> "Although the data sent to Google is encrypted, it could potentially be sent to a third party if the phone had been compromised with spyware or other methods of hacking. Each phone has a unique ID number, with which the location data can be associated." If the phone is compromised, it doesn't matter what google has access to, the tracking kit can just enable it's own tracking and spoof the system status (depending on the level of the compromise) If you have a concern about your phone tracking you, don't bring your phone with you.
