1. Information We Collect

Isabella is an A-Level past-paper learning tool. To provide paper download and device management services, we process the following information:

  • Device Identifier: A random device ID generated on first launch, used to identify devices, count access, and enforce anti-abuse rules (e.g., temporary rate limiting after 40 papers within one hour). It cannot be used to identify you.
  • Sign in with Apple data: When you choose "Sign in with Apple", we only receive your name and email (used to sync favorites). We never obtain or store your Apple password.
  • Favorites & browsing history: Stored on your device and synced to our server when signed in, for use across devices.
  • Usage statistics: Anonymous statistics such as access time, device model, OS version and paper IDs downloaded, used for service stability. No personally identifiable content.

2. How We Use Information

  • Provide core features: paper browsing, downloading, favorites sync;
  • Protect server security and prevent abuse;
  • Improve the product (e.g. loading performance).

3. Information Sharing

We do not sell, rent or disclose your personal information to third parties, except as required by law. Papers are served from our own servers.

4. Storage & Security

Data is stored on our managed servers with access control and rate limiting. Server access is protected by device identifiers and administrator credentials.

5. Your Rights

You may delete favorites and browsing history on your device at any time. Deleting the app removes all local data. To delete server-side data linked to your device, contact us (below); we will respond within 30 days.

6. Children's Privacy

This app targets A-Level learners and may be used by minors. We do not knowingly collect children's personal information; the device identifier is used only for abuse prevention, never profiling.

7. Third-Party Content

Papers are compiled by examination boards (e.g. Cambridge International, Pearson Edexcel); their copyrights belong to the boards and rights holders. This app does not claim ownership of any papers; materials are collected from public channels for study purposes only.

8. Policy Changes

We will update this page and note the last-updated date when the policy changes.
