Tap the + button on the Connections tab. Enter host, port, username, and either a password or upload a private key (.pem). Free tier supports up to 2 servers; Pro is unlimited. Tap the row to connect.

Mosh requires UDP port 60000–61000 to be open on your server. Check your firewall (ufw allow 60000:61000/udp) and any cloud security group. The server must have mosh-server installed (`sudo apt install mosh` on Debian/Ubuntu). DuckTerm uses your existing SSH credentials to bootstrap the Mosh handshake.

On the Connections tab, swipe a server row left or tap into it; the snapshot view lists active tmux sessions. Tap a session row to attach (Pro only). DuckTerm uses native libghostty rendering for full color, mouse, and scrollback support.

Open Settings → Pro. Choose monthly ($0.99/mo), yearly ($9.99/yr — saves 17%), or lifetime ($14.99 one-time). Purchases unlock immediately and restore across devices via your Apple ID.

Settings → Pro → Restore Purchases. As long as you're signed in with the same Apple ID, your Pro entitlement comes back instantly. The lifetime purchase restores even after a fresh install.

Per-server Face ID gating is set independently. Tap the server row → Edit → Authentication → toggle "Require Face ID". If you accidentally enrolled with the wrong server, just toggle off and re-enable on the right one.

Both devices must be signed into the same Apple ID with iCloud Drive enabled. Open Settings → iCloud Sync and ensure it's on for both. First sync can take a minute. Secrets (passwords, keys) never sync — those stay in the Keychain.

Subscriptions are managed by Apple. Settings (iOS) → your Apple ID → Subscriptions → DuckTerm → Cancel. You retain Pro access until the end of your billing period. The lifetime purchase isn't a subscription — there's nothing to cancel.

Settings → About & Legal → Delete All Data. This wipes the local Keychain entries, server list, snippets, snapshots, and inbox events. iCloud-synced metadata is also marked for deletion. The action is irreversible.
