Privacy Policy

Effective date: November 14, 2026 · Package ID: com.anonymous.sleep_timer

In short: Sleep Timer runs completely offline on your device. It does not collect, store, or share personal data, and it contains no ads, analytics, or network permissions.

1. Overview

This Privacy Policy describes how the Sleep Timer Android application, developed by Ismail Courr, handles information when you use the app.

2. Information We Collect

Sleep Timer does not collect, transmit, sell, or share any personal information, usage analytics, device identifiers, or location data.

The app does not request Android's INTERNET permission and cannot send data off your device.

Active countdown state exists only in memory while a timer is running. The only persistent local storage used by the app is a private on-device preference file (sleep_timer_preferences) storing boolean flags indicating whether the optional Google Play review prompt has been shown or dismissed. Cloud backup is disabled (allowBackup="false").

3. Permissions Used

Sleep Timer requests only the Android permissions needed to run a countdown reliably and pause media when it finishes:

POST_NOTIFICATIONS — Displays the ongoing countdown notification while a timer is active and a brief completion notice when playback pauses (Android 13+).
FOREGROUND_SERVICE & FOREGROUND_SERVICE_MEDIA_PLAYBACK — Keeps the timer running reliably when the app is in the background or the screen is off.
WAKE_LOCK — Ensures the countdown finishes on time while the device sleeps.
VIBRATE — Supports standard system notification behavior when enabled by your device settings.

When the countdown reaches zero, Sleep Timer uses Android's AudioManager locally to fade media volume out, request transient audio focus, and dispatch a media pause key event to stop active audio or video players.

4. Third-Party Services & External Links

Sleep Timer does not include third-party advertising networks, analytics SDKs, or crash-reporting libraries.

If you choose to tap the optional "Review on Google Play" button inside the app, Android opens the Google Play Store listing for Sleep Timer. Any interaction with Google Play is governed by Google's own Privacy Policy.

5. Data Retention & Deletion

Because no data is collected on any server, there is no remote account or stored data to delete. Uninstalling Sleep Timer removes all local preferences from your device immediately.

6. Children's Privacy

Sleep Timer is intended for general audiences and does not collect personal data from anyone, including children under 13.

7. Changes to This Policy

If this Privacy Policy is updated, the revised version will be posted at this URL with an updated effective date.
