No OS protects you from this. If you are carrying a device that communicates with cell towers, your location is being triangulated and logged. I’m not sure about the daily location signals they’re referring to, but cell tower triangulation has been a thing for a long while.
Only way to avoid it would be to only carry devices that cannot transmit data. Internetingly enough, pagers fit the bill as receive-only devices. Messages are broadcast on the entire network instead of routed to a single device.
Everyone out here guessing small OEMs for an official Graphene launch when it’s obviously Apple.
