This is a diary. It's oldschool because it has a textmode-like interface, so nothing fancy or colourful will distract you. Uses MD5/Rijndael128 for encryption.
It is pretty alpha, but should be stable enough for basic everyday use, I've been using it for over a year now without any problems.
For more information read the readme.txt in the archive.
