Nothing leaves your phone.
Alarms, missions and your wake history are stored on your phone. There is no account and no server that holds a copy.
The voice and face missions run on the phone. No audio and no image is uploaded, saved, or sent anywhere.
Apple Music plays through Apple's own player, and your Apple Music account stays between you and Apple. A podcast or a radio station is fetched from its own publisher, the same as any player.
No analytics, no advertising identifiers, no location, no contact list. Purchases go through Apple, so we never see your card.
