need it, and whether our server keeps it.

FeatureData involvedWhyKept by QSI’s server?
Chat & Swarm
  • Your message (up to 4,000 characters)
  • The last 8 turns of the conversation (up to 2,000 characters each)
  • Your settings: chosen agent, Chat or Swarm mode
  • In Swarm mode, the browser sends several steps (plan, run, review, combine) that include your message and the AI’s intermediate drafts
  • Attachments you add (optional): photos and images, resized in your browser and sent as JPEG (up to 4), and the text of documents (PDF, Word .docx, Excel .xlsx, PowerPoint .pptx, text and code files; up to 40,000 characters; for spreadsheets, also the column totals your browser calculated). The text is extracted in your browser; the original files are not uploaded. For a scanned PDF with no text, up to 3 page images are sent instead.
  • In Swarm mode, images go only to the planning step. The other steps get a short description of the attachments and document excerpts of up to 12,000 characters.
  • Requests with attachments are sent to QSI’s AI services, never to the backup providers.
  • Attachment contents are sent only with the message you attach them to. Later messages in the same chat include only the names of earlier attached files as part of the recent conversation.
To get an answer from an AI model and show it to you. No, except a careful answer waiting to be collected. The server passes the content to an AI provider and returns the answer. It does not save your messages, photos or document text. The exception is a “careful answer”: the answer to a question that needs exact working (for example a calculation, a count, a proof, totals from records you give, or code written to a specification), which QSI may work out with extra care for up to about 2 minutes. For such an answer, our server replies to your browser at once, finishes the answer afterwards and keeps the result in a private file outside the public web folder until your browser collects it (your browser asks for it every few seconds). The file holds that result: the answer (in Swarm, a careful draft, the review notes or the final answer) with any source links; for QSI’s second check of an answer, its verdict and, if it finds a mistake, the corrected answer and a short list of the mistakes found; or a short error message if the answer could not be finished. With it come technical details, such as which QSI agent answered, whether the web was searched, the kind of task (code, data or maths), whether the answer was cut short or will be checked again and how long it took, and, for a QSI Pro member whose Pro boost could not pay for a full-length Swarm answer, a note saying so and the date the boost refills. The file also holds the hash of your random account number or, if you are not logged in, your hashed IP address (so that no one else can collect it), which step it is for, whether it is finished, and when that step was started and finished. Your message, the conversation, attachments and Memory notes are not stored in it, though the answer itself may repeat details from them. The file is deleted as soon as your browser collects it, otherwise at the first automatic clean-up after about 10 minutes, counted from when QSI started working on it (clean-ups run whenever QSI’s chat or Swarm is used, so usually within a few minutes after that); see also “Careful answers waiting to be collected” in section 6. This also applies in a Temporary chat. While a large message with attachments is being received, our web server and its PHP software may briefly hold it in temporary files, which they delete when the request ends; QSI also deletes any PHP temporary file left behind (for example after a server fault) once it is more than 15 minutes old. (See section 6 for the error log.)
Voice input (microphone) Your voice recording (up to 1 minute), recorded only while the mic button is on, and your chosen voice-input language. To turn your speech into text in the message box. You can edit it before sending. No. Our server passes the recording to an AI speech-to-text service QSI uses and returns the text. The temporary upload file is deleted automatically when the request ends.
Live voice mode
  • Your voice, streamed from your browser through QSI’s voice relay to QSI’s AI services while voice mode is open, and QSI’s spoken replies streamed back
  • Instructions and settings for the conversation, prepared by our server: QSI’s speaking style, your chosen voice (Rads or Mayur), agent, voice-input language and live-voice speed, and, if you start voice mode inside an existing chat, the last messages of that chat (as text) so QSI knows the context: your browser sends up to the last 8 turns of up to 1,200 characters each, and our server uses all of them, with or without an account
  • A written transcript of both sides, produced by the AI service and shown on screen as captions (on by default; you can turn them off)
  • For everyone, with or without an account: web searches run by the AI service during the conversation, based on what you said, when you ask about something time-sensitive. The only location hint QSI gives the AI service is country India and time zone Asia/Kolkata.
  • For everyone, with or without an account: text cards shown on screen during voice (such as steps, lists, drafts and links), created by the AI and saved with the transcript in your browser only. Check links before opening them.
  • For everyone, with or without an account: document cards when you ask for a PDF, Word, PowerPoint or Excel file during voice. The AI service writes the document’s text and sends it through QSI’s voice relay to your browser, which shows download buttons; the file itself is made on your device. Document cards are saved with the transcript in your browser only.
  • For everyone, with or without an account: the text of files you share with the file button during voice (PDF, Word .docx, Excel .xlsx, CSV, PowerPoint .pptx or text files; up to 40,000 characters per file and 5 files per voice session). Your browser reads the file and sends only its text, with the file name and a short description such as the number of pages, sheets or slides, and for spreadsheets the column totals your browser calculated, through QSI’s voice relay to QSI’s AI services. The original file is not uploaded. Scanned PDFs and pictures can’t be shared in voice. Only the file’s name and a short description (such as the number of pages, sheets or rows) are saved with the transcript in your browser; like other chat messages, that line is sent as recent conversation if you continue the chat or start voice mode again in it.
To let you talk with QSI in real time, with natural replies you can interrupt, to answer time-sensitive questions with up-to-date information, to show things that are easier to read than hear, to make documents you ask for and to talk about files you share. To control cost, voice mode is limited to 3 minutes a day without an account, 15 minutes a day with a free account, and 8 hours a day for the whole site.

No audio, no transcripts, no web searches, no cards, no documents and no shared files. Our server only gives your browser a short-lived, single-use access code that only QSI’s voice relay can read; the audio never passes through our server, live-voice web searches are run by the AI service itself, cards and document text come from it through the relay to your browser, and the text of files you share goes from your browser through the relay to it. The recent chat text and settings listed above pass through our server to prepare the instructions, as with a normal chat message, and are not saved.

When voice mode ends, the transcript, any cards or documents shown on screen and the names (with a short description) of files you shared are saved as normal messages marked “Voice” in your browser’s chat history only. To enforce the daily limits, our server keeps usage counters: see “Rate limiting & security” below.

Camera The photo you take, only after you tap Take photo and your browser asks your permission. The live camera preview stays on your device. On some devices, your phone’s own camera app or photo picker opens instead, and only the photo you choose is used. To attach a photo to your message. No. The photo is handled like any other image attachment: resized in your browser and sent to QSI’s AI services with your message. It is not saved in your chat history.
Making pictures and photo edits (logged-in members only)
  • Your picture request (up to 1,000 characters), typed in the chat or in Picture mode. In the chat, your browser sends a message to QSI’s picture check only when it looks like a clear request for a picture, or for a change to a photo you added; if QSI’s safety check finds it isn’t one, it is answered as a normal chat message instead (see “Chat & Swarm” above), and QSI keeps only a note that a check was made (the time, whether it was about a picture or a photo, and the coded keys for your account), not your message or photo. If you ask for a change to your last picture, QSI makes a new picture from a combined description, so your browser also sends back the English description of that last picture.
  • The result of QSI’s safety check of your description against the picture rules in our Terms, and an English description of the picture that QSI writes from yours, with a one-line caption in your language (for screen readers)
  • The finished picture (a JPEG of about 1 megapixel: 1024 × 1024 pixels for a new picture, the shape of your photo for a photo edit), its label and its picture ID (see “Labels on pictures” below this table)
  • Your account, because only logged-in members can make pictures, and the usage counts described under “Rate limiting & security” below
  • Photo edits (for the logged-in members they are offered to): the photo you add (one at a time), which your browser first makes smaller (at most 1,536 pixels on its longest side) and saves as a new JPEG file, which leaves out the location (GPS), camera and other details stored in the original file; your description of the change; and your confirmation that you may edit the photo and that the people in it agreed. QSI doesn’t edit photos that show anyone who is, or may be, under 18.
  • Like other messages, your picture requests and their captions are saved in your chat history in your browser, and can be part of the recent conversation sent with your later chat messages.
To make the picture or photo edit you ask for; to refuse, before anything is made, pictures and edits that would break the law or our rules; to label every picture as AI-generated, as India’s IT Rules require; and to deal with complaints and lawful requests about pictures made with QSI. To control cost, each member can make up to 10 pictures a day, and QSI Pro members, with boost left, up to 20. A photo edit counts as one of them: free members can make 1 photo edit a day once photo edits are open to all members, and QSI Pro members up to 5 photo edits a day. QSI makes at most 300 pictures a day for everyone together, at most 100 of them photo edits, but QSI Pro members can go past these limits on their Pro boost.

