Calls and group calls

Voice and video calls are end-to-end encrypted, one to one or in a group, with up to 8 people on video and 32 on voice.

• Calls go directly between devices where they can. When they can't, our relay or media server passes on encrypted audio and video it can't decode, and group calls on the media server get a second layer of encryption with a key only the people on the call have.
• We never record calls or keep what's said. Someone in a call can record it on their own device: everyone in the call sees Recording and hears a tone, and the recording stays on that person's device, never on our server.
• Share your screen in any video call, one to one or in a group (one person at a time), in the Android and Windows apps and the web app on a computer.
• On Android, a video call keeps going in a small window when you leave the app.

In a one-to-one call either of you can record. In a group, its admins decide whether calls can be recorded.
