Google Services

We use Google services on our website. The operator is Google Ireland Ltd., Gordon House, Barrow Street, Dublin 4, Ireland (hereinafter referred to as "Google").

When Google services are used, the data collected may be transmitted, stored and used by Google and other group companies in the USA – including but not limited to Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA (hereinafter also referred to as "Google"). This entails the risk, for example, that your data may be subject to extensive access by security authorities.

Third country transfer: Where data is processed outside the EU/EEA and there is no level of data protection corresponding to the European standard, we have agreed EU standard contractual clauses [https://business.safety.google/adsprocessorterms/sccs/eu-c2p/] with the service provider to establish an appropriate level of data protection. The parent company of Google Ireland, Google LLC, is based in California, USA. A transfer of data to the USA and access by US authorities to the data stored by Google cannot be ruled out. The USA is currently considered a third country from a data protection perspective, and you do not have the same rights there as within the EU/EEA. You may not have any legal remedies against access by authorities.

Google Analytics

Currently our collaboration with Google in relation to the components “Google Analytics 4” and “Google Tag Manager”, which are described in more detail below, is based on the contract for commissioned processing provided by Google pursuant to Article 28 of the GDPR (available at: https://privacy.google.com/businesses/processorterms/). Within the scope of this agreement, Google is entitled to engage subcontractors. A list of these subcontractors is available at  https://privacy.google.com/businesses/subprocessors/.

Scope of processing: Google Analytics 4 uses cookies to help analyse how you use our web pages. The information collected by means of the cookies about your use of this website is generally transferred to a Google server in the USA and stored there.

For Google Analytics 4, the pseudonymisation of IP addresses is activated by default. Due to IP pseudonymisation, your IP address will be shortened 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 shortened there. According to Google, the IP address transmitted by your browser as part of Google Analytics will not be merged with other Google data.

During your website visit, your user behaviour is recorded in the form of "events". Events can be: Page views, first visit and repeat visits to the website, start of session, your "click path" - interaction with the website, scrolls to the end of the page, clicks on external links, internal search queries, interaction with videos, file downloads, language settings.

The following is also recorded: Your approximate location, your IP address in shortened form, technical information about your browser and the terminal devices you use, your internet service provider, the referrer URL. 

Processing purposes: On behalf of the operator of this website, Google will use this information for the purpose of evaluating your use of the website, and compiling reports on website activity. The reports provided by Google Analytics are used to analyse the performance of our website and the success of our marketing campaigns (conversion measurement).

The purpose of the Google Analytics components is our legitimate interest in analysing the flows of visitors to our website and measuring its reach (purpose pursuant to Article 6.1 (f) of the GDPR). The use of Google Analytics also takes place on the basis of your express consent (Article 6.1 (a) of the GDPR). The granting of consent is voluntary. You can revoke your consent at any time in the cookie settings. The lawfulness of any processing carried out on the basis of consent before such revocation remains unaffected.

Google Analytics places statistics cookies on your computer. Please refer to the section on “Cookies” below for more information about cookies. The cookies allow the use of our website to be analysed. Each time you visit one of the pages of this website, the Internet browser on your computer is automatically prompted by the relevant Google Analytics component to transmit data to Google for the purpose of online analysis.

Such revocation shall be without prejudice to the lawfulness of the data processing carried out on the basis of the consent up until the revocation thereof.

Google Tag Manager

We also use the Google service “Google Tag Manager”.

Google Tag Manager allows us to manage the analytics tools (such as Google Analytics 4) via one standardised application. The Tag Manager manages the so-called tags assigned to the respective analytics tool. Tags are code elements that are built into the source text of our website for the use of tracking and analysis tools such as Google Analytics 4. With the help of the Google Tag Manager, we are able to manage the tags required for use of the tracking and analytics tools in a uniform manner and thus to save computing and programming power.

If and to the extent that personal data is processed via the Google Tag Manager, this processing is based on our legitimate interest in the efficient management of tags/analytics tools used by us (Article 6.1 (f) of the GDPR).

Further information on the Google Tag Manager can be found on the following Google web pages: Terms of use: https://marketingplatform.google.com/about/analytics/tag-manager/use-policy/ and FAQs: https://support.google.com/tagmanager/?hl=en-GB&sjid=9337105605838087469-EU#topic=3441647

A particular Internet browser can be recognised and identified by its unique cookie ID.
