I agree it's sensitive, but if you are abiding by the deidentification and definition of tracking, then the data you are keeping cannot be used to identify an individual user, user-agent, or device. Maybe we need a note on the sensitivity of geolocation (in our informative companion material), but by mentioning it explicitly it gives the appearance of different (strangely, laxer) rules for this data. I say laxer because there are very thinly populated postal codes, so the postal code with very little more information CAN identify someone.
