Essential to make the site work: your login, language choice, form security (CSRF), basic map tiles (OpenStreetMap, OpenSeaMap, RWS water/depth, Open-Meteo weather) and the typeface of our house style (Google Fonts). No tracking cookies. We also measure the page loading speed anonymously here (RUM): purely speed figures to our own server, without a cookie, without an IP address and without any personal data, so we can track down a slow page.
