This is the fundamental problem for any cloud services. You don't know if a small company like Evernote is going to go bust, too, and many have, sometimes bought to kill by Google and its ilk. So it's no safer than using large company products. And if not Evernote, some other service you once used, like say delicious. Or they don't update it as fast, and it gets clunky, like flickr (not coincidentally both bought and ruined by yahoo) For real security of data and use: either 1. Download and install with local storage only 2. whatever service you do use, save all the things locally frequently, in multiple open data formats.
