Privacy policy for metronome, just cleaner, by Qi Liu.
Effective October 5, 2026.

Data in the app

The app does not collect or send personal data to us. It has no account system, advertising, tracking, or third-party analytics SDKs. No microphone recording is used.

Saved on your device

Preferences and rhythm presets are stored locally on your device. They are not uploaded to our servers. Removing the app removes its local data; device backups are controlled by your Apple settings.

If you contact support

If you email us, we receive your email address and whatever you choose to include so we can respond. We do not use support correspondence for advertising or sell it. You can ask us to delete correspondence we control by contacting us.

This website and Apple

This policy describes the app. The website hosting provider and email provider process information needed to serve pages and deliver messages. Apple independently handles App Store downloads and any platform diagnostics under its own privacy policies and your settings.

Changes and contact

We will update this page if the app’s privacy practices change. Questions? Contact Qi Liu.
