III. General remarks concerning data protection
1. Scope in which personal data is processed

Our website can generally be used without providing personal data. As a matter of principle, we only process personal data of our users where this is necessary for the provision of a functional website as well as our contents and services.

2. Legal basis for the processing of personal data

Where we obtain the consent of the data subject for the processing of personal data, the legal basis is Art. 6 para. 1 point a) EU General Data Protection Regulation (GDPR).

The legal basis for the processing of personal data for the performance of a contract or fulfilment of our services is Art. 6 para. 1 point b) GDPR. This applies also to processing that is carried out to take steps prior to entering into a contract.

Where the processing of personal data is necessary in order to protect the vital interests of the data subject or of another natural person, the legal basis is Art. 6 para. 1 point d) GDPR.

We set out the relevant legal basis for the processing of personal data in each of the processing operations described below.

3. Data erasure and duration of storage

The personal data of the data subject will be erased or blocked as soon as the purpose of their storage no longer applies. In addition, storage may take place if this has been provided for by the European or national legislator in Union regulations, laws or other provisions to which the controller is subject. Data will also be blocked or erased if a storage period prescribed by the aforementioned standards expires, unless continued storage of the data is necessary to enter into a contract or for the performance of a contract.

The erasure period will be specified in connection with processing operations to which an erasure period applies.

4.  Cooperation with processors and third parties

In the event that we transfer data to other persons and enterprises (processors or third parties) or otherwise grant them access to the data in connection with our data processing, this shall only take place on the basis of legal permission, your consent, a legal obligation, for the fulfilment of contractual relationships with you or if we have a legitimate interest in the transfer of data (e.g. when using authorised representatives or web hosting providers, etc.). Where we commission third parties with the processing of data within the framework of a “Data Processing Agreement”, this shall take place on the basis of Art. 28 GDPR.

5. Data security

We use the common SSL technology (Secure Socket Layer) on our website in connection with the highest encryption level supported by your browser in each case. This is usually 256-bit encryption. We revert to 128-bit v3 technology in the event that your browser does not support 256-bit encryption. You can tell whether a page on our internet presence is transferred in an encrypted form by the presence of a key or padlock symbol in the lower status bar of your browser. We otherwise implement suitable technical and organisational security measures to protect your data against coincidental or wilful manipulation, partial or complete loss, destruction or against unauthorised access by third parties. Our security measures are improved continuously in line with the state of the art.

6. Profiles on social media

It has been established by the highest courts that the operators of profiles, also association profiles, in social media are jointly responsible with the network operator for data processing in connection with these profiles.

We operate association profiles on social networks and platforms to communicate with interested persons and users who are active there and to inform them about our services. The privacy policies issued by the respective operators of the social networks and platforms apply when their services are accessed.

Except where otherwise stated in our privacy policy, we process the data of users insofar as they communicate with us on the social networks and platforms, i.e. they post comments on our internet presences or send us messages.

(2) We use the technical platform and services of the providers for these information services. Please note that you use our services on social media platforms and their features at your own risk. This applies in particular to the use of interactive features (e.g. commenting, sharing, rating). When you visit our accounts, the providers of the social media platforms collect, among other things, your IP address and other information that is stored on your device in the form of cookies. This information is used to provide us, as the operator of the accounts, with statistical information about your interaction with us.

(3) The data collected about you in this context is processed by the platforms and may be transferred to countries outside the European Union, in particular the USA. According to their own statements, all of the aforementioned providers maintain an adequate level of data protection that conforms to that of the former EU-US Privacy Shield. We are not aware of how the social media platforms use the data from your visit to our account and interaction with our posts for their own purposes, how long these data are stored and whether data are passed on to third parties. Data processing may differ depending on whether you are registered and logged in to the social network or are visiting the site as a non-registered and/or non-logged-in user. When you access a post or the account, the IP address assigned to your device is transmitted to the provider of the social media platform. If you are currently logged in as a user, a cookie on your device can be used to track how you have navigated the network. Buttons embedded in websites enable the platforms to record your visits to these website pages and associate them with your respective profile. These data can be used to target content or advertising specifically to you. If you want to avoid this, you should log out or disable the “stay logged in” option, delete the cookies on your device and restart your browser.

(4) As the provider of the information service, we also only process the data from your use of our service that you provide to us and requires interaction. For example, if you ask a question that we can only answer by email, we will store your information in accordance with the general principles of our data processing, as described in this Privacy Policy. The legal basis for processing your data on the social media platform is Art. 6 para. 1 sentence 1 point f) GDPR.

(5) To exercise your rights as a data subject, you can contact both us or the provider of the social media platform. If one party is not responsible for responding or must receive the information from the other party, we or the provider will then forward your request to the respective partner. Please contact the operator of the social media platform directly for any questions about profiling or processing of your data when using the website. For questions about the processing of your interaction with us on our page, write to us using the contact details we have provided above.

You can also find information in them on the options for contacting them as well as on the settings for advertisements. Further information on social networks and how you can protect your data is also available at

Embedding of YouTube videos

When you play the videos, the data referred to in paragraph 2 will be transmitted. We have no influence over this data processing. The legal basis for this data processing is Art. 6 para. 1 sentence 1 point a) GDPR, which means embedding takes place only with your consent.

(2) By visiting our website, YouTube receives information that you have accessed the corresponding sub-page of our website. In addition, the aforementioned basic data such as IP address and time stamp are transmitted. This takes place irrespective of whether YouTube has provided a user account and you are logged in, or whether a user account exists at all. The data will be directly associated with your account if you are logged into Google. You must log out of your account before selecting the button if you do not want the data to be associated with your YouTube profile. YouTube stores your data as a user profile and uses them for the purposes of advertising, market research and/or the audience-based design of its website.
