This website uses Google Analytics and Gravitar. While some of these companies may let you opt-out of their tracking mechanisms I would recommend downloading and installing Ghostery if you want to effectively prevent this website, or others, from using these systems to track your online behaviour.
Gravitar is a service that is operated by Automattic, Inc., the developers of WordPress. The service provide an image that follows subscribers from site to site, such as when you comment on a post or blog. The company collects the following anonymous data: browser information, date and time, demographic data, and domains images are served to. It also collects pseudonymous information, which includes IP addresses. The company does not share data with third parties. No information is available about the service’s data retention periods.
In addition to Google Analytics and Gravitar, your email address is potentially collected when you leave a comment (dependent on whether you provide a ‘real’ address) and when you use the contact form. The website operator will not make your email available to any third-party, nor will they provide IP address information unless compelled by law enforcement.
