Privacy Policy

Last updated October 17, 2026

The short version

doesn't collect your personal data. There's no account, no ads and no analytics or tracking SDKs in the app. Your progress stays on your phone.

What the app stores

To run your lessons, the app saves this on your device only:

None of it is sent to us or anyone else. Deleting the app deletes it.

Purchases

Subscriptions are handled by Apple (App Store) or Google (Google Play). We never see your name, account or payment details. The store only tells the app whether your subscription is active. Apple's and Google's own privacy policies cover what they collect.

Notifications

If you turn on reminders, the app schedules them on your device. The same goes for the reminder before your free trial ends. No server is involved.

Microphone

The singing games, Sing to Fly and Note Drop, use the microphone to hear which note you sing. The app asks before turning it on. Sound is analyzed on your phone as you sing and thrown away right after: nothing is recorded, saved or sent anywhere.

Children

The app doesn't collect personal information from anyone, including children under 13.

This website

This site sets no cookies and runs no analytics. Fonts load from Google Fonts, so Google receives your IP address when the page loads, the same as any site that uses them.

Changes

If this policy changes, we'll update this page and the date at the top.
