On the other hand there are people (like myself) who are privacy focused, and the first alarm bell is who the heck are these people? They're a random company I've never heard of, hosting free software which I can (and do) host myself and offering to store all of my private, personal and/or important information for me.
Although they may very well be perfectly legitimate and caring people, how do you know their goal isn't to get as many people's data as possible and sell it off to <insert your worst nightmare here>?
This is the issue with the brand recognition problem, and I'm not sure what that target audience is that you fit into.
