In order to comply with applicable data protection law, we only process your personal data on the basis of a statutory authorization or if you have declared your consent.
On this Website we may collect information that does not allow us to draw any direct conclusions about your person. In certain cases - especially when combined with other data - this information can nevertheless be considered as "personal data" under applicable data protection law. Furthermore, we may also collect information on this Website that does not enable us to identify you, directly or indirectly; this is the case, for example, with aggregated information about all users of this Website.
III. Which data do we process?
You can access our Website without entering personal data (such as your name, your postal address or your e-mail address). Also in this case we must process certain information to enable you to access our Website. In addition, we use certain analysis methods on this Website and have integrated third-party functionalities ("social plug-ins").

1. Logfiles: When you visit this Website, our web server automatically stores the domain name or IP address of the requesting computer (usually a computer of your internet access provider) including the date, time and duration of your visit, the subpages/URLs you visit and information about the application(s) and terminal(s) you use to view our pages.

2. Cookies: In order to make our Website as user-friendly as possible, we - like many other website operators - use cookies. Cookies are small text files that are stored in your browser. These files help us to recognize certain preferences of our visitors when surfing and to design our site accordingly. Most of the cookies we use are session cookies. They are automatically deleted at the end of your visit. However, we also use permanent cookies. These serve to improve user guidance. Our cookies do not collect any personal data and are not suitable for identifying you on third-party Websites. You can set your browser so that it informs you about the placement of cookies so that the use of cookies becomes transparent for you. In principle, you can also refuse the acceptance of cookies via your browser settings. However, this may mean that you may not be able to use all the functions of the Website.

3. Website analysis via Google Analytics: We use Google Analytics, a web analysis service of Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA ("Google"), on our Website to continuously improve our Website. Google Analytics uses cookies which are stored on your computer and which enable analysis of the use of the Website. The information generated by the cookie about your use of this Website is usually sent to a Google server in Europe (or in a member state of the European Economic Area) for the anonymization of the IP address, so that a personal reference is excluded. Only after the IP address was anonymized the shortened IP address is transferred to a Google server in the US and stored there. Only in exceptional cases the full IP address will be transferred to a Google server in the US and shortened there. This Website uses Google Analytics with an extension for the anonymous collection of IP addresses (so-called IP masking). On our behalf, Google will use the collected information to evaluate your use of the Website, to compile reports on Website activity and to provide us with other services relating to Website use. The IP address transmitted by your browser in the context of Google Analytics is not combined with other Google data. You may refuse the use of cookies by selecting the appropriate settings on your browser. However, we would like to point out that in this case you may not be able to use all functions of this Website in full. You can also prevent Google from collecting the data generated by the cookie and relating to your use of the Website (including your IP address) and from processing this data by Google by downloading and installing the browser plug-in available under the following link:

An opt-out cookie is set which prevents the future collection of your data when you visit this Website. Further information on data protection at Google Analytics can be found at here and here

5. Facebook Social Plugin: We have integrated a button of Facebook on our Website. You can recognize the Facebook buttons by the Facebook logo or the "Like" button.
In order to prevent the automatic collection of information by Facebook as soon as our Website is accessed, we have implemented the so-called "two-click solution": Next to the Facebook button there is another area that looks like a switch. Only when you press this switch and then click the Facebook button again, information (such as the address of our Website and your user ID) is sent to Facebook.
As the operator of this Website, we have no knowledge of the content of the transmitted data or its use by Facebook. We do not know when you clicked which button. For more information on how Facebook uses your information, please see Facebook's Privacy Policy [].

6. Twitter button: Our Website uses the buttons of the Twitter service. These buttons are provided by Twitter Inc, 795 Folsom St., Suite 600, San Francisco, CA 94107, USA. They are recognizable by terms such as "Twitter" or "Follow", combined with a stylized blue bird. With the help of the buttons it is possible to share a post or page of this offer on Twitter or to follow the provider on Twitter. When you access an area of our Website that contains such a button, your browser establishes a direct connection to Twitter's servers. The content of the Twitter button is transmitted directly from Twitter to your browser. We therefore have no influence on the amount of data Twitter collects with the help of these plug-ins and inform you exclusively on the basis of the information available to us. Thereafter, only your IP address and the URL of our Website will be transmitted when the button is purchased, but will not be used for any other purposes than the display of the button. Further information can be found in the Twitter data protection declaration at

7. Google+ button: Our Website uses the "+1″ button of the social network Google Plus, which is operated by Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States ("Google"). The button can be recognized by the sign "+1″ on a white background. When you visit an area of our Website that contains such a button, your browser establishes a direct connection to Google's servers. The content of the "+1″ button is transmitted by Google directly to your browser and integrated into the Website. We therefore have no control over the amount of data Google collects using the button, but we assume that your IP address will also be recorded. The purpose and scope of the data collection and the further processing and use of the data by Google as well as your rights and setting options for the protection of your privacy can be found in Google's privacy policy for the "+1″ button: . If you are a Google Plus member and do not want Google to collect data about you via our Website and link it to your membership data stored on Google, you must log out of Google Plus before visiting our Website

Only in connection with the use of service providers to provide web analysis services information may be transferred to recipients in so-called "third countries".

If the information transferred contain personal data, we ensure before such a transfer that the necessary adequate level of data protection is guaranteed in the respective third country or with the recipient in the third country. This may result in particular from a so-called "adequacy resolution" of the European Commission, which establishes an appropriate level of data protection for a certain third country as a whole. Alternatively, we can also base data transmission on the so-called "EU standard contract clauses" agreed with a recipient or - in the case of recipients in the USA - on compliance with the principles of the so-called "EU-US Privacy Shield". We will be happy to provide you with further information on the appropriate and appropriate guarantees for maintaining an appropriate level of data protection upon request; the contact details can be found at the beginning of this data protection information.
