Your messages go to the network. Nowhere else.

Where your messages go On your computer, the tinyclient window talks to chatd over a local socket. chatd is always on, keeps messages and media on your disk and sessions in the system keychain, and connects directly, over encrypted connections, to Slack, Discord, Telegram, Microsoft Teams and Signal. mediad starts only during a call and connects to Discord's voice servers; tinyclient-login starts only to sign in and shows the network's own sign-in page.
