Privacy
Kartheim is a private, non-commercial project run by Eirik Midtun. Kartheim has no accounts, ads or tracking.
Your browser remembers your last map view locally, so the map opens where you left off. If you pick a language other than your browser's, a cookie remembers that choice for one year. Neither is shared with anyone. If you tap “My location”, your position is used only in your browser to centre the map. It is not sent to Kartheim and is not stored.
Map images are loaded from OpenFreeMap and Mapterhorn, which therefore see your IP address. The site is hosted by Vercel, which keeps technical logs with IP addresses for a short period. Searches go through Kartheim's server and are not stored.
Questions can be sent through the contact page. You can also complain to the Norwegian Data Protection Authority, Datatilsynet.
