Privacy Policy

Last updated: August 2026

This policy explains what information Revyy ("we", "us") collects when you use our website and app, how we use it, who we share it with, and the choices you have. We have tried to describe what actually happens rather than list every possibility. If anything is unclear, email us at support@revyy.app.

1. Information we collect

Account details: when you sign up, our authentication provider (Clerk) collects your email address and either a password or your Google sign-in, plus a display name if you provide one.
Study material you upload: the PDFs, images, photos, pasted text (including sets you import from Quizlet) and audio or video recordings you submit so we can generate a quiz, flashcards or an exam from them.
Your study progress: if you are signed in, we save the data the app produces, your review deck, quiz and exam scores, study plans, per-topic progress and any exam date you set, to our database so it syncs across your devices.
Usage and plan data: counters such as how many questions and mock exams you have generated today, and whether you are on the Free or Pro plan, so we can apply plan limits.
Payment data: if you subscribe to Pro, your card details are collected and held by our payment provider (Stripe). We never see or store your card number, only your subscription status.
Messages you send us: the name, email and message you submit through the contact form or the in-app report tool.
Settings stored on your device: your language, theme and a local copy of your study data and counters, kept in your browser's local storage.
Technical data: standard server logs such as IP address, browser type and approximate region, used to keep the service secure and working.

2. How we use your information

To generate quizzes, flashcards and mock exams from the material you provide.
To save and sync your study progress across your devices when you are signed in.
To apply Free and Pro plan limits and process subscriptions.
To respond to your support messages.
To keep the service secure, prevent abuse, and fix problems.
On the Free plan, to show advertising (see section 5).

3. Your uploaded material, transcription and AI generation

To build your quiz, the material you upload is sent to Anthropic's Claude API, which reads it and writes the questions. Before that, we run a quick automated safety check on the content so that clearly explicit or non-study material is not turned into a quiz.

If you upload an audio or video file, it is first transcribed to text by our transcription provider (AssemblyAI), and only the resulting text is used to generate your quiz. Larger uploads on the Pro plan, including audio and video, pass through a temporary file store (Vercel Blob), which we delete as soon as the file has been forwarded for processing. Sets you import from Quizlet are read in your own browser and never leave your device except as the same study text described above. We do not keep copies of your uploaded files on our own servers.

So that Revyy can build a cumulative "quiz me on everything" review across what you have studied, we keep a short AI-written summary of each set as part of your study data. These summaries are a brief digest of the material, not the original files or their full text, and you can remove any of them, or all of them, from your study library whenever you like.

Anthropic and AssemblyAI process your content only to provide these features, under their own terms, and do not use it to train their models.

4. Shared quizzes

If you create a share link for a quiz, we store that quiz's questions, the name shown on it (taken from the first part of your email address) and the scores of people who take it, so that anyone with the link can play it and see the leaderboard. A shared quiz is accessible to anyone who has the link. If you want a shared quiz removed, email us and we will delete it.

5. Advertising

Free-plan pages may display ads through Google AdSense. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this and other websites. You can review and turn off personalised advertising at Google's Ads Settings, opt out of third-party vendor cookies at aboutads.info, or read more in Google's advertising policy, as well as through your browser or device controls.

6. Who we share data with

We do not sell your personal data. We share it only with the service providers we rely on to run Revyy, and only for that purpose:

Clerk, accounts and sign-in.
Neon, our database (your study data, plan and usage counters, shared quizzes).
Anthropic, the AI that generates your quizzes from your material and runs the content safety check.
AssemblyAI, transcribing the audio and video you upload.
Stripe, payment processing for Pro.
Vercel, hosting and the temporary file transfer described above.
Google AdSense, advertising on the Free plan.
Resend, delivering your contact-form messages to our support inbox.

7. Data retention

Your study data is kept until you delete it or close your account. Daily usage counters reset each day. Contact messages remain in our support inbox. Shared quizzes stay available until you ask us to remove them or you close your account.

8. Your rights and choices

Access, correct or delete the personal data we hold about you.
Delete your account, which removes your synced study data.
Clear the settings and cache stored on your device by clearing your browser data.
Opt out of personalised ads through Google's Ads Settings.

To make any of these requests, email support@revyy.app.

9. Children

Revyy is intended for students old enough to hold an account under their local rules (generally 13, or 16 in parts of the EU). It is not directed at younger children, and we do not knowingly collect their data.

10. Changes and contact

We may update this policy as the product changes, and will update the date above when we do. For any privacy question or request, email support@revyy.app or visit our Contact page.
