    Go to this page over a cellular connection. (Turn off your wifi) http://checkyourinfo.com/request http://checkyourinfo.com/request Then look for a long number.

  Just checked my phone and I have "do not track" turned on and x-acr is tracking. Who/what is it? Why? How do I stop it?

  Checked over data not WiFi
