Report a problem

Say what you did, what you expected and what happened. A screenshot helps.

If the problem is about stroke recognition or a study session, the diagnostics log helps most. In the app, open Settings › Diagnostics Log, tap Share Log, choose Mail and send it to support@yubigaki.com. The privacy policy says what the log contains. It has no name, account, location or contacts.
