It's very difficult to "stay private" in the age of the Internet and social media.
Even though I pretty much only use my phone for actual phone calls (which are very few) and occasional photos, I'm sure all sorts of stuff is collected. Much of the time, I don't even have my phone on me... it sits face down in a desk drawer till I actually need it for something.
But then I'm older and pre-date the pervasive need to "be connected, 24/7."
I'm older too, but have two phones and a laptop surrounding me & frequently in use, except when I'm asleep or gardening!
