You supply this key? So you are implying that you store the key and the company doesn't have access to it, hence doesn't have access to your data? Then is there any reason for the company to store your data? What if you loose the key? You can't restore your account? I'd be interested to know the % of users loosing their password and needing to use "forgot password" feature. How would that work with a key you own?
