Cappy turns photos of your study notes into short quiz games. This page explains, in plain words, what we collect, why, and what you can do about it.

Who we are

Cappy (cappy.in) is run by Rahul Kumar in India. For anything about your data, email team.cappyclub@gmail.com.

What we collect and why

• Your Google sign-in details. If you sign in with Google, we receive your name, email address and profile photo. We use them to create your account, show your name in the app and keep your progress across devices. We don't get your Google password or access to anything else in your Google account.
• Photos of your notes. When you snap or upload a page, the photo is sent to our AI provider, Anthropic (Claude), which reads it and writes questions. Cappy does not store your photos on its servers. Anthropic does not use them to train its models, and may keep them for a short time for safety checks as described in its own policies.
• Your progress. Things like coins, streaks, scores, quiz sets and which questions you got right or wrong, so the app can plan your revision and avoid repeating questions.
• Basic technical information. Like most websites, our hosting provider records standard details such as your IP address, browser type and the time of a request. We also log how many AI requests are made and what they cost, without the photo or question content.
• Messages you send us. If you use Help & feedback, we keep your message and your email so we can reply. If you leave "Include app details" on, we also get your phone and browser type, which screen you were on and recent error messages. Never your photos or notes.
• Error reports. If something in the app breaks, it sends us a short error report on its own: what went wrong, which screen, and the same app details as above, so we can fix it. Never your photos or notes.

Your camera

Cappy only uses your camera while the Snap screen is open, and only after you allow it. The live picture is checked on your own phone to find the edges of the page. Nothing is sent anywhere until you press the shutter or pick a photo.

What stays on your device

Some things are saved only in your browser on your phone, for example your settings, recent progress and the questions made from your recent photos (kept for up to 7 days so the same photo doesn't need to be read twice). Clearing your browser's site data removes them.

Who we share data with

Only the services that run Cappy, and only what they need:

• Google, for signing in.
• Supabase, our account and database provider (servers in Singapore).
• Anthropic, our AI provider, for reading note photos and writing questions.
• Vercel, our website hosting provider.

We don't sell your data, share it with advertisers or use it for ads. We would only share it with authorities if the law requires us to.

Students under 18

Cappy is made for school and exam students. If you're under 18, please use Cappy with your parent's or guardian's permission. Parents and guardians can email us at any time to see or delete their child's data.

Keeping and deleting your data

We keep your account and progress for as long as you use Cappy. To delete your account and everything linked to it, email team.cappyclub@gmail.com from the email you signed in with. We'll delete it within 30 days and confirm by email. You can also remove Cappy's access from your Google account settings at any time.

Keeping data safe

Data is sent over encrypted connections (HTTPS), and each student's records are locked so that only they can read them. No system is perfectly secure, but we take reasonable care to protect your information.

Changes to this policy

If we change this policy, we'll update the date at the top. If a change is important, we'll tell you in the app.
