Do you encrypt data? If your servers are compromised, will someone have access to all of my emails? Even if that is the case, I might be more comfortable using Greplin if I knew more about your security practices. What procedures are in place to prevent my emails from being stolen? Edit: I hate being the one to criticize an incredible idea that is the result of hard work. I feel obligated to add that I want to use Greplin and I probably will use it for Facebook and Twitter. (Facebook's built-in search is useless.) I really hope there is a way that I can use this for email too.
