The description of Tor Tails - Play With New Friends
Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly.
Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis.
It is a complete operating system designed to be used from a DVD, USB stick, or SD card independently of the computer's original operating system. It is Free Software and based on Debian GNU/Linux.
Tails comes with several built-in applications pre-configured with security in mind: web browser, instant messaging client, email client, office suite, image and sound editor, etc.
Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location.
Tails is configured with special care to not use the computer's hard-disks, even if there is some swap space on them. The only storage space used by Tails is the RAM, which is automatically erased when the computer shuts down. So you won't leave any trace neither of the Tails system nor of what you did on the computer. That's why we call it "amnesic".
This allows you to work on sensitive documents on any computer and protect you from data recovery after shutdown. Of course, you can still explicitly save some documents to another USB or external hard-disk and take them away for future use.
