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 the user-agent string (which identifies the browser) to assist in detecting spam.


From your email address, an anonymous string of characters (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, this may be a consent to store your name, e-mail address and website in cookies. This is a convenience feature so that you don't have to re-enter all this information when you write another comment. These cookies are stored for one year.


If you have an account and log on to this site, we will set a temporary cookie to determine if your browser accepts cookies. This cookie does not contain any personal information and is discarded when you close your browser.


When you log in, we will set some cookies to store your login information and display options. Login cookies expire after two days and display option cookies expire after one year. If you select "Stay signed in" when you sign in, your sign-in will be maintained for two weeks. When you log out of your account, the login cookies are deleted.


When you edit or publish an article, an additional cookie is stored in your browser. This cookie contains no personal data and only refers to the post ID of the article you have just edited. The cookie expires after one day.

Embedded content from other websites

Contributions on this website may contain embedded content (e.g. videos, pictures, articles etc.). Embedded content from other websites behaves exactly as if the visitor had visited the other website.


These sites may collect information about you, use cookies, embed additional third-party tracking services, and record your interaction with that embedded content, including your interaction with the embedded content if you have an account and are logged on to that site.

Data from members
Name, address, date of birth and email address are processed for the purpose of member administration. For the purpose of membership fee administration the bank details are processed. The legal basis for both is Art. 6 Paragraph b) DS-GVO.
How long we store your data

How long we store your data

If you write a comment, it will be saved including metadata for an unlimited time. This way we can automatically detect and release follow-up comments instead of having to keep them in a moderation queue.

For users who register on our website, we also store the personal information they provide in their user profiles. All users can view, change or delete their personal information at any time (the user name cannot be changed). Website administrators can also view and change this information.


The data necessary for the data member administration (such as name, address, date of birth) will be deleted 2 years after the end of the association membership. The data necessary for membership fee administration (bank details) will be deleted after 10 years.
