Cookie Policy

Our website uses so-called cookies. These are small text files that are stored on your device and, among other things, make it possible to recognise your browser the next time you visit and to save the settings you have made. Our website uses essential cookies as well as optional cookies from external service providers for analysis and marketing.

Essential cookies enable basic functions and are necessary for the proper operating of the website. We use such a cookie to remember your cookie banner decision to ensure that you are not shown our cookie banner again each time you visit our website. This cookie is called "omCookieConsent" and is valid for 1 year.

Cookies for analysis and marketing are used to analyse user behaviour on the website and also to optimise advertising campaigns. We use technologies from Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA ("Google") for this purpose.

I. Legal basis for data processing and objection options

The legal basis for processing your data for analysis and marketing is your consent (General Data Protection Regulation "GDPR": Art 6(1)(a)).

If you wish to change the setting you selected via the cookie banner, e.g. revoke your consent to cookies for analysis and marketing, please delete the cookies in your browser, then the cookie banner will reappear when you visit our website again and you can change your setting.

You can also prevent cookies from being stored by setting your browser software accordingly or only allow them in individual cases; you can also activate the automatic deletion of cookies when closing the website. We inform you that if you deactivate cookies, you may not be able to use all the features of our service.

We would like to point out that we have no influence on how Google uses the collected data. According to Google, the data is encrypted and stored on secure servers. Within the scope of these services, data transfer to the USA or other countries cannot be ruled out. You can find more information on data processing by Google in Google's privacy policy:

II. Google Analytics

We use Google Analytics to compile statistics about visits to our website. The information about your use of our website, such as browser type and version, operating system, website previously visited, time, approximate location, pages viewed, including your IP address, is transmitted to a Google server and stored there. Our website uses the IP address anonymisation function for Google Analytics. Your IP address is thereby shortened or anonymised by Google as soon as Google receives your IP address. Your IP address will not be merged with other data by Google. Google uses the information collected to evaluate your use of the website, to compile reports on website activity and to provide other services related to website activity and internet usage.

III. Google Maps

The website uses Google Maps under "Contact" in order to display geographical information. When using Google Maps, Google collects and processes data on the use of the Maps functions by visitors to the website.

IV. Google Tag Manager

We use the Google Tag Manager, a service with which website tags can be managed via an interface. The Tag Manager only forwards data, but does not collect or store it. The Tag Manager is a cookie-less domain and does not process any personal data. It takes care of the resolution of other tags, which themselves may collect data, but does not access this data.

You can find more information about Google Tag Manager here:

V. Google Ads

We use Google Ads (formerly Google AdWords) to advertise our services. To do this, we use conversion tracking from Google. This allows us to see which keywords, ads, ad groups and campaigns lead to customer responses, such as calls or clicks to our contact page. When you click on one of our Google Ads ads, a cookie from a Google domain is stored on your device. Google recognises the cookie and saves your action on our website as a so-called conversion. This data allows us to measure the success of individual ads and optimise our online marketing measures.

VI. Cookies for analysis and marketing and their storage period

"_ga", the main cookie used by Google Analytics, allows a service to distinguish one user from another and persists for 2 years. Cookies starting with "_gac_" are used to measure user activity and the performance of advertising campaigns, the storage period is 90 days. Other cookies set are mostly only valid for 1 minute to 24 hours.

The earlier version of Google Analytics (Classic Analytics) sets cookies with "__utm". For example, "__utma" contains a randomly generated user ID that Google can use to merge data from previous visits by returning users. "__utmz" records from which other website or from which advertisement a visitor came to the page. Other cookies with "__utm" are valid for between 10 minutes and 2 years.

The cookie "test_cookie" does not contain any identification features and is set as a test to check whether the browser allows cookies to be set. It is valid for 15 minutes.

The most important cookies for Google Ads, "IDE", "NID", "ANID", "__gads", are used to display Google advertisements. The storage period is between 6 and 24 months. "IDE" contains a randomly generated user ID that Google can use to recognise users across different websites and display personalised ads. If you have disabled personalized advertising, the "ANID" cookie is used to save this setting until 2030. Other cookies are used to measure conversions, e.g. "Conversion" and "_gcl_" remain for 90 days. Targeting cookies, such as "__Secure-3PSIDCC", "__Secure-3PSID" and "__Secure-3PAPISID" with a validity of 2 years are set to display relevant and personalised Google Ads.

Google cookies are partly set by the 3rd party domain A list of cookies set by Google can be found here:
