The IP addresses collected via the log files are stored and deleted after 30 days.

This data is not analysed for marketing purposes. Our legitimate interest in data processing lies in the aforementioned purposes. The legal basis for the collection and temporary storage of the aforementioned data is Art. 6 para. 1 lit. f GDPR.

Data collection and processing when using the contact form

If you use our email contact form when visiting our website to quickly contact us electronically or make an enquiry, the data you provide (surname, first name, email address*, product interest*, enquiry and any other information you provide) will be automatically collected and stored. This personal data transmitted by you on a voluntary basis will only be used for the purpose of processing your enquiry, sending you an offer or contacting you in the event of any follow-up questions.

The legal basis for the processing of this data is Art. 6 para. 1 lit. a GDPR, provided that you have given us your consent to use the data provided in the form. The wording of the consent can be found in the following link

The data transmitted via the contact form will be deleted after final processing of your enquiry, provided that this does not conflict with statutory retention obligations.

Cookies are small text files that are stored on your device when you visit our website. They are used to make our website more user-friendly, effective and secure.

There are different types of cookies. Session cookies are temporary cookies that are stored in the visitor's browser. Session cookies are deleted when the current session is ended or the browser window is closed. Permanent or persistent cookies are saved for repeated visits and are stored in the visitor's browser for a certain period of time.

The use of cookies serves the proper operation of the website, the provision of basic functionalities for the use of the website and the analysis for the customer-friendly and effective design and optimisation of our websites. Our legitimate interest in data processing lies in the aforementioned purposes. The legal basis for the use of cookies is therefore Art. 6 para. 1 lit. f GDPR.

Newsletter software

Brevo (formerly Sendinblue) is used as newsletter software. Your data will be transmitted to Sendinblue GmbH. Brevo is prohibited from selling your data and using it for purposes other than sending newsletters. Brevo is a German provider that has been selected in accordance with the requirements of the General Data Protection Regulation and the Federal Data Protection Act. We have concluded an order processing contract with Brevo, in which we oblige the service provider to protect the data of our newsletter subscribers and not to pass it on to third parties.

Further information can be found here:

The purpose of storing your e-mail address is to be able to send you the newsletter. We store the respective IP address and the times of registration and confirmation in order to be able to prove your registration in a legally compliant manner and, if necessary, to clarify any possible misuse of your personal data. This is also our legitimate interest.

The newsletters we send out contain so-called tracking pixels. A tracking pixel is a miniature graphic that is embedded in our newsletter emails. This allows us to statistically analyse the success or failure of our online marketing campaigns. Using the embedded tracking pixel, we can recognise whether and when a newsletter was opened by the recipient and which links in the email were of interest to the person concerned and were clicked on.

The personal data collected via the tracking pixels contained in the newsletters is stored and analysed by us. Based on this analysis, we can optimise our newsletters accordingly and adapt the content of future newsletters even better to the interests of our newsletter subscribers. This is our legitimate interest in processing this data.

If you have given us your consent, the legal basis for the processing of the data after registration for the newsletter is Art. 6 para. 1 lit. a GDPR. If the processing is based on a legitimate interest on our part, the legal basis is Art. 6 para. 1 lit. f GDPR.

The above data will be deleted as soon as it is no longer required for the purposes mentioned. The data will therefore be stored for as long as you have subscribed to the newsletter.

You can revoke your consent to the storage of the data, the e-mail address and its use for sending the newsletter and analysing the success of the newsletter at any time. There is a corresponding unsubscribe link in every newsletter. You can also inform us of your request at any time using the contact options provided in the privacy policy and on the websites.

Google Fonts (local integration)

We use Google Fonts (selection of fonts for website design) to design our website. In order to display certain fonts on our websites, these fonts are provided locally when our pages are accessed, i.e. there is no connection to Google servers. Further information is available at

Font Awesome (local integration)
We use FontAwesome (icon collection, toolkit for selecting font-based icons for designing websites) to design our website.

Google Tag Manager

We use Google Tag Manager, a service provided by Google Ireland Limited, on our websites. Google Tag Manager is a tag management system that can be used to manage and configure tracking codes for our websites via a web interface. Google Tag Manager records interactions that the user carries out on our websites. These are forwarded to connected analysis tools. It is not possible to analyse the data itself with the Tag Manager. This is done in the respective tool. Google Tag Manager is a cookie-free domain and does not collect any personal data itself. Google Tag Manager triggers other tags, which in turn may collect data. However, Google Tag Manager does not access this data. If a deactivation has been made at domain or cookie level, this remains in place for all tracking tags that are implemented with Google Tag Manager.

