For login, practice, MIDI/microphone, synchronization or billing issues, email support@nolab.dev. Include the app version, device model, operating system and steps to reproduce the issue. Do not send passwords, verification codes, payment-card information or private API keys.
Restore a purchase
Use the same store account and PianoSpark account used for the original purchase, then select Restore Purchases on the PRO page. A purchase cannot be transferred to an unrelated PianoSpark account merely by signing in to the same Apple Account. Pending store approval or a temporary server error may require a later retry.
Cancel or request a refund
Manage Apple subscriptions using the link below. On Android use Google Play > Payments & subscriptions. Store support handles refund requests. Deleting your PianoSpark account or uninstalling the app does not automatically cancel a subscription.
Instrument and microphone troubleshooting
Check instrument compatibility, Bluetooth/MIDI connection and microphone permission. Pitch detection requires audible piano notes and a suitable input level. Restart the connection or select a different input mode if needed.
