What's stored about you

Account: your name, your email and which invite code you used.

Training: every round you play — which chord, how fast, which mistakes — plus stars, milestones and settings. Used for statistics and suggestions.

The administrator sees usage per person: when you last played, number of sessions and rounds, and which stage you're on. Not your individual rounds.

AI suggestions: the explanation for practice suggestions is written by a language model. It only gets chord statistics, never your name or email.

Feedback. When you send feedback or an error report, your text is saved together with page, course, stage, song, language, device type, browser, app version and whether MIDI was connected (and the device name). Error reports also include the error message and your last 20 events in the app (page changes, taps, MIDI). Answers to the difficulty question are saved with the round's accuracy and time. No played notes are saved in feedback. Only the administrator reads it.

Under Settings you can export all your data or delete your account. A deleted account is removed entirely.
