Reset progress or delete everything
GudMem gives you two levels of "start over," both in Settings.
Reset progress. Choose a group and reset its learning history: every face goes back to unlearned and the schedule restarts. Your people, photos, notes and recordings stay. Handy at the start of a new term with the same group.
Delete all data. Erases everything — every group, face, note and recording — from this device. Because there's no cloud copy, this can't be undone. Make a backup first if you might want the data back.
Both actions ask you to confirm before anything is removed.
