What we collect

The calculators run in your browser. Numbers you type and shapes you draw are not sent to our servers. If you use “Copy share link”, the shape’s coordinates are stored only in the link itself.

Third-party services

• Map tiles are loaded from Esri and OpenStreetMap, which receive your IP address and the map area being viewed, as with any web map.
• Location search sends your search text to OpenStreetMap Nominatim to find the place.
• Analytics: we may use privacy-focused, cookie-less analytics (Cloudflare Web Analytics) to count page views.
• Advertising: we may show ads from Google AdSense. Google and its partners may use cookies to serve ads based on your visits to this and other websites. You can opt out of personalized advertising at Google Ads Settings or aboutads.info.
