Tucker Carlson gave a staffer several phones that had all had the Internet disabled in one way or another then sent him on a road trip to sites that were supposed to be secured by restricting WiFi or having private access. When the guy got back they put the phones on traffic loggers and restored them to normal use. Every one sent location information straight to Google. They said that even the supposed secure locations could be easily figured out just by looking at the GPS coordinates. All of the phones stored the data until it could be sent when the connection to Google was restored. Creepy stuff.
Oh, my gosh...that IS creepy!