QSI’s safety check has two steps: a word list on our server, then one of QSI’s AI services, which receives your request (and, for a photo edit, a copy of your photo at most 1,024 pixels on its longest side), checks it and writes the English description (it never goes to the backup services). A request the word list refuses is not sent on. Only the English description, the picture settings, a coded identifier for your account and, for a photo edit, your photo (at most 1,536 pixels on its longest side) go to the third-party AI picture provider (see section 3), which makes the picture. After QSI labels an edited photo, and before your browser can collect it, the same provider’s free safety check also checks it for sexual, violent and self-harm content.

Your photo (photo edits): not saved by QSI. QSI’s code never saves the photo you add. Our server checks it and has the edit made while holding it only in its working memory, for a few seconds up to about 2 minutes, and drops it as soon as the edit has been made. While the photo is being received, our web server and its PHP software may briefly hold it in temporary files, which they delete when the request ends; QSI also removes PHP’s copy as soon as the photo has been read, and deletes any PHP temporary file left behind (for example after a server fault) once it is more than 15 minutes old. Your browser keeps the photo you added with the chat, in its own storage on this device (IndexedDB, under qsi-v2-pictures), so you can compare it with the result or make the edit again, until you delete that chat or use Settings → “Clear all”.

The picture: only until your browser collects it. A picture takes from a few seconds to about 2 minutes. Meanwhile your browser checks back with our server, and the finished picture waits in a private file there. It is deleted as soon as your browser collects it; a picture that is never collected is deleted in an automatic clean-up once it is 1 hour old. After that QSI has no copy, so download the pictures you want to keep. Your browser keeps your pictures with the chat, in its own storage on this device (IndexedDB, under qsi-v2-pictures), until you delete that chat or use Settings → “Clear all”. It also remembers when it last showed you the picture rules (qsi.v2.picnotice).

A record of each picture request: yes, for 180 days. Unlike chats, our server keeps a record of every picture request, including refused ones, because India’s IT Rules require us to be able to trace AI-generated pictures and deal with complaints. Each record holds: the time; your description (and the earlier description, if you asked for a change); the result of the safety checks; the English description sent to the picture provider; the picture ID; a fingerprint (SHA-256 hash) of the finished picture and of the file the provider returned; technical details such as the picture’s size, how long it took and what it cost; and two coded keys for your account: a hash of your random account number and a keyed hash of your email address, so that a complaint can still be matched to an account after it is deleted. It also records whether you asked in the chat or in Picture mode, and any report you send us about a picture (a report ID, the picture’s ID, the reason you chose and your note). Our Grievance Officer reviews every report and is told about it by a short email (at busy times, several reports in one email) with the report ID, the picture’s ID, the reason, the time and the coded key for your account; that email never contains your note, the picture, its description or your email address. A message typed in the chat that QSI’s safety check finds isn’t a request for a picture or a photo edit is not kept: only a note that a check was made, with the time, whether it was about a picture or a photo, and the two coded keys. For a photo edit, the record also holds: a fingerprint (SHA-256 hash) of your photo as uploaded and as sent; a short visual fingerprint (a 64-bit “perceptual hash”) of your photo and of the edited picture, which helps match copies that were resized or re-saved but can’t be turned back into a picture; the photo’s size; your confirmation; the yes/no results of QSI’s check of the photo (how many people it shows, and whether anyone may be under 18 or a well-known person, is shown with nudity, or whether it shows a document or a news event; QSI does not identify anyone); the kind of change; and the result of the final check of the edited picture. It never holds the picture itself, your photo, your IP address or your email address in readable form. See section 6 for how long each part is kept.

Web search For logged-in members, chat answers and Swarm’s web-search step may use the AI service’s own built-in web search: the AI service decides whether to search and runs the searches itself, using words from your message and the recent conversation (the only location hint QSI gives it is that you are probably in India, never your city or exact location, unless you turn on Memory and it holds your city, or you turned on “Use my city for local answers” in your optional profile: then the AI service may use the city only when your question depends on where you are and you didn’t name a place). Otherwise, a search query based on your message is sent from our server to DuckDuckGo or Wikipedia; for weather in a known city, only the map coordinates of the city are sent to Open-Meteo, not your message. Live voice does not use DuckDuckGo, Wikipedia or Open-Meteo: it uses the AI service’s own web search (see “Live voice mode” above). To include up-to-date information and source links in the answer. QSI decides by itself when a question needs up-to-date information; it also searches when you ask it to, or when you use the Gamma Link agent. There is no setting to turn web search on or off. No. Results are shown to you as source links. When the AI service searches, it sends the searches it ran and the addresses of the pages it looked at back to our server with the answer; our server uses them only to show you the source links and does not keep or log them. To keep that search within daily limits and a monthly budget, our server counts how many answers used it (see “Rate limiting & security” below).
Running code (the Run button) When you tap Run on a code block (JavaScript, and Python where QSI offers it), the code runs in your browser, on your device, inside a separate, sandboxed part of QSI’s website that can’t see your QSI account or reach other websites. The code, anything you type in its Input box, and the output all stay in your browser. The first time you run Python, QSI asks before your browser downloads the free Python runtime (Pyodide: about 7 MB, plus about 9 MB the first time your code uses pandas) from jsDelivr (see below); your browser checks those files against fixed fingerprints and usually keeps them, and remembers that you agreed to the download (qsi.v2.pyok). So you can try code examples without installing anything. No. The code, your input and the output are not sent to QSI’s server, to any AI service, or to jsDelivr, and nothing your code makes is kept after you leave the page.
Coder mode (logged-in members) In Coder mode, your message, the recent conversation in that chat, the text of any files you attach and any pictures you attach are sent to QSI’s AI services to answer you. Before sending, your browser checks attached text for things that look like passwords or keys and offers to hide them. Agent mode, which you can turn on inside Coder mode where QSI offers it, works differently and has its own row below. If a paid plan later adds “pro coding answers” to Coder mode itself, those are answered by a specialist coding AI service provider, and this policy will say what is sent where before that is switched on. Your browser remembers whether it has shown you Coder mode’s 18+ note (qsi.v2.code18) and when it last suggested a plan (qsi.v2.codeUpsell). To write, fix and explain code with Alpha Core. No for the content: like other chats (apart from careful answers, see “Chat & Swarm” above), it is held in memory only while your request is answered and is not stored (Agent mode tasks are the exception: see the next row). QSI’s server keeps only counts: under a one-way code made from your account’s e-mail address with QSI’s secret key (it can’t be turned back into your address, and it stops the counts from starting again if an account is deleted and made again), how many code answers you used today, and how many of your Coder mode requests were refused or timed out today; under the hashed network address, how many members on your network used Coder mode today; and site-wide daily counts and a monthly cost total, which identify no one. For QSI Pro members, code answers beyond the free ones of the day use the Pro boost and are counted in its boost counter (see “QSI Pro (optional paid plan)” in this table). A random code for your account (not your email, and not reversible) is sent with the request to the AI service so it can spot misuse.
Agent mode (a preview for QSI Pro members, for a limited time, while QSI offers it)
  • In Coder mode you can turn on Agent and describe a task (up to 4,000 characters). Alpha Core then works on the files of that chat (the files in its code answers and text files you attached) by itself, in steps, until the task works or a limit is reached. Nothing is sent before you tap Start.
  • At the start, your browser sends the task, a list of the project’s files (names, sizes and line counts) and, if they fit (on the preview, up to 40 files and 40 KB together), the text of the files. Files whose names suggest passwords or keys (for example .env, key and credentials files) are never read or sent: only their names, sizes and line counts. If you carry on from an earlier task, that task’s summary and what was left go with it. Pictures are not used.
  • At each step, the AI asks for actions; your browser carries them out on your device and sends back the results: file lists and searches of the project, the text of the files the AI reads (up to 12,000 characters each), whether its changes worked, and what your code printed when it ran (up to about 4,000 characters per run), at most 16,000 characters per step. The code runs only in your browser, in the same sandbox as the Run button, with no internet access. (Alpha Core’s web search and web page reads, described next, are run by our server, not by your code or your browser.)
  • Before anything is sent, your browser replaces values that look like passwords or keys (in the task, the files and the results) with placeholders; the real values stay in your browser and are put back into the files you download. Our server checks again for such values. It can’t recognise every secret, so don’t put passwords, keys or other people’s personal data in a project.
  • Web search and web pages (in every Agent mode task, where this is available to your account; there is no box to tick for each task, and the start sheet says so before you press Start): the AI can ask our server to search the web or to read one public web page. For a search, the words the AI chose (they can come from your task and your files) are sent from our server to the AI service QSI uses for web search (see “Web search” in this section and section 3), which returns short summaries and the addresses of pages. For a page, our server fetches the address the AI chose, from our server’s internet address, not yours; it fetches only ordinary public web addresses (it refuses private, internal and numeric addresses and any address that was not in your task, a search result or a link on a page already read), follows the site’s robots.txt, and sends no cookies, no login and none of your data to the site. The site sees our server’s address and a request from “QSI-Agent”. Our server turns the page into plain text (about 12,000 characters at a time) and passes it, as text the AI must treat as information and not as instructions, to the AI processing partner that works on Agent mode tasks. A web page can contain text meant to trick the AI: QSI tells the AI to treat page text only as information, lists each page it read in the task and shows you the first words the AI was given from it. Because the web tools can be used in any Agent mode task, don’t put anything in a task that you wouldn’t want to leave QSI.
  • All of this goes through our server to the AI processing partner that works on Agent mode tasks (see section 3), with QSI’s instructions and a random code for your account (not your email, and not reversible) so the partner can spot misuse. As in Coder mode, QSI’s instructions include the name and preferred language from your optional profile, and your city and state only while “Use my city for local answers” is on. Your email address and your Memory notes are not sent.
  • In your browser: the task message and a plain-text summary of its result are saved in your chat history; Agent mode’s own data is saved in your browser’s storage on this device (IndexedDB, under qsi-agent): the project’s files, the task’s working copy and step list, the table of hidden values while the task is unfinished, and, after the task ends, the files it changed (with your real values put back) and its step list, so you can review, download or undo the changes. Your browser also remembers that you saw Agent mode’s first-use note (qsi.v2.agmIntro); starting a task that needs Python counts as agreeing to the Python download (qsi.v2.pyok, see “Running code” above).
  • You can start a task from a .zip of your project (up to 5 MB and 300 text files). Your browser opens the zip on your device; QSI doesn’t receive the zip. Binary and very large files, files with unsafe paths and files in folders such as .git and node_modules are not used by Agent mode, and the text files that are used are handled like any other project files. Your browser keeps a copy of the zip (in a storage of its own next to Agent mode’s, qsi-agent-zip), without files that hold keys or can run by themselves (such as .env or .git) and without node_modules, so you can download the finished project; it is removed with the chat (at the latest the next time Agent mode starts in your browser), by “Clear all”, or when you log out and remove QSI’s data from this device, and only the newest 10 are kept.
  • Agent mode isn’t available in a Temporary chat.
To change, run and fix the code of your project for the task you start, and to show you each step, every change and the result. To control cost, the preview gives each QSI Pro member up to 20 Agent mode preview answers per paid month (up to 5 in the first 7 days of a first paid month), up to 3 tasks a day, and at most 8 answers, 30 steps and 30 minutes per task; it pauses for everyone when its daily limit is reached. Web searches and page reads let Alpha Core check documentation and facts for a task.

