Delete your account and learning records
For the app account created through Google sign-in in Malangsoft’s HanjaFriend Android app and its synchronized learning records. Last updated: November 5, 2026.
Request deletion without the app
You do not need to reinstall the app. Email an account deletion request to indian311@icloud.com ↗.
- Send the request from the Google account email address used to sign in to HanjaFriend. If you contact us from a different address, we may request further account ownership verification.
- Use the subject “HanjaFriend Android account deletion request” and state that you want your HanjaFriend app account and its associated synchronized learning records deleted.
- After verifying account ownership, we will process the deletion and reply with the result. Do not send passwords, verification codes or payment information. A parent or guardian may contact us, but account ownership must still be verified before deletion.
Delete directly in the app
Open the sync settings at the top of the character list → Learning synchronization → Delete account and synchronized records. A recent sign-in is required. If a connection error interrupts deletion, sign in and retry, or email us as described above.
What is deleted
We delete the HanjaFriend Firebase Authentication account and its associated Cloud Firestore learning records: per-character reading and writing attempts, answers, assessment results, learning dates and review information. Deleting in the app also removes that account’s local learning records on that device. Your Google account itself and other apps’ data are not deleted. Deletion cannot be undone.
Retained information and limitations
- A minimal deletion marker containing only the previous Firebase UID and deletion status is retained to prevent delayed uploads from other devices from recreating deleted records. The marker does not contain learning records or email, and it has no fixed automatic expiry.
- An email request does not remotely erase other devices’ offline storage. To remove account-specific local records or pre-sign-in guest records on those devices, clear the app’s data or uninstall it on each device.
- We do not add account emails or user IDs to Crashlytics, so we may be unable to associate existing anonymous diagnostic records with a particular account for deletion. Retention and deletion of diagnostic records and service backups follow Firebase privacy information.
- Support emails used for deletion requests and ownership verification are used to process and confirm the request. They have no configured fixed automatic deletion period; you can also ask us to delete the support correspondence at the same address.
