Privacy Policy

• Optional account (Google / Apple sign-in): if you choose to sign in, we receive your email address and name from Google or Apple to create your account. Sign-in is never required — every feature works without it.
• Learning progress: practice results, streaks, badges, and bookmarks. Stored on your device; if you sign in, also synced to our servers so you can restore it across devices.
• Usage analytics: anonymous app events (screens opened, questions practised, feature usage) via Google Firebase Analytics and our own event store, tied to a random identifier — used only to improve the App.
• No access to your camera, microphone, contacts, or location. No advertising SDKs.

• On your device: progress, bookmarks, and preferences are stored locally and removed when you uninstall the App.
• On our servers (signed-in users only): your synced progress and account identifier, stored with Supabase (hosted in Mumbai, India). Authentication is handled by Google Firebase.

• In the App:Profile → your account → “Delete account”. This permanently removes your account and all synced data from our servers.
• On the web: see Delete your account for the request steps if you no longer have the App installed.
• Signing out (without deleting) keeps your synced data.

• Google Firebase (authentication, analytics, crash-free operation)
• Supabase (progress sync + app events, Mumbai region)
• Cloudflare (content delivery for textbooks and PDFs)

Each processes data only to provide the App’s functionality. We never sell your data or share it for advertising.

Any in-app purchases are processed entirely by Apple or Google through their stores. We do not have access to your payment information or billing details.

The App is designed for school students preparing for CBSE exams. We collect no personal information from users who do not sign in, and sign-in collects only the minimum (email, name) needed to sync progress. We comply with COPPA and India’s Digital Personal Data Protection Act, 2023; parents can request deletion of a child’s account at any time via the steps in Section 3.

Synced data is transmitted over HTTPS and stored with industry-standard providers. Server-side progress is accessible only with your own cryptographically-verified sign-in token — never to other users.

We may update this Privacy Policy from time to time. Any changes will be reflected with a new effective date at the top of this page.
