Delete it yourself
Open your Settings, go to the Account tab, and choose Delete Account. You will be asked to confirm because the action cannot be undone. All data tied to that account is permanently removed. See deleting your account for the full walkthrough.
Ask us to erase your data
If you signed in with a username and cannot use settings, or you want a record removed for another reason, contact us through the Help Center and we will handle the deletion request.
What happens to your progress
Deleting your account also removes your saved lessons, stats, and streaks, so export or note anything you want to keep first. To understand what we held in the first place, read our data and privacy overview.
