3.2      Google Tag Manager

We use the “Google Tag Manager” provided by Google Ireland Ltd., Gordon House, Barrow Street, Dublin 4, Ireland. This service allows website tags to be managed through an interface. The Google Tag Manager only implements tags. This means that no cookies are used and no personal data is stored. The Google Tag Manager triggers other tags, which in turn collect data if necessary. However, the Google Tag Manager does not access this data. If a deactivation has been made at domain or cookie level, it remains valid for all tracking tags if they are implemented with the Google Tag Manager.

3.3      Google Fonts

(1) We use “Google Web Fonts” on our website, a service provided by Google Ireland Ltd., Google House, Barrow Street, Dublin 4, Ireland. Google Web Fonts enables us to use external fonts, so-called Google Fonts. For this purpose, the required Google Font is loaded into the browser cache by your web browser when you call up our website. This is necessary so that your browser can display a visually improved representation of our texts. If your browser does not support this function, a standard font will be used by your computer for display. The integration of these web fonts takes place via a server call, usually at a Google server in the USA. This transmits to the server which of our Internet pages you have visited. The IP address of your browser is also stored by Google. We have no influence on the scope and further use of the data collected and processed by Google through the use of Google Web Fonts.
