Privacy policy

Last updated 11 September 2026

What we store on your device

When you save a progression, or simply keep writing, the app stores your chords, chosen shapes, mood, key and genre settings, and timestamps in your browser's local storage. This data never leaves your device. It is not synced to other devices and it disappears if you clear your browser data or use a private window.

Analytics

This version of the app does not send any analytics events. If that changes, this page will list the provider and the events collected.

Cookies

The app sets no cookies. It uses browser storage only for the saved progressions described above and a per-tab flag that prevents duplicate analytics events within one visit.

Third parties

The site is served by a static hosting provider that receives the usual technical request data (IP address, browser type) to deliver the pages. No user content is sent to any third party.

If accounts or paid features arrive

Should we add accounts, cloud sync or payments in the future, we will update this policy before those features launch and explain what changes, what is stored where, and how you can delete it.