An encrypted copy of the task, for a short time. While a task runs, our server keeps the conversation with the AI processing partner (your task, the file text that was sent, the AI’s replies and the results your browser sent back) in a private file outside the public web folder, encrypted (AES-256-GCM) with a key made for that task. Only your browser holds the key, which it sends with each step, so our server can read the copy only while it handles a step. QSI deletes the copy about an hour after the task ends (when it finishes, when you stop it or when it reaches a limit), and no later than about a day after the task started; these deletions run in QSI’s automatic clean-ups, while QSI is in use.

A task record, deleted with the copy: the task’s state, step and answer counts, times and costs, and short codes made from test results and error messages (never your files or your task text), linked to your account by the same one-way code as Coder mode’s counts. While you have an unfinished task, a pointer under that code says which task it is; an empty marker file named with that code stops two tabs from starting a task at the same time.

A record of the web pages Agent mode reads: yes, for one year. India’s rules require us to keep logs of how personal data is processed for at least one year, to be able to trace the use of our systems and to deal with abuse complaints, so our server records each web page request that Agent mode sends to a website (including one it then refuses, for example because the website’s robots.txt asks it not to read the page) in a private file outside the public web folder: the time, the one-way code for your account (as for Coder mode’s counts), the website’s name (not the rest of the address), the internet address of the website’s server, whether it worked, how many bytes came back and how long it took. An address that Agent mode refuses without sending anything (for example a private, internal or numeric address, or one that was not in your task, a search result or a page it read) is recorded by a short code for the reason only, without the address. Each web search is recorded too (the time, the one-way code, how long it took and what it cost), without the search words. QSI keeps no copy of a page’s text beyond the task: it sits in the task’s encrypted copy and is deleted with it. QSI also keeps each website’s robots.txt rules (not its pages) for about an hour so it doesn’t ask again.

Counts, like Coder mode’s: under that one-way code, how many Agent mode answers you used this paid month and today, how many tasks you started today, how many web searches and page reads you used this paid month and today, how many refused address requests you made today (to spot attempts to reach private addresses), and how many answers you used in the last hour (a task Alpha Core refuses also counts toward Coder mode’s daily refusal count); and site-wide counts of running tasks, of the preview’s spending today and this month, daily counts and a daily summary, which identify no one. See section 6 for how long each is kept.

Companions (logged-in members, 18+) Your messages and voice in companion chats and calls; which companion; daily usage counts; a “companions switched off”, “paused” or “blocked” record if that happens; reports and help requests you choose to send; a request for sexual content involving children, if one is made; the record of your Companions consent (each time you tap “I am 18 or older and I agree” or “Not now”, or switch Companions off); your answer if QSI asks “Are you 18 or older?”. To make companion replies, apply daily limits, keep companions safe, handle complaints, contact you when you ask for help, protect children, keep companions for adults, and record and prove your consent. No chat content, except the lines you choose to include in a report you send, and the lines kept in a child-safety report (see the next rows). Daily usage counts and a short record of each companion call: which companion, when and for how long (about 2 days), the switched-off, paused or blocked record (see section 6), counts of how often a helpline card was shown (numbers only), the time of the last refused request for sexual content involving children (on your account; see section 6), and reports you send, with the note you write, the lines you tick and your login email so we can reply (kept on our server for 180 days). Help requests and child-safety reports: see the next two rows. The record of your Companions consent: one line for each tap (“I am 18 or older and I agree”, “Not now”, or switching Companions off in Settings → Companions) with your account ID, the date and time, your choice, the version of the consent text (with a fingerprint of the exact text shown) and the version of this policy, kept permanently as proof of consent, also after you delete your account (see section 6); your current consent is also kept with your account until you switch Companions off or delete your account. Your answer to “Are you 18 or older?” (Yes or No), when you were asked and answered, and what kind of mention led to the question (for example school or board exams), and, once you have answered Yes, how many times that day the automatic safety check suggested that you may be under 18; kept with your account until you delete it.
Child-safety reports (Companions) Only if a member asks a companion for sexual content involving children: those lines and at most the two lines said just before them, the account ID and login email, which companion, whether it was a chat or a call, the date and time, the automatic decisions, and the IP address and browser of that request. Nothing else from the conversation. QSI keeps a request only when the automatic safety check also flagged it and companions were switched off for the account (or, when the check could not run, after a second such request within 24 hours). Never kept for someone who tells a companion about abuse, a worried parent, anyone asking how to keep a child safe or how to report abuse, or a member under 18. To protect children. A person at QSI reviews each report and decides whether to report it to Indian authorities (for example on cybercrime.gov.in or to the police); nothing is reported automatically, because an automatic decision can be wrong. Yes, privately (not on the website), until a person at QSI has reviewed it; if it is reported to the authorities, as long as they or the law require; otherwise deleted after the review (see section 6). It is kept even if the account is deleted. The person at QSI who reviews it gets a short email with the report number only, never the lines or the account details.
Help requests (“Ask QSI to help me”) Only if you tap “Ask QSI to help me” on a helpline or legal-help card and tick the box: what you need (a call back, help reporting to the police or a helpline, free legal aid, or something else), your phone number or email (your login email only if you tick “Use my login email”), the best time to contact you, your language, which companion’s card you used, when you asked, your account ID (so that only you can withdraw it), and the consent line you agreed to and its version. Never the conversation. So that someone from QSI can contact you about what you asked for. QSI contacts the police or a helpline for you only if you ask. It is never used for marketing and never shared with a companion or with Memory. Yes, privately (not on the website), until 90 days after the request is closed, or deleted at once if you withdraw it, ask us to or delete your QSI account (see section 6). You can withdraw it from the confirmation, in Settings → Companions, or by emailing hello@quantumsi.in with your request number. The person at QSI who handles it gets a short email with the request number and the time promised, never your contact details or what you need.
Chat history in your browser Your past chats (up to 50 chats, about 2 MB) in your browser’s local storage under qsi.v2.chats, and your settings (theme, read-aloud, voice, voice-input language, live-voice captions and speed, sidebar) under qsi.v2.settings. Your browser also remembers when QSI last suggested adding it to your home screen, and whether you added it (qsi.v2.a2hs), so the suggestion comes at most once a week and stops once QSI is added. Only the names of attached files are saved in your history, not the files, photos or their text. Temporary chats are not saved there, nor are your questions about what QSI remembers about you and their answers. Live voice conversations are saved there as text transcripts marked “Voice”, with any cards or documents shown on screen and the names of files you shared in voice (with a short description, never their text), never as audio. Agent mode keeps its project files in a separate store in your browser (see “Agent mode” above). So you can come back to your chats on the same device and browser. No. It stays on your device and is never uploaded as a whole. Only the current message and its recent context are sent with each request. Delete one chat, or all of them under Settings → “Clear all” (this also removes the Agent mode tasks of those chats from your browser). Clearing your browser data also removes it.
Memory (logged-in members who turn it on)
  • Your notes (at most 40, each up to 160 characters, plus an optional “About you” text of up to 300 characters): kept only in your browser’s local storage under qsi.v2.mem. followed by a code for your account, encrypted (AES-GCM) with a key our server gives your browser only while you are logged in. Your browser also keeps a list of chats waiting for a Memory update (qsi.v2.mem.pending. plus the same code: chat numbers only, never text), whether you marked this browser as a shared device (qsi.v2.mem.shared) and when you last chose “Not now” on the Memory offer (qsi.v2.mem.card).
  • To write or change notes: after some messages, or when you ask QSI to remember or forget something, your browser sends your recent messages in that chat (only yours: never QSI’s answers, the text of attachments or shared files, search results or picture requests; at most 3,000 characters) and your current notes through our server to QSI’s AI services, which suggest changes. Our server checks every suggestion against its own rules and signs the notes it allows, so only notes it checked can be sent back later. Every change is shown under the answer, with Undo. A note you type, edit or add from a file is checked and signed by our server the same way, without the AI service.
  • When you chat, use Swarm or start live voice: the notes that matter for your message (up to about 1,200 characters in a chat, 800 in Swarm and 600 in live voice, and up to 2,000 when you ask what QSI remembers) are sent with it to QSI’s AI services (never to the backup AI services), with QSI’s rules for using them. Live voice uses only notes about your name, languages, place, work, studies, interests and projects. Answers that used your notes are part of the chat and are sent with later messages in that chat, like any chat message.
  • On our server: a record that you turned Memory on or off, when, the version of this policy you agreed to, a key number that changes when you turn Memory off or delete all notes, and, if QSI turned Memory off because you said you are under 18, when that happened.
So QSI can use what you told it in earlier chats (what to call you, your city, languages, work or studies and how you like answers) and you don’t have to repeat it. Memory is off until you turn it on, and you can turn it off at any time. No, except the on/off record and daily usage counts. The notes stay in your browser; our server never stores them and doesn’t log your messages, notes or the suggested changes. To keep note-writing within daily limits and a monthly budget, our server counts how many updates each account and each network made today, and keeps site-wide daily counts and a monthly cost total, which identify no one.
Temporary chat (everyone) The same as Chat & Swarm (and live voice, if you use it there): your messages and the recent conversation of that chat are sent to answer you. A Temporary chat doesn’t send or change Memory notes, and Agent mode isn’t available in it. For a chat you don’t want kept, for example on a shared device. No, except a careful answer waiting to be collected. It isn’t saved in your browser’s chat history either, and it ends when you close it, start another chat or reload the page. Pictures you make in it are still recorded for 180 days (see “Making pictures” above), and a careful answer waits on our server for your browser to collect it, as in any chat (see “Chat & Swarm” above).
Downloaded files (PDF, Word, PowerPoint, Excel) The text of the answer or document you choose to download, and its title. To give you a copy you can keep, print or share.

