Keep It Private

Big Brother is watching Slack. Clamshell is end-to-end encrypted and everyone at work is already on it.
Two devices and a secure message with end-to-end encryption in action.

Connect with coworkers, off-the-record

State-of-the-art end-to-end encryption (powered by the open source Matrix Protocol) keeps your conversations secure. We can't read your messages, and no one else can either. Privacy isn’t optional — it’s just the way that Clamshell works.
Every message, every file, every time.
