From what I understand from the conference is that facial recognition is done locally on device and not transmitted. They said that quite clearly. There is probably some specifics I'm missing though, and it raises the question about how they identify others faces. I've not used the feature so I can't say. I'm guessing it's a manual tagging when the device can't find a match and then on device processing afterwards once the algorithm has learned.
