It's hard to say if National Grant Secrets is a scam. There are users who say the product is legit and there are other who say it's a big scam meant to take your money in a very legal way. However, this application isn't active anymore which means it's already been discontinued. If you want to get information about grant system for your own needs, I advise you to consult your lawyer. He should be able to provide information about secrets, software and the way this whole system works.
