Review privacy and deletion detailsQuestions
Why is the full performance not available?
Free listening has a daily on-device limit. A Member subscription removes that daily playback limit while the subscription is active.
How do I stop renewal?
Manage or cancel renewal through your Apple account subscription settings. Deleting NoteLight does not cancel an active subscription.
Why did Restore Purchases find nothing?
Confirm that the device uses the Apple account that made the purchase and try again with a network connection. Apple controls purchase records and refund decisions.
Where are Favorites and settings stored?
The current product design keeps Favorites, playback preferences, and the daily free-play meter on the device.
Can NoteLight teach me to play piano?
NoteLight is designed as a visual piano listening experience. It does not provide lessons, performance scoring, or a learning guarantee.
How do I request access to or deletion of data?
Use Delete Account in NoteLight to remove product data, or email support@591master.com for help with an access or deletion request. Data deletion does not cancel an Apple subscription.
