A lot of great comments here. I just wanted to add that even just your ip address is enough to roughly track your location. When your phone checks gmail you are leaving digital breadcrumbs in Google’s logs of your ip address which roughly tracks your location. App permissions will not solve this. We need strong privacy regulations with teeth.
And then there’s wifi triangulation and Bluetooth which narrows it down further
And this is why my GPS and Bluetooth are disabled 99% of the time unless I’m actually using them. It cuts down on a lot of potential data leakage.
Can’t they just triangulate you from cell towers?
Take the battery out I guess?
