All your data is on your device only. Delete the app to remove it all.
If you have an account
In the app: More → My account → Delete account, then confirm with your authenticator code.
Without the app: email us from your registered address (email button below) with the subject "Delete my account"; we verify ownership first.
What is deleted
Email, two-step secret, khatmah plans, bookmarks, synced settings and reading history. Sessions are revoked immediately; the account is permanently deleted after 14 days and cannot be undone once confirmed. Backups expire within 35 days and the deletion is re-applied if one is restored.