Web analysis with Google Analytics

This website uses Google Analytics, a web analytics service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google Analytics uses cookies that are stored on your computer and enable your use of the website to be analysed.

Due to the activation of IP anonymisation on this website, your IP address will be shortened beforehand by Google within member states of the European Union or in other contracting states of the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and truncated there. Google will use this information on behalf of the operator of this website to analyse your use of the website, to compile reports on website activity and to provide the website operator with other services relating to website activity and internet usage. The IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.

The use of Google Analytics on our website serves the purpose of analysing the use of our website and continuously improving its functionality and user-friendliness. This is our legitimate interest in data processing; the legal basis for this is Art. 6 para. 1 lit. f GDPR.

Google Analytics is only used on our website with the described IP anonymisation (IP masking using the code "anonymizeIp"). Your IP address is therefore only processed further in abbreviated form, which means that any personal reference can be ruled out.

The website usage analysis data stored by Google Analytics is automatically deleted after 26 months. Data that has reached the end of its retention period is automatically deleted once a month.

You can prevent the storage of cookies by selecting the appropriate settings in your browser; however, please note that if you do this you may not be able to use the full functionality of this website.
You can also prevent the information collected by cookies (including your IP address) from being sent to Google and used by Google by clicking on the following link and installing the browser plugin available at the following link.

Google Ads conversion tracking

We use the online advertising tool Google Ads on our websites, a service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. As part of Google Ads, we use the conversion tracking analysis service. The purpose of Google Ads is to advertise our website in the search engine results of the Google search engine.

If you reach our website via a Google advert, Google Ads will store cookies on your computer. These cookies for conversion tracking are set when a user clicks on an advert placed by Google. They lose their validity after 30 days and are not used for personal identification. These cookies enable Google to recognise your web browser as long as the stored cookie has not yet expired.

The conversion cookie enables both Google and us as advertisers to determine whether a user has clicked on a Google Ads advert and subsequently visited our websites. It also allows us to track whether a visitor who has reached our website via a Google Ads advert has performed a specific action (target). As the advertiser, we do not collect and process any personal data ourselves, but only receive statistical analyses from Google.

The data and information collected through the use of the conversion cookie is used by Google to compile visitor statistics for our website. These visitor statistics are used by us to determine the total number of users on our website who were referred to us via Google Ads ads and thus to measure and optimise the success of a Google Ads ad. Based on these analyses, we can recognise which of our advertising measures are particularly effective.

We use Google Ads as described above for marketing and optimisation purposes and to determine the efficiency of the advertising measures used. This also constitutes our legitimate interest in the processing of the above data by the third-party provider. The legal basis is Art. 6 para. 1 sentence 1 lit. f) GDPR.

Embedding of YouTube videos

We use embeds (so-called embeds) from the YouTube video portal on our websites. These embeds are inserted on our websites as playback frames via an HTML link provided by YouTube. This playback frame is used to play the video stored on the YouTube platform.
To use these embeds, we have activated the "extended data protection mode" offered by YouTube, which, according to the YouTube platform, means that cookie activity and data collection about website visitors only takes place when the playback function of the video is started.
The display of the respective video requires a connection to the YouTube servers, whereby your IP address and the information about which pages you have visited are transmitted to YouTube. If you call up a YouTube video embedded on this website and are logged into your YouTube account at the same time, you also enable YouTube to link your usage behaviour with your personal profile. You can prevent this by logging out of your personal YouTube account before using the video.
The purpose of embedding YouTube videos on our websites is to make the content of our videos available to you directly on our pages without you having to access them separately on YouTube. This enables us to improve our offering and the user experience on our websites and make it more interesting for you.
Our legitimate interest lies in the aforementioned data processing operations and the aforementioned purposes of processing based on the legal basis of Art. 6 para. 1 lit. f GDPR.
The provider of the YouTube platform is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Further information on data protection at YouTube can be found at the following link

Links to our information pages on social networks

In order to present our company and our products to interested parties, customers and partners, we also use presences on the social networks facebook, LinkedIN, XING, Youtube and Instagram. You will find buttons for these social networks in the footer of our website.

The buttons are labelled with the logo of the respective social network. However, these are not the usual social media plugins (see next section), but buttons with links to our information pages on the respective social network. The buttons are activated by clicking on them. As long as these buttons are not clicked, no data is transmitted to the social networks. Only when you click on the buttons will the connection be established and data transmitted to the social network and used in accordance with its data usage guidelines.

The purpose and scope of the data collection and the further processing and use of the data by the respective social network as well as your rights in this regard and setting options to protect your privacy can be found in the information

Social media buttons (share buttons) on the blog

On our blog, you have the option of sharing blog content via social media buttons (social media plugins or share buttons) on the social networks Facebook, LinkedIn and XING.
To protect the data of our website visitors, we use the Shariff solution from heise to implement the social media buttons on our blog. The Shariff solution prevents the social media buttons from sending user data to the operators of the social networks simply by calling up and visiting the website. Our social media buttons only establish the connection to the social networks when you as a website visitor actively click on one of the share buttons to share content.
When you click, the connection is established and data is transmitted to the social network and used in accordance with its data usage guidelines.
For the purpose and scope of data collection and the further processing and use of the data by the respective social network as well as your rights in this regard and setting options to protect your privacy, please refer to the information

Audio and video conferences (online meetings) with Microsoft teams

The purpose of data processing is to organise telephone conferences, video conferences, online meetings and online presentations or training sessions for interested parties or customers. For this purpose, we use the Microsoft Teams tool, a service provided by Microsoft Corp, 1 Microsoft Way, Redmond, WA 98052, USA.

Various types of data are processed through the use of Microsoft Teams. The scope of data processing also depends on what data is provided before or during use of the tool.

The following personal data may be processed:

  • User details: e.g. display name ("Display name"), e-mail address if applicable, profile picture (optional), preferred language
  • Meeting metadata: e.g. date, time, meeting ID, telephone numbers, location
  • Text, audio and video data: To enable the display of video and playback of audio, data from the end device's microphone and any video camera on the end device is processed for the duration of the meeting. The camera or microphone can be activated or deactivated by the user at any time via the Microsoft Teams settings. If the chat function is used in an online meeting, the text entries made by the respective user are processed in order to display them in the online meeting. It is also possible to display your own screen or share content (e.g. for screen presentations). The screen/content sharing function must be actively started or cancelled by the user.

Further information on the use of personal data by Microsoft can be found at

Data processing may be based on the following legal bases:

  • The legal basis for data processing when conducting online meetings is Art. 6 para. 1 lit. b) GDPR, insofar as the online meetings are conducted in the context of contractual relationships or pre-contractual negotiations.
  • Insofar as no contractual or pre-contractual relationship exists, the legal basis is Art. 6 para. 1 lit. f) GDPR. Our legitimate interest here is the effective organisation of online meetings.
  • For the data processing of personal data of employees, Section 26 BDSG in conjunction with Art. 88 GDPR also forms the legal basis. Art. 88 GDPR forms the legal basis for data processing to establish, implement and terminate the employment relationship.

Personal data that is processed in connection with participation in an online meeting will not be passed on to third parties unless it is intended or authorised to be passed on.

The provider of Microsoft Teams only obtains knowledge of the above-mentioned data to the extent that this is necessary for the provision of the service and is provided for in the order processing contract with Microsoft.

We have concluded an order processing contract with Microsoft for this purpose via the Microsoft Online Service Terms (OST) and the associated Data Protection Addendum (DPA).

Data processing outside the European Union (EU) does not generally take place, as we have restricted the storage location of the data to data centres in Germany. However, this may not apply to telemetry or diagnostic data, the support hotline and any other data that is processed within Microsoft's area of responsibility.

Personal data is generally deleted by us if there is no need for further storage. Storage may be necessary in particular if the data is still required, for example to fulfil contractual services. In the case of statutory retention obligations, deletion will only be considered after the respective retention obligation has expired.

Online appointment booking via Microsoft Bookings (optional)

To book appointments online with our sales team, you have the option of making an online appointment booking in addition to the traditional appointment booking by telephone and email. For this purpose, we use the Microsoft Bookings service of Microsoft Corporation, One Microsoft Way, Redmond, WA 98052-6399, USA.

The connection to this service is only established if you access the online booking function via the link in an email or in the newsletter. Your entries in the appointment booking form are transmitted to Microsoft for the appointment booking. Further information on how your data is handled can be found in the Microsoft privacy policy at

If you request an appointment using the appointment booking form, the data you enter there (e.g. name, e-mail address) and the desired appointment will be recorded in the booking system. After selecting your appointment, confirming it and entering your contact details, you will receive an e-mail confirming your appointment.

The purpose of using the online appointment booking via Microsoft Bookings is to ensure a fast and user-friendly appointment booking option. The legal basis for data processing is your consent in accordance with Art. 6 para. 1 lit. a); consent can be revoked at any time for the future.

We would like to point out that you are not obliged to use Microsoft Bookings to make an appointment. If you do not wish to use the service, please use another of the contact options offered to make an appointment.
