Signal is a cross-platform messaging app. Privacy isn’t an optional mode – it’s just the way that Signal works. Every message, every call, every time.

We are sponsoring this year’s Grace Hopper Celebration (@ghc), and have one extra ticket for free registration. 👩‍💻 If you’re a woman in tech interested in (virtually) attending, write us at ghc2021@signal.org, and we’ll find a good home for our extra seat 🙂

Set it and forget it, literally. The new default disappearing message feature lets you choose just how long you’d like new conversations to hang around. Learn more about it here: signal.org/blog/disappearing…

Looks like the Indian government has been secretly attempting to surveil political opposition parties, journalists, activists, clerics, and labor unions. Interesting coincidence that they've also been advocating legislation to weaken encryption lately! theguardian.com/news/2021/ju…

The UK is still trying to figure out Brexit, another Justin Bieber song hit #1 on the charts, and Signal still doesn't really know anything about you. In many ways, not much has changed between 2016 and 2021 — including the way we respond to subpoenas: signal.org/bigbrother/centra…

Nobody ever invited Big Tech to join a group chat, but they still hang around and know what's going on. Signal knows nothing. Private groups protect your group names, group membership, group messages, and even the group avatar with end-to-end encryption. signal.org/blog/signal-priva…

Big Tech knows who your contacts are. Here at Signal, we know nothing. Signal technology like Private Contact Discovery keeps your address book far away from our address. signal.org/blog/private-cont…

About an hour ago, some Signal users experienced delays sending and receiving messages. One small cluster of servers got confused and thought that Sunday was a day of rest for them too. We apologize for the brief inconvenience while everything automatically recovered.

When everything is end-to-end encrypted, it's OK to use colourful language. Happy Holi from all of us at Signal.

Signal registrations are through the roof; welcome everyone! Solidarity to the folks working on the WhatsApp outage. People outside of the tech industry will never understand how weird it sounds when someone says that they are "looking forward to some weekend downtime.
