General

What browser should I use?

No. All data is stored locally in your browser’s IndexedDB. Nothing is sent to any server.

Can I use Kirra offline?

How do I switch between 2D and 3D?

Use the 2D/3D toggle or the view buttons in the toolbar.

My coordinates look wrong — what coordinate system does Kirra use?

Kirra uses UTM-style real-world coordinates (X=East, Y=North, Z=Elevation). See Coordinate System.
