Privacy Policy
Last updated: October 24, 2026. This policy applies from the day SAI's website opens to the public.
The short version (the full policy below is what counts):
- SAI is in early access. Your conversations may be saved and reviewed by our team to make SAI better, including to evaluate and train SAI's own models. A private mode is coming; until then, don't share anything you want kept private.
- We never sell your personal information and never use your conversations for advertising.
- Payments are handled by Stripe. We never see or store your full card number.
- You can ask us for a copy of your information or to delete it at support@talktosai.com.

1. Who we are
SAI is operated by Universal Network Development LLC, doing business as U.N.D Industries ("UND," "we," "us," "our"), a limited liability company organized under the laws of the State of Florida, United States. We decide how the information described here is used. This policy covers SAI's website, web app, voice features and memberships. Our Terms of Service also apply.
2. What we collect
| Kind | What it is | Where it comes from |
|---|---|---|
| Account and sign-in | If you sign in with Google or Apple: the account ID they give us, and your name and email if you allow it. If you sign in with email: your email address. Which membership your account has, which purchase it came from, and a dated record of every time you agreed to our Terms of Service and this policy (each sign-in and sign-up), of the purchase confirmation you ticked before paying, and of your optional choices. | You, Google or Apple |
| Profile | The name SAI greets you by, your username, what you told us you want help with (optional), and your optional choices (news emails, early feature invitations, being contacted about feedback), which are off unless you turn them on. If you fill in Settings > Personalization (what SAI calls you, what to know about you, how to answer), that too, and it is given to the AI with your messages so it can answer that way. You can change all of it in Settings. | You |
| Friends | If you use Friends (members only): who is on your list, the requests you sent or received, and who you blocked; invite codes you make (we keep only a scrambled copy, never the code itself); and the status and optional mood line you choose. Whether you have SAI open right now is known only for a few minutes, in memory, and is never saved: we keep no "last seen" time. Your friends see your username, name, status and mood; people with a pending request or who are blocked do not see your status, and "Appear offline" shows you as offline to everyone. | You |
| Conversations | What you type or say to SAI and what SAI replies. During early access these may be saved and reviewed (see Section 3). If you send a message to another company's model, part of it is sent as Section 4 describes. | You |
| Voice | If you use voice: the audio of what you say is sent to be turned into text, and SAI's reply text is turned into speech. We do not keep the audio. On a device that can, SAI's natural voice is made on the device itself: the reply text never leaves it, and the voice files it downloads once stay in your browser until you delete them (Settings > Data and privacy). | You |
| Membership and payment | Your email, the plan you chose, the amount, dates, and the payment status. The name and billing address you give Stripe are kept by Stripe. We never receive your full card number. | You and Stripe |
| Usage and safety | How much you used in your current 5-hour session and 7-day week (messages, voice replies and recordings turned into text, and their estimated cost), your share of SAI's capacity today, and a record when a message is blocked by our safety checks (the category). | Created as you use SAI |
| Technical | Your IP address and the requests your browser makes, which Cloudflare handles to deliver and protect SAI. For sign-in protection we keep only a scrambled version of your IP address, for at most one day. | Your device |
| Messages to us | Anything you send to our support or other email addresses. | You |
Please do not put passwords, card numbers, government ID numbers, health details or other sensitive information into SAI.
3. How we use it
- To run SAI: sign you in, activate your membership, answer your messages, speak and hear in voice mode, keep your usage limits, keep long conversations going by compressing their older part into short notes, and give each new chat a short name from its first message.
- To keep SAI safe: check messages and replies automatically for harmful content, prevent abuse and fraud, protect sign-in, and enforce our Terms.
- To make SAI better (early access): our team may read saved conversations and use them to find mistakes, improve answers, and evaluate and train SAI's own models. We do not let other companies train their models on your conversations.
- To handle memberships: take payment through Stripe, add the membership to your account, email you receipts, and answer billing questions.
- To talk with you: send messages you need about your account, membership, safety, and changes to our terms or this policy. We will not send you marketing emails unless you choose to receive them. If you join the free-tier waitlist, we keep that choice with your account and email you once when free access opens.
- To follow the law: meet legal, tax and accounting duties, respond to lawful requests, and protect our rights and the safety of others.
We never sell your personal information, and we do not share it for targeted advertising.
4. Who helps us run SAI
We share information only with companies that help us run SAI, only as needed for what they do for us, and under their own privacy terms:
- Cloudflare: hosting, security, and the AI models that power SAI's replies, safety checks, hearing and voice. Your messages and audio are processed on Cloudflare's network to produce replies; some voice models are provided to Cloudflare by its partners.
- Supabase: our database. Your account, your membership, your saved conversations and the other records this policy describes are stored with Supabase, in the United States (North Virginia).
- Stripe: payments. Stripe collects and keeps your payment details.
- Resend: sends our emails, such as sign-in codes and receipts.
- Google and Apple: only if you choose to sign in with them. Google also serves the fonts our pages use, so your browser asks Google for those files.
- Anthropic (Claude models) and Google (Gemini models): only for a message you send to one of their models, either because you chose it in the model menu or because you turned on Auto and Auto chose it. Before anything is sent, SAI keeps its own instructions, your Personalization, SAI's notes on your conversation and your profile on our side, and replaces details such as your name, email addresses, phone numbers, card and ID numbers, street addresses and links with placeholders. What is sent is your newest message and a few messages before it, with those details replaced. The answer comes back to us, the details are put back, and SAI writes the reply you see. Replacing details removes identifiers; it cannot make every message anonymous, because what a message is about can still identify a person. Auto never sends a message about your health, money, relationships, legal matters or identity, or one that contains such details; you can still choose a model yourself. Under their terms for businesses, Anthropic does not train its models on what we send, and we use Google's models only on Google's paid service, under which Google does not use what we send to improve its products. Each keeps what we send for a limited time under its own terms (Anthropic: generally 30 days).
