Privacy Policy — DeepQuran
- Last updated: April 30, 2026
DeepQuran ("the app", "we", "us") is a Quranic linguistic analysis tool published by Ahmed Alla Eddine Ouared. This policy explains what data the app handles and how.
TL;DR
- *We do not run any server. The app does not collect, transmit, or store any of your data on our infrastructure.
- *Everything stays on your device. Personal dictionary, bookmarks, study notes, settings, and reading position are saved locally in app storage only.
- *Your AI API keys never reach us. They are stored in your device's secure storage (Keychain on iOS, EncryptedSharedPreferences on Android via expo-secure-store) and sent directly from your device to the AI provider you chose.
