Privacy for anyone anywhere

Tails is a <a href="https://en.wikipedia.org/wiki/Live%5FUSB" target="_blank" rel="nofollow noopener noreferrer">Live%5Fusb</a>, that you can start on almost any computer from a DVD, USB stick, or SD card. 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 <a href="https://www.torproject.org/" target="_blank" rel="nofollow noopener noreferrer">Tor Project | Anonymity Online</a>;
• 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.
