How does P2P sync work?

PeerJS WebRTC DataChannel creates a direct connection. All text is synced P2P without going through a server.

What is LWW conflict resolution?

Last-Write-Wins: when conflicts occur, the most recent edit (by timestamp) is kept. Edits are based on content, not user.

Can I use Markdown preview?

Yes. Toggle between edit mode and preview mode which renders Markdown using marked.js.

Is my data sent to a server?

Only signaling (room codes/peer IDs) goes through PeerJS servers. The actual text content is transferred directly P2P.
