We are delighted that you are interested in our products and services and want you to feel secure when visiting our website, including in respect of protection of your personal data. We take the protection of this very seriously. It goes without saying that we adhere to the provisions of the General Data Protection Regulation (GDPR).

We would like you to know which data we collect, when we collect it and how we use it. We have taken technical and organisational measures to ensure that the data protection regulations are observed not only by us, but also by external service providers commissioned by us.

Personal data

Personal data is information about your identity. It includes, for example, data such as name, address, telephone number and email address. It is not necessary for you to divulge your personal data in order to use our website. In certain cases, however, we require your name and address as well as further data so that we can render the desired services.

This applies, for example, to the sending of information material and goods that you have ordered, or for answering individual questions. We will inform you accordingly where this is necessary. Beyond that we store and process only data that you voluntarily place at our disposal and, where applicable, data that we automatically collect when our website is visited (see: ‘Data collected automatically when visiting our website’).

In cases where you use our services, we generally only collect such data as is necessary in order to render these services. Any further data that we ask for is supplied by you voluntarily. Personal data is processed exclusively for the fulfilment of the requested service and for the protection of our own justified business interests.

Purpose of the personal data

In general, we use the personal data supplied by you in order to answer your enquiries, to process your orders or to provide you with access to certain information or offers. For the maintenance of customer relations it may also be necessary for us or a service provider commissioned by us to use this personal data in order to inform you about product offers or to conduct online surveys in order to improve our handling of the customers’ tasks and requirements.

Naturally we will respect your decision, should you not want to provide us with your personal data for the support of our customer relations (in particular for direct marketing or for market research purposes). We will neither sell your personal data to third parties nor market it in any other way.

Neither will any personal data be passed on to any countries outside the EU or EEA.

Google Analytics

We use Google Analytics, a web analytics service provided by Google, Inc. (“Google”). Google Analytics uses cookies. The information generated by the cookie about your use of this website (including your IP address) will be transmitted to and stored by Google on a server in the United States. Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity for website operators and providing other services relating to website and Internet usage. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google’s behalf. Google will not associate your IP address with any other data held by Google. You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website. By using this website, you consent to the processing of data about you by Google in the manner and for the purposes set out above. Website visitors can at any time opt out of having their data collected or stored from that point forward. In view of the discussion concerning the use of analytical tools with complete IP addresses, we would like to point out that this website uses Google Analytics with the extension ‘_anonymizeIp ()’ and that IP addresses are therefore further processed only in a shortened form in order to prevent the establishment of a direct connection to a specific individual.


We have taken technical and organisational security measures to protect your personal data from loss, deletion, manipulation or unauthorised access.

All our employees and everyone else involved in the data processing are required to adhere to the provisions of the General Data Protection Regulation (GDPR) and of all other related laws and to handle personal data confidentially.

Our security measures are revised on a continual basis in line with technological developments.

Changes to our data protection regulations

We reserve the right to change our security and data protection measures if necessary due to technical developments. In such cases we will also adapt our data protection notices accordingly. Therefore, please always note the current version of our data protection declaration.


If you use external links offered on our web pages, this data protection declaration does not extend to these links. Insofar as we provide links, we assure you that there were no recognisable breaches of applicable laws on the web pages linked to when the links were added. However, we have no influence on the adherence of other providers to the data protection and security regulations. Therefore, please refer to the data protection declarations provided on the web pages of the other providers.

Online presence on social media

We maintain an online presence on social networks and platforms in order to be able to communicate with customers, prospects and users who are active there and to be able to inform them there about our services.

Please note that this may involve users' data being processed outside of the European Union. This can result in certain risks for users, as, for example, the assertion of users' rights could become more difficult. In respect of US providers certified under the Privacy Shield, please be advised that they undertake to adhere to EU data protection standards.

Furthermore, users' data is as a rule processed for market research and advertising purposes. It is possible, for example, that usage profiles may be created from usage patterns and the users' interests that they suggest. The usage profiles can in turn be used in order, for example, to show advertisements on and outside of the platforms that are presumed to correspond to the users' interests. For these purposes cookies are generally placed on the users' computers to store the users' interests and usage behaviour. Furthermore it is possible for the data that gets saved in the usage profiles to include data independent of the devices used by the user (especially if the users are members of the respective platforms and are logged in to them).

The processing of users' personal data takes place on the basis of our legitimate interest in effective provision of information to and communication with users as per GDPR Article 6.1.f. If the users are asked by the respective provider to give their consent for the data processing (i.e. to declare their agreement by checking a checkbox or clicking a button), the legal basis for the processing is Article 6.1.a and Article 7 of the GDPR.

For a detailed account of how the data is processed in each case and how you can opt out, please refer to the providers' information linked to below.

Please note too that requesting information or asserting user rights can be done most effectively by contacting the providers. In each instance only the providers have access to the user data and can immediately take appropriate action and provide information. If you do nevertheless need help, you can also contact us.

Link buttons to social networks and mail programmes

External links on our website enable you to share content by mail or on social networks. If you utilise this option, you are forwarded by clicking the button to the site of the respective provider. Corresponding user information gets passed on in the process.

If while using our site you are logged in with your account on one of these social networks and want to share our content, this information gets linked to your account for that network. We as the operator of our site have no influence over the data that gets relayed by link buttons to corresponding servers. Generally the IP address gets transferred.

For more information on how your data is handled please refer to the respective provider's data protection declaration:

We use YouTube in connection with the 'Enhanced Data Protection Mode' function in order to be able to show you videos. The legal basis is Art. 6.1.f of the GDPR. Our legitimate interest lies in improving the quality of our website. According to information from YouTube, the effect of the 'Enhanced Data Protection Mode' function is that the data described more precisely below is relayed to the YouTube server only if you actually start a video.

Without this 'Enhanced Data Protection' a connection is made to the YouTube server in the USA as soon as you open any of our website pages on which a YouTube video is embedded.

This connection is necessary in order to be able to show the respective video on our website via your Internet browser. In the course of this, YouTube captures and processes at least your IP address, the date, the time and the website page you visited. A connection is also established to Google's 'DoubleClick' advertising network.

If you are logged in at that same time to YouTube, YouTube assigns the connection information to your YouTube account. If you want to prevent this, you must either log out of YouTube before you visit our site or adjust the settings in your YouTube user account accordingly.

For the purposes of functionality and for analysing patterns of usage, YouTube permanently saves cookies on your device via your Internet browser. If you do not agree with this processing, you are able to prevent the saving of cookies via a setting in your Internet browser. You will find more detailed information on this above under 'Cookies'.
