Please be aware that data transfer via the internet is subject to security risks and, therefore, complete protection against third-party access to transferred data cannot be ensured.
Our website makes use of so-called cookies in order to recognize repeat use of our website by the same user/internet connection subscriber. Cookies are small text files that your internet browser downloads and stores on your computer. They are used to improve our website and services. In most cases these are so-called "session cookies" that are deleted once you leave our website.
To an extent, however, these cookies also pass along information used to automatically recognize you. Recognition occurs through an IP address saved to the cookies. The information thereby obtained is used to improve our services and to expedite your access to the website.
You can prevent cookies from being installed by adjusting the settings on your browser software accordingly. You should be aware, however, that by doing so you may not be able to make full use of all the functions of our website.
For technical reasons, data such as the following, which your internet browser transmits to us or to our web space provider (so called server log files), is collected: - type and version of the browser you use - operating system - websites that linked you to our site (referrer URL) - websites that you visit - date and time of your visit - your Internet Protocol (IP) address. This anonymous data is stored separately from any personal information you may have provided, thereby making it impossible to connect it to any particular person. The data is used for statistical purposes in order to improve our website and services.
Our website offers you the opportunity to subscribe to our newsletter. The newsletter provides you periodically with information about our services. To receive our newsletter, we require a valid email address. We will review the email address you provide for the purpose of determining whether you are in fact the owner of the email address provided or whether the actual owner of said address is authorized to receive the newsletter. When subscribing to our newsletter, we will store your IP address as well as the date and time you subscribed. This serves to protect us in the event a third party improperly and without your knowledge makes use of your email address to subscribe to our newsletter. We will not collect any other data. The data thereby collected is used solely for the purpose of receiving our newsletter. No data is transferred to third parties. Nor is any of this information matched to any information that other components of our website may collect. You may cancel your subscription to the newsletter at any time. You will find additional details in the email confirming your subscription as well as in each newsletter.
On our website we offer you the opportunity to contact us, either by email and/or by using a contact form.

On our website we promote a project by c't, called "Shariff". "Shariff" replaces the typical share-buttons of social networks and thereby protects surfing behavior.
"Shariff" integrates the share buttons of social networks on our website as a graphic containing a link to the appropriate social network. By clicking on the appropriate icon you will be redirected to the services of your network. The Shariff button provides direct contact between the social network and our users only when the visitor actively clicks the 'Share' button. Only then will your data be transferred to the respective social network. If, however, the Shariff button is not clicked, no exchange will be made between you and the social network. For more information about the c't project "Shariff" visit
We integrate the following social networks on our website with "Shariff":
Facebook, Twitter, Google+, LinkedIn, Xing
