Why does myPhonak request location access while using the app and in background?

myPhonak requests location access while using app in background

myPhonak never stores or uses information about the user's location; the permission is needed by the OS of the phone to be able to optimize background synchronization with the hearing aid.
myPhonak synchronizes the data and time with the hearing aids several times throughout the day. Hearing aids are designed to save energy whenever possible, therefore, they rely on the app to synchronize time at least once per day.
