The Amnesic Incognito Live System (Tails) is a Debian based live CD/USB aimed at preserving your privacy and anonymity by forcing all outgoing connections to the Internet to go through the Tor network and by leaving no trace on local storage devices unless explicitly asked. Tails 0.7, based on Debian 6.0 squeeze, was released April 15, 2011. Debian 9 (stretch)-based Tails 3.8 was released June 26, 2018.
