Open the iPhone Settings app, tap your name, then Subscriptions. Select HueBook to manage or cancel it. Apple manages billing, renewals, cancellations, and refunds.

How do I back up or move my records?

HueBook Pro can prepare a JSON backup from Settings. Choose a secure destination in the system share sheet and handle the exported client data according to your professional and local privacy obligations.
