Our website may be used without entering personal information. Different rules may apply to certain services on our site, however, and are explained separately below. We collect personal information from you (e.g. name, address, email address, telephone number, etc.) in accordance with the provisions of German data protection statutes. Information is considered personal if it can be associated exclusively to a specific natural person. The legal framework for data protection may be found in the German Federal Data Protection Act (BDSG) and the Telemedia Act (TMG). The provisions below serve to provide information as to the manner, extent and purpose for collecting, using and processing personal information by the provider.

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.
For technical reasons, the following data sent by your internet browser to us or to our server provider will be collected, especially to ensure a secure and stable website: These server log files record the type and version of your browser, operating system, the website from which you came (referrer URL), the webpages on our site visited, the date and time of your visit, as well as the IP address from which you visited our site.
The data thus collected will be temporarily stored, but not in association with any other of your data.
The basis for this storage is Art. 6 Para. 1 lit. f) GDPR. Our legitimate interest lies in the improvement, stability, functionality, and security of our website.
The data will be deleted within no more than seven days, unless continued storage is required for evidentiary purposes. In which case, all or part of the data will be excluded from deletion until the investigation of the relevant incident is finally resolved.
a) Session cookies
This processing makes our website more user-friendly, efficient, and secure, allowing us, for example, to display our website in different languages or to offer a shopping cart function.
The legal basis for such processing is Art. 6 Para. 1 lit. b) GDPR, insofar as these cookies are used to collect data to initiate or process contractual relationships.
If the processing does not serve to initiate or process a contract, our legitimate interest lies in improving the functionality of our website. The legal basis is then Art. 6 Para. 1 lit. f) GDPR.
When you close your browser, these session cookies are deleted.
B) Disabling cookies
If you prevent or restrict the installation of cookies, not all of the functions on our site may be fully usable.
Matomo (formerly: PIWIK)
Our website uses Matomo (formerly: PIWIK). This is open-source software with which we can analyze the use of our site. Data such as your IP address, the pages you visit, the website from which you came (referrer URL), the duration of your visit, and the frequency of your visits is processed.
Matomo stores a cookie on your device via your browser in order to collect this data. This cookie is valid for one week.
The legal basis is Art. 6 Para. 1 lit. f) GDPR. Our legitimate interest lies in the analysis and optimization of our website.
We use Matomo with the “Automatically Anonymize Visitor IPs” function. This anonymization function truncates your IP address by two bytes so that it is impossible to assign it to you or to the internet connection you are using.
If you do not agree to this processing, you have the option of preventing the installation of cookies by making the appropriate settings in your browser. Further details can be found in the section about cookies above.
In addition, you have the option of terminating the analysis of your usage behavior by opting out. By confirming the link
a cookie is stored on your device via your browser to prevent any further analysis. Please note, however, that you must click the above link again if you delete the cookies stored on your end device.
On our website we offer you the opportunity to contact us, either by email and/or by using a contact form. In such event, information provided by the user is stored for the purpose of facilitating communications with the user. No data is transferred to third parties. Nor is any of this information matched to any information that may be collected by other components of our website.
Use of Vimeo components
We use Vimeo components on our site. Vimeo is a service of Vimeo LCC, 555 West 18th Street, New York, New York 10011, USA. Whenever you visit our website, which is equipped with such a component, this component causes the browser you are using to download a corresponding display of the Vimeo component. When you visit our site and are at the same time logged into Vimeo, Vimeo recognizes by means of the information collected by the component, which specific page you are visiting and assigns this information to your personal account at Vimeo. If, for example, you click on the “Play” button or make comments, this information will be conveyed to your personal user account at Vimeo and stored there. In addition, the information that you have visited our site will be passed on to Vimeo. This is done regardless of whether you click on the component/comment or not.
The use of social media buttons with “Shariff”
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 http://www.heise.de/ct/artikel/Shariff-Social-Media-Buttons-mit-Datenschutz-2467514.html
We integrate the following social networks on our website with “Shariff”: Pinterest, Twiter, Facebook, Google+, Flattr
Use of the Amazon Partner program
On the basis of the Federal Data Protection Act, you may contact us at no cost if you have questions relating to the collection, processing or use of your personal information, if you wish to request the correction, blocking or deletion of the same, or if you wish to cancel explicitly granted consent. Please note that you have the right to have incorrect data corrected or to have personal data deleted, where such claim is not barred by any legal obligation to retain this data.
