Tension Software has released Private Contact 2.0, upgrading the secure contact data software with a new interface and bug fixes. The software stores data inside the user's Address Book, with password protection via Blowfish algorithms. Version 2.0 uses new color categories to aid its sorting and filtering options, and adds many small improvements and fixes.

The software features fast encryption when saving information and decryption when recalling contact info; the company claims that its use of Blowfish encryption is unbreakable in case of computer theft or hacking. Private Contact 2.0 requires Mac OS X 10.4 or higher, but is optimized for Mac OS X 10.5 or later. It costs $25 and is available now for download.
