Pro on a new iPhone or iPad
Open Phrase Piano, tap the gear on Today, then Restore purchases. Pro comes back on any iPhone or iPad signed in to the same Apple Account.
Cancelling Pro
Open your iPhone's Settings, tap your name, then Subscriptions, then Phrase Piano. Cancel at least a day before the free weeks end, or before the plan renews, and nothing more is charged. The app reminds you two days before the free weeks end.
Refunds
Apple handles every payment, so refunds are asked for at reportaproblem.apple.com.
A digital piano on a cable
A cable from your piano's USB port (usually the square USB-B) to your iPhone: USB-C to USB-B for an iPhone 15 or later, or Apple's Lightning to USB Camera Adapter for an earlier one. On a cable the app hears every key, and its part plays through your piano.
Your privacy
The app keeps your progress on your phone and keeps nothing it hears. The whole policy.
