Your privacy matters. This app is built so that your data stays on your device.
1. We do not collect personal data
No sign-up and no account are required.
We do not collect or upload your name, email, phone number, location, contacts, photos, or advertising identifier.
We include no third-party analytics or advertising SDKs, and we do not track you.
The app does not connect to the internet and has no developer server.
2. Data stays on the device
The score for the current run stays in memory and is not uploaded.
The high score and language choice are stored locally on your device with UserDefaults. We cannot read them, and they do not sync to another device.
Uninstalling the app or deleting its data removes these local records.
3. Sound and haptics
A short built-in sound and one system haptic play when a run ends.
Audio uses the system ambient session and follows the mute switch. We do not use the microphone and we do not record audio.
4. Purchases
This version has no in-app purchases, subscriptions, or ads, so we do not process payment information.
5. Children's privacy
We do not knowingly collect information from children. Because we collect no personal data, using the app does not send a child's personal information to us.
6. Changes
If this policy changes, we will update the "Last updated" date on this page.
