I immediately know what you mean since I was born and raised in the US, but most people will be left scratching their heads unless they're really well versed in the historical legislation of other countries. (I consider myself fairly well versed in international relations, but if someone made an app referring to a specific UK Act of Parliament I'd be confused.) But I agree, Felony isn't the best name.
It would make me unwilling to use it, due to being clearly pro-American. While it's the american government that is most likely to be spying on me. Awful name, felony is better.
I'm sorry but as a non-US person it's been made very clear to me that I have zero rights, zero laws to depend on and zero expectations of privacy. Calling it "the fourth" is like rubbing that in my face, leaving a rather bad taste.
