Reproduction, editing, distribution as well as the use of any kind outside the scope of the copyright law require a written permission of the author or originator. Downloads and copies of these websites are permitted for private use only. The commercial use of our contents without permission of the originator is prohibited.

Copyright laws of third parties are respected as long as the contents on these websites do not originate from the provider. Contributions of third parties on this site are indicated as such. However, if you notice any violations of copyright law, please inform us. Such contents will be removed immediately.

IBM, Nikon, LBS, Vodafone, Audi, Lego, Volkswagen, Mercedes-Benz, Porsche, TRW and other company names are protected tradmarks of the respective companies.


As service providers, we are liable for own contents of these websites according to Sec. 7, paragraph 1 German Telemedia Act (TMG). However, according to Sec. 8 to 10 German Telemedia Act (TMG), service providers are not obligated to permanently monitor submitted or stored information or to search for evidences that indicate illegal activities. Legal obligations to removing information or to blocking the use of information remain unchallenged. In this case, liability is only possible at the time of knowledge about a specific violation of law. Illegal contents will be removed immediately at the time we get knowledge of them.


Our offer includes links to external third party websites. We have no influence on the contents of those websites, therefore we cannot guarantee for those contents. Providers or administrators of linked websites are always responsible for their own contents. The linked websites had been checked for possible violations of law at the time of the establishment of the link. Illegal contents were not detected at the time of the linking. A permanent monitoring of the contents of linked websites cannot be imposed without reasonable indications that there has been a violation of law. Illegal links will be removed immediately at the time we get knowledge of them.

Cookies, Web-Analysis, Privacy

We want to know what people think of our website, and which projects attract most interest. That’s why we use Matomo (formerly Piwik) (, a web analysis service that tries to store cookies on your computer – but only if you give us permission.

Cookies are little text files that store information such as whether someone has visited our website before (and if so, when). Whenever you request a madhat web page, our web server retrieves the information stored in the cookie. This, together with the IP address tells us roughly where our visitors are coming from.

It does not tell us who you are, or what else you do on the Internet. All it provides is a rough, anonymized analysis that gives us an idea of how our web service is being used.

For example: "In May, XXX people from Hamburg viewed project YYY on our website. Of those, XXX had visited our website before and XXX were first-time visitors.“ That could interest us if project YYY had featured in the media during that period, for instance. We store this kind of information for internal evaluation. We do not pass information on to third parties.

So your personal privacy is still assured even if you agree to help us improve our web offering. If you refuse cookies, then obviously none will be stored. As you probably know, you can use your browser’s configuration settings to refuse all cookies (or delete accepted cookies regularly).

If you have any questions, please don’t hesitate to get in touch. Our contact data are at the top of this page.
