Apple is the manufacturer who makes the biggest hoo-ha over privacy, yet they gave user data to the police 90% of the time (Google was surprisingly lower at 80%)
Plus if you have a subscription to a mobile cellular network, as basically everyone with a phone does, that will also be constantly tracking you (and I believe also directly available to the police).
That's all without going into whether you trust every single third party app on your phone and every website you visit.
