I feel it’s a bit of a stretch to compare public information (what city does best guess say an IP is located in) and private information (where is my device right now).

The lookup against what IP is in what city is published in numerous public databases that anyone can look up against in small doses at no cost, or at scale commercially.

This service shines a light on that, doing away with illusions of privacy and showing you where you potentially have none.

Comparing to Google and Facebook feels disingenuous. You can’t lookup any person in their DB and see their records. It’s not public precisely because they’re hoarding what (in aggregate) is legitimately private data.

It’s still an illusion of privacy mind, as all the recent fuss finally coming about demonstrates.
