General principle

The operators of these pages take the protection of your personal data very seriously. We treat your personal data confidentially and in accordance with statutory data protection regulations and with this privacy statement.
In general it is possible to use our website without entering any personal data. If we collect any personal information (e.g. your name, address or e-mail address), this is always done on a voluntary basis where possible. These data will not be passed onto third parties without your explicit approval.
Please note that data transfer on the Internet (e.g. when communicating by e-mail) may involve lapses in security. It is not possible to protect the data entirely against third-party attacks.


Some of our Internet pages use what are known as “cookies.” Cookies do not damage your computer or contain any viruses. Cookies are used to make our service more user-friendly, effective and safe. Cookies are small text files which are filed on your computer and saved by your browser.
Most of the cookies we use are “session cookies”, which are automatically deleted at the end of your visit. Other cookies are stored on your device until you delete them. These cookies allow us to recognise your browser on your next visit.
You can set your browser to tell you when cookies are set, only to allow certain cookies, to accept cookies in certain cases, to exclude them generally and to automatically delete cookies when you close your browser. If you deactivate cookies, the functions on this website may be limited.

Server log files

The provider of this site automatically collects and store data in “server log files” which your browser automatically transmits to us.

This consists in:

  • browser type and version
  • operating system used
  • referrer URL
  • host name of the accessing computer
  • date and time of request to server

These data are not attributable to any specific persons. These data are not merged with other data sources. We reserve the right to check this data retrospectively if we become aware of any specific indications of illegal use.

Please note that you can set up your browser so as to be informed when cookies are placed and decide whether to accept them individually, to accept cookies in certain cases or to disable them generally. Every browser uses a different means of managing cookie settings. This is described in the “help” menu of every browser, which explains how you can change your cookie settings. Depending on your browser, these can be found via the following links:

Contacting us

When you contact us (e.g. via the contact form or by e-mail), personal data are collected. When a contact form is used, the data it collects can be seen from the form itself. These data are stored and used solely for the purpose of replying to your query or for us to contact you, and for related technical administration purposes. The legal basis for processing the data is our legitimate interest in answering your query in accordance with Article 6 (1f) of the GDPR. If you are contacting us with the intention of concluding a contract, then another legal basis for the processing is Article 6 (1b) of the GDPR. Once your query has been processed, your data will be erased. That is the case if circumstances indicate that the issue in question has been finally resolved, and if no statutory record-keeping duties stand in the way.

Registration / log-in area

The data subject has the option of going online and logging into the controller's website, entering his or her username and password. The data which are transmitted to the controller during this process depends on the web form used for the log-in. The data entered by the data subject are collected and saved solely for internal use by the controller and for the controller’s own purposes. The controller may arrange for the data to be disclosed to one or more processors which also use the data only for internal purposes attributable to the controller.

When the data subject registers on the controller’s website, his or her IP address, allocated by his or her internet service provider (ISP), the date and the time of registration are also saved. These data are saved as this is the only means of preventing our services from being misused, and because these data enable criminal acts to be investigated where required. As such, these data need to be stored to protect the controller. These data are generally not disclosed to third parties unless there is a legal obligation to disclose them, or their disclosure is for the purpose of criminal prosecution.

If the data subject registers, thereby voluntarily providing personal data, this enables the controller to offer the data subject content or services which by their nature can only be offered to registered users. The registration and allocation of login details (username and password) does not take place by means of the options offered on this page. At any time, registered persons have the opportunity to alter the personal data they provide upon registration or to have it erased entirely from the controller’s database.

Upon request, the controller shall at any time provide the data subject with information on what personal data is stored relating to the data subject. Furthermore, the controller shall correct or erase data at the request or indication of the data subject, to the extent that no statutory record-keeping duty stands in the way.

Information on embedded videos

On our Internet site, we use videos. We use means offered by third parties to embed our videos. When videos are embedded, requests are sent to the providers’ servers for technological reasons.


Our website uses plugins from the YouTube site, run by Google. The site is operated by YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. If you visit a page on our site which contains a YouTube plugin, a connection is made to the YouTube servers.

Use of Google Maps

On our site we use the “Google Maps” widget, provided by Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA, hereinafter referred to as “Google”.

Whenever the “Google Maps” widget is called up, Google places a cookie which enables user settings and information to be processed when the page in which the “Google Maps” widget is embedded is displayed. This cookie is generally not erased when the browser is closed, but instead expires after a certain time, unless it is previously deleted manually by you.

