yes it is. without actual system I had around 85% users who use only stolen app, so I want to do something with this. And best solution is working licence check ...
Could you force it to do a license check any time someone
successfully accesses online maps, WMS services, etc (it would have to be "successfully", of course)? If someone can download an online map tile they clearly have internet access of some sort. This wouldn't stop someone from using Locus completely offline, but it would at least cripple the capabilities for pirated copies.
