Palm security

I find myself storing a pile of vaugely sensitive information on my palm. Where do I find the competent analysis of this? Ideally, I'd like to be able to protect things that I move into a "sensitive" area (passwords), and maybe select items in other places that I want to encrypt. I don't really want to have to enter a password each time I look at my schedule and todo lists. Someone suggested YAPS (http://www.palmblvd.com/software/pc/Yaps-2000-11-7-palm-pc.html) are there others I should look at?
