>"Anonymized". Just with the data posted above, it seems like it'd be pretty easy to correlate the data to a person.

Yep. Location at 3am tells you where they live, and you're basically done already.

That is a correct logical conclusion if you start with the assumption that the data shared with David Pogue included all the data Fitbit has. But maybe you shouldn't start with that assumption.

Disclaimer: I work for Fitbit, but don't speak for Fitbit.

EDIT: Actually there's an additional assumption here, one which I also make, that any app with location permissions has all my GPS location data. But that assumption may be false here. It sounds like where I'm sleeping at 3am isn't recorded according to https://help.fitbit.com/articles/en_US/Help_article/2134
