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. To use Tails, shut down the computer and start on your Tails USB stick instead of starting on Windows, macOS, or Linux.
Tails is a 1.2 GB download and takes approximately 30 minutes to install. Tails can be installed on any USB stick of 8 GB minimum. Tails works on most computers less than 10 years old.
