We derive an approximate location (city, region and country) from the IP address by a lookup performed on our own servers; the IP address is not transmitted to a third-party location service. Where you are signed in, the visit record is associated with your Account. Our hosting providers additionally maintain standard server logs, which include IP addresses. Visit records and log data are used for the purposes set out in Section 3.1(c) and (d).