No. Files are made on your device, in your browser, and saved straight to your device. They are not sent to QSI’s server or to anyone else. QSI adds no name, logo or tracking to them; the only file information it sets is the title.

If you tap Share, the file goes to the app you pick, under that app’s own policies. If you choose Print, your browser’s own print feature makes the PDF or prints it, and it may add its own header or footer (such as the page address and date) and put the browser’s name in the PDF’s properties.

Read aloud The answer text you choose to hear, or every new answer if auto-read is on. Markdown, links and code are removed first. Also sent: your chosen voice and the detected language. To read answers aloud in a natural voice.

With a QSI natural voice (Rads or Mayur), the text is sent to an AI text-to-speech service QSI uses. To save cost, the resulting audio is cached on our server for up to 24 hours, in a temporary file named by a code computed from the voice, language and text. It contains no IP address or other identifier, but it is a spoken copy of the answer, so it contains whatever the answer said.

If you choose Browser voice, or if the QSI voice is unavailable, your browser’s or operating system’s speech feature is used instead, and QSI’s server does not receive the text. Some browsers use online voices that send the text to the browser maker (for example Google or Microsoft) under its own policies.

Account and login (optional)
  • Your email address, checked either by Google or by a 6-digit code we email you
  • If you use Google: your Google account ID and the name on your Google account (never your Google password)
  • When your account was created, when you last logged in, and how you log in (Google, email code or both)
  • Your confirmation that you are 18 or older and agree to this Privacy Policy, with the policy version and the time; if you later accept an updated version (QSI asks before your first photo edit if you agreed to an earlier one), that version and the time instead
  • A login cookie (qsi_sid) with a random code, of which our server keeps only a one-way hash, with the times the login was created, last used and expires
  • While a login code is pending: a keyed hash of the code (never the code itself), its expiry time and the number of wrong tries; and, for 24 hours, the times codes were sent to that address and the times wrong codes were entered for it (so we can send at most 10 codes a day to one address and pause email login for an address after 15 wrong codes)
  • Usage counts for your account (see “Rate limiting & security” below)
To let you log in without a password, keep you logged in, give members higher daily limits, and prevent abuse. You log in only if you choose to, after ticking the 18+ and Privacy Policy box.

Yes, in private files on our server, outside the public web folder. Your chats are still not stored and are not linked to your account, apart from the record of each picture request (see “Making pictures and photo edits” above), Agent mode’s short-lived, encrypted task copy (see “Agent mode” above), a careful answer while it waits for your browser to collect it, kept with the hash of your random account number (see “Chat & Swarm” above), and a child-safety report from Companions (see “Child-safety reports (Companions)” above). Login-code emails are sent through our host’s mail server.

From these files our server also keeps a private member list (a spreadsheet file in the same private folder) so we can run and support QSI: each member’s email address, name, sign-up and last-login dates, login method, and today’s usage counts (chat messages, Swarm runs, messages with attachments, pictures and live-voice minutes). It never contains chats. It is updated when members sign up or log in and every few minutes while QSI is in use, and your row is removed when you delete your account.

Your account stays until you delete it (Settings → Account → Manage → Delete account) or ask us to. Your registration data is kept for 180 days after you close your account. See “Your account” in section 6 for what that record holds. Login sessions end 30 days after you last used QSI while logged in, or when you log out. Login codes expire after 10 minutes.

Your profile (optional, logged-in members)
  • The name you would like QSI to call you (2 to 40 letters)
  • Your preferred language, if you choose one
  • Your city and your state or union territory (or “Outside India”), if you give them, and whether you turned on “Use my city for local answers”
  • When you last saved it
To greet you by name and make answers more personal. Your name and preferred language are added to the instructions sent with your chat, Swarm, Coder mode, Agent mode and live-voice messages to QSI’s AI services (see section 3), so answers can use your name and, when it isn’t clear which language you want, your language. They are never sent to the backup AI services: QSI takes them out of any request it has to send there. In live voice, your preferred language is added only while Settings → “Language (voice input & live voice)” is on Auto-detect; a language you chose there is used instead. Your city and state are added only while “Use my city for local answers” is on, for questions such as weather or nearby places; while it is off, they are kept only so you can turn it on without typing them again, and are used for nothing else. A profile is never required: QSI works the same without one, and you add one only if you choose to.

Yes, in your account’s file on our server, outside the public web folder (unlike Memory notes, which stay in your browser). It is not in our member list and is never shown to anyone else. If a Memory note gives another name or language, QSI uses the name (and the language, if you chose one) in your profile.

You can change or delete it at any time in your account (Settings → Account → Manage → Your profile). Deleting your account deletes it too.

QSI Pro (optional paid plan)
  • Your QSI account, and the state or union territory you choose when you buy (and, only if you ask for a business invoice, the GSTIN and the business’s legal name and address you give), for your GST tax invoice
  • If you buy from outside India (only where QSI offers it): your country, and the name and billing address you give, which an export invoice must show, and when you confirmed that you are buying from outside India and that the billing address is outside India; no state or GSTIN
  • From Razorpay, our payment aggregator: the IDs of your subscription, payments, invoices, refunds and any chargebacks, their status, amounts and dates, and the months you have paid for, and, for a purchase from outside India, whether each payment was made with a card issued outside India (this decides the tax on its invoice)
  • The numbers of the GST tax invoices and credit notes we give your payments
  • How much of this month’s Pro boost you have used (a small counter)
  • Your card, UPI and bank account details are entered only in Razorpay’s payment window (or in your UPI app or bank), never on QSI’s own pages. QSI never stores them, and never receives your full card number, UPI PIN or net banking password (see section 3).
To sell and provide QSI Pro: take the monthly payment you authorised, switch Pro on and off, stop renewals when you cancel, handle refunds and payment problems, issue GST tax invoices and keep the accounts that tax law requires.

