Vakt Privacy Policy

Last updated: 24 October 2026

This policy explains how the Vakt (Prayer Times) Android app (com.setrevo.prayer), published by Setrevo, handles data. Data controller: Setrevo. Contact: nooitwolf@gmail.com.

Short summary

Vakt does not collect or store user data. There is no account, no advertising, no analytics and no telemetry. Prayer times are calculated on your device. If you grant location permission, your location is used to calculate prayer times and qibla direction and never leaves your device for that. The app works fully offline; the internet is used only for the "Quote of the day" screen (no personal data). The "Nearby mosques" button does not fetch data inside the app: when you tap it, it opens your phone's map app with a "mosque" search, and Vakt sends no location or any other data. Home screen widget and lock screen notification data also stays only on your device. Prayer tracker and dhikr counts are also kept only on your device.

Data processed and stored on your device

The following data is kept only on your device, in the app's private storage (Android SharedPreferences), and is not sent to Setrevo or any other server:

  • Selected location: the name, coordinates and time zone of the place you pick through city, district or town search or find with GPS, as needed to calculate prayer times
  • Settings: calculation method, Asr (Shafi'i/Hanafi) choice, per-prayer minute adjustments, reminder preferences, Hijri day adjustment, language, theme, layout and colour palette, numeral format and lock screen notification preference
  • Quote of the day cache: the last downloaded quote list and when it was last refreshed
  • Prayer tracker and dhikr records: prayed and qadaa marks, streak and qadaa counts, dhikr counters, targets and daily totals. Prayer tracker and dhikr counts are stored only on your device; they are not sent to any server, backed up by Setrevo or shared
  • Widget and lock screen data: the next prayer, countdown and style artwork shown in the home screen widgets and the lock screen notification; it is produced from the times calculated on your device and is shared only on your device, between the app and the widgets

Location

Location permission is optional. If you do not grant it, you can choose a city, district or town by searching manually. If you grant it, location is read while you use the app, only to calculate prayer times and qibla direction and to find the name of the nearest place (city, district or town) in the offline city database on your device. The app does not request location in the background. Location is not sent to any server and is not handed to the map app opened by the "Nearby mosques" button (see below). Location is not sold and is not used for advertising or analytics. It is obtained through your device's location system (the Android location service, or Google Play services where available), and the result returns only to the app.

Online request: Quote of the day

The "Quote of the day" screen is the only place where the app goes online.

  • When the screen opens and the list has not been refreshed that day, the app makes a single HTTPS GET request to https://host.setrevo.com/prayer/quotes.json; at most one successful request is made per day
  • The request does not contain your location, your settings, an identifier or any other data about you
  • The downloaded hadith list is cached on your device
  • Without a connection, the app says an internet connection is needed and shows the selection bundled with the app
  • As with any web server, the IP address, time, requested address and standard HTTP headers (for example User-Agent) of the request may be written to the server's technical logs. These records are kept only for operating and securing the server; they are not used for advertising, profiling or analytics and are not linked to anything in the app

Nearby mosques (map app)

The "Nearby mosques" button is optional and free. When you tap it, Vakt opens your phone's map app (for example Google Maps) with a "mosque" search; if the device has no map app, the Google Maps "mosque" search page opens in the browser.

  • What Vakt does not send: Vakt sends no location or any other data, does not go online by itself for this button and stores no mosque data. The link that opens contains no coordinates or identifier, only the search word "mosque"
  • Afterwards: the map app shows nearby mosques, with photos, ratings and directions, based on its own knowledge of your location. From then on the permissions and privacy policy of that app (or of the site opened in the browser) apply; Setrevo does not receive this information and cannot control it

Widgets, lock screen notification and sharing

  • Home screen widgets and lock screen notification: the next prayer, countdown and style artwork are calculated and generated on your device and stay there; nothing is sent to a server. The lock screen notification is optional and off by default
  • Choice of the quote of the day: which quote you see is chosen at random, just for you, on your device; this choice is not reported to any server
  • Sharing the quote of the day: when you tap Share, the content (the quote and the share image generated inside the app) is handed to Android's system share sheet and goes only to the app you choose, for example WhatsApp. Setrevo does not receive it; how that app handles it is governed by its own privacy policy

Data we do not collect

We do not collect name, email, phone number, account details, advertising ID, device ID, contacts, SMS, photos, files, camera, microphone, installed-app list, usage statistics or crash reports.

Third parties

The app contains no advertising, analytics, crash-reporting or social media components. Data is not sold or shared with third parties. The map app you open with the "Nearby mosques" button is a separate app of your choosing; it handles its data under its own privacy policy.

If you install the app from Google Play, Google Play and Android's own services are subject to Google's policies. For example, if Android system backup is on for your device, your app data (settings, selected location, prayer tracker and dhikr records) may be included in your device backup in your Google account. That is a Google device feature; Setrevo cannot access the backup, and you can turn it off in Android settings.

Data sources and attribution

  • The city, district and town database is derived from GeoNames (https://www.geonames.org), licensed under Creative Commons Attribution 4.0 (CC BY 4.0). City search runs on your device, offline

Permissions

  • ACCESS_COARSE_LOCATION / ACCESS_FINE_LOCATION: optional; to find your location with GPS
  • INTERNET: only to fetch the "Quote of the day" list
  • ACCESS_NETWORK_STATE: to tell whether a connection exists for the quote of the day
  • POST_NOTIFICATIONS: to show prayer reminders
  • POST_PROMOTED_NOTIFICATIONS: on Android 16 and later, to show the optional lock screen "Next prayer" notification as a live update (a normal permission; you can turn it off in Android system settings)
  • SCHEDULE_EXACT_ALARM: to fire reminders exactly on time (Android's "Alarms & reminders" permission)
  • RECEIVE_BOOT_COMPLETED: to set reminders up again after the device restarts
  • VIBRATE: for reminder vibration
  • WAKE_LOCK: so reminders can be handled while the device is asleep
  • FOREGROUND_SERVICE / FOREGROUND_SERVICE_SHORT_SERVICE: so the daily background task can reschedule reminders

Location and notification permissions are requested through Android's system dialog and can be revoked in Android settings. The app also works without location permission.

Retention and deletion

The app does not create accounts and does not store user data on Setrevo's servers. Settings, selected location, prayer tracker and dhikr records, quote cache and widget data stay on your device until you delete them or uninstall the app. To delete them on Android, go to Settings → Apps → Vakt → Storage → Clear data, or uninstall the app. Server technical logs are kept only as long as needed for security and operation.

Your rights (GDPR and Turkish KVKK)

Setrevo does not collect personal data that identifies you; the only thing we may hold is the server technical logs described above. The legal basis for those logs is the legitimate interest in running the server securely and reliably (GDPR Art. 6(1)(f); KVKK Art. 5/2-f). Location relies on the permission you give in the Android permission dialog and does not leave your device. The "Nearby mosques" button transfers no data from Vakt; the map app you open with it runs at your choice and is governed by its own privacy policy.

Under GDPR and KVKK Art. 11 you have the right to access, rectify and erase your data, to object to processing and to request information. Write to nooitwolf@gmail.com to make a request. Data on your device is entirely under your control. If you are not satisfied with our answer you may complain to the Turkish Personal Data Protection Authority or to the supervisory authority of the country where you live.

Children

The app is not directed at children and does not knowingly collect personal data from children. It does not collect personal data from any user.

Changes and contact

This policy may be updated when the app's features or the law change. The current date is shown at the top of the page. For privacy questions contact nooitwolf@gmail.com.
