I collect, via a Wix.com Web Stat application, the Internet protocol (IP) address used to connect your computer to the Internet. I may use this software tool to measure and collect session information, page response times, length of visits to certain pages, page interaction information, and methods used to browse away from the page. It also indicates which countries website readers reside in. This gives me aggregated statistical data of a non-personal nature to indicate popularity or otherwise of certain posts or to indicate effectiveness of book-marketing copy and access to on line sales outlets on the website.
Should you object to my seeing your IP address then of course, VPN software is an option.
