I hate those websites which collect all they can about you and your cat, so don't worry, I'll not do that in this website.
All the assets needed to view this website are stored on servers I manage, without relying on third parties to send them. This means no styles or scripts are loaded from public CDNs, so they can't see your navigation activity.
There are no navigation trackers (such as Google Analytics or Piwiki) active on this website, and neither things like social buttons which sends every page you visit to their social network. This also means, the Do Not Track header is ignored because there is no tracking in the first place!
The webserver which serves this requests collects basic information about the navigation (IP address, visited page, user agent and date). Those information are stored for a month in order to be able to resolve issues or investigate malicious traffic. Those information might be also present in the servers' backups.
The servers which powers this website are hosted with DigitalOcean (an US company) in Frankfurt (Germany). You can check out their security practices. Also, the connection between you and the servers is encrypted with TSL, with no third parties in the middle such as CloudFlare.
If you have any other question please contact me!
