I don&#x27;t work for Facebook or anything, but based on my own judgement I believe they upload the pictures on to their servers to then analyze with their super computing power, which our phones are not capable of yet, without of course analyzing all their existing data within our phones, which I doubt they would give an end user (probably too large of a data set). I&#x27;ve uninstalled the Facebook Apps since a while back, they request for permission to do really strange and intrusive things such as reading all of my SMS text messages, no thanks.
