Looking for daily journal app with REAL encryption option

Aloha to all. I did a search on the forum and a Google search and didn't find/confirm my answer. I'm looking for a daily journal app that will encrypt my entries securely. Password protect is worthless without encryption. I've found one app called myDAY Journal that says encryption in its description but it doesn't say what kind of encryption. It also mentions password protected but what I figured that means is that you couldn't open the app without a password but is the journal file still protected/encrypted. Anyone one else here is using this journal app or may suggest a good journal app that actually encrypts the journal file? Mahalo in advance!

 

Got an answer from the dev of myDAY Journal and he says that this app does encrypt all entries. on top of being passcode protected. I tried the demo version and I was hooked. This is much better than the one I used to use (Diario).
