Hi Alice,
I use MS OneNote for journaling. (I don't journal a lot but it's great when I have.) It's great...you can tailor it to your needs (there's probably journaling templates available on Microsoft.com). You can password protect it if you want and it's automatically saved all of the time. The best thing is that you can use the software for a lot of other things as well. Keeping notes, using them as notebooks for each client, etc. It's a really wonderful piece of software

You might be able to get a 30-day free trial at Microsoft.
Warmly,
Susan