We may also share information when the law requires it, to protect people's safety, to protect our rights, or as part of a merger, acquisition or sale of our business (the new owner would have to respect this policy). We will update this policy before we add a new kind of service that receives your personal information.
5. On your device (cookies and storage)
SAI stores a few things in your browser so it works, and nothing for advertising or cross-site tracking:
- your sign-in token, so you stay signed in;
- your settings: theme, chosen voice and microphone, whether SAI speaks replies aloud, and the mode and model you picked in the message box;
- your answer to our cookie notice;
- your chats (their messages, SAI's notes on them, their names, pins and projects), locked with a key that only your signed-in account can open, so another person using this browser cannot read them after you sign out. They stay until you delete them, or until your plan's chat storage is full, when the oldest chats that are not pinned are removed from the device first and SAI tells you;
- SAI's short notes or recap from your last conversation, for up to 30 days, so you can pick up where you left off. "New chat", "Start fresh" or signing out removes them;
- for a short time, the ids of chats you deleted whose saved copy SAI could not delete yet (for example while offline), so it can finish deleting them;
- for a moment, the first message you typed before signing in and the hand-off from Google or Apple sign-in.
Cloudflare may set strictly necessary security cookies to protect SAI from attacks. We do not use advertising or analytics cookies. Signing out removes what SAI stored in your browser except your locked chats, which stay unreadable until you sign in again; clearing this site's data in your browser removes everything, including your chats.
6. Do Not Track and tracking by others
SAI does not track you across other websites, so it treats every visitor the same whether or not your browser sends a "Do Not Track" signal. We do not allow advertising networks or other third parties to collect information about your activity on SAI over time and across websites. Google receives the standard technical details of your browser's requests when it loads our fonts or its sign-in button, and Apple does the same for its sign-in button.
No calls or texts, and no voiceprints. SAI contacts you only by email. We never call you or send you text messages. When you talk to SAI, your voice is turned into text to answer you and the audio is not kept; we do not create a voiceprint or use your voice to identify you.
7. How long we keep it
- Saved conversations: up to 12 months, then deleted or changed so they no longer identify you.
- Account and membership: while your account is active, then for as long as tax, accounting and legal duties require.
- Payment records: as long as tax and accounting law requires. Stripe keeps its own records under its policy.
- Friends: your list, requests and blocks until you remove them or delete your account; invite codes until they are used or expire (7 days), and their record until you delete your account; your status and mood until you change them or delete your account. Whether you are online is never stored.
- Usage counts: for each session (5 hours) and each week (7 days), deleted within about a day after that period ends; today's counts for everyone together, deleted after each day (UTC).
- Sign-in protection records: deleted after each day (UTC).
- Safety records of messages our safety checks blocked, and of messages whose reply was blocked: up to 12 months, to find repeated abuse and to meet the law. Deleting a chat does not delete them.
- Your agreements: a record of each version of these terms and of the Terms of Service you agreed to, and when, is kept for as long as your account exists and afterwards for as long as the law allows us to keep proof of what was agreed. Every earlier version of these documents stays published on our legal page.
- Backups: every night we copy SAI's database to private, encrypted storage so nothing is lost if something fails. Each copy is kept for 14 days and used only to restore SAI. Anything you delete leaves the backups within 14 days.
We may keep information longer when the law requires it or to resolve a dispute.
8. Security and breaches
We protect your information with encryption in transit (HTTPS), signed sign-in sessions, scrambled IP addresses, strict security settings on every page, and access limited to the people who need it. No system is perfectly secure, and we cannot promise that your information will never be accessed without permission. If a breach affects your personal information, we will tell you without unreasonable delay and within the time the law requires (for Florida residents, no later than 30 days).
9. Your choices and rights
- Access, correct, delete, or get a copy of your information: email support@talktosai.com with the subject "Data request" from the email on your account (or tell us how you sign in). We may need to confirm it is you, and we will respond within the time the law where you live requires.
- Delete your saved conversations: delete a chat in SAI (or every chat, in Settings > Data and privacy) and we delete our saved copy of it too, except safety records (section 7). You can also ask us at the same address. Archiving a chat only hides it on your device; it deletes nothing.
- Stop using SAI at any time, and turn off renewal or cancel a membership online in SAI under Settings > Plan and billing (or by emailing billing@talktosai.com).
- Depending on where you live, including California and other US states, you may have more rights, such as knowing what we collect and not being treated differently for using your rights. We honor them as the law requires. We do not sell personal information or share it for targeted advertising, so there is nothing to opt out of there.
Some information we must keep for legal, tax, safety or fraud-prevention reasons, even if you ask us to delete it.
10. Safety and the law
Every message and reply is checked automatically by safety models. When someone tells SAI they are thinking about hurting themselves, SAI points them to the 988 Suicide & Crisis Lifeline. A message that appears to involve the sexual exploitation of a child is refused, the account is paused at once, and our team is alerted. We respond to valid legal requests from authorities.
11. Children
SAI is only for people 18 and older and is not directed to children. We do not knowingly collect information from anyone under 18. If you believe a minor has used SAI, tell us at support@talktosai.com and we will delete their information.
12. Where your data is processed
We are in the United States. The companies that help us run SAI may process information in the United States and other countries, which may have different data protection laws from yours. By using SAI you understand your information will be processed there.
13. Changes to this policy
We may update this policy. We will change the "Last updated" date, and for important changes, including any new use of your conversations, we will tell you in SAI or by email before the change applies to information we already have.
