• Visitor information and tracking I do not use Google Analytics, Piwik or any other form or tracking on this site. My server keeps access logs, which are then analyzed with Awstats. This form of visitor information is relatively anonymous and gives me global visitor counts. Other than my web host, no third parties have access to this information.

• Third party content My site collects content or other sites, that is relevant for specific pages. In all cases, this information was openly available on the internet, and I therefore see it as a citation with source.
