Android app sideloading utilized something called a “privacy budget,” where the system does give sandboxed apps access to “limited” device data. The idea is that Google “doesn’t want to break the app functionality,” so Android provides details about the device as long as the app isn’t requesting “too much.”

Of course it’s possible to to completely sandbox an app without breaking it, but, again, Google is an adtech company and providing their customers with users that they can target with ads is literally their only goal.

I stopped reading your reply after your first paragraph because you’ve established a very predictable pattern of having no idea what you’re talking about.
