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.

The live session is powered by a traditional GNOME desktop environment bundled with well known open source applications, such as Apache OpenOffice, Iceweasel web browser, Claws Mail email client, Liferea feed reader, Pidgin instant messenger, GIMP image editor, Inkscape SVG graphics editor, Audacity audio editor, PiTiVi video editor, and Synaptic Package Manager.

Users will be greeted by a welcome message that allows them to login into the live session or change various other options, such as to add a root (system administrator) password, camouflage the system to look like a Windows XP machine, as well as to spoof all MAC addresses. The live session is powered by a traditional GNOME desktop environment bundled with well known open source applications, such as Apache OpenOffice, Iceweasel web browser, Claws Mail email client, Liferea feed reader, Pidgin instant messenger, GIMP image editor, Inkscape SVG graphics editor, Audacity audio editor, PiTiVi video editor, and Synaptic Package Manager.

The boot medium comes with only two options, to start the live environment with default settings or in failsafe mode (just in case the first option won’t work for you). Pressing Enter on the first option will start the live environment.

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.

Tails 2.11 will be the last version to include I2P, an alternative anonymizing network.

Maintaining software like I2P well-integrated in Tails takes time and effort and our team is too busy with other priorities. Unfortunately, we failed to find a developer outside of our team to maintain I2P in Tails. As a consequence, the last version of I2P being shipped in Tails is 0.9.25, which is nearly one year old now at this moment.
