Map Tools FAQ

Do these tools upload my data?

No. Tool calculations and geographic file processing happen locally in your browser.

Can I use them on a phone?

Yes. Controls stack around a touch-friendly map, and numeric coordinate entry is available as an alternative to map clicks.

Are interactive maps fully offline?

No. Coordinates, calculations, drawings, and files stay local, but visual tiles are downloaded from the displayed external provider.
