Tension Software (http://pomola.com/products_privatecontact/privatecontact.html) has updated Private Contact, a native Cocoa software to manage an address book in an encrypted form in Mac OS X (10.4 and higher), to version 2.4. The upgrade boasts an improved main window layout, a simplified interface, improved category dialog, embedded PDF user guide and more.

Private Contact uses the powerful Blowfish algorithm to encrypt data. It’s Universal Binary so runs natively on both PowerPC and Intel Macs.
Private Contact can be purchased for US$25. Version 2.4 is a free update to registered users of version 2.x.
