do note that while your location MAY not be shared, the absence of location information for when you turn on airplane mode reveals at least when you left and returned to the house.
i was worried also that airplane mode may not actually disable the radio but at least one random google result (from reddit, not graphene themselves) says it does.

Sure, the neighbors' cloud-connected doorcams reveal that too. Although I do enable airplane mode here and there while I'm still at my house whenever I don't want to be disturbed for a couple of hours, and I don't always remember to disable airplane mode the instant I walk through my front door, so that's not terribly clean signal for "he left the house at this time and returned at that."
