Delete Account and Data

This page explains how to request deletion of your account and data in the Hanziro application, published by Hanziro.

How to Submit a Request

Send an email to support@hanziro.com with the subject "Delete account".

• If you have linked an email in the App: send the request from that exact email address.
• If you have not linked an email: we will reply with instructions on how to verify that you are the account owner. Do not send your recovery code by email.

We will confirm receipt of your request within 48 business hours and complete the deletion within 30 days.

Data That Is Deleted

• Installation identifier, recovery code hash, and linked email.
• All learning progress: completed lessons, results, words due for review, XP, gems, and study streak.
• All sign-in sessions — the App on any devices currently using the account will be signed out.

Data That May Be Retained

• Security logs (IP address and user agent from sign-in events) may be retained for up to 90 days to prevent abuse, after which they are deleted.
• System backups are overwritten on a rolling cycle; deleted data will disappear from backups within 90 days.

Deletion cannot be undone. Once deleted, your old recovery code and email can no longer restore your progress.

Only Want to Delete Data on Your Device?

Uninstalling the App will delete the data on your device, but will not delete the data on our servers. To delete it permanently, please submit a request as described above.
