Yes, it is private by technology:
GPS and other systems working the same way are passive, similar to receiving a radio signal. You’re receiving the signal of several satellites at the same time and your device calculates your position based on those signals. You’re basically getting “I’m satellite cool boy and at the next beep it’s exactly five past nine” all the time - only with a bit more precision. Your device does rhen the actusl position calculation locally.
Fun fact! Geo positioning is one off the few things where we need to apply both general and special relativity for real world effects: the effects due to the satellites speed and high distance to earth (and therefore the reduced effect of gravity) cause a significant shift in the speed in which clocks run on those satellites compare to Earth. As we use the exact time to calculate distance and with that position this would cause a huge drift otherwise!










I don’t think it’ll come globally at all - even the most crazy laws I’ve read so far target “only” OS vendors.
If it comes it’ll be regional only as manufacturers will be hell bent on not losing revenue in the rest of the world.
Keep in mind that age verification needs to be done on a local level as there is no universal level of what is an acceptable method.
