Privacy policy

What we store

Hanzilla stores the minimum needed to sync your learning: your account identifier (an email address if you create an account; an anonymous identifier if you continue as a guest), your learning progress — which cards you answered, when and how — and your settings, such as daily goals and writing strictness.

What we don't do

• No advertising and no advertising identifiers.
• No sale or sharing of personal data with third parties.
• No tracking outside the app.

Handwriting

Strokes you draw are evaluated on your device. What reaches the server is the result of an exercise (correct or not), which drives your review schedule — not a recording of your handwriting.

Guest accounts

You can use Hanzilla without an email. A guest account is a full account tied to an anonymous identifier; if you later add an email, your progress carries over.

Deleting your data

You can delete your account and all associated data from the app's profile screen, or by writing to support@hanzilla.app.
