Introduction

Deenly: Prayer, Hadith & Tilawat (formerly known as Ramzan Prayer & Hadees) is a 100% free Islamic application developed by Abdus Salam. We are committed to protecting your privacy. This policy explains how we handle your information when you use our app.

✓ This app is completely free · No advertisements · No in-app purchases

🛡️ WE DO NOT COLLECT ANY PERSONAL DATA

Deenly does not collect, store, or transmit any personal information. All data remains locally on your device. We do not use Google Analytics, Firebase Analytics, or any tracking tools.

Location Permission

The app requests location access for one purpose only:

  • To calculate accurate prayer times based on your current location
  • To determine Qibla direction using your device's compass

Important: Location data is processed entirely on your device. It is NEVER sent to any server, cloud, or third party. You can deny location permission and still use manual location entry.

Qibla Compass

The 3D Qibla compass uses your device's magnetometer and accelerometer sensors. This data is processed locally and is not accessible to us or any third party. No sensor data is ever recorded or transmitted.

🎧 Tilawat (Quran Recitation) Privacy

The Tilawat feature streams Quranic recitations by Sheikh Al Sudais. Audio streaming uses your internet connection but no personal data is collected. We do not track which Surahs you listen to, how long you listen, or any listening patterns. No audio is stored permanently on your device.

Hadith Library

The Hadith collection is stored locally within the app. No internet connection is required to read Hadiths. We do not track which Hadiths you read, your bookmarks, favorites, or how much time you spend in the app. Everything stays on your device.

Prayer Times

Prayer time calculations are performed locally on your device using your GPS coordinates or manually entered location. No location data ever leaves your device. The app uses established Islamic calculation methods (Karachi, MWL, ISNA) which are built into the app.

Smart Alarms & Notifications

The app uses Android's alarm manager to schedule prayer and Sehri/Iftar notifications. No data about your alarm settings or notification interactions is collected. All scheduling is handled locally on your device. The smart alarm system works even in deep sleep mode without sending any data externally.

Permissions Explained

Location: Used only for prayer times & Qibla (local processing only)
