Account & Data Deletion
You can request deletion of your Happy Hanzi account and its associated data in either of the following ways.
Delete from within the app
Go to Settings → Account → “Delete account.” (Requires an app version that supports this feature.)
If you can’t use the app (uninstalled, lost device, etc.)
Email support@qqnana.com from the email address you used to sign in, with the subject “Account deletion request.” After we verify you are the account holder (parent/guardian), we will delete the account within 30 days of the request.
Data that is deleted
- Account information (including the linked Google / Apple account identifier)
- Your child’s profile and learning progress/history
- App settings
Data that is retained
- Purchase and transaction records may be retained for up to 7 years as required by law (tax law, the Act on Specified Commercial Transactions, etc.), and are deleted after that period.
Note: To cancel a subscription, use the subscription settings in Google Play. Deleting your account does not cancel billing automatically.
