Privacy Policy

Last updated: 29 September 2026 · applies to Tathir for Android (package tathir.shia)

Tathir is a prayer times and worship journal app. It is non-commercial: no ads, no tracking, no analytics, and your data is never sold.

What stays on your device

Your prayer journal, qada counters, fasting records, dhikr counts, settings, and location choice are stored only on your device. All prayer times are calculated on the device itself; the app works fully offline.

Location

You can type a city or use your device’s location once to set your coordinates. With your permission, the app may also compare your current position against your saved one to offer a location update when you travel. Your location is never sent to us or to any server (the Wear OS section below covers your own watch). If you use the online city search, only your typed query (never your position) is sent to Open-Meteo‘s free geocoding service.

Optional cloud sync

Only if you sign in with Google, your journal and qada counters are stored in Google Firebase (Firestore) under your account so you can restore them on a new device. This is entirely optional; the app is fully functional without it.

Deleting your cloud data and account: open the app → Settings → Cloud sync → Delete cloud data, or follow the steps on our data deletion page.

Optional crash reports

Crash reporting (Firebase Crashlytics) is off by default. If you switch it on in Settings → Privacy, anonymous technical crash data (device model, Android version, stack trace) is shared with Firebase to help fix bugs. It never includes your journal, qada, or location. You can turn it off again at any time.

Wear OS watch

If you install Tathir on a Wear OS watch paired with your phone, the phone sends the watch what it needs to calculate prayer times: your location name, your coordinates rounded to about 1 km, and your calculation settings. This goes only to your own watch, through Google Play services’ Wear OS connection, which may relay it via Google’s servers when the watch is not near the phone. Nothing from your journal, qada, or account is sent to the watch, and none of it is sent to us.

Backup files

Settings → Backup saves your journal and qada counters to a file in a place you choose, and can restore from one. The file stays wherever you put it; the app never uploads it.

Calendar

Exporting Islamic events writes to a calendar you explicitly choose, only when you tap export. The app never reads your existing calendar entries.

Permissions summary

Notifications (adhan and reminders), exact alarms (prayer-time precision), location (optional, for prayer-time coordinates), calendar write (optional, for event export), display-over-apps (optional, for the prayer lock). Each is requested only for the stated purpose.