If you do not wish your data to be processed in this manner, you have the opportunity to deactivate the “Google Maps” service and thus prevent data from being transmitted to Google. To do so, you will need to deactivate the JavaScript function in your browser. However, please note that in this case, you may not be able to use all the functions of “Google Maps”, or not to their full extent.

“Google Maps” and the information obtained via “Google Maps” are used in accordance with the Google Terms of Service.

and the “Google Maps” Additional Terms of Service .

Rights of the data subject

Current data protection law grants you comprehensive rights (rights of access and intervention) as a data subject with regard to the controller, information about which we provide you with below:

  • Right of access pursuant to Article 15 of the GDPR: among other things, you have a right to obtain access to the personal data concerning you which we process, the purposes of the processing, the categories of personal data concerned, the recipients or categories of recipients to whom your data have been or will be disclosed, the envisaged period for which the data will be stored or the criteria used to determine that period, the existence of the right to request rectification, erasure, restriction of processing, the right to lodge a complaint with a supervisory authority; where your data are not collected by us from you the right to information as to their source, the existence of automated decision-making, including profiling, and, in certain cases, meaningful information about the logic involved, as well as the significance and envisaged consequences of such processing for you, and the right to be informed of the appropriate safeguards pursuant to Article 46 relating to the transfer of your data to a third country;
  • Right to rectification pursuant to Article 16 of the GDPR: you have the right to obtain without undue delay the rectification of inaccurate personal data concerning you, and/or to have your incomplete personal data stored by us completed;
  • Right to erasure pursuant to Article 17 of the GDPR: you have the right to obtain the erasure of personal data concerning you without undue delay where one of the grounds in Article 17 (1) of the GDPR applies. However, this right shall not exist to the extent that such processing is necessary for exercising the right of freedom of expression and information, for compliance with a legal obligation, for reasons of public interest or for the establishment, exercise or defence of legal claims;
  • Right to restriction of processing pursuant to Article 18 of the GDPR: you have the right to obtain the restriction of the processing of your personal data where the accuracy is contested, for a period enabling their accuracy to be verified; where the processing is unlawful but you oppose the erasure of the personal data and request the restriction of their use instead; where we no longer need the personal data for the purposes of the processing but you require your data for the establishment, exercise or defence of legal claims, or where you have objected to processing on grounds relating to your particular situation, pending the verification whether our legitimate grounds override yours;
  • Right to notification pursuant to Article 19 of the GDPR: if you have exercised your right to rectification or erasure of personal data or restriction of processing with regard to the controller, the controller is obliged to communicate that rectification or erasure of personal data or restriction of processing to each recipient to whom the personal data concerning you have been disclosed, unless this proves impossible or involves disproportionate effort. You have the right to be informed about these recipients.
  • Right to data portability pursuant to Article 20 of the GDPR: you have the right to receive the personal data concerning you, which you have provided to us, in a structured, commonly used and machine-readable format or to demand that they be transmitted to another controller to the extent that this is technologically feasible;
  • Right to withdraw your consent which you gave previously, pursuant to Article 7(3) of the GDPR: you have the right at any time to withdraw any consent that you grant us with future effect. If you withdraw your consent, we will immediately erase the data in question, to the extent that their further processing is not supported by a legal basis for processing them without consent. The withdrawal of consent shall not affect the lawfulness of processing based on consent before its withdrawal;
  • Right to lodge a complaint pursuant to Article 77 of the GDPR: if you consider that that the processing of personal data relating to you infringes the GDPR, you have the right, without prejudice to any other administrative or judicial remedy, to lodge a complaint with a supervisory authority, in particular in the Member State of your habitual residence, place of work or place of the alleged infringement.

SSL encryption

This site uses SSL encryption for security reasons and to protect the transmission of confidential data, such as the enquiries you send us as the operator of this site. You can recognise an encrypted connection from the fact that the browser address bar changes from “http://” to “https://” and from the lock symbol in your browser bar. If SSL encryption is activated, the data you send us cannot be read by third parties.

Right to access, erase and block data

You have a right at any time and free of charge to access the personal data saved regarding you, their origin and recipient and the purpose of their processing, as well as a right to have such data rectified, made unavailable or erased. For information on this, or other questions on the subject of personal data, you can contact us at any time at the address given in the legal notice.

If you have any questions which this privacy statement does not answer, or if you have questions about the processing of your personal data, you can enquire with our data protection officer, who is also available to respond to requests for information, suggestions or complaints.
