The one exception is that to view tile maps which use tiles from the Mapbox service (which is optional, as you can use other tile servers), you will need to have a Mapbox token.

The one exception is that to view tile maps which use tiles from a cloud-hosted service, such as Open Street Maps or Mapbox, you will need a connection to that service. You can view tile maps totally offline if you run your own local tile server and use its tiles.