Yes, in private files on our server, outside the public web folder, linked to your account’s ID rather than your email address. We also keep a private list of our GST invoices and credit notes (number, date, state, GSTIN and business name if given, amounts; for a purchase from outside India, the country and the name you gave) for our accountant and tax returns.

Payment and invoice records are kept for about 8 years (GST law: 72 months from the due date of the annual return for the year of the payment), even if you delete your account. Deleting your account first stops auto-renew. The boost counter starts again each paid month.

Earlier waitlist (closed)
  • Email address
  • Source (which sign-up form you used)
  • IP address
  • Browser user agent (browser and device type)
  • Sign-up time and status
  • Consent record: that you agreed, the time you agreed, and the policy version you agreed to
The waitlist is closed: QSI no longer offers it, its sign-up form has been removed from the site and it accepts no new sign-ups. If you joined earlier (only by ticking the consent box), we keep your entry to tell you if the planned paid feature it was for opens, and as a record of your consent. Yes, in a private file on our server. When you joined, we also sent two emails: a notification to our own inbox (your email, source, time and IP address) and a confirmation to you. That feature is not available, and no payment was taken.
Rate limiting & security
  • Chat: a SHA-1 hash of your IP address (for IPv6, only the first 64 bits), plus the times of your recent requests and counts of your chat messages and Swarm runs per day. While QSI works on a careful answer for you (see “Chat & Swarm” above), the times of your browser’s checks for it are kept under the same hash or, if you are logged in, under the hash of your random account number (a 1-minute window). The hash is not salted, so it could be matched back to the IP address: this is not anonymous.
  • Waitlist (closed): your IP address itself (used as the file name) and the times of any sign-up attempts (maximum 5 per hour)
  • Voice and attachments: the same hashed IP address and request times, kept in separate temporary files (voice input: a 60-second window, plus a count of voice inputs per day; read-aloud: 60-second window, plus a count of read-aloud characters per day; attachments: 10-minute window, plus a count of messages with attachments per day), plus site-wide daily counters and a daily read-aloud character count that do not identify anyone.
  • Live voice: the same hashed IP address (as the file name; if you are logged in, a hash of your account number instead), with a random session number, the start time, when its temporary access code expires and the seconds of voice time reserved and used for each voice session today (starts are also limited to 6 per 10 minutes), plus a site-wide count of voice seconds used today and a list of open voice sessions. While your voice session is open, that site-wide list also links its session number to your hashed IP address and, if you are logged in, the hash of your account number, so the session can still be ended correctly if your IP address changes and one network can’t hold more than two voice sessions at a time; the link is dropped once the session has ended.
  • If you are logged in: the per-day counts (chat messages, Swarm runs, messages with attachments, voice input, read-aloud characters and live-voice seconds) are kept under a SHA-1 hash of your random account number instead of your IP address, so your higher limits follow your account. So that one network can’t create many accounts, members on the same IP address also share a ceiling of three times the member limits, kept under the hashed IP address, and at most 5 new accounts can be created from one IP address per day.
  • Login: the hashed IP address with the times of login-code requests (up to 10 per hour), code checks and Google logins (up to 20 per hour each), plus a site-wide count of login emails per day that does not identify anyone. Each time you open QSI, it asks our server whether you are logged in; the times of these login checks and of other login requests are also kept under the hashed IP address (up to 300 checks and 120 other login requests per 10 minutes).
  • Pictures (members only): under the hash of your random account number, how many pictures you have made today, how many picture requests have reached the second step of our safety check today, how many our word list refused today, and the times of your recent progress checks (1-minute windows); under the hashed IP address, how many pictures members on the same network have made today (one network can make at most five times the member limit) and the times of your recent picture requests (1-minute windows); and site-wide counts of pictures, picture requests and refused requests per day and a total of picture costs per month, which do not identify anyone. While a picture is being made, our server also keeps a short job record with the hash of your account number, the hashed IP address, the picture ID, the English description and the caption; it is deleted when your browser collects the picture, or otherwise in the automatic clean-up once it is 1 hour old. For photo edits (members offered them), also: how many photo edits you have made today; how many refused photo-edit requests counted against you today and in the current 30-day period (several in a day, or many in 30 days, pause photo edits); how many of your photo edits our checks stopped today after they were made (3 stop photo edits until the next day); while a photo edit is being started, an empty lock file named with the hash of your account number; and only when it applies, a note under the hash of your account number (and, when picture making is paused for review or turned off, also under a keyed hash of your email address) saying that photo edits are paused, or that picture making is paused or turned off, and until when. Site-wide counts of photo edits and photo checks per day do not identify anyone.
  • Web search (answers that use the AI service’s own web search): under the hash of your random account number, how many such answers you got today; under the hashed IP address, how many members on the same network got today (one network can get at most three times the member limit); and site-wide counts per day, a total of their estimated cost per month and a daily summary (answers, searches, cost and failures), which do not identify anyone.
  • Agent mode (members it is offered to): in a temporary file named with the one-way code for your account (see “Coder mode”), the times of your recent Agent mode requests (a 1-minute window, at most 30 requests a minute); each task also counts as one chat message of the day. Agent mode’s other counts are described in its row above.
  • A site-wide daily request count that does not identify anyone
To stop abuse and keep the free service running for everyone. Yes, in temporary files on the server. Old request times are ignored after 60 seconds (chat, read-aloud), 10 minutes (attachments, live-voice starts, login checks and requests) or one hour (voice input, waitlist, login attempts), and are removed when you next make a request. The per-person counts (chat messages, Swarm runs, messages with attachments and new accounts per day, read-aloud characters per hour, live-voice seconds per day) start again at each new hour or day (UTC). The files themselves stay until our host clears its temporary storage. Picture counts are kept in private files outside the public web folder and deleted about 2 days after the day they count (the 30-day photo-edit counts about a month after they were last used); the monthly picture cost total after about 13 months. Web search counts are also kept in private files outside the public web folder and deleted about 2 days after the day they count; the site-wide totals and summaries after about 13 months. A note that photo edits or picture making are paused or turned off is deleted by the automatic clean-up once the pause has ended, or when we clear it after a review.
Older contact and deletion-request forms
  • Contact form: name, email address, subject, message, IP address and time
  • Deletion-request form: email address, reason, feedback, IP address and time
To answer contact messages and deletion requests. These forms come from the previous version of the site. They are no longer linked from QSI, but they still work on our server and may hold records from before. Yes, in files on our server. Each submission is also emailed to hello@quantumsi.in. To have any such record deleted, email privacy@quantumsi.in.
Hosting / server logs Standard web server logs kept by our host, Hostinger: IP address, browser user agent and the page or file requested. QSI’s own error log records technical failures. To deliver the website and to find and fix problems. Hostinger’s logs are kept under Hostinger’s policies. QSI’s error log is described in section 6.
jsDelivr Your IP address and browser details, when your browser downloads open-source libraries from jsDelivr: marked and DOMPurify on every visit; pdf.js (with its font and character-map files) or mammoth, only when you attach a PDF or Word file, or share one in live voice; and the document-making libraries html2canvas, JSZip and PptxGenJS, only when you download an answer or a document as a PDF, Word, PowerPoint or Excel file; JSZip also when you attach an Excel or PowerPoint file in a chat or share one in live voice, or download code as a project (.zip); and Pyodide (Python for the Run button and Agent mode) with the numpy and pandas packages, only when you run Python code, or start an Agent mode task that does, and agree to the one-time download. No referrer is sent. Your documents and the files you download are not sent to jsDelivr. To display formatted answers safely, to read attached documents in your browser (in chats and in live voice), and to make downloadable files on your device. No. This goes directly from your browser to jsDelivr.
Browser permissions Your browser’s microphone and camera permission for quantumsi.in. Your browser asks before QSI can use the microphone or camera. Stored by your browser, not by us. You can revoke it at any time in your browser’s site settings.

Whatever you type, say or attach in a chat is processed. If your message or attachments contain personal data, about you or anyone else, that data goes to the AI provider along with the rest of the message. Please read section 10.

Labels on pictures

Every picture made with QSI, including an edited photo, is marked as AI-generated: a small “AI-generated” label is drawn into one corner of the picture itself, a small “AI-generated” badge is shown next to it on the page, and the file carries a hidden tag (metadata) saying that it is AI-generated (for an edited photo, that it was edited with AI from a photo), with its unique picture ID, the date it was made and “quantumsi.in” as the service. The file contains no name, email address, account number, IP address or description; the picture ID links it to QSI’s record of the request. India’s IT Rules require the label and the identifier, so please don’t remove them (see our Terms). The AI provider that makes the picture also puts its own invisible watermark into it, which QSI can’t remove; the provider’s tools may use it to show which provider made the picture.

