Germany adopted the Apple/Google framework, which is exactly what an Apple/Google app would use. The whole point of the design is that it’s decentralized and you wouldn’t be giving Apple/Google more information.

True. Except that the German app turns on EVERYTHING - LTE, WiFi, Bluetooth, GPS. And the carrier gets it all. I had the app installed for all of maybe 2 minutes because it did exactly what it claimed to do, but I'm not giving the carrier even more granular location info. The only thing I leave on when I leave the house is mobile data.

I'm not in Germany and I don't have compatible phone. But from all I have read the claim about turning on GPS is plain wrong.

German android user here. This is absolutely wrong. I suspect you are misinterpreting the permission message on Android. The app does not turn anything on. I suggest you to learn how androids permission system works before throwing out wrong accusions.

I stand by my post.

Since the contract tracing api doesn’t give information to Apple or Google, it’s hard to see what relevance this comment has.

So they’d have to just force it then?

Or do it like Germany, no centralized info store.

The German approach doesn't give your information to a German centralized info store, but apparently it does require agreeing to feed your location data to Google's own databases on Android devices: https://www.nytimes.com/2020/07/20/technology/google-covid-t...
