Frequently Asked Questions

The alarm did not fire at the prayer time. What should I check?

Make sure the toggle for that prayer is switched on in the app. Also check that Sajdah Silent is not restricted by Android battery optimisation — go to Settings → Battery → Battery optimisation and set Sajdah Silent to Not optimised. Some device manufacturers (Samsung, Xiaomi, Huawei) apply aggressive background-kill policies that can prevent alarms from firing.

Will the alarms still work after I restart my phone?

Yes. Sajdah Silent listens for the device boot event and automatically reschedules all active alarms when your phone restarts.

How do I change a prayer time?

Open the app, tap the prayer name, and use the time picker to set the correct time for your local mosque or calculation method. The change is saved and the alarm is rescheduled immediately.

Can I set different silent durations for each prayer?

Yes. Each prayer has its own silent-duration setting. Jumuʼah defaults to 60 minutes; daily prayers default to 20 minutes. You can adjust each one independently.

Can I enable only auto-silence or only auto-restore for a prayer?

Yes. Each prayer has two independent toggles: Auto-silence (switches the phone to vibrate at prayer time) and Auto-restore (returns the ringer to its previous level after the silent duration). You can turn either on or off for each prayer separately.

Does the app need an internet connection?

No. All prayer times are set manually by you and stored locally on your device. Sajdah Silent works fully offline.

Does the app collect any of my data?

No. See the Privacy Policy for full details. In short: nothing is collected, transmitted, or shared.

Why does the app need the “Wake lock” permission?

Android can suspend the CPU when the screen is off to save battery. The WAKE_LOCK permission lets Sajdah Silent briefly keep the processor awake while it changes the ringer mode and posts a notification the moment an alarm fires. Without it, the phone could fall back asleep mid-operation and miss the silent or restore step entirely.
