In order to estimate the amount of visitors and downloads, and to check the incoming and outgoing links, Piwik is used to track your activity on this site. The collected data is private and is not shared with third parties. A summary of the data (e.g. the total amount of visitors or downloads over a certain period) may however be made publicly available.
Piwik respects the Do Not Track header. When your browser is set to send this DNT header then your information will not be stored.
However, because the site is open-source and hosted on Github Pages, you can follow all changes on github.
