Ouch, I kind of wish you hadn't said that, because it sounds like you're straying dangerously close into weasel words and deliberately incorrectly interpretations. Sorry if that sounds harsh, but what I've read is very clear.

As before I like your solution, and I think it's absolutely in the spirit of privacy. But the guidance is really clear here, and gives examples of fingerprinting. Nobody said a fingerprint has to be a permanent identifier; as far as I recall, Fathom does use fingerprinting to identify individuals, so that a sequence of page views can be attributed to a single visitor. I understand that those fingerprints include a timestamp, and so are only valid for some time (2 hours, or whatever it is).
