Do something nice for your family this holiday season: go through their phone settings and turn on all the privacy features.
It’s sort of amazing to me how hard this has gotten, even on iOS, which advertises itself as the “privacy” OS. My wife asked me how Facebook knew she walked by a particular store yesterday, so I dove into the Settings. What a mess.
First, there’s this “Privacy” tab in iOS settings, but under it you’ve got this ridiculous and ever-growing list of crap. Every app appears multiple times, and you have to know where to look. 
Browsing the “Location Services” tab alone is a nightmare. There’s no way to sort by “Always”, which is usually the particularly bad permission you care about. (Although “While Using” is a bit ambiguous too.)
And don’t get me started on this “Bluetooth” tab. Why do any of these apps need direct access to my Bluetooth other than crappy tracking?
And even if you turn off location services for an app, the app may still get this data by examining the metadata from your photos. (I’m not sure if iOS13 fixes this.)
TL;DR If Apple’s going to advertise itself as the “private” phone, they need to do a much better job than this. “At least we’re aren’t Google!” is pretty much the best they can say.
