If you do not want your data to be tracked and processed in Google Analytics, you can install a browser add-on to deactivate Google Analytics, which you can download and install here: https://tools.google.com/dlpage/gaoptout/. If you do not wish to or cannot install this add-on (e.g. on mobile devices), you can alternatively use this link (https://developers.google.com/analytics/devguides/collection/gajs/?hl=de#disable) to set an opt-out cookie that will prevent Google Analytics from collecting your data in the future when you visit our website.
