To improve interaction with our visitors, we use a Java Script plugin from uptain GmbH ("uptain plugin" https://www.uptain.de ). This allows us to analyze your use of the website and improve the way you address customers (e.g. through a dialog window). To do this, we collect information about your usage behavior, i.e. movement of the cursor, length of stay, links clicked and any information provided. The legal basis for the processing is our legitimate interest in direct marketing and the provision of our website (Art. 6 Para. 1 lit f GDPR). As a processor, uptain GmbH is strictly bound by our instructions. The information collected will not be passed on to third parties unless we are legally obliged to do so. If the information collected by the uptain plugin contains personal data, this will be deleted immediately after you visit our website.
