We use the provider Hubspot, 25 First Street, 2nd Floor, Cambridge, MA 02141, USA, to send newsletters. Hubspot is a service with which the dispatch of newsletters can be organized and analyzed. For this purpose, we forward your e-mail address and the information whether you have signed up for the newsletter and/or for further product information to Hubspot. With the help of Hubspot, we can analyze our newsletter campaigns. When you open an email sent with Hubspot, a file contained in the email (known as a web beacon) connects to Hubspot servers in the USA. This allows us to determine whether a newsletter message was opened and which links were clicked. In addition, technical information is collected (e.g. time of registration, IP address, browser type and operating system). This information is used for statistical analysis of newsletter campaigns. The results of these analyses can be used to better adapt future newsletters to the interests of the recipients.

We use various third-party tools on our website, in particular for the purpose of online marketing. These tools can be used to store user profiles or similar procedures, by means of which relevant information about the user is stored. In addition to the IP address, this information may include, for example, content viewed, websites visited, online networks used, but also communication partners and technical information such as the browser used, the computer system used and information on usage times. The information in the profiles is usually stored in the cookies (see above) or by means of similar procedures. Exceptionally, clear data can be assigned to the profiles. This is the case if, for example, the users are members of a social network whose online marketing procedures we use and the network links the users' profiles to the aforementioned data. We ask to note that users may make additional arrangements with the providers, e.g., by giving consent as part of the registration process. In principle, we only receive access to summarized information about the success of our advertisements. However, in the context of so-called conversion measurements, we can check which of our online marketing processes have led to a so-called conversion, i.e., for example, to a conclusion of a contract with us. The conversion measurement is used solely to analyze the success of our marketing measures. The tools used are:

  • Google Analytics Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland,; Privacy policy:; Opt-out: Opt-out plugin:, Settings for the display of advertising:
  • Google Tag Manager Google Tag Manager is a solution with which we can manage so-called website tags via an interface and thus integrate other services into our online offer.

  • Google Ads and Conversion Measurement We use the online marketing method “Google Ads” to place ads in the Google advertising network (e.g., in search results, in videos, on web pages, etc.) so that they are displayed to users who have a presumed interest in the ads. Furthermore, we measure the conversion of the ads. However, we only learn the anonymous total number of users who clicked on our ad and were redirected to a page tagged with a so-called “conversion tracking tag”. However, we ourselves do not receive any information that can be used to identify users.

Social Media

We are represented on the following social media platforms and process user data in this context in order to communicate with users active there or to offer information about us:

We point out that user data can be processed within social networks for market research and advertising purposes. For example, usage profiles can be created based on the usage behavior and resulting interests of the users. The usage profiles can in turn be used, for example, to place advertisements within and outside the networks that presumably correspond to the interests of the users. For these purposes, cookies are usually stored on the computers of the users, in which the usage behavior and the interests of the users are stored. Furthermore, data independent of the devices used by the users may also be stored in the usage profiles (especially if the users are members of the respective platforms and are logged in to them). For a detailed presentation of the respective forms of processing and the options to object (opt-out), we refer to the privacy policys and information provided by the operators of the respective social media providers. In the case of information requests and the assertion of data rights, we also point out that these can be asserted most effectively with the providers. Only the providers have access to the users' data and can take appropriate measures and provide information directly. If you still need help, don’t hesitate to contact us.
