Privacy Policy
Last updated: April 2026
Overview
DuaDhikr is built with privacy as a core principle. All personal data — your prayer settings, mood check-ins, dua history, and verse history — is stored exclusively on your device. We do not operate a user database and cannot access any of your personal data.
DuaDhikr does not require an account and does not collect your name or email address. Any data we do collect is used only to keep the app working and to improve it. It is never sold, rented, or shared for advertising.
Data We Collect
Stored on your device only (never sent to us):
- Onboarding survey answers (gender, prayer habits, goals)
- Mood and closeness ratings from daily check-ins
- Your dua and Quranic verse history
- Subscription status and app preferences
- Your Screen Time app selection — stored by Apple as opaque tokens. We never know which apps you chose to block.
Collected automatically:
- Device model and iOS version
- App usage events (screens visited, feature interactions), linked to a pseudonymous device identifier. Used only to improve the app.
- IP address, logged briefly on our server for security purposes.
API Calls
When generating your daily dua, the app sends a context payload to our API. This includes your mood, closeness rating, and a brief spiritual profile — along with a pseudonymous device identifier used to verify your subscription. This context is passed to OpenAI to generate your dua and is not stored in any database on our end.
Third-Party Services
The following services process limited data as part of the app's operation. None of them receive your name, email, or any data that identifies you personally.

Analytics events are retained for up to 12 months. We never sell, rent, or share your data with third parties for advertising or any other commercial purpose.
