Personal data

Personal data is any information about you. This includes your name, your postal address, and your email address. The disclosure of any personal data is not a prerequisite for visiting our website. In certain cases, we will need your name, address, and other information in order to be able to provide you with the requested services. 

The same applies in the event that we supply you with information material upon request and/or respond to your enquiries. In these cases, we will always draw your attention to this fact. Furthermore, we will only retain information that you have provided to us automatically or voluntarily.

As a general rule, if you use any of our services, we will only collect information that is required for the provision of our service to you. We may ask you for additional information that may be disclosed on a voluntary basis. Whenever we process personal data, we will do so to be able to offer you our services or to pursue our business objectives.


Automatically stored data 

Server log files 

The provider of the web pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These include:


  • the date and time of the request;
  • the name of the requested file;
  • the site from which the file was requested;
  • the access status (file transferred, file not found, etc.);
  • the web browser used and operating system used;
  • the full IP address of the requesting computer;
  • the volume of data transmitted.


This data shall not be combined with other sources of data. Data is processed in accordance with Art. 6 Par. 1 letter f of the GDPR based on our legitimate interest in improving the stability and functionality of our website.   

This data is stored by us temporarily for reasons of technical security, in particular to combat attempted attacks on our web server. Conclusions about individual persons cannot be drawn using this data. Data shall be anonymised by truncating the IP address at the domain level after seven days at the latest so that it is no longer possible to establish a link to individual users. The data shall also be processed for statistical purposes in anonymised form; there shall be no comparison with other data sets, nor shall it be shared with third parties, even in excerpts. Only in the context of our server statistics, which we publish in our activity report every two years, do you get an illustration of the number of site visits.

Google analytics with anonymisation function

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 uses so-called “cookies”, text files that are stored on 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 USA and stored there.

In using Google Analytics, our website employs the extension, “_gat._anonymizeIp”. Hereby, Google abbreviates and anonymises 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 uses this information to analyse your use of our site, to compile reports for us on Internet activity, and to provide other services relating to website and Internet use. Google may also transfer this information to third parties where required to do so by law or where such third parties process this data on Google’s behalf.

Google states that it will 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.

Furthermore, Google offers a deactivation add-on for most current browsers that provides you with more control over what particular data Google can collect on the websites that you access. The add-on tells the JavaScript (ga.js) used by Google Analytics not to transmit any information about website visits to Google Analytics. However, the browser deactivation add-on offered by Google Analytics does not prevent information from being transmitted to us or to other web analysis services we may use. You can find additional information on how to install the browser add-on at the following link:


If you have granted Google your consent to the linking of your web and app browser history to your Google account and the use of information from your Google account for the personalisation of advertisements, Google will use your data in combination with Google Analytics data in order to generate target group lists for cross-device remarketing. For this purpose, Google Analytics will initially capture your Google-authenticated ID on our website, which is linked to your Google account (including personal data). Subsequently, Google Analytics will temporarily link your ID to your Google Analytics data in order to optimise our target groups.

If you do not agree, you may disable this function by making corresponding settings in the “My account” section of your Google account.


Google ad services / Google AdWords conversion tracking

This website uses tools for “online marketing” from Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. This is used to identify that a visitor has landed on our website via a Google ad. Google uses cookies that are stored on your computer and make it possible to analyse website use. The cookies for so-called “conversion tracking” are set if you click an ad placed by Google. These cookies lose their validity after 30 days and are not used for personal identification. You can prevent “conversion tracking” by configuring your browser to block cookies from the domain “”. You can also exercise your right to opt-out.

Google reCAPTCHA

We use the reCAPTCHA service provided by Google Inc. (Google) to protect online forms submitted by you. The request is used to distinguish whether information is entered by a human or fraudulently by automated software. A request is sent to Google containing your IP address plus any other data required by the reCAPTCHA service. Your input is communicated to Google for this purpose and for further use. By using reCAPTCHA, you give your consent for your text recognition entry to be used by Google for the digitisation of old books, etc. If IP anonymisation is activated on this website, your IP address will be truncated beforehand by Google within Member States of the European Union or in the countries and territories of other signatories of the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be sent to a Google server in the USA and shortened there. On behalf of the operator of this website, Google will use this information to evaluate your use of this service. The IP address transmitted by your browser within the framework of reCaptcha is not associated with any other data held by Google. Google’s own data protection provisions apply to this data. More information on Google’s data privacy policies is available at:


Google web fonts

For the standardised display of fonts, this website uses so-called web fonts that are provided by Google. When you access a web page, your browser loads the necessary web fonts to your browser cache in order to correctly display texts and fonts. If your browser does not support web fonts, a standard font will be used by your computer.

For more information on Google Web Fonts, please refer to and Google’s data privacy policy:


Matomo (formerly PIWIK) (web analysis service)

Your IP address is immediately anonymised during this process so that you as a user remain anonymous to us. The information generated by the cookie about your use of this website is not passed on to third parties.

Right to rectification:

If we process your personal data, and if it is incomplete or incorrect, you may demand, at any time, that we correct or supplement it.

Irrespective of your right to erasure, we will delete your data immediately and completely unless such action is prevented by an applicable contractual or legal retention requirement.


Right to restriction of processing:

You may demand that we limit the processing of your data if

-             you dispute the accuracy of the data, that is for such a period of time that we can verify its correctness;

-             processing the data is illegal, but you are opposed to its deletion and demand limitation of its use instead;

-             we no longer need the data for the intended purpose, but you still need it to assert or defend any claims; or

-             you have filed an objection against the processing of the data.


Right to data portability:

You have the right to receive the data, which you have provided to us, in a structured, commonly used, and machine-readable format, and have the right to transmit this data to another responsible party without hindrance from us, provided that:

If technically feasible, you have the right to have your data transmitted directly to another responsible party by us.


Right to object:

If we process your data on the basis of legitimate interests, you have the right to object to this processing at any time; this also applies to profiling based on these provisions. We shall then no longer process your data unless we can demonstrate compelling, legitimate grounds for its processing, which override your interests, rights, and freedoms or for the establishment, exercise, or defence of legal claims. You have the right to object to the processing of your data for direct marketing purposes at any time, without stating a reason.


Right of complaint:

If you believe that we are processing your data in violation of German or European data protection law, please contact us to clear up any questions. You are of course entitled to file a complaint with the supervisory authority responsible, i.e. the respective State Data Protection Authority.

If you want to assert any of the above-mentioned rights vis-à-vis our company, please contact our Data Protection Officer. In cases of doubt, we may request additional information to confirm your identity.
