Direct answer

Rotate BLE pairing keys after ownership transfer, factory service, or confirmed bond compromise, not on every app login. Provide a reset path that clears bonds on the device and tells the user to forget the peripheral on the phone. For example, a rental sensor should rotate keys when reassigned to a new customer account.