3. Who we share it with

We use the service providers described below to run QSI. Each receives only what it needs for its part of the service and handles it under its own terms and privacy policy, which we don’t control. Where we mention what a provider says about retention or training, it comes from that provider’s published documents, checked in September and October 2026, except for the AI processing partner that works on Agent mode tasks, whose retention and training terms come from its written commitment to QSI (see “Agent mode” below).

AI services. QSI’s AI service is provided by Quantum Synthetic Intelligence Private Limited. To answer you, QSI uses AI processing partners: other companies, which this policy calls “QSI’s AI services”. They may be outside India and may keep your messages, voice and photos for up to 30 days, or longer only if the law or a safety review requires it.

QSI's features use third-party AI models. Synthetic content made with QSI must be labelled, may not be used unlawfully, and misuse can lead to account termination and reporting to authorities.

This covers everything section 2 says is sent to an AI service, including pictures: one of QSI’s AI services checks each picture request that passes QSI’s word list (and, for a photo edit, the photo), and a separate third-party AI picture provider makes the picture. The picture provider’s free safety check also receives short lines you write or say to a Companion (only those lines, as text, never your chats, voice or account details) to look for signs of crisis, self-harm or harm to children. The picture provider may keep the request (with your photo, for an edit) and the picture it makes for up to 30 days, or longer only if the law or a safety review requires it; it also scans the images it receives for child sexual abuse material and keeps any it flags for review. Apart from the backup model hosts described below, QSI’s AI services say they don’t train their models on what QSI sends without permission (the picture provider: unless the customer opts in, and QSI has not opted in); some may make de-identified or aggregated data from it.

Agent mode. Agent mode tasks go to one AI processing partner that works only on them: a company in Singapore that processes them in Singapore and may share them with its affiliates to provide its service. In its written commitment to QSI, it doesn’t use what QSI sends to train its models and deletes it within 30 days. It receives what the “Agent mode” row in section 2 lists (with your optional profile, as part of QSI’s instructions), never your email address or Memory notes. Web searches for Agent mode go to the same AI service QSI uses for web search in chats (see “Web search” in section 2); the text of web pages goes to the Agent partner. Agent mode tasks never go to the backup AI routing service described below.

If the AI service that answers a chat is unavailable, the chat may instead go through a backup AI routing service to other model hosts, which follow their own policies. The routing service says it doesn’t store chats by default (it keeps request details such as token counts) and doesn’t train on them, but some hosts may store inputs or use them to train their models, so every request QSI sends through the backup service tells it to use only hosts that don’t store your inputs or train on them, and a model with no such host is skipped. The backup service and its hosts never receive attachments, voice recordings, read-aloud text, Memory notes or your profile (but the chat they receive can include the written-out text of what you said by voice, and the names of files attached earlier or shared in live voice).

If you are signed in to Google in this browser, the button may use Google’s own cookies, so Google may also know which Google account you are using. If you choose “Continue with Google”, you sign in in Google’s own window and Google sends QSI a signed token with your Google account ID, your email address and whether it is verified, your name, a link to your profile picture and, for work or school accounts, the organisation’s domain. QSI uses the domain only to check that Google manages your email address (Google login works for Gmail and Google Workspace addresses), keeps only your Google account ID, email address and name, and discards the rest. Our server also downloads Google’s public signing keys, which contain no personal data, to check the token.

Google handles this under its own privacy policy. We never see your Google password. If you never open the login window, your browser does not contact Google for QSI.

Google Privacy Policy

Cloudflare (Cloudflare, Inc., USA): QSI’s voice relay for live voice Only in live voice mode: your voice and QSI’s spoken replies, the transcript, any on-screen cards, the text of documents you ask for and the text of files you share, the instructions for your voice session (for a member with a profile: the name, the preferred language, and the city and state only with “Use my city for local answers” on), and the single-use access code, all passing through in encrypted form, plus your IP address and browser details (as for any website connection).

The relay passes live-voice data between your browser and QSI’s AI services. It does not store the audio or the conversation, and we have turned its request logs off.

Cloudflare privacy policy

Razorpay (Razorpay Payments Private Limited, India): only if you buy QSI Pro When you buy QSI Pro: your QSI login email (filled into its payment window; you can change it there), the plan and its price, a random QSI reference for your subscription, and everything you type into its window, such as your mobile number and your card, UPI or bank account details. When the payment window opens, your browser loads Razorpay’s checkout script from checkout.razorpay.com, so Razorpay sees your IP address and browser details. If you never buy Pro, your browser does not contact Razorpay for QSI.

Razorpay is an RBI-authorised payment aggregator. It processes your payments, your UPI AutoPay, card or bank mandate (eMandate) and each renewal, and may email or message you about them, under its own privacy policy; it may set its own cookies in its payment window. For UPI AutoPay and cards, your UPI app or bank also sends you the notices RBI requires before and after each charge.

Razorpay’s answers and notifications to QSI’s server about your payments also include details such as your email address, mobile number and how you paid (for example your UPI ID, the last 4 digits of your card or your bank’s name). QSI doesn’t use or keep them: it keeps only the IDs, statuses, amounts and dates listed in section 2, and never receives your full card number, UPI PIN or net banking password.

Hostinger Everything that passes through our website and server, including voice recordings, photos and document text on their way to QSI’s AI services (but not live-voice audio, which goes from your browser through QSI’s voice relay), the waitlist file, your account and login files, the sealed registration records of closed accounts, the Companions consent records, picture request records and finished pictures waiting to be collected, photos you add for an edit while the edit is being made, Agent mode’s encrypted task copies, task records and counts, the login-code emails (your email address and the code), the older form files and the read-aloud audio cache, the reports and help requests you send about companions, the record of your Companions consent and your answer to “Are you 18 or older?”, and the emails our server sends (login codes, the short notices of picture and companion reports to our Grievance Officer, and the short notices of child-safety reports and help requests to the person at QSI who handles them, which never contain your messages or contact details). Hostinger also keeps standard access logs. It hosts the site and delivers it through its content delivery network. Its logs are kept under its own policies.
jsDelivr (Volentio JSD Limited, England and Wales) Your IP address and browser details when your browser loads script files (for PDF, Word, Excel or PowerPoint attachments and files you share in live voice, the document-reader libraries; when you download a file, the document-making libraries). It says it does not link this data to individual users and uses no cookies. Its own CDN partners can also see IP addresses. Privacy policy

Our code can also work with other AI providers that are not switched on and receive no data. If we add or change a provider, we will update this policy before it starts receiving your data.

If you click a source link in an answer, you go straight to that website, and its own privacy policy applies.

We may also disclose data if the law requires it, for example in response to a valid order from a court or government authority.

For Companions: a request to a companion for sexual content involving children, with the account details and the IP address and browser it came from, may be reported to Indian authorities (for example on cybercrime.gov.in or to the police), always after a person at QSI has reviewed it; nothing is reported automatically. A help request you send with “Ask QSI to help me” is passed to the police or a helpline only if you ask us to.

For pictures, India’s IT Rules also provide that, where the law allows, we may tell a person harmed by a picture made with QSI (or someone acting for them) which member made it, and that we report certain offences, for example to the police. We do this only after checking the request, and only with the records described in section 2.

4. Processing outside India

Several of our providers are based outside India, and your data may be processed in other countries. The companies that run QSI’s AI services, and the backup AI routing service, are US companies and may process chat content in the United States. The exception is Agent mode: the AI processing partner that works on Agent mode tasks is a company in Singapore that processes them in Singapore and may share them with its affiliates to provide its service. The model hosts the backup service uses may be in other countries. jsDelivr is based in England and Wales, and its CDN partners operate worldwide. So your chat messages are likely to be processed outside India. Voice recordings, read-aloud text, photos, document text and live-voice audio, transcripts and web searches are processed by QSI’s AI services and may be processed in the United States. Live-voice audio also passes through QSI’s voice relay on Cloudflare’s worldwide network. We use your chat content only to answer the messages you choose to send. Picture requests, and photos you add for an edit, are checked by one of QSI’s AI services, and pictures and photo edits are made by a third-party AI picture provider; both are US companies and may process them in the United States. If you log in with Google, Google may process your sign-in data in the United States and other countries. Code you run with the Run button, and the code Agent mode runs, is processed only on your device. Memory notes are kept only in your browser; the notes sent with a message, and the messages sent to write them, are processed by QSI’s AI services and may be processed in the United States.

