Open the membership screen and choose Restore purchases. Use the original Apple Account and the correct app account. Trial availability depends on Apple’s eligibility check. Cancel subscriptions in iPhone Settings → Apple Account → Subscriptions; deleting an app account does not cancel billing.
02
Learning records and sign-in
Open Hanzi and Open AtoZ have separate account systems. Sign in using the same method and account you used in that app. Saved progress syncs when a connection is available. A completed review is not automatically a mastered word.
03
Voice and AI
Online voice and AI features need a working connection and may be unavailable during provider interruptions. You can decline microphone access and continue with non-recording features. An active subscription is required for Live; a one-time core purchase does not include it.
04
Delete an account or request data help
In the app, open Settings → Account → Delete account and verify your identity again. This removes the account and associated cloud learning data. Current versions retain isolated local offline data until the app is deleted. For other access, correction or deletion requests, email us and name the app; do not send passwords or payment-card details.
