After completing the standard audit, our 2014 state and federal tax filings are available. We publish all of our related tax documents because we believe in transparency.

Tor's annual revenue in 2014 held steady at about $2.5 million. Tor's budget is modest considering the number of people involved and the impact we have. And it is dwarfed by the budgets that our adversaries are spending to make the world a more dangerous and less free place.

To achieve our goals, which include scaling our user base, we fund about 20 contractors and staff members (some part time, some full time) and rely on thousands of volunteers to do everything from systems administration to outreach. Our relay operators are also volunteers, and in 2014 we grew their number to almost 7,000 — helped along by the Electronic Frontier Foundation's wonderful Tor Challenge, which netted 1,635 relays. Our user base is up to several million people each day.

Transparency doesn't just mean that we show you our source code (though of course we do). The second layer to transparency is publishing specifications to explain what we thought we implemented in the source code. And the layer above that is publishing design documents and research papers to explain why we chose to build it that way, including analyzing the security implications and the tradeoffs of alternate designs. The reason for all these layers is to help people evaluate every level of our system: whether we chose the right design, whether we turned that design into a concrete plan that will keep people safe, and whether we correctly implemented this plan. Tor gets a huge amount of analysis and attention from professors and university research groups down to individual programmers around the world, and this consistent peer review is one of our core strengths over the past decade.

As we look toward the future, we are grateful for our institutional funding, but we want to expand and diversify our funding too. The recent donations campaign is a great example of our vision for future fundraising. We are excited about the future, and we invite you to join us: donate, volunteer, and run a Tor relay.

2013 was a great year for Tor. The increasing awareness of the lack of privacy online, increasing Internet censorship around the world, and general interest in encryption has helped continue to keep us in the public mind. As a result, our supporters have increased our funding to keep us on the leading edge of our field, this of course, means you. We're happy to have more developers, advocates, and support volunteers. We're encouraged as the general public talks about Tor to their friends and neighbors. Join us as we continue to fight for your privacy and freedom on the Internet!

Part of our transparency is simply publishing the tax documents for your review. The other part is publishing what we're working on in detail. We hope you'll join us in furthering our mission (a) to develop, improve and distribute free, publicly available tools and programs that promote free speech, free expression, civic engagement and privacy rights online; (b) to conduct scientific research regarding, and to promote the use of and knowledge about, such tools, programs and related issues around the world; (c) to educate the general public around the world about privacy rights and anonymity issues connected to Internet use.

All of this means you can look through our source code, including our design documents, and all open tasks, enhancements, and bugs available on our tracking system. Our research reports are available as well. From a technical perspective, all of this free software, documentation, and code allows you and others to assess the safety and trustworthiness of our research and development. On another level, we have a 10 year track record of doing high quality work, saying what we're going to do, and doing what we said.
