Privacy policy

Schlafschaf · Last updated 21 October 2026

Schlafschaf is an iPhone app made by Vladyslav Zaiets. This policy explains what happens with your data when you use it. The short version: the app does not collect personal data and sends nothing to us.

No account, no ads, no analytics, no tracking.
Everything you do in the app stays on your iPhone.
Nothing is sent to us.
The purchase is handled entirely by Apple.

What the app collects

Nothing. Schlafschaf has no account or sign-in, no analytics, no advertising, no tracking and no third-party SDKs. It does not connect to any server of ours. The following is stored only on your iPhone: your settings (breathing pattern, timer, sound, voice, brightness). It is deleted together with the app. If you back up your iPhone to iCloud or a computer, Apple includes this data in the backup, as with any app.

Purchases

The one-time purchase "Schlafschaf Full" is handled entirely by Apple through the App Store. We never see your name, payment details or Apple Account. How Apple handles purchase data is described in the Apple Privacy Policy. "Restore purchases" asks the App Store on your device whether the purchase exists; nothing is sent to us.

Voice

The counting voice uses the speech voices built into iOS and runs on your iPhone; the gentle breathing pulse uses the phone's haptics. Sound continues after the screen locks only so the timer can finish.

Permissions

The app asks for no permissions: no camera, microphone, photos, location, contacts, health data or notifications, and no permission to track you across apps.

Diagnostics from Apple

If you turned on "Share With App Developers" in iPhone Settings > Privacy & Security > Analytics & Improvements, Apple may share anonymous crash and usage statistics for this app with us through App Store Connect. You control this setting; the data does not identify you.

Children

The app collects nothing from anyone, including children.

Your rights

Because we hold no data about you, there is nothing for us to show, correct or delete; deleting the app removes everything it stored. If you write to us by email, we use your address and message only to answer you and delete the conversation on request. You may also contact a data protection supervisory authority.

Changes

If this ever changes, the updated policy will be published on this page before the app update that brings the change.
