## What it is
|
||
|
||
Signal is a messaging app run by the nonprofit Signal Foundation. Every message, call and attachment is end-to-end encrypted with the Signal Protocol, and the service keeps as little data about you as it can. Signal Desktop is the computer version: it links to the Signal app on your phone and shows the same chats.
|
||
|
||
## Why it's here
|
||
|
||
- **Private by design.** Encryption is always on, for everyone, with nothing to configure.
|
||
- **Type on a real keyboard.** Chats, group calls and file sharing from your phone work on the desktop too.
|
||
|
||
## On CoreDesktop
|
||
|
||
CoreDesktop installs Signal as a Flatpak from Flathub. Open it from the app grid and scan the QR code it shows with Signal on your phone (**Settings › Linked devices**). The sandboxed AI agents can't read Signal's data. `update` keeps it current along with your other Flatpaks.
