@brahms What you're not understanding is that nobody you face with those glasses on has any basis for knowing or trusting whether there's a claim that they don't store or send anything. All they see is a camera pointed at them.
Even if they did, you could still be doing plenty of harm without storing or sending anything. You could for example be a running a local model trying to identify them.
Assuring people that this is not happening is not possible but should not be the point. The point is that if someone doesn't want you pointing a camera at them, you don't point a camera at them.
And until you find out, you don't point it at them.
