I use a number of images on this website, for which I have obtained permission.

Reproduction, regardless whether complete or partial, may occur only free of charge to the recipient and prominently carrying a source identifier to enable the recipient to find this website. Any other form of display that obscures the origin of the content, eg. by using frames, is expressly prohibited and may result in legal action. Reproduction on offline material like eg. books or CDs, may occur only after having obtained written permission from me and other relevant authors, if applicable. Recording of this content within the context of search engines is permitted if those search engines prominently display the origin of the content to the user.

Due to the nature of the Internet, no claim pertaining to the authenticity and correctness of the displayed data can be made. I do my best to ensure these, but disclaim any and all liability for material obtained from my servers.

Liability for External Content

As a matter of precaution, I think I need to state the obvious:

  • I strive to make links to foreign websites open in new tabs or windows, so you should not mistakenly believe you were still receiving such content from my website.
  • When I provide a link to a foreign resource, I do this in good faith that the provided link and link target was legal at the time I added the link to my website. Of course, I typically have no control over foreign websites whatsoever, so if the linked-to content may be illegal at some point, or unavailable, that should be well outside my realm of power. If you encounter such a situation and think this must be rectified, please notify me, and I will see what I can do about it. In the worst of events, you should feel free to abstain from viewing content that you deem unsuitable.

Data Protection

This website makes use of cookies in case you are being logged in. Furthermore, I also log visits to this website and use a tool to track web visits to my site in order to optimize the site for my visitors, and to maintain the security of this site. The tracking apparatus is part of my own installation, so at least I don't actively share such data with third parties. If you do not want to be tracked, you are free to block access to my tracking server, but regular logging will be unaffected.

Errors, Mistakes, Omissions

If you find something you do not like, or if you are missing some functionality, please notify me.
Thank you!
