Tails is Free Software: you can download, use, and share it with no restrictions.

Tails is released under the GNU/GPL (version 3 or above).

However, Tails includes non-free firmware in order to work on as much hardware as possible.

Distribution of the source code

Most of the software distributed with Tails is taken directly from upstream Debian packages, and is not modified or recompiled by Tails. Software that is modified or recompiled by Tails are available in our git repositories. If you require or desire the sources for unmodified Debian upstream packages, retrieving them from Debian is the simplest solution for all parties (packages that can not be found in the regular Debian archive anymore can be found at http://snapshot.debian.org/).

According to the GPL licence (section 3(b) of the GPLv2 and section 6(b) of the GPLv3), complete sources for all Tails releases are available for anyone who requests them, in DVD format, via postal mail, for a nominal charge. If you only require one or two source packages, Tails can work with you to send a copy of individual packages electronically.
