Not sure if this would work for you or not but I was looking for something similar. My work around was to use aNote app on iPad. I can lock specific folders that then sync with Evernote. I password locked Evernote on my iPad so if someone does need to get to my Evernote notes I let them access it thru aNote not the Evernote app on the iPad. But I do really wish that the locked folders in aNote would automatically be locked folders in Evernote that way they would also be locked on the desktop or web. I will also add that I don't share my iPad with my family. Im actually very protective of it and really do not like any one else using it. I have used the encrypting text for some things but it really is not practical for "journal" like note. I realize that Evernote isn't really intended to be used as journal but it actually works very well for me.
