You decide which optional data processing to allow.
Our anonymous reach measurement runs without cookies and without IP storage, including campaign parameters in links – we do not ask for consent for it because none is legally required.
Strictly required: language preference, core site functions and storing your cookie choice. Without these the site does not work. Settings you choose yourself (light/dark appearance, accessibility) are kept in your browser's local storage only once you choose them; "Reset" in the accessibility settings removes them.
Records your interactions (clicks, scrolling, inputs) pseudonymously so we can spot usability issues. Form field inputs are masked automatically before storage; your IP address is not saved with the recording. Served from our own domain, no external tool. Opt-in, revocable any time.
