Privacy is a companies that keeps your credit card information and purchase records private. Often times I've thought about how my information is kept on every server that I purchase products online, but it seemed impossible to avoid. Privacy fixes that by creating cards you can use for certain purchases with other information, but it's still tied to your work or personal card. So the places you buy from won't have your real information. That's genius! they even offer a pretty usable free plan with some limitations that for a small business may not be too hard to work with.
