Privacy Policy

Last updated: September 28, 2026

Quartets doesn't collect personal data. There is no account, no analytics, no advertising and no tracking.

What stays on your device

Your games in progress, finished games, streak, statistics and settings are stored only on your iPhone. The widget reads the same data from a shared container on the device. Deleting the app deletes this data.

Purchases

Subscriptions and the Lifetime purchase are handled by Apple through the App Store. We never see your payment details. The app only asks the App Store whether Unlimited is active.

Notifications

If you turn on the daily reminder, the app schedules a local notification on your device. Nothing is sent to a server.

Children

The app doesn't collect data from anyone, including children.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions: shchukavlad4@gmail.com.
