Data Collection

The Four Books App does not collect, store, or transmit any personal data to external servers. All app data (bookmarks, reading preferences, viewed verses) is stored locally on your device and synced via Apple’s iCloud service to your other devices if iCloud is enabled.

Third-Party Services

This app does not use any third-party analytics, advertising networks, or tracking services.

iCloud Sync

If you have iCloud enabled, your bookmarks and reading progress sync across your devices through Apple's iCloud Key-Value storage. This data is governed by Apple's privacy policy.

In-App Purchases

Purchases are processed through Apple's App Store. Payment information is handled entirely by Apple and is not accessible to us.

Data Retention & Deletion

Since no data is collected by us, there is no data to delete. To remove local app data, uninstall the app from your device.
