Tell us the app version, your device and what happened so we can help faster. Never send your password.

Do I need to sign in?: No. All learning, duels on one device and challenge codes work without an account. An account is only for sync, guardian links and friend groups.
How do I unlock my purchase on a new phone?: Tap Settings › Restore purchase while signed in to the store account you bought with (Apple ID or Google account).
How do I open something my family bought with Apple Family Sharing?: Tap Settings › Restore purchase. It opens if you are in the same Apple family and Family Sharing is on.
My child bought it by mistake.: Ask the store for a refund (Terms, section 4). Turning on Apple’s Ask to Buy or Google Play purchase approvals makes future purchases wait for a guardian’s approval.
The guardian consent email did not arrive.: Check the spam folder, then tap “Send the email again” on the waiting screen in the app. Sending too often blocks it for a while.
How do I move my records?: Sign in with an account to sync. Without an account, use Settings › Export backup file and then Import backup file on the new device.
How do I delete my account?: See Delete your account.
