Forget the government, it’s your phone apps that are chronically spying on you.
I got addicted to Clicker Heroes recently, which is one of those idle-/tapRPG games. I played it for about a week when I noticed my phone was absolutely destroying my data allowance.1 So I reset the “what apps have been using my data?” tab, let the phone run for a bit, came back to it and by far the biggest consumer of my 4G data? Clicker Heroes.
Uh. How ’bout no? I’ve got no idea why an offline game should be chattier over the internet than, say, Tumblr, but I don’t like it. So that got its internet access disabled.
Thankfully, it still worked afterwards.2 The last app I went through something similar with, Kim Kardashian: Hollywoood, didn’t. Which, incidentally, is why I no longer play Kim Kardashian: Hollywood.
