Privacy policy

Last updated 12 November 2026

We collect as little as we can to run 84GPT. We don't sell your information, don't show ads and don't use tracking or analytics cookies.

What we keep

• Your account: the name, email address and profile picture from the Google, Apple or Microsoft account you sign in with.
• Your dongles: a scrambled fingerprint of each dongle's secret key (never the key itself), its name and when it was last online.
• Usage counts: how many AI questions, videos and messages you used each month, to apply the limits.
• Orders: what you bought, the amount, your name, email and shipping address, from Stripe.
• Messages: what you post in a Messages room, kept until the room expires after a week.
• Emails you send us: through the contact form or the "notify me" list, and for the list, which site you came from (like TikTok or Google).
• Website visit counts: how many times each page of this website was opened each day, and which site visitors came from. To count each visitor once a day without cookies, we keep a scrambled code made from the day, your connection and your browser, which can't be turned back into who you are and is deleted after 90 days. We don't keep IP addresses.

What we don't keep

• Your card details. Stripe handles payments, and we never see the card number.
• Your AI questions and answers. They pass through our server to the AI provider and aren't stored by us.
• Your WiFi password. It stays on the dongle.
• What you search or which pages you open on the calculator.

Who else handles it

• Cloudflare runs our server and database.
• Anthropic answers AI Chat and Math questions. They receive the question text, not your account details.
• Stripe takes payments and sends receipts.
• Google, Apple or Microsoft, whichever you choose, confirm who you are when you sign in.
• YouTube, Instagram and TikTok provide the content you look up in those apps.

Cookies

We use one cookie to keep you signed in, and a short-lived one during sign-in. Nothing else.

Children

Accounts are for people 13 and over. A dongle works without an account at small monthly limits, and in that case we don't know who's using it. If you think a child under 13 has made an account, tell us and we'll delete it.

Your choices

• See it: your account page shows your dongles, usage and orders.
• Delete it: Delete account on your account page removes your account, sign-ins and usage straight away. We keep order records as long as the law requires for tax and warranty.
• Anything else: contact us to get a copy of your data, correct it or ask a question. We reply within 30 days.

Changes

We'll post changes here and update the date at the top. If a change affects how we use information we already have, we'll email account holders first.
