Hi, this issue was already posted in 2017 https://krpano.com/forum/wbb/inde…&threadID=15629 but was never addressed, or maybe I did not find any info on that.
So I'm developing a plugin, that on top of free functionality, will have some additional features for a fee. I'm looking for an option, to verify if user (krpano viewer) is entitled to that paid functionality.
And it doesn't need to be readable (like to trace or copy to variable), just need a way to compare it with variable in plugin.
Is there a way to do that? If not, what are other ways of protecting paid plugins?
