Plain Apps

Privacy policy: Sleep Timer [NAME]

Android app · Last updated:

1. In short

The app does not collect, transmit or share personal data. It has no internet permission, no account, no ads, no analytics and no third-party SDKs that collect data. Everything it stores stays on your phone.

2. Who is responsible

Provider of the app and controller within the meaning of the GDPR: Plain Apps, Residenzstr. 5, 80333 Munich, Germany, plainapps@tuta.com

Contact for privacy questions: plainapps@tuta.com

The full provider details are in the .

The data the app keeps on your phone is not sent to us. We do not receive it.

3. What the app stores on your phone

  • Your settings and presets (names, minutes, fade lengths, switches), the optional nightly start (time, weekdays), and the state of a running timer.
  • Short records of things the app changed and must give back (for example your previous volume, your previous screen timeout or brightness, a Do Not Disturb rule it switched on), so it can restore them.

This data is kept in the app's private storage. We never receive it.

The app also writes short technical messages (for example which step of the timer ran, or the name of a media player it paused) to Android's system log on your phone. We never receive them.

4. Optional special access

The app asks for these only when you switch on a feature that needs them, after an explanation screen where you must tap “Agree”. You can refuse and keep using the timer, and turn each access off at any time in Android Settings.

  • Accessibility service (Lock screen at end; Go to Home screen first; the dark layer of Goodnight): used to lock the screen like the power button, to go to the Home screen, and to draw a dark layer. The service declares no event types and cannot read window content. It does not read, record or transmit anything on your screen or anything you type.
  • Notification access (Enhanced compatibility): used to list which media players are playing so the app can pause them. The app does not read, store or transmit the content of your notifications. (Android hands a notification-access app the ability to receive notifications; the app contains no code that reads or keeps them.)
  • Do Not Disturb access: used to turn on the app's own Do Not Disturb rule “Sleep timer” when a timer starts and to end it at your chosen time.
  • Modify system settings: used to set the screen timeout to 15 seconds after the pause, or lower the brightness for Goodnight, and to restore your value once the screen is off.

5. Other permissions and why

  • Notifications (Android 13 and newer): to show the countdown and its buttons. If you refuse, the timer still runs.
  • Foreground service, exact alarms, wake lock, boot: so the timer ends on time, also while the phone is idle, runs reliably, and can re-arm the optional nightly start and the Do Not Disturb end after a restart.
  • Vibration: one short buzz that confirms an optional shake-to-extend.
  • Names of installed media players: the app can see which media players are installed only to show which one it paused (“Paused [player]”). This is used on screen only, not stored or sent. The app does not use the “see all installed apps” permission.

The app does not use internet access, location, contacts, camera, microphone or storage permissions.

6. Android backup

Android may include the app's stored data (settings, presets and timer state) in your own Google account backup if you have backup switched on. That is handled by Android under your own Google account settings. We do not receive it and cannot read it. You can turn backup off in Android Settings.

7. Third-party code and services

The app uses only libraries that run inside it: AndroidX (including Jetpack Compose and DataStore) and Kotlin coroutines. None of them sends data anywhere. The app contains no advertising, analytics or crash-reporting code.

Android's accessibility, notification and Do Not Disturb features are parts of Android that run on your phone; the app uses them only as described above.

8. No tracking, ads or analytics

The app has no account, no advertising, no analytics, no crash reporting and no tracking. It does not use an advertising ID. We do not build profiles and make no automated decisions about you.

9. Legal basis

Nearly everything the app does happens on your phone, and we never receive it. Where that is processing of personal data for which we are responsible, the legal basis is:

  • Art. 6(1)(b) GDPR: the app functions you ask for (the app is used under the terms of the store you got it from).
  • Art. 6(1)(a) GDPR: your consent, for optional features that are off until you switch them on and for which your phone asks your permission. You can withdraw consent at any time by switching the feature or the permission off in the app or in your phone's settings. Processing that already happened stays lawful.

10. How long data is kept, and how to delete it

The data stays on your phone until you delete it. We keep no copy. Uninstalling the app deletes it; you can also clear the app's storage in Android's app settings.

11. Children

The app is not directed at children and collects no data from anyone, including children.

12. Your rights

Under the General Data Protection Regulation (GDPR) you have the right to:

  • information about and access to your data (Art. 15),
  • correction (Art. 16),
  • erasure (Art. 17),
  • restriction of processing (Art. 18),
  • notification of recipients about corrections, erasure or restriction (Art. 19),
  • receive your data in a common format and pass it on (data portability, Art. 20),
  • object to processing (Art. 21), and
  • withdraw a consent you gave (Art. 7(3)).

You also have the right to complain to a data protection supervisory authority (Art. 77), for example the one where you live. The app makes no decision about you based only on automated processing (Art. 22).

We receive no personal data through the app, so we normally hold nothing about you that we could give out, correct or delete. Removing the app removes its data from your phone.

If you still want to use one of these rights or have a question, write to the contact address in section 2. We answer within one month (Art. 12(3) GDPR).

13. App stores

If you install the app through Google Play, the store processes your download and account under its own privacy policy. We receive only aggregated statistics from the store, no personal data.

14. Changes

If this policy changes, the new version is published at this address with a new date. If a future version of the app starts to access more than described here, this policy is updated before that version is released.
