Progress and local data
Piano Lantern stores progress on your device. In Settings, “Reset learning progress” clears story and music progress and review suggestions while retaining check history and purchase ownership. To remove saved progress, settings and reading history, select “Delete progress and settings” and confirm. A setup marker and, on Android, cached purchase verification evidence may remain. Separate device backups are not removed by this action.
