You might also want to have some more proofreading done. I cought this "[..]Nat get's a good[..]" 5 seconds into your page
I strongly disagree with your tag line. I think the only way such note taking should be is open source and completely private, otherwise a) you're locked in and b) you risk sensitive info leaking.

We've decided to focus on the ease of use but there are of course many other note takings apps focusing on the other side :)
