Tails will never try to harm you or any of our users, as a core principle of our [[Ssocial Ccontract|about](https://community.torproject.org/policies/social_contract]]/). As part of that commitment, we have written this page to help you make an informed decision about whether you can trust Tails.

Tails will never try to harm you or any of our users, as a core principle of our [social contract](https://community.torproject.org/policies/social_contract/). As part of that commitment, we have written this page to help you make an informed decision about whether you can trust Tails.

We think that Tails is a trustworthy project because:

- **Our work is public**

Tails is [[Free Software|about/license]] and security researchers can examine our [[!tails_gitlab tails/tails desc="source code"]].

Known issues in Tails are described publicly in our [[!tails_gitlab tails/tails/-/issues desc="GitLab issue tracker"]]. We might hide embargoed security vulnerabilities in Tails while we work on a solution, but only as a way of protecting our users.

The most sensitive parts of Tails are explained in our [[design documents|contribute/design]].

- **Tails is based on Tor and Debian**

Most of tThe software included in Tails has not beenis either written by us, but is
or inherited from Tor and Debian
Debian and other Tor projects:

The software included in Tails is either written by us or inherited from
Debian and other Tor projects:

[Debian](https://debian.org/) is the Linux distribution with the most derivatives, including Ubuntu.

Debian and its derivatives
are [the most popular Linux distributions on web
servers](https://w3techs.com/technologies/details/os-linux) across the
Internet.

The Debian project is coordinated over the Internet by a team of
volunteers whose work is entirely public. All this makes Debian one of the
Free Software projects under the most scrutiny by security researchers.

[Tor](https://torproject.org/) is the best anonymity network available.

Tails is made by the Tor Project, the same organization that makes the Tor
software and *Tor Browser*.

[Tor](https://torproject.org/) is the best anonymity network available. Tor Tor
has partnered with leading research institutions and has been subjected to
intensive academic research. Tor has received awards from institutions
such as the [EFF](https://www.eff.org/awards/pioneer/2012) and the [Free
Software
Foundation](https://www.fsf.org/news/2010-free-software-awards-announced).
Even the NSA qualified Tor as "[the King of high secure, low latency Internet
Anonymity](https://www.theguardian.com/world/interactive/2013/oct/04/tor-high-secure-internet-anonymity)."

- **Our downloads are verifiable**

Making sure that our users are really downloading an unmodified version of
our work is also critical to trust and security:

Our downloads are [[reproducible|contribute/build/reproducible]] to make sure that the process of building the downloads from our source code was not altered by our own infrastructure.

We provide [[strong and easy-to-use verification mechanisms|contribute/design/download_verification]] to make sure that our users are downloading a genuine copy of Tails.
