What personal data we collect and why we collect it


When visitors post comments on the site, we collect the information displayed in the comment form, as well as the visitor’s IP address and user agent string (which identifies the browser) to help identify spam.

From your email address, an anonymous string (also called a hash) can be created and passed to the Gravatar service to check if you are using it. You can find the Gravatar service’s privacy policy here: After your comment is posted, your profile picture will be publicly visible in the context of your comment.


If you are a registered user and upload photos to this site, you should avoid uploading photos with an EXIF GPS location. Visitors to this site may download photos stored on this site and extract their location information.


When you write a comment on our website, it may be a consent to store your name, e-mail address and website in cookies. This is a convenience feature so that you do not have to re-enter all this information when you write another comment. These cookies are stored for one year.

Log Files

The server is operated by the company Host Europe GmbH, Hansestrasse 111, 51149 Cologne, Germany. The server log file stores information that your browser sends to the server. These are:

  • Browser type/version
  • Operating system used
  • Referrer URL (the previously visited page)
  • Host name of the accessing computer (IP address)

These data are not assignable for us to specific persons. A consolidation of this data with other data sources is not carried out and the data is deleted after one year.

How long we store your data

When you write a comment, it will be saved indefinitely, including metadata. This way we can automatically detect and release follow-up comments instead of keeping them in a moderation queue.

If you have written comments, you can request an export of your personal data from us, including all the data you have given us. In addition, you can request the deletion of all personal data that we have stored about you. This does not include data that we have to keep due to administrative, legal or security reasons.

Where we send your data to

Visitor comments could be examined by an automated spam detection service.


You have the right to object to the processing of your data. This also applies to parts of your data. You can also object to the consent to this data protection declaration in the future.
