Personally I can't trust apple for a specific reason... On iOS they've made it quite difficult to turn location services off unless you jailbreak the device itself. You have to go into settings -> privace -> locations -> on - off -> are you sure you want to do it? -> yes ....
I mean when a company does that, it makes it pretty clear that they do want to monitor your location, making it annoying for you to turn it on and off.
