Efficient Diary is an elegant, easy-to-use and powerful electronic diary program.
With its unique and powerful flash full-text search technique, you can simply enter a word in the diary to quickly find the corresponding entries.
The login password is encrypted by the irreversible algorithm of SHA; besides, the content of the file itself is encrypted so that your private information is fully protected.
Doesn't look like this app is available anymore - the efficientdiary.com site is now a parked domain.
I have been a user of this software for many years. I find it to be the best of this type of software in terms of reliability.
