We use the Google service reCaptcha to determine whether a human or a computer is making a certain entry in our contact or newsletter form. Google uses the following data to check whether you are a human or a computer: IP address of the terminal device used, the website that you visit with us and on which the captcha is embedded, the date and duration of the visit, the recognition data of the browser and operating system type used, Google account if you are logged in to Google, mouse movements on the reCaptcha areas and tasks that require you to identify images. The legal basis for the data processing described is Art. 6 (1) lit. f of the General Data Protection Regulation. There is a legitimate interest on our part in this data processing to ensure the security of our website and to protect us from automated entries (attacks).
