We use the Google service reCaptcha to determine whether a person or a computer makes a specific entry in our contact or newsletter form. Google uses the following information to determine if you are a human being or a computer: IP address of the terminal device you are using, the website you are visiting and on which the captcha is integrated, the date and duration of the visit, the identification 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 for which you must identify images. The legal basis for the described data processing is Art. 6 para. 1 lit. f 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 input (attacks).
