Privacy notice
Last updated 27 October 2026
The short version. We keep only what’s needed to run your revision hub. We never sell it, never show ads and never track you around the web. You can delete your account, and everything in it, from Settings whenever you like.
Who runs RevisionHub
RevisionHub is a small, independent project, currently in an invite-only beta. For anything about your data, email hello@revisionhub.cc.
Who it’s for
RevisionHub is for secondary school students, usually aged 14 to 16. You must be at least 13 to use it. If you’re under 16, please make sure a parent or carer knows you’re using it.
What we keep
- Your account: a username, your email address (for sign-in codes) and your password, which is stored scrambled so nobody can read it.
- Your revision: your subjects, exam boards, grades, weak topics, exams, timetable, time revised, test results, notes and any files or links you add.
- AI use: how many AI credits you’ve used and roughly what they cost, so your plan’s limits work.
- Payments (only if you subscribe): your plan, whether the subscription is active, its renewal and end dates, and Stripe’s reference numbers for you and your subscription. We never see or keep card numbers.
- Security: the IP address of each sign-in (in the emailed code and server logs), to spot and stop break-in attempts.
We don’t ask for your full name, school, address, date of birth or phone number. Please don’t put them in your username.
Why we keep it
To run the hub for you: to sign you in, save your work, plan your timetable, write and mark your tests, and keep the service safe. That’s the only reason (in UK data-protection terms, it’s needed to provide the service you asked for, and our legitimate interest in keeping it secure).
Who else sees it
- Anthropic, our AI provider, runs the AI. When you use an AI feature, the text, files or photos you send for that task, plus your board, tier, grades and topics, go to Anthropic to produce the answer. Anthropic doesn’t use this to train its models and keeps it only for a short time for safety checks.
- Stripe takes payments if you subscribe. The card details and email you give on Stripe’s payment page go straight to Stripe, which handles them under its own privacy policy (including fraud checks), and sends your receipts.
- Our hosting providers store the hub and send sign-in emails (The Email Shop for email and this website, and a private server for the app).
- Nobody else. We don’t use analytics, advertising or social-media trackers.
Anki, NotebookLM and exam-board websites are separate services you choose to open. What you do there is covered by their own privacy policies.
Cookies
One cookie, which keeps you signed in for up to 30 days. It isn’t used for anything else. The app also remembers small settings (like light or dark theme) in your browser.
How long we keep it
Until you delete your account. Deleting it removes your account, revision data and uploaded files from the server straight away. Copies in our backups are overwritten within a few weeks. Server logs, which include IP addresses, are rotated and old ones deleted as the server restarts.
Your rights
You can ask to see the data we hold about you, have it corrected, get a copy, or have it deleted. Most of this you can do yourself in the app. For anything else, email hello@revisionhub.cc and we’ll reply within a month. If you’re unhappy with how we’ve handled your data, you can complain to the Information Commissioner’s Office at ico.org.uk.
Changes
If this notice changes in a way that matters, we’ll tell you in the app before it applies.
