Signal Private Messenger

Privacy is possible, Signal makes it easy.

Using Signal, you can communicate instantly while avoiding SMS fees, create groups so that you can chat in real time with all your friends at once, and share media or attachments all with complete privacy. The server never has access to any of your communication and never stores any of your data.

★ Say Anything. Signal uses an advanced end to end encryption protocol that provides privacy for every message every time.

★ Open Source. Signal is Free and Open Source, enabling anyone to verify its security by auditing the code. TextSecure is the only private messenger that uses open source peer-reviewed cryptographic protocols to keep your messages safe.

★ Be Yourself - Signal uses your existing phone number and address book. There are no separate logins, usernames, passwords, or PINs to manage or lose.

★ Group Chat. Signal allows you to create encrypted groups so you can have private conversations with all your friends at once. Not only are the messages encrypted, but the Signal server never has access to any group metadata such as the membership list, group title, or group icon.

★ Fast. The Signal protocol is designed to operate in the most constrained environment possible. Using Signal, messages are instantly delivered to friends.

★ Speak Freely - Make crystal-clear phone calls to people who live across town, or across the ocean, with no long-distance charges.

Signal is not currently compatible with tablets, but support for larger screens is on our roadmap and will be included in a future release!

We’re glad those are the choices we’ve made. Today, we are launching the Signal Foundation, an emerging 501(c)(3) nonprofit created and made possible by Brian Acton, the co-founder of WhatsApp, to support, accelerate, and broaden Signal’s mission of making private communication accessible and ubiquitous. In case you missed it, Brian left WhatsApp and Facebook last year, and has been thinking about how to best focus his future time and energy on building nonprofit technology for public good.

Starting with an initial $50,000,000 in funding, we can now increase the size of our team, our capacity, and our ambitions. This means reduced uncertainty on the path to sustainability, and the strengthening of our long-term goals and values. Perhaps most significantly, the addition of Brian brings an incredibly talented engineer and visionary with decades of experience building successful products to our team.

The Signal Foundation completes our vision of Signal operating as part of a full 501(c)(3). Up until now, we’ve never been able to take on the 501(c)(3) management overhead ourselves, and we’ve relied on the generosity of the Freedom Of The Press Foundation as our fiscal sponsor. Without their support, Signal would not be where it is today, and they have graciously agreed to continue accepting donations on our behalf while our status is pending.
