Spot data comes from OpenStreetMap and is licensed under the Open Database License (ODbL 1.0). Every spot imported from OpenStreetMap links back to the object it came from, so the provenance of a pitch stays checkable.
ODbL is a share-alike licence. Extract the spot data from Natrix, change it, publish the result, and you have to publish it under ODbL 1.0 as well, with the same credit to OpenStreetMap contributors.
Map tiles and the map style come from OpenFreeMap, built on OpenMapTiles schemas over OpenStreetMap data. The tiles are fetched by your browser directly from tiles.openfreemap.org.
Address lookups use Nominatim, operated by the OpenStreetMap Foundation. Requests go out from our server at no more than one per second and the answers are cached here, which is what the Nominatim usage policy asks for.
The map itself is drawn by MapLibre GL JS, a BSD-licensed fork of Mapbox GL JS. Icons come from Lucide, licensed ISC.
