Privacy

The data controller for this site is Matthias Maier, contact above.

Your routes stay in your browser. Saved lines and points are kept in this browser's local storage, up to 4 MB, and are never sent to OpenTurkart. The site asks the browser to keep this storage. Clearing the site data in your browser deletes them, so export the routes you want to keep as GPX.

Hosting. OpenTurkart is hosted on Cloudflare Pages. Cloudflare receives your IP address and the files your browser requests, and may log them under its own retention rules. Cloudflare, Inc. (USA) does this under its Data Processing Addendum.

Map and data services. Your browser loads the map, the overlays, elevations and place names directly from Kartverket (cache.kartverket.no, wms.geonorge.no, ws.geonorge.no, api.kartverket.no) and the avalanche terrain slope map from NVE (kart.nve.no). These services receive your IP address, the map areas and positions your browser asks for, and your search words. Kartverket and NVE are responsible for their own processing of these requests.

Statistics. If you choose Allow, the site loads Cloudflare Web Analytics, which reports to Cloudflare the page you open, its load time and performance, the site you came from, and your browser, operating system and device type. Cloudflare receives your IP address with each report and uses it to find your country. It sets no cookies. Cloudflare keeps the full reports for 7 days and a sample of them for up to 6 months. If you choose Don't Allow, no statistics script is loaded. Your choice is kept in this browser's local storage, and you can change it at any time:

Your rights. You can ask for access to, correction or deletion of personal data about you, object to processing based on legitimate interest, and withdraw your consent at any time without affecting earlier processing.
