I like this line of questions;  here are some more…

1) Is the data personally-derived, i.e. derived from the interaction of a single person, or their device or address?  [If so, even if anonymous, it might be re-correlated]
2) Does the data record contain elements that would enable such re-correlation?  [examples include an IP address, and so on]
3) What other data could this record be correlated with? [e.g. the ISP]
4) If you had large amounts of this data about one person, what conclusions would it enable you to draw? [e.g. maybe you could estimate location from many ambient light events by estimating latitude and longitude from the times of sunrise and sunset]