5. What we do not do

6. How long data is kept

DataHow long
Chats on QSI’s serverNot stored, except picture requests (see “Picture request records” below), Agent mode tasks (see “Agent mode task copy” below), careful answers waiting for your browser to collect them (see “Careful answers waiting to be collected” below), child-safety reports from Companions (see “Child-safety reports” below) and the lines you include in a report you send about a companion (see “Companion reports” below). They are held in memory while your request is being answered (a large request may briefly sit in temporary files of our web server and its PHP software, which they delete when the request ends; QSI deletes any PHP temporary file left behind after a server fault once it is more than 15 minutes old).
Careful answers waiting to be collected (on QSI’s server)Each one is deleted as soon as your browser collects it, otherwise at the first automatic clean-up after about 10 minutes, counted from when QSI started working on it (clean-ups run whenever QSI’s chat or Swarm is used, so usually within a few minutes after that). An answer that is finished more than 10 minutes after QSI started working on it is not kept, and QSI keeps no copy once the file is deleted. What the file holds: see “Chat & Swarm” in section 2.
Voice recordings on QSI’s serverNot stored. The temporary upload file is deleted automatically at the end of the request.
Live voice on QSI’s serverAudio, transcripts, web searches, cards, document text and the text of files you share are never received or stored. The temporary access code is not saved or logged. For the usage counters, see “Rate-limiting data” below.
Photos and document text on QSI’s serverNot stored. They are held in memory while your request is being answered (a large upload may briefly sit in temporary files of our web server and its PHP software, which they delete when the request ends; QSI deletes any PHP temporary file left behind after a server fault once it is more than 15 minutes old). In your browser, they are kept in memory only, never saved to storage, until you remove them, delete the chat or reload or close the page (so that Retry can reuse them). Only file names are saved in your chat history. (Agent mode is different: it saves the text files of its project, including text files attached to the task’s message, in your browser and, while a task runs, in its encrypted copy on our server; see the Agent mode rows below.)
Agent mode task copy on QSI’s serverAbout an hour after the task ends, and no later than about a day after it started. The clean-ups that delete it run while QSI is in use. The task record is deleted with it.
Agent mode web page and web search records on QSI’s serverOne year after the day of the request, then deleted. The robots.txt rules it keeps for re-use are deleted after about an hour of use, and by a clean-up within a day.
Agent mode in your browserUntil you delete the chat the task belongs to, use Settings → “Clear all”, log out and choose to remove QSI’s data from this device, delete your account or clear your browser data. Of the tasks that have ended, the newest 60 are kept, and of the zips you added to start tasks, the newest 10; an unfinished task’s working copy and table of hidden values are removed after 2 days.
Agent mode countsAbout 2 days after the day they count (the preview’s count for your paid month: about 60 days; the last hour’s count: about a day). The web search and page read counts and the count of refused addresses: about 2 days after the day they count, the paid-month ones about 60 days. The pointer to an unfinished task goes when the task ends; the empty marker file about 2 days after you last started or continued a task. The site-wide daily summaries and monthly cost totals, which identify no one, about 13 months.
Downloaded filesNot received or stored by QSI. They are made in your browser and saved on your device, where you control them.
Read-aloud audio cacheUp to 24 hours. After that it is no longer used and is deleted during later automatic clean-ups. It contains no identifiers.
Pictures on QSI’s serverDeleted as soon as your browser collects the finished picture. A picture that is never collected is deleted in a later automatic clean-up once it is 1 hour old. QSI keeps no copy after that.
Photos you add for an editQSI’s server: not saved; held in working memory only while the photo is checked and the edit is made (our web server and its PHP software may briefly hold the upload in temporary files, which they delete when the request ends; QSI removes PHP’s copy as soon as the photo has been read, and deletes any PHP temporary file left behind once it is more than 15 minutes old). AI providers: as for other requests (up to 30 days for abuse monitoring, longer if flagged; see section 3). Your browser: until you delete the chat or use Settings → “Clear all”.
Pauses and blocks on picture makingPhoto edits paused after several refused requests: 7 days (30 days after many in 30 days). Picture making paused after a request involving the sexual abuse of children: 30 days, while we review it. Picture making turned off after a suspected child-safety incident: until we have reviewed it. Each note is deleted once it has ended (by the automatic clean-up) or when we clear it.
Pictures in your browserUntil you delete the chat they belong to, use Settings → “Clear all”, or clear your browser data. Pictures you download stay on your device until you delete them.
Picture request records180 days from each request, even if you delete your account in the meantime, then deleted during later automatic clean-ups. Records linked to a complaint or a legal order may be kept longer: for 180 days from when we act on it, or as long as a court or authority requires.
Web search usage countsAbout 2 days after the day they count. The site-wide daily summaries and monthly cost totals, which identify no one, about 13 months.
Coder mode usage countsAbout 2 days after the day they count (monthly pro coding answer counts, when a paid plan has them: about 40 days). The site-wide daily summaries and monthly cost totals, which identify no one, about 13 months.
Picture report emailsIn our Grievance Officer’s mailbox while the report is handled, and deleted at the latest when the report’s record is deleted (180 days from the report, or longer if it is linked to a complaint or a legal order). They pass through our host’s mail server under Hostinger’s policies. At busy times a report waits for the next email: until then QSI’s server keeps its report ID and reason in a short list, which is emptied when that email is sent.
Companion usage countsAbout 2 days; totals that identify no one, about 13 months.
Companions switched off or pausedUntil reviewed, or until you delete your account.
Companion reportsKept on our server for 180 days, then deleted unless the law requires us to keep them.
The time of the last refused request for sexual content involving children (on your account)Only the time, never the request. It is used to see whether a second such request follows within 24 hours. It stays on your account until a person at QSI clears it after a review, or until you delete your account.
Companions blocked because of a request for sexual content involving childrenAs long as the account exists. If a person at QSI reviews the child-safety report and finds it was a mistake, the block is removed at once (unless another report for the same account is still kept). Deleting the account deletes the block; the report itself is kept (see the next row).
Child-safety reports (a request to a companion for sexual content involving children)Until a person at QSI has reviewed it. If it is reported to the authorities, as long as they or the law require; otherwise deleted after the review. Kept even if the account is deleted.
Help requests (“Ask QSI to help me”)90 days after the request is closed, or deleted at once if you withdraw it, ask us to or delete your QSI account (withdraw it in Settings → Companions or by emailing hello@quantumsi.in with your request number).
Companions consent recordsKept permanently, also after you delete your account, as proof of your consent. Each record holds only your account ID, the date and time, your choice (“I am 18 or older and I agree”, “Not now”, or switching Companions off), the version of the consent text (with a fingerprint of the text shown) and the version of this policy (or, if saving your agreement failed, a note saying so). Your current consent is also kept with your account until you switch Companions off or delete your account.
Your answer to “Are you 18 or older?” (Companions)With your account, until you delete it.
Picture usage countsAbout 2 days after the day they count. The site-wide monthly picture cost total, which identifies no one, about 13 months.
Chat history in your browserUntil you delete it, or clear your browser data.
Memory notes in your browserUntil you delete them (one by one, or with “Delete all notes everywhere”), turn Memory off, log out and choose to remove them, delete your account or clear your browser data. Turning Memory off, deleting all notes or deleting your account changes or removes your key, so notes left in any browser can no longer be read. After you log out without removing them, they stay locked in that browser and can be read again only when you log in.
Memory on/off recordWith your account, until you delete it.
Memory usage countsAbout 2 days after the day they count. The site-wide daily summaries and monthly cost totals, which identify no one, about 13 months.
Temporary chatsNot saved in your browser; they end when you close them or reload the page. On QSI’s server, a careful answer is kept as in other chats (see “Careful answers waiting to be collected” above). At QSI’s AI services, as for other chats (see “Data at QSI’s AI services” below).
Your accountUntil you delete it (Settings → Account → Manage → Delete account) or ask us to. Deleting it removes your account record, its login sessions and any pending login code straight away, and your row in our private member list. Your registration data is kept for 180 days after you close your account. If you ask us to close your account (write to privacy@quantumsi.in from the email address of your account), QSI closes it the same way, so the same applies. That sealed record holds only your email address, when your account was created, how it was created (Google or an email code), your latest confirmation that you are 18 or older and agree to this policy (with its version and time), and when you closed the account. It is kept in a private file outside the public web folder, can’t be used to log in or for any QSI feature, is used only to answer a legal request, and is deleted in an automatic clean-up once the 180 days are over. We can’t erase it sooner, but you can ask us what it holds. If you sign up again with the same email address, you get a new account. Picture request records are not deleted with your account: each is kept for 180 days from the request (see “Picture request records” above). Nor are the records of your Companions consent and any child-safety report (see above).
Your profile (optional)Until you change or delete it, or delete your account.
Login sessions and the login cookie30 days after you last used QSI while logged in (each day of use extends it), or until you log out or delete your account.
Login codesA code works for 10 minutes and is cancelled after 5 wrong tries or once used. The times when codes were sent to an address and when wrong codes were entered for it are kept for 24 hours, then deleted during later automatic clean-ups.
Login-code emailsIn your mailbox until you delete them. They pass through our host’s mail server under Hostinger’s policies.
QSI Pro payment and invoice recordsAbout 8 years (GST law: 72 months from the due date of the annual return for the year of the payment), even if you delete your account. QSI’s record of each payment notification from Razorpay (IDs, statuses and times, and for a refund or chargeback its amount): about 30 days.
QSI Pro boost counterStarts again with each paid month; one small file per paying account. It is kept with the payment records.
Data at QSI’s AI servicesChats, Swarm and Coder mode requests, attachments, voice input, read-aloud text, Memory notes and note requests, and picture requests and photos you add for an edit (at the AI service that checks them, and at the picture provider, which may also keep the pictures it makes): up to 30 days, or longer only if the law or a safety review requires it (section 3). Agent mode tasks, at the AI processing partner that works on them: deleted within 30 days, under its written commitment to QSI. Live voice: under the AI service’s terms, as for its other requests. The backup AI routing service and its model hosts: under their own policies. Deleting a Memory note doesn’t recall copies already sent with a message.
QSI error logRecords only technical failures: which provider or model failed and the error message it returned. It does not record your messages, picture descriptions, photos or pictures, the answers, transcripts, read-aloud text, document text, images or recordings. It has no automatic deletion schedule; we clear it manually. It never records login codes, login tokens, cookies or email addresses (if a login email can’t be sent, it records only a short code computed from the address). For Agent mode it also records a line with numbers only when a task ends (steps, answers used, cost and how it ended) and a daily summary, with no account, task text or file text.
Rate-limiting dataOld request times are ignored after 60 seconds (chat, read-aloud), 10 minutes (attachments, live-voice starts, login checks and requests) or one hour (voice input, waitlist, login attempts), and removed when you next make a request. The per-person counts (chat messages, Swarm runs, messages with attachments and new accounts per day, read-aloud characters per hour, live-voice seconds per day) start again at each new hour or day (UTC). The temporary files, with your hashed IP address (chat, voice, attachments, live voice, login) or, if you are logged in, the hash of your account number, or your IP address (waitlist), and your last request times or counts, stay until our host clears its temporary storage. The site-wide counters, including the daily read-aloud character count, do not identify anyone; the site-wide live-voice list holds your hashed IP address (and, if you are logged in, the hash of your account number) only while your voice session is open.
Older contact and deletion-request recordsUntil we delete them, or until you ask us to. The same applies to the copies emailed to our inbox.
Earlier waitlist (closed)It accepts no new sign-ups. Existing entries are kept until you ask us to remove you, or until we no longer need them to tell you about the planned feature, whichever comes first. The same applies to the notification emails in our inbox.
Hostinger server logsUnder Hostinger’s policies. We have not configured these.
Search and CDN providersUnder their own policies (see section 3).

