There are multiple components to mapping: 1) the data , 2) the tile server, and 3) geolocation. While using the data is not restricted, using the built in tile servers do normally have restrictions.
For example, Tile usage policy - OpenStreetMap Wiki
- Heavy use (e.g. distributing an app that uses tiles from openstreetmap.org) is forbidden without prior permission from the System Administrators. See below for alternatives.
So the question remains, what are the terms and conditions for using mapping in Qlik Sense? I suspect that this is a question that Qlik is going to have to answer. Did Qlik enter into a special agreement for Qlik Sense users to use the tile servers without having to get their own license?
