How to make a Cordova application unusable on web browsers?

I have a very simple question, is there anyway to keep people away from the possibilty of running my Cordova application in a web browser?. I mean, that in case that someone success in getting access to the www/ source code folder they would not be able to run it in their web browser.

I heard about cordova-plugin-crypt-file, does it work?, what are you experiences with it?, thanks a lot.