If the law requires us to keep certain data for longer, we will keep only what is required, for only as long as it is required.

7. How we protect data

The measures we actually use:

To be clear, the waitlist file, the account files, the sealed registration records of closed accounts, the Companions consent records and careful answers waiting to be collected are not encrypted on disk. They are protected by being inaccessible from the web and by our hosting account’s access controls. No system is completely secure. If a personal data breach affects you, we will tell you, and we will inform the Data Protection Board of India when the law requires it.

8. Your rights

The DPDP Act and Rules give you the rights below. The provisions on these rights, and the Board’s complaint process for them, are expected to take effect in May 2027. We already honour these requests now, as our own commitment. You can:

How to use your rights

Email privacy@quantumsi.in and tell us what you want. For account or waitlist requests, please write from the email address you used. That address is how we find your account or entry and confirm the request is yours. We may ask for more information if we need to confirm who you are.

We acknowledge every grievance within 24 hours and resolve it within 7 days, as section 12A of our Terms says. That is well inside the 90-day limit that the DPDP Rules will set once they take effect.

About chats: we don’t keep your chats (an Agent mode task’s copy only while the task runs and for about an hour after, encrypted with a key only your browser holds), so we can’t retrieve, show or delete them for you. Our server’s copy of a careful answer is deleted as soon as your browser collects it, otherwise at the first automatic clean-up after about 10 minutes, counted from when QSI started working on it (clean-ups run whenever QSI’s chat or Swarm is used, so usually within a few minutes after that). A child-safety report from Companions is the exception: it is kept as described under Child-safety reports in section 2, even if the account is deleted. You control your chat history in your browser: delete one chat, or all of them with Settings → “Clear all”; this also removes the Agent mode tasks of those chats from your browser. Copies held by AI providers are covered by their policies (see section 3).

About Memory: you can see, correct, download and erase all your Memory notes yourself in Settings → Memory; we can’t see them. Notes already sent to QSI’s AI services as part of a message are kept by them like other chats, for up to 30 days (see section 3). On request, we can tell you what the on/off record on our server holds.

About pictures: we don’t keep your pictures once your browser has collected them, or the photos you add for an edit, so we can’t send you a copy later. If you add a photo that shows other people, you share their personal data with QSI and its providers: only do so with their agreement, and never add photos that show anyone undressed. We keep the picture request records described in section 2 for 180 days because India’s IT Rules require it, so we can’t erase them sooner, even if you delete your account; you can still ask us what they hold about you. Complaints about a picture made with QSI, for example one that shows you, go to our Grievance Officer, Mr. Mukesh Padole, at grievance@quantumsi.in (see also our Terms), who acknowledges them within 24 hours and resolves them within 7 days. Reports you send with “Report this picture” go to the Grievance Officer too.

Complaining to the Data Protection Board

If you are not satisfied with how we handle your grievance, you can complain to the Data Protection Board of India once its complaint process for these rights takes effect; the Board will publish how to file a complaint on its official website. Under the DPDP Act, you will need to raise your grievance with us first.

Language

This policy is currently in English. If you would like it in another language listed in the Eighth Schedule to the Constitution of India, email privacy@quantumsi.in.

9. Children

QSI is not intended for anyone under 18. Under the DPDP Act, processing a child’s personal data requires verifiable consent from a parent or lawful guardian. QSI has no way to obtain or verify that consent. So if you are under 18, please do not use QSI. When you log in, you must confirm that you are 18 or older. We record that confirmation but cannot verify it. QSI does not ask your age anywhere else, except in Companions: before you first use them you confirm that you are 18 or older, and a companion chat may ask “Are you 18 or older?” (see below). The waitlist form (now closed) did not ask your age.

Companions are for adults. If you tell a companion you’re under 18, companions are switched off for your account. If something you say only suggests it (for example school or board exams), QSI first asks whether you are 18 or older; if you answer No, companions are switched off, and so they are if the automatic safety check again suggests that you are under 18 after you answered Yes. We keep only that fact, your answer and that day’s count of such suggestions, and use them only for Companions.

QSI does not make pictures of children, and does not edit photos that show anyone who is, or may be, under 18: QSI’s safety check (by one of QSI’s AI services) looks at each photo before anything is made and refuses such photos.

If you believe someone under 18 joined the waitlist or has created an account, email privacy@quantumsi.in and we will delete the entry or account. We do not track, monitor the behaviour of, or target advertising at anyone, including children.

Memory is only for logged-in members. If you tell QSI you are under 18, in a chat or in a note you type, QSI turns Memory off and deletes its notes, and records only when that happened. QSI is designed not to save a school class or standard in Memory.

10. AI answers and sensitive information

Answers are generated by AI and may be wrong, incomplete or out of date. Check important information before relying on it, especially for medical, legal, financial or safety matters.

Companions aren’t doctors or therapists. Please don’t rely on them for health, legal or money decisions.

Please don’t share sensitive personal data in chats, such as Aadhaar or PAN numbers, bank or card details, passwords, health information, or other people’s private details. Anything you type is sent to the AI services described above.

Memory is designed not to save ID numbers, passwords, PINs or OTPs, bank, card or UPI details, phone numbers, email or home addresses, and refuses them when it recognises them. It saves health, religion, caste, political, sexual, money or legal details only if you clearly ask it to and then confirm, and doesn’t save such details about other people.

This includes photos and documents: don’t attach or share images or files that show Aadhaar or PAN cards, bank statements, medical reports or other people’s private details, and don’t speak such details into the microphone.

11. Changes to this policy

We will update this policy when QSI or its providers change, or when the law changes. The date and version number at the top will show the latest update. If we make a significant change that affects account holders or people on the waitlist, such as a new use of your email address, we will email you. We will ask for fresh consent where the law requires it.

This is Version 2.19. When you log in, we record the version of this policy you agreed to. If the way photo edits work has changed since the version you agreed to (the last such change was in Version 2.11), QSI asks you to accept the current one before your next photo edit, and records that version and the time; chat, voice, Memory, Agent mode and new pictures don’t need it. When you turn on Memory, QSI records the version of this policy you agreed to with it. When you agree to Companions, QSI records the version of this policy with your consent. Waitlist entries record the version each person agreed to when joining.
