If you're worried about the safety of your private, then AbsolutePrivacy may be a good solution for you. Behind a rather simple design you have a wide range of apps that enable you to manage your personal and professional life while taking security very seriously.

This program works as a personal information manager, featuring tools like a calendar, a memo app, a contacts manager, a diary and a tool to control your personal budget. The difference with other PIMs is that all the data you enter will be encrypted and protected.

The program's interface is quite plain, but at the same time this makes the program easy to use. No knowledge about encryption needed!
