What we store

• Your practice record: per-kanji mastery, mistake counts, when each is next due, and what was served when.
• Account: your email address, or Apple/Google identifier, if you sign in. You can use the app without signing in.
• Settings: daily target, judging settings, timezone.

What we do not store

• Handwriting is never uploaded. Stroke judging happens on your device.
• No advertising trackers. We do not sell or share your data.

Anonymous use

If you start without signing in, progress is tied to that session. Anonymous sessions with no practice are deleted after 24 hours; those with practice are deleted 14 days after the last practice. Signing in is required to continue on another device.

Deletion

You can delete your account from inside the app. Your practice record is deleted with it, and this cannot be undone.

Bug reports

If you report a problem from inside the app, the report is recorded in our internal issue tracker. Your contact details are not recorded in the issue; they are stored separately.

Payment details

We do not receive your card details. Paddle handles payment on the web; Apple handles it in the App Store.
