Privacy Policy

Last updated: May 28, 2026

1. Who we are

Qoum ("the app", "we") is published by Samir Seduk, contactable at [email protected]. This Privacy Policy explains how Qoum handles data when you use the app on Android or iOS.

2. Data we do NOT collect

• No name, email, phone number, or any other personal identifier.
• No user accounts. You don't sign up. There is nothing to sign in to.
• No advertising identifiers (IDFA, AAID).
• No third-party analytics SDKs (no Mixpanel, no Amplitude, no Facebook SDK, etc.).
• No location history. Your coordinates are used once for prayer time calculation, then stay on your device.
• No audio recordings sent to servers. Voice messages you record stay on your device only.
• No contacts, no photos, no calendar access.

3. Data stored ONLY on your device

The following stays exclusively on your phone (in local storage). We never send it anywhere:

• Your location (latitude, longitude, city name, timezone) used to compute Fajr time offline.
• Your prayer history (which days you completed Fajr) and streak.
• Your settings (calculation method, alarm mode, language, theme, sound choice).
• The guardian's phone number, if you enabled the Guardian feature. It is read only when the guardian is triggered by your phone.
• Your custom recorded wake-up message or imported audio file, if you set one.
• The QR code identifier you registered, if you chose the QR challenge.

4. Anonymous data we DO send to servers

To show the "X people rising for Fajr tonight" community counter, the app sends one anonymous ping per day to our Firebase Firestore backend (operated by Google). Each ping contains:

• The date.
• Whether an alarm was scheduled and whether Fajr was confirmed done.
• The city name (e.g. "Paris", "Cairo") and the challenge type used (math / shake / QR).

These pings are fully anonymous. They do not contain any device ID, user ID, IP-linked identifier, or way to trace back to you individually. They are aggregated into city-level and global counters.

5. Permissions we request

• Location · to compute exact Fajr prayer time for your city. Used locally, never uploaded.
• Camera · only if you enable the QR Code wake-up challenge.
• Microphone · only if you choose to record a custom wake-up message.
• Motion sensors · only if you enable the Shake wake-up challenge.
• Notifications · to ring the alarm at Fajr time.

You can revoke any of these in your phone's system Settings at any time. The corresponding features will simply stop working.

6. Third-party services

Qoum uses the following third-party services:

• Firebase Firestore (Google) · stores the anonymous daily counters described in section 4. See Google's privacy policy at policies.google.com/privacy.
• Open-Meteo geocoding API · used only when you search for a city by name in the city picker. The request contains only the text you type, no identifiers.

7. Children

Qoum is suitable for all ages and complies with COPPA. The app does not collect personal data from anyone, including children under 13.

8. Data retention

Data stored on your device is removed when you uninstall the app. Anonymous server counters are kept indefinitely as aggregated statistics, since they contain no personal information.

9. Your rights

Because Qoum holds no personal data tied to you, there is nothing personal to access, rectify or delete server-side. You can erase all local data at any time by uninstalling the app or clearing its storage in your phone's system Settings.

10. International users

Firebase servers are located in Europe (region europe-west1). Visitors from outside the European Union are subject to the same anonymous policy.

11. Changes to this policy

We may update this policy occasionally. The "Last updated" date at the top of this page reflects the latest revision. Material changes will be highlighted on the Qoum website.
