Be Aware - what you enter is not protected.
This program was designed for a single user on a dedicated computer.
While your password is usually not recognizable, it is not encrypted and at this point anyone can down-load your file and tinker with it. Your Email address is morphed into a file name with no separate UserID and hobbyists might pick yours to down-load and then puzzle it out.

This is a temporary situation - if there is significant interest in the algorithm, it is quite possible to re-write the program using the mySQL database. However, right now it is a hobby-project.

In practical terms that means your journal entries should not include anything you don't want others to find out should they poke around the site, and it is best to make sure there is nothing in the file that would identify you.
