Privacy Policy

1. What we collect

When you sign up with Google, we receive your name, email address, and profile picture. We also collect study activity data (formulas viewed, quiz scores, bookmarks, streaks) to personalise your revision experience.

2. How we use it

• Track your revision progress and streaks
• Save your bookmarks and quiz history
• Send revision reminders (WhatsApp, if you opt in)
• Improve content quality based on aggregate usage patterns

3. Data storage

Your data is stored securely on Supabase (PostgreSQL) with row-level security. Each user can only access their own data. We do not sell or share your personal information with third parties.

4. Cookies and tracking

We use essential cookies for authentication sessions. We do not use third-party advertising trackers. Anonymous view counts are tracked using a fingerprint hash (IP + User-Agent) for the free content gate; this data is not linked to your identity.

5. Your rights

You can delete your account and all associated data at any time by contacting us. You can also export your study data on request.
