Get in touch

Email support@valentree.com. Tell us what happened, which screen you were using, and your device and app version if you know them. A screenshot can help; leave out passwords and other private information.

Course progress and backups

The course works offline without an account. In Saved progress, copy your progress backup into a file or note you keep. Paste that backup into Restore progress when you need it. Your device's operating-system backups may also include app data, depending on your settings. We cannot recover course progress from our app servers because the app does not upload it there.

Battle accounts

Online battles require an internet connection and a separate username and password. If sign-in fails, check your username and password and try again. Account usernames use 3–20 letters, numbers or underscores. We do not collect an email address for account creation, so there is no automatic email-based password recovery. If you have forgotten your credentials, contact us; help with an account or deletion request may require verification of ownership. Never email your password.

Delete a battle account

Open Battle → Account → Delete battle account in the app, or use the account-deletion page on our public support website. Sign in and confirm to remove your battle account and related live service data. Your local course progress stays on your device. Limited deletion-security records, backups and operational records may remain as described in the privacy policy.

If you cannot access your account, email support@valentree.com to request deletion assistance.

Piano sound

Check the app's Sound setting and your device's media volume. The course uses recorded piano sounds and does not need microphone permission. It cannot assess the sound or technique of a real piano performance.
