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 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.
