Liability for links

We can accept no liability for links to third party sites. At the point of creation we checked that they didn't break laws, but permanent checking is not possible. In case one of those external links breaks laws, we will remove them as soon as we are notified of that.


The use of this website can be done without supplying personal information for the most part. Where we collect personally identifiable information(for example name, email, address) it is supplied voluntarily. This data will not be shared with third parties without your explicit concent.

We are using Matomo to track the website usage to improve the user experience. The IP address is analysed during this tracking.

Data transfer across the internet(for example via email) can have security issues.
It is therefore not possible to guarantee a complete data protection from third party access.

The use of contact data provided because of the imprint requirement for other purposes, like sending advertisements and information mails, is not acceptable.
We reserve the right to combat abuse of the contact data legally in cases of abuse, for example spam mails.
