Privacy Policy
Last updated 20 August 2026 · Sleeper (com.sleeper.turnoff.phone.timer.pickerry) · Published by Bract Studio
Sleeper runs your sleep routine on your phone. It does not collect your data, there is no account to create, and no server of ours receives anything from the app.
What we collect
Nothing.
- No account, sign-up, or login.
- No analytics, telemetry, or usage statistics.
- No crash reporting.
- No advertising, ad IDs, or third-party tracking SDKs.
- No profiling, and no automated decision-making about you.
We do not operate a server that receives your information. There is no Bract Studio account, no cloud sync, and no database anywhere holding your data.
What stays on your device
Sleeper keeps a small amount of information so the app works between sessions. All of it is written to the app's own private storage on your phone, and none of it is transmitted.
| What | Why | Where it goes |
|---|---|---|
| Your timers and schedules | To run the sleep routine you set up | Device only |
| Your sleep log | To show your sleep patterns over time | Device only |
| Sound and app preferences | To remember how you set the app up | Device only |
Uninstalling Sleeper deletes all of it. There is no copy anywhere else and no way to restore it, so export anything you want to keep before you uninstall.
Locking your screen
Android does not let an ordinary app turn your screen off. Sleeper uses Android's Device Administrator API, and only ever calls the single “lock now” action when your timer expires.
Sleeper does not use the Accessibility Service, which is the other way an app can lock a screen. It cannot read your screen, your text fields or anything you type.
Device Administrator is off until you switch it on, and you can revoke it at any time in Settings → Security → Device admin apps. Android requires you to revoke it before the app can be uninstalled.
Permissions, and what each one is for
- Device administrator — performs the screen lock when your timer ends. That single action, nothing else.
- Modify audio settings — lowers your media volume at the end of the timer.
- Alarms and reminders — lets your timer and daily schedules fire at the exact time you set, even when the app is closed.
- Notifications — shows the running timer so you can see it counting down and cancel it.
- Run at startup — restores your daily schedules after you restart your phone, so a routine you set does not silently stop working.
- Keep the device awake and vibrate — used while a timer or sound is running.
Internet access
Sleeper declares Android's internet permission, so we should say plainly what it is for. It is used to open links you tap yourself — the studio website and this privacy policy — and by Google Play for app updates. The calming sounds are bundled inside the app and play from your device; they are not streamed.
The app does not contact any Bract Studio server, because there isn't one. Nothing about how you use Sleeper is reported to us.
Children
Sleeper is not directed at children, and collects no data from anyone — including children under 13, or the equivalent age in your country. Because we collect nothing, there is nothing to delete on request.
Data sharing and sale
We share nothing, because we hold nothing. We have never sold user data and have no mechanism to do so.
Your rights
Privacy laws such as the GDPR and CCPA give you the right to access, correct, export or delete the personal data a company holds about you. Bract Studio holds no personal data about Sleeper users, so there is nothing for us to return or erase.
Everything Sleeper touches lives on your own device and is under your control: revoke any permission in Android Settings, or uninstall the app to remove it all at once.
Google Play compliance
Sleeper complies with Google Play's Limited Use requirements. Data the app accesses on your device is used solely to provide features that are visible to you in the app, is processed locally on the device, is never transferred to any server, and is never used for advertising, profiling or credit assessment. It is never sold.
