Cire is a free and open-source program designed for keeping an electronic journal or diary, which runs on Linux and other unixes. It is potentially useful for any sort of situation which requires the ability to maintain organized, chronological and encrypted logs or notes. Cire also provides a choice between three different forms of interfaces: a full GTK graphical interface, a command-line ncurses interface, and a simple command-line text interface.

Cire is licensed under the GNU General Public License, and can thus be changed and customized in any way permitted by the GPL (a copy of which can be viewed by clicking on "License" on the left). While active development of Cire ceased in 2004, it will continue to be made available under these terms to anyone who may find it useful.
