1 Overview & Privacy Commitment

AB Digital Sangam ("we", "our", or "us") is the official developer and publisher of the AB Calendar: Daily Organizer application (Package: com.abcalendar.app).

We built this application as a utility for Islamic lifestyle organization, Gregorian-Hijri-Bikrami date management, astronomical prayer timings, and personal daily scheduling. We understand the paramount importance of user privacy. Our application operates strictly under a no-tracking and zero-data-harvesting policy. We do not sell, rent, monetize, or disclose your personal information to third parties.

✨

Core Principle: Your notes, schedules, settings, and location calculations remain exclusively under your control on your personal mobile device.

2 Device Permissions & Data Handling Disclosures

To deliver accurate Islamic prayer alerts, Qibla compass bearing, and offline reminders, the application requests specific Android permissions. Below is the complete and transparent explanation of each permission:

📍 Precise & Approximate Location ACCESS_FINE_LOCATION ACCESS_COARSE_LOCATION

Why we use it: When granted by the user, the app retrieves your device's geographical latitude and longitude strictly on your local device to compute accurate astronomical Islamic Prayer Times (Fajr, Dhuhr, Asr, Maghrib, Isha, Sehri & Iftar) and calculate the accurate Qibla compass direction towards the Holy Kaaba.
Data Privacy: Your GPS location is never transmitted to external servers, never stored remotely, and never shared with third parties. All calculations are executed instantly on-device using our local calculation engine.

🔔 Push & System Notifications POST_NOTIFICATIONS

Why we use it: On Android 13 (API level 33) and above, this permission allows the application to show Azan alerts, prayer time reminders, morning Islamic status quotes, and administrative community announcements.
User Control: You can completely customize, mute, or turn off notifications anytime in the App Settings or via Android System Settings.

⏰ Exact Alarms & Wake Lock SCHEDULE_EXACT_ALARM USE_EXACT_ALARM WAKE_LOCK

Why we use it: Required by the Android AlarmManager to fire offline local Azan alarms, Sehri wakeup reminders, and personal calendar notes at the exact scheduled minute, even when the device is locked, idle, or when the app is completely closed.

🔄 Boot Persistence & Haptic Alerts RECEIVE_BOOT_COMPLETED VIBRATE

Why we use it: Required to automatically re-register and restore your scheduled Azan, Sehri, and diary alarms whenever your smartphone restarts or reboots. The vibration permission provides timely haptic feedback during prayer reminders.

💾 Local Device Storage & Preferences SharedPreferences / SQLite

Why we use it: Your language selection (Urdu, Hindi, English, Nepali, Arabic), chosen visual themes, personal diary entries, and custom calendar schedules are stored exclusively on your device's local internal storage. No personal notes are uploaded to any cloud database.

  • Open-Meteo Weather API: Used to display live temperature and ambient weather conditions on the calendar dashboard. Only non-personally identifiable coordinates are transmitted in standard HTTPS queries.

  • Uninstall Deletion: Uninstalling the application automatically deletes 100% of the data, files, and preferences stored by the app on your smartphone.
