Yeah it's public so nothing to leak, it's meant to be like this, same in Estonia, your address is public, your name, your birthdate, +/- your face picture, all the land you possess, you can interrogate who is the owner of a specific car plate without any restrictions, see a map of all the traffic accidents with precise information (date, why, what, what was damaged). Then you have semi-public data like phone location (you just need to sign NDA), and guess what ? Everything is fine.

> Is it not is already publicly known? Don’t think there’s anything to leak

The purchases made by an individual, already public? That on that day you were in that place? That you read "The Lance" instead of "The Spear", that you read Comte instead of Hegel?
