I would also very much like to see encrypted notebooks (as I have mentioned before in other threads), but only if they are "zero knowledge" like SpiderOak (only I have the encryption key), and only if they encrypt the data on Evernote's servers. As BNF said, this has been discussed a lot on the forums already, and so far, Evernote has resisted the idea. It does (as BNF said) run counter to the design philosophy of Evernote, so I think I can see where they are coming from. However, we live in the world we live in, and speaking for myself, I would prefer to trade convenience for privacy/security. For now, I am very selective about what I put on the cloud (http://www.christopher-mayo.com/?p=288) -- even more in recent days (I'll stay away from anything overtly political here except to say that I am dismayed by some of the things that have been said by some people in positions of influence about the level of privacy they think we ought to have). I have not used MacFort. My guess is that MacFort encrypts the Evernote files on your hard drive only. Presumably, this would protect you from relatives or friends who use your computer. In my case, I just set up a separate user profile and use FileVault, so my data is about as secure as it is going to get. If you are looking for "password protection" on your account because you share your computer, I'd strongly recommend what you already have for free on your Mac, because it is quite powerful protection. Thanks for your detailed explanation. I'm not concerned about the data safety in the cloud. I choose Evernote because i believe the company will take care of my data. I'd like to password protect Evernote because i share my iMac with my sister. FileVault is overkill for me, i just want to encrypt Evernote notebooks on my computer, not the whole hard disk, and i don't want to log out when my sister just need to use my computer for a while... Anyway, i will appreciate if Evernote can give me the ability to password lock the app itself..
