Privacy policy

Revisia is run by Placeholder: [COMPANY NAME] (company number Placeholder: [COMPANY NUMBER]), Placeholder: [REGISTERED ADDRESS]. We decide how your data is used, which makes us the “controller” under UK data protection law. Our ICO registration number is Placeholder: [ICO REGISTRATION NUMBER].

Questions about your data: Placeholder: [privacy@revisia.example].

Your account

• Your first name, so Revisia can use it when you talk.
• Your email address.
• Your password, stored scrambled (hashed) so nobody can read it. If you sign in with Google, we get your name and email from Google instead, and no password.

Payment

Your card is handled by our payment provider, Creem. We never see or store your full card number. We keep a record of your plan, your payments, the last four digits of your card and your postcode.

What you study with

• Notes, slides, syllabuses and other files you upload.
• What you type in chat, and the text of what’s said in voice sessions.
• What Revisia creates for you: flashcards, practice questions, session summaries and your progress across topics.

Your voice

When you talk or record a lecture, your speech is sent to Groq and turned into text as you go, and Revisia’s replies are sent to OpenAI to be read aloud. Revisia never stores the audio.

Technical information

Basic information our servers need to run and stay secure, such as your IP address, browser type and when you logged in. We keep these logs for Placeholder: [RETENTION PERIOD].

We don’t use your notes or conversations to improve or train AI, and we don’t build advertising profiles. We will never send you marketing emails without asking first.

To answer you, Revisia sends the relevant parts of your notes and conversation to Anthropic. We only use providers whose contracts say they won’t train on your data and won’t keep it beyond what’s needed to answer.

We use a small number of companies to run Revisia. They act only on our instructions, under contracts that protect your data:

• Vercel and Supabase: stores the app and your data.
• Anthropic: generates Revisia’s answers (see above).
• Groq: turns your speech into text, for voice sessions and lectures.
• OpenAI: reads Revisia’s replies aloud in voice sessions.
• Creem: takes payments.
• Placeholder: [EMAIL PROVIDER]: sends receipts, trial reminders and account emails.
• Google: only if you choose to sign in with Google.

We never sell your data or share it with advertisers. We’ll only hand data to the police or a court if the law requires us to.

Some of the companies we use may store or handle your data outside the UK. When they do, we use the safeguards UK data protection law requires. Your data is encrypted when it travels between your device and us (in transit) and when it’s stored (at rest). Only the people who need access to keep Revisia running have it. They can’t open your notes unless you report a problem and give permission.

• Files and sessions you delete: removed straight away.
• Your account: kept while it’s open. Deleting it removes your notes, sessions, flashcards and progress.
• After your plan ends: your notes, sessions, flashcards and progress are kept for 24 months, in case you come back. We email you 30 days before deleting them.
• Backups: deleted data clears from backups within 30 days.
• Billing records: kept for 6 years after the payment, because UK tax law requires it. These hold your name, email and payment details, never your notes or sessions.
• Security logs: Placeholder: [RETENTION PERIOD].

You need to be 13 or over to use Revisia. Revisia is designed with the ICO Children’s Code in mind:

• Settings are private by default.
• There are no public profiles and no ads.
• Nothing is shared with other users.
• We don’t use your data to profile you.

If you’re a parent or guardian with a question about your child’s account, email Placeholder: [privacy@revisia.example].

You can:

• See the data we hold about you.
• Correct anything that’s wrong.
• Delete your data. You can do most of this yourself in the app.
• Get a copy of your notes, sessions and progress to take elsewhere.
• Object to how we use your data, or ask us to limit it.

Email Placeholder: [privacy@revisia.example] and we’ll reply within one month. If you’re not happy with our answer, you can complain to the Information Commissioner’s Office at ico.org.uk.

We only use the cookies Revisia needs to work, such as the one that keeps you logged in. Essential cookies don’t need your consent, so there’s no cookie banner. If we ever add anything else, such as analytics, we’ll update this page first and ask you where the law requires it.

If we change this policy in a way that affects you, we’ll email you before the change takes effect. The date at the top shows the latest version.
