Site that encrypts Google Docs before they are uploaded so the NSA can't see them

In light of the recent NSA leaks, my friend and I created a website called Fogpad that allows you to create encrypted Google Docs. Everything syncs seamlessly with your Drive, so you don't have to create a new account. It's super easy to use, and free for your first 10 docs. We'd really appreciate it if you checked us out at https://www.fogpad.net.
