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 offer you the opportunity to post comments about individual articles. For this purpose, the IP address of the user/internet connection subscriber is stored. This information is stored for our security in the event the author through his/her comments infringes against third party rights and/or unlawful content is entered. Consequently, we have a direct interest in the author’s stored data, particularly since we may be potentially liable for such violations. No data is transferred to third parties.

Use of Google Analytics with anonymization
Our website uses Google Analytics, a web analysis service from Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043 USA, hereinafter referred to as “Google“. Google Analytics employs so-called “cookies“, text files that are stored to your computer in order to facilitate an analysis of your use of the site.
The information generated by these cookies, such as time, place and frequency of your visits to our site, including your IP address, is transmitted to Google’s location in the US and stored there.
We use Google Analytics with an IP anonymization feature on our website. In doing so, Google abbreviates and thereby anonymizes your IP address before transferring it from member states of the European Union or signatory states to the Agreement on the European Economic Area.
Google will use this information to evaluate your usage of our site, to compile reports on website activity for us, and to provide other services related to website- and internet usage. Google may also transfer this information to third parties if this is required by law or to the extent this data is processed by third parties on Google´s behalf.
Google states that it will in never associate your IP address with other data held by Google. 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.
Google also offers a disabling option for the most common browsers, thus providing you with greater control over the data which is collected and processed by Google. If you enable this option, no information regarding your website visit is transmitted to Google Analytics. However, the activation does not prevent the transmission of information to us or to any other web analytics services we may use. For more information about the disabling option provided by Google, and how to enable this option, visit https://tools.google.com/dlpage/gaoptout?hl=en
Use of Google+ recommendation components
Our website employs the “+1“-buttom from Google+ belonging to Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043 USA, hereinafter referred to as “Google“. Each time our website receives an access request equipped with a “+1“ component, the component prompts your browser to download an image of this component from Google. Through this process, Google is informed precisely which page of our website is being visited. As specified by Google, your visit undergoes additional analysis in the event you are not logged into your Google account. If you access our site while logged into Google and press the “+1" button, Google can collect information about your Google account, websites you recommend as well as your IP address, along with other browser-related information. This allows your “+1“ recommendation to be stored and publicized. Your Google “+1“ recommendation can then appear as a reference in other Google services, such as search results, your Google account or other places, such as on websites and ads in the internet, , together with your account name and, if applicable, a picture you provided to Google. Furthermore, Google can link your visit to our site with data stored by Google. Google also records this information for the purpose of further improving Google services. If you wish to minimize the collection of information by Google as previously described, you must log out of your Google account before visiting our website.

According to the information provided by YouTube, in “ - enhanced data protection mode -”, data is only transferred to the YouTube server, in particular which of our websites you have visited, if you watch the video. If you are logged onto YouTube at the same time, this information will be matched to your YouTube member account.

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.

Use of Google-Adwords
For purposes of promotion, our website also employs the Google ad tool "Google-Adwords". As part of this, our website employs the analysis service "Conversion-Tracking" from Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043 USA, hereinafter referred to as “Google“. If you access our site by way of a Google ad, a cookie is placed on your computer. Cookies are small text files that your internet browser downloads and stores to your computer. These so-called "conversion cookies" cease to be active after 30 days and are not used to identify you personally. If you visit certain pages of our website while the cookie is still active, we and Google know that you, as user, have clicked on ads placed on Google and were redirected to our site. Google uses the information obtained through "conversion cookies" to compile statistics for our website. These statistics tell us the total number of users who have clicked on our ad as well as which pages of our site were then accessed by each user. However, neither we nor other advertisers who use "Google-Adwords" receive any kind of information that can be used to personally identify users. You can prevent the installation of "conversion cookies" by making the appropriate change to your browser settings, for example by setting your browser so that the automatic placement of cookies is deactivated or by blocking cookies from the domain "googleadservices.com“.
