Already use 1Password for my securing my financial data, making it instantly available on a web site, no copy/pasting for multiple fields required. That's about as far as trusting a third-party app for encrypting my stuff! I don't trust computers or the people that program them!
I can always get that financial data from the original sources. Who will provide the key to get my other data when this developer/company goes out of business or someone discovers a bug?!
