MatrixX Privacy Policy

Effective date: September 27, 2026 (updated October 5, 2026: update checks, contact form; October 8, 2026: website visit counts; October 9, 2026: signing in with Google, Apple, Microsoft or GitHub, and the web trial; October 15, 2026: reporting AI answers; October 17, 2026: voice replies, Telegram while your computer is off; October 21, 2026: paying with crypto)

MatrixX ("we", "us") makes the MatrixX app and runs MatrixX Cloud. This policy explains what data MatrixX and MatrixX Cloud handle, why, and your choices. Contact: martixx.support@gmail.com.

1. What stays on your PC

MatrixX runs on your computer. Your chats, files, memories, saved skills, logs and settings are stored on your PC (in your user folder) and are not sent to us. Speech recognition for voice commands runs on your PC.

2. What goes to MatrixX Cloud (only if you use it)

Account: your email address and a securely hashed password (we never see or store the password itself). If you sign in with Google, Apple, Microsoft or GitHub instead, that service tells us your verified email address and we keep only that; we don't get your password there or access to anything else in that account.
Subscription: your plan, its status and renewal date. Payments are processed by our payment provider; we don't receive or store your card details. If you pay with crypto, we keep the network, coin, amount and transaction ID of your payment. Blockchain payments are public by nature: anyone can see the sending and receiving addresses and the amount on the blockchain, which we don't control.
Credit usage: for each AI request or hosted tool: the time, which model or tool, and its cost, so we can deduct credits and show your credit history.
Your requests: when MatrixX uses MatrixX Cloud, the text, pictures or files in that request pass through our server to the AI provider that answers it, and the answer comes back to you. Our server doesn't store the content of your requests or answers; it keeps only the usage record above.
Voice replies: when MatrixX answers you with a voice message (for example on Telegram) and your computer has no voice key of its own, the text of that answer goes through our server to Google, which turns it into speech. We don't keep the text or the audio; we only count how many voice replies each account gets per day.
Telegram while your computer is off: while this is on (it is unless you turn it off on the app's Telegram page), we keep your Telegram bot's token (encrypted) and the Telegram user IDs you approved, so MatrixX Cloud can answer your bot while your computer is off or MatrixX is closed. Messages sent to your bot then go through our server to the AI model that answers them; voice messages go to Google to be written down, and spoken answers are made by Google too. We don't keep the audio. The last few messages of each chat are kept in the server's memory only (not saved), so answers can follow the conversation; they're gone when you send /new or the server restarts. Turning it off (or switching Telegram off) deletes the token and the IDs.

Update checks: when the app starts, it asks MatrixX Cloud whether a newer version is out. To count how many computers use MatrixX each day, we keep a scrambled one-way code made from your connection's address and the date (never the address itself) for 90 days.

Website visits: to count how many people visit our website each day and where they came from (for example a search engine or Product Hunt), we keep a scrambled one-way code made from your connection's address and the date (never the address itself) for 90 days, plus the name of the website that linked to us. We don't use advertising or tracking cookies.

Web trial: if you sign in on our website to use the free web trial, your browser keeps a sign-in cookie so you stay signed in (for up to 30 days, or until you sign out). It's used only for that. What you type in the trial is sent to a free AI model to answer it and isn't stored by us; we count how many trial messages you send each day.

Contact form: if you write to us through the website, we keep your email address and message so we can answer you.

Reported AI answers: if you press Report under an answer (or send /report on Telegram), the app sends us that answer, the request it was answering, the reason you picked and your note, so we can review it and improve MatrixX. Nothing else from your chats is sent, and nothing is sent unless you report it.

Waitlists: if you join a waitlist on our website (for example for the Mac version), we keep your email address only to tell you when that version is ready. Ask us to remove it at any time.

3. Who we share data with

Only what's needed to provide the service, with:

AI model, image, video and web-search providers that process your requests;
our payment provider, for subscriptions;
our hosting provider, which runs MatrixX Cloud;
authorities, if the law requires it.

We don't sell your personal data.

4. Why we use your data

To provide MatrixX Cloud and your plan, handle payments and credits, keep the service secure, prevent abuse, and answer your support requests. Where the law asks for a legal basis (for example in the EU or UK), ours are performing our contract with you and our legitimate interest in keeping the service secure.

5. How long we keep it

Account and subscription data: while your account is open, and afterwards as long as tax and accounting laws require. Credit usage records: 24 months. You can ask us to delete your account at any time.

6. Your rights

You can ask to access, correct, export or delete your data, or object to how we use it, by emailing martixx.support@gmail.com. Depending on where you live (for example the UAE, the EU or the UK), you may also be able to complain to your data protection authority.

7. Security

Passwords and sign-in tokens are stored as one-way hashes, connections are encrypted, and each account's access is limited to its own data. API keys you add to the app stay in a file on your PC and are never written to logs.

8. Children

MatrixX isn't meant for children under 16. If you think a child gave us personal data, contact us and we'll delete it.

9. Changes

We'll post changes to this policy here and tell you in the app or by email about important ones.
