Cookies & privacy
We set necessary cookies for sign-in and security — the portal does not work without them. On the map pages your browser also loads map tiles from external providers, and we only load the Google fonts if you agree.
There is no tracking, no advertising and no audience measurement here.
The session cookie keeps you signed in, a second value protects forms against misuse (CSRF), and a login cookie is added only if you tick “Stay signed in”. Without these cookies there would be no members' area, so they cannot be switched off.
Map tiles: The maps fetch their image tiles from OpenStreetMap/CARTO and Esri; each provider learns your IP address in the process. There is no switch for this because the map would simply stay empty — it only concerns the map pages.
Your browser remembers locally (localStorage) which radar layers you had switched on and which notices you dismissed. This information never leaves your device and goes to nobody.
The fonts Outfit and Bebas Neue are hosted by Google. If they are loaded, your browser sends your IP address to Google in the USA. Without your consent we use the fonts of your system — the page then looks slightly different, but works in full.
