Specifically Google Location History...
All good and well using a punting phone, but I still take my main phone with me. Is this a mistake? Should I leave it somewhere? ?
I noticed that if you have a google account (mandatory for many android phones), google is constantly keeping dabs on you. Although the app doesn't share you location per se, if you go to google and type in 'location history' and log in...ALL your movements for the the last wee while is clearly displayed with timestamps and all.
If your OH knows your email password, it's quite easy to effectively track you. Even scarier, if you've switched location history off, it's fairly easy via the console to enable it or re-enable it.
OK, the latter scenario is unlikely, but not impossible. Beware folks
