Tails live OS, Privacy for anyone anywhere

 

Tails is a live operating system that you can start on almost any computer from a USB stick or a DVD.

It aims at preserving your privacy and anonymity, and helps you to:

  • use the Internet anonymously and circumvent censorship;
    all connections to the Internet are forced to go through the Tor network;
  • leave no trace on the computer you are using unless you ask it explicitly;
  • use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging.

Online anonymity and censorship circumvention

Tor

Tails relies on the Tor anonymity network to protect your privacy online:

  • all software is configured to connect to the Internet through Tor
  • if an application tries to connect to the Internet directly, the connection is automatically blocked for security.

Tor is an open and distributed network that helps defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security.

Tor protects you by bouncing your communications around a 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.

Using Tor you can:

  • be anonymous online by hiding your location,
  • connect to services that would be censored otherwise;
  • resist attacks that block the usage of Tor using circumvention tools such as bridges.

To learn more about Tor, see the official Tor website, particularly the following pages:

Use anywhere but leave no trace

Using Tails on a computer doesn’t alter or depend on the operating system installed on it. So you can use it in the same way on your computer, a friend’s computer, or one at your local library. After shutting down Tails, the computer will start again with its usual operating system.

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 in RAM, which is automatically erased when the computer shuts down. So you won’t leave any trace on the computer either of the Tails system itself or what you used it for. That’s why we call Tails “amnesic”.

This allows you to work with sensitive documents on any computer and protects you from data recovery after shutdown. Of course, you can still explicitly save specific documents to another USB stick or external hard-disk and take them away for future use.

State-of-the-art cryptographic tools

Tails also comes with a selection of tools to protect your data using strong encryption:
