  2. What is the Tor Project and what does it do?

    The Tor Project's mission is to advance human rights and freedoms by creating and deploying free and open anonymity and privacy technologies, supporting their unrestricted availability and use, and furthering their scientific and popular understanding. The main product of the Tor Project is Tor Browser, which enables people to browse the internet anonymously. The Tor Project is a 501(c)3 tax-exempt non-profit organization. It was founded in 2006.

  3. Who works for the Tor Project, and what do they do?

    Thousands of people around the world actively support the work of the Tor Project, including developers, designers, relay operators, researchers, cryptographers, computer scientists, and privacy advocates, and most are not paid by the Tor Project. The paid staff of the Tor Project is very small: about 47 people in total. You can read about the core contributors to the Tor Project on our Core People page.

  4. Who uses Tor?

    The vast majority of Tor users are ordinary people who want control of their privacy online or people whose internet use is censored. Other Tor users are journalists, human rights defenders, domestic violence survivors, policymakers, diplomats, and academic and research institutions.

  5. Can anyone use Tor?

    Yes! Tor is free, and anyone can use it. To get started, you will need to download Tor Browser. We offer instructions on how to download for Windows, Mac OS X, Linux, and Android.

  6. What kinds of people support Tor?

    All kinds of people. Thousands of individuals have donated to support the Tor Project, and we have also received funding from a wide range of organizations including Google, the Ford Foundation, the Knight Foundation, Reddit, the U.S. National Science Foundation, the Electronic Frontier Foundation, Human Rights Watch, the Swedish International Development Cooperation Agency, the Federal Foreign Office of Germany, the U.S. Naval Research Laboratory, Omidyar Network, SRI International, and Open Technology Fund. People also support Tor in non-financial ways, for example by running Tor relays to help carry traffic for other users. In addition, everybody who uses Tor is helping to keep other users safe and anonymous, because the more people using Tor, the harder it is to identify any single individual.

  7. How does the Tor software work to protect people's anonymity?

    Tor protects you by bouncing your communications around the Tor network, which is a distributed network of relays run by volunteers all around the world. If someone is watching your internet connection, Tor prevents them from finding out what sites you are visiting. It also prevents sites you visit from finding out where you're located. Watch this video to learn more about how Tor works.

  8. I would like to know more about how Tor works, what onion services are, or how to run a relay.

    This Tor Project FAQ has answers to all those questions, and more.

  9. Does the Tor software work?

    We believe Tor is the best solution available today, and we know that it does a better job of keeping you safely anonymous than other options such as VPNs, proxychains, or browser "private browsing" modes. We know that both the Russian government and the NSA have tried in the past to crack Tor, and failed. The Electronic Frontier Foundation says that Tor offers some of the strongest anonymity software that exists, and in his book Data and Goliath, security expert Bruce Schneier wrote, "the current best tool to protect your anonymity when browsing the web is Tor."

  10. Is what Tor does legal? Can I get in trouble for using it?

    Downloading Tor Browser or using the Tor network is legal in nearly every country. A few web sites occasionally block Tor, but that doesn't mean you're doing anything wrong. Usually it means that site has had difficulties with visitors who've been using Tor in the past, or that they misunderstand what Tor is and how it works (we’re working to change this). But it is not illegal to use Tor, and you shouldn't get in trouble for doing it. You can find more information about Tor's legal status on the EFF site.

  11. Where can I find out more about the Tor Project, especially financial information?

    Here are the Tor Project's financial statements and its Form 990.

  12. Where does the Tor Project's money come from?

    Tor is supported by United States government funding agencies, NGOs, private foundations, research institutions, private companies, and over 20,000 personal donations from people like you. (See our Sponsors Page for more.) While we are grateful for this funding, we don't want the Tor Project to become too dependent on any single source. Crowdfunding allows us to diversify our donor base and is unrestricted -- it allows us to spend the money on the projects we think are most important and respond quickly to changing events. And so, we are asking you to help financially support us, to increase the Tor Project's independence and ensure the sustainability of the products and services we provide.

  13. How much money does the Tor Project spend annually, and what is it used for?

    The Tor Project spends about $5 million annually. About 80% of the Tor Project's spending goes to staffing, mostly software engineers. About 10% goes towards administrative costs such as accounting and legal costs and bank fees. The remaining 10% is spent on travel, meetings and conferences, which are important for Tor because the Tor community is global.

  14. Is my donation tax-deductible?

    If you pay taxes in the United States, your donation to Tor is tax deductible to the full extent required by law. Following is information you may need for reporting purposes:

    Tor Project Tax ID Number (EIN #): 20-8096820
    The Tor Project, Inc.
    217 First Avenue South #4903
    Seattle, WA 98194
    Phone number: 206-420-3136
    Contact person: Isabela Bagueros, Executive Director

    For European bank transfers, we have an arrangement with the Renewable Freedom Foundation to provide tax-deductible donations for Europeans. They will issue a donation receipt upon request. The account information is as follows:

    Renewable Freedom Foundation
    IBAN: DE17721500000053693701
    Sparkasse Ingolstadt
    Rathausplatz 6
    85049 Ingolstadt

  15. If I am not in the United States, can I still donate?

    Yes, definitely. Your donation probably isn't tax-deductible (unless you pay taxes on U.S. income) but we would very much appreciate your support.

  16. It's important to me that my donation be tax-deductible, but I don't pay taxes in the United States.

    Right now, we can only offer tax-deductibility to donors who pay taxes in the United States. If it's important to you that your donations be tax-deductible in a different country, let us know and we will try to offer tax-deductibility in your country in the future. Or, if you are in Germany, France, or Sweden, these organizations support the Tor network and may be able to offer you tax-deductibility for your donation. is a German charitable non-profit that runs a wide variety of exit relays worldwide. They also like donations of bandwidth from ISPs.

    Noisebridge is a US-based 501(c)(3) non-profit that collects donations and turns them into more US-based exit relay capacity.

    Nos Oignons is a French charitable non-profit that runs fast exit relays in France.

    DFRI is a Swedish non-profit running exit relays.

    These organizations are not the same as The Tor Project, Inc, but we consider that a good thing. They're run by nice people who are part of the Tor community.

  17. Can I donate to a specific project, or restrict my donation to a particular purpose?

    No, sorry. If we accept a donation from someone who has specified how they want it used, we're required by the IRS to track and report separately on that money. That would be a big administrative burden for a small organization, and we don't think it's a good idea for us. However, we would be very happy to hear your ideas and feedback about our work. If you're donating using a mechanism that allows for comments, feel free to send your thoughts that way.

  18. Can I donate while using Tor Browser?

    Yes! In our testing, donation works via Tor Browser. If you run into problems, please contact .

    For users logging in to Paypal: some people had no problem donating via PayPal while using Tor Browser. Some users experience issues because PayPal limits the number of times an IP address can be used in a certain period of time. This is to prevent fraud from card testers. If you run into an issue, please try again. Unfortunately, when we are receiving a high volume of donations, you might need to use a different browser.

  19. How can I donate via debit or credit card?

    To donate using a major credit card or debit card (VISA, MasterCard, Discover or American Express) or via PayPal, please visit our donate page.

  20. Why do you ask for my address and similar information?

    If you donate by credit card, you will be asked for some information that's required to process your credit card payment, including your billing address. This allows our payment processor to verify your identity, process your payment, and prevent fraudulent charges to your credit card. We don't ask for information beyond what's required by the payment processor.

  21. Why is there a minimum donation?

    People who have stolen credit card information often donate to nonprofits as a way of testing whether the card works. These people typically use a very small amount for their testing, and we've found that setting a $2 minimum donation seems to deter them.

  22. Is there a maximum donation?

    Nope. More funding from you means we can do more things we are excited to do, like hire a person to monitor the Tor network full time, or research, test, and implement ideas we have for making the Tor network even stronger.

  23. Do you accept cash donations?


  24. Can I donate via AmazonSmile?

    Amazon Smile is a website operated by Amazon with the same products, prices, and shopping features as The difference is that when you shop on Amazon Smile, the Amazon Smile Foundation will donate 0.5% of the purchase price of eligible products to the charitable organization of your choice.

    Set up the Tor Project on Amazon Smile

  25. Can I donate via Giving Assistant?

    Giving Assistant helps you donate a percentage of your cash back earnings to us with every purchase you make at 3,000+ popular online retailers.

    Use Giving Assistant to save money and support the Tor Project

  26. Is the Tor Project required to identify me as a donor to the United States government, or to any other authority?

    If you donate $20,000 or more to the Tor Project in a single year, we are required to report the donation amount and your name and address (if we have it) to the IRS, on Schedule B of the Form 990, which is filed annually. However, it's normal for nonprofits to redact individual donor information from the copy of the 990 that's made publicly-available, and that's what we do. We are not required to identify donors to any other organization or authority, and we do not.

  27. In your privacy policy, you say you will never publicly identify me as a donor without my permission. What does that mean?

    Yes, that's right. If you donate to the Tor Project, there will be some people at the Tor Project who know about your donation. However, we will never publicly identify you as a donor, unless you have given us permission to do so. That means we won't post your name on our website, thank you on Twitter, or do anything else that would publicly identify you as someone who has donated. If we decide we would like to publicly name you as a donor, we will ask you first, and will not do it until and unless you say it's okay. If you talk about your donation on social media (and we appreciate you doing so!), we will take that to mean it's okay for us to engage with or amplify your post.

  28. What is your donor privacy policy?

    Here is the Tor Project donor privacy policy.

  29. What is your refund policy?

    If you want your donation refunded, please tell us by emailing . To process your refund we'll need to know the date of your donation, the amount you donated, your full name, the payment method you used and your country of origin. Please also tell us why you're asking for a refund. Please note that some payment methods won't support refunds, or require them to be made in a specific way, so we may need additional information from you in order to process yours.

  30. Does Tor Project accept matching donations?

    Yes! Many companies --such as Google, Microsoft, eBay, PayPal, Apple, Verizon, Red Hat, many universities, and others-- will match donations made by their employees. The fastest way to find out if your company matches donations is usually by checking with your HR department. If you want help figuring out the process, write us at

  31. Can I become a Tor Project member?

    Right now, we don't have a membership program, but we may set one up in the future. If you want to get involved with the Tor Project, this is a good place to start. We do have two giving programs - Champions of Privacy and Defenders of Privacy. Champions of Privacy donate $1,000 or more per year and enjoy special perks and access. Defenders of Privacy sign up to donate monthly and receive an exclusive patch.

  32. How can I get a Tor t-shirt or stickers?

    A variety of thank-you gifts for donors, including t-shirts, hoodies and stickers, are presented on our main donation page.

  33. If I want to stay in touch with the Tor Project, what's the best way for me to do that?

    You can sign up to receive Tor News, read the Tor Blog, or follow us on Twitter.

  34. Does the Tor Project participate in the Combined Federal Campaign program?

    Tor is set up to participate in the King County Employee Giving Program. Tor doesn't currently participate in the Federal CFC program. If you'd like to get Tor added to the CFC program in your location, that would be great: please let us know if you need any help.

  35. Can I donate my airline miles, flight vouchers, or hotel points?

    No, sorry. We would like to accept your miles, vouchers and hotel points, and in the future we may be able to.

  36. Can I donate hardware?

    Typically no, we don't encourage people to donate hardware. But if you want to make a hardware donation that you think might be especially useful for us, please mail .

  37. Can I donate my time?

    Yes. Here's a list of areas where we would love your help.

  38. I would like my company to support Tor. What can we do to help?

    Your company could match donations made by its employees to the Tor Project--that would be wonderful. Your company may operate a corporate foundation that gives out grants, and if so, you should encourage it to fund us. Maybe your company would be willing to operate a Tor relay. If your company sells cloud services, perhaps it could donate these to Tor: We use them in some anti-censorship projects.

  39. You don't support my preferred way to donate. Can I recommend a new donation method to you?

    Sure. Just mail us at .

  40. Will the Tor Project accept donations from anybody, or do you reserve the right to reject support from specific organizations or individuals?

    We do reserve the right to reject a donation. To date though, we haven't exercised that right. We are happy that a broad range of people use and support Tor.

  41. I have more questions. How can I get answers?

    Feel free to send questions to . We will try to answer you, and we'll also post your question (and the answer) here.
