Like I said, I'm fine with the finger prints to be stored locally on "my" phone, just not on a server.
On holiday in May I found a lost iPhone which I handed into the police, in the hope it reached the owner , given its in lost mode, if my fingers made contact with the home button, it would be BS for my details or pics to be uploaded to a server as a would be thief....
Let's be honest , police don't have resources to chase up those individual leads for a smartphone, chances of getting ur phone back would be very very very minimum at best, while people's details would be stored.....until proven innocent . So little benefit for so much privacy given away in return.
