Re: The Shadow Defender Challenge. The concern I would feel given the first portion of your quote (above) would give me strong suspicions regarding the second part. I have no personal information and certainly find the app interesting but I would hesitate to spend money with a company that apparently lurks in the shadows while revealing nothing about themselves. Perhaps it's my law enforcement background but I don't think you need to have been a "fed" to smell something fishy about the situation. Full disclosure (especially when it comes to "security apps") should be standard practice.
