Data Privacy

The operators of this site take the protection of your personal data very seriously. We handle your personal data in confidence and in accordance with statutory data protection provisions and this Data Privacy Statement.

As a rule it is possible to use our website without giving any personal details. If personal data (for instance, name, address or e-mail addresses) are collected, this is always done, insofar as possible, on a voluntary basis. Unless we have your express agreement these data are not passed to third parties.

We draw your attention to the fact that data transfer on the Internet (e.g. in communication by e-mail) may not be totally secure. It is not completely possible to protect data from access by third parties.


To some extent the websites use what are known as cookies. Cookies cause no harm to your browser and contain no viruses. Cookies serve to allow us to make our offer more user-friendly, more effective and more secure. Cookies are small text files, which are deposited on your computer and saved by your browser.

Most of the cookies used by us are session cookies. These are automatically erased when you leave our website. Other cookies remain stored on your device until you erase them. These cookies allow us to recognise your browser the next time you visit us.

You can adjust the settings on your browser so that you are notified of the installation of cookies and may permit cookies only in individual cases, refuse to accept cookies for specified cases or exclude them generally and activate automatic deletion of cookies when you close your browser. We would advise you that deactivating cookies may restrict the functionality of this website.

Contact form

If you send us enquiries via our contact form, we store the data you have entered on the enquiry form, including the contact data supplied by you on the form for the purpose of processing the enquiry and in case there are follow-up enquiries. We do not pass on these data without your consent.

Information, erasure, blocking
You have the right at any time to information, free of charge, concerning your stored data, their origin and recipient and the purpose for which they are processed, as well as a right to rectification, blocking or erasure of these data. For this purpose and if you have any other questions about personal data, you may contact us at any time through the address stated in the legal notice.

Repudiation of advertising e-mails

The use of contact data published under our duty to provide a legal notice for the transmission of advertising and information materials, which have not been expressly requested, is hereby repudiated. The site operators expressly reserve the right to take legal steps in the case of the unsolicited sending of advertising information, such as through spam e-mails.

Data Privacy Statement for the use of Google Analytics

On our site we use Google-Analytics, a web analysis service from Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043 USA, hereinafter Google. Google Analytics uses text files, known as cookies, which are stored on your computer and allow the use of the website to be analysed. 
The information generated by these cookies, for example, the time, place and frequency of your visits to our website including your IP address, is transferred to Google in the USA and stored there.
On our site we use Google-Analytics with the suffix “_gat._anonymizeIp”. This means that your IP address is abbreviated by Google within the Member States of the European Union or in other Signatory States to the Agreement on the European Economic Area and thus anonymised.
Google shall use this information in order to evaluate your use of the website, to compile reports on website activities for the website operator and to perform other services connected with the use of the website and the use of the Internet. In addition, Google shall forward this information to third parties, insofar as this is required by law or insofar as third parties process these data on behalf of Google.

Google informs us that on no account will it link your IP address with any other data from Google. You can prevent your computer storing cookies by adjusting the settings of your browser software; however, we should like to make you aware that in this case you may not be able to use all the functions of this website to their full extent. 
Furthermore, for the most popular browsers Google offers a deactivation add-on; which gives you more control over which data are collected by Google from the websites you have accessed. The add-on informs the Google Analytics JavaScript (ga.js) that no information on the visit to a website should be transferred to Google Analytics. However, the deactivation add-on from Google Analytics does not prevent information being transferred to us or to any other web analysis services, which we have employed. Further information on installing the browser add-on is available via the following link:

Data Privacy Statement for the use of YouTube

Our website uses plug-ins from the YouTube site operated by Google. The service provider is YouTube LLC, 901 Cherry Avenue, San Bruno, CA 94066, USA. If you visit one of our pages fitted with a YouTube plug-in, a connection is made to the YouTube servers. In this way the YouTube server is informed which pages of our website you have visited.

If you are logged in to your YouTube account, you are allowing YouTube to allocate your surfing behaviour directly to your personal profile. You can prevent this by logging out of your YouTube account.

Other information on how user data are treated is available in the YouTube Data Privacy Statement on


Plug-ins from the social network Facebook, 1601 South California Avenue, Palo Alto, CA 94304, USA, are integrated into our website pages. You can recognise the Facebook plug-ins by the Facebook logo or the Like button on our site. An overview of Facebook plug-ins is available here: When you visit our site the plug-in sets up a direct link between your browser and the Facebook server. This informs Facebook that you, with your IP address, have visited our site. If you click on the Facebook Like button while you are logged in to your Facebook account, you can link the contents of our site to your Facebook profile. This allows Facebook to allocate your visit to our site to your user account. We advise you that we as the access provider for our site have no knowledge of the content of the data transferred or of their use by Facebook.

Facebook, Google Plus, Instagram, Linkedin, Pinterest, Twitter and XING

On many of its pages our website has buttons to sharethe site contents on the social media platforms, Facebook, Google Plus, Instagram, Linkedin, Pinterest, Twitter and XING.
Within the meaning of the protection of our website visitors’ personal data the buttons are ideally designed, since the script (computer program) underlying the buttons does not collect or process any personal data. Exact information on how the buttons work is available from Heise Verlag, the publisher of the c’t IT specialist magazine and the developer of the buttons.
When visitors to our website, who wish to share our website, click on the buttons they are directed straight to the “Share” sites of the respective social media platforms. It is not until arrival on that site that scripts required to share the website contents are loaded. From that point the Terms and Conditions of Business and Data Protection Conditions agreed by the website visitor with the respective social media platform apply. The respective Facebook, Google Plus, Instagram, Linkedin, Pinterest, Twitter and XING platforms provide detailed information on this.

Server Log Files

The website provider automatically collects and stores data in what are known as server log files, which your browser automatically transfers to us. These are:
• browser type and browser version
• operating system used

Publication of employment vacancy advertisements / online job applications

In order to manage the application procedure we collect and electronically process your application data. If your application results in the conclusion of an employment contract, we may store the information, which you have provided to us, in your personal file for the purposes of the usual organisational and administration procedures, with due regard to the relevant statutory provisions. If your application for employment is not successful, we automatically erase the data you transferred to us two months after notifying you that your application has been unsuccessful. This does not apply, if by virtue of statutory requirements (for example the burden of proof in accordance with the German General Act on Equal Treatment) it is necessary to store the data for a longer period or if you have expressly agreed that we may store your data for a longer period in our database of potential candidates.
