When visitors write comments on the site, we collect the data that appears in the comment form, as well as the visitor’s IP address and the user agent string (which identifies the browser), to help detect spam.

An anonymised string (also called a hash) can be created from your email address and sent to the Gravatar service to check if you use it. You can find the data protection statement of the Gravatar service here: https://automattic.com/privacy/. Once your comment has been validated, your profile picture is 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 the location information.

If you write a comment on our website, it may mean that you agree to have your name, email address and website stored in cookies. This is a convenience feature that saves you from having to re-enter all this data when you write another comment. These cookies are stored for one year.

If you have an account and log in to this site, we will set a temporary cookie to determine whether your browser accepts cookies. This cookie contains no personal data and is destroyed when you close your browser.

If you register, we will set some cookies to remember your login information and display options. Login cookies expire after two days and display option cookies expire after one year. If you select „Stay logged in“ when you register, your registration will be maintained for a fortnight. 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 does not contain any personal data and only refers to the ID of the article you just edited. The cookie expires after one day.
Embedded content from other websites

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

These sites may collect data about you, use cookies, incorporate 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 in to that site.
Who we share your data with

If you request a password reset, your IP address will be included in the reset email.
How long we keep your data

When you write a comment, it, including the metadata, is stored for an unlimited period of time. In this way, we can automatically recognise and validate follow-up comments instead of keeping them in a moderation queue.

For users who register on our site, we also store the personal information they provide in their user profile. All users can view, edit or delete their personal information at any time (the username cannot be changed). Site administrators can also view and change this information.
What rights do you have over your data?

If you have an account on this site or if you have written comments, you can ask us to export your personal data, including all the data you have given us. In addition, you can request the deletion of any personal data we hold about you. This does not include data that we need to retain for administrative, legal or security purposes.
Where we send your data

Visitors‘ comments may be reviewed by an automated spam detection service.
