BleachBit is a free open source cross platform privacy cleaner, it works in Windows as well as Linux supporting CentOS, Debian, Fedora, OpenSUSE and it even has a NetBSD port.
BleachBit is multilingual, up to this date, it has been translated to thirty seven languages, including Chinese, Tamil, Japanese, Hebrew and Indonesian.

Free privacy cleaner BleachBit bad stuff
I was using the portable version of BleachBit, version 0.8.0, presumably you might want to use this privacy cleaner at an Internet cafe or library but by default BleachBit connects to the Internet to check for updates every time you start it, this might indicate to a computer administrator looking at the logs of visited sites that you are using privacy software to delete your Internet tracks, you can disabled BleachBit automatic updates from the settings, which in my opinion should be disabled for the portable edition.
Another downside I found with BleachBit privacy cleaner portable version, is that help is only available online it would be much better if this could be read where the privacy software is installed.
Free privacy cleaner BleachBit conclusion
Besides being free, BleachBit does a good job at erasing your computer tracks, I found the customization settings a little poor and I did not like having to read the help manual online insted of being included with the download.
I would be very happy using BleachBit in its portable edition for deleting my computer tracks after using a public computer. You can find paid for privacy cleaners that are better than BleachBit desktop version, I think that CyberScrub has more features and customization, but if you want something free, or something portable and cross platform, then BleachBit computer privacy cleaner will meet your needs.
