Frequently Asked Questions
How does the connection work?
It uses WebRTC with a manual signalling handshake — you paste an offer code to your peer, they paste an answer back. Once connected, drawing data flows peer-to-peer with no server in the middle.
Is any data uploaded anywhere?
No. Strokes, chat and cursors stay strictly between the connected browsers.
Can more than two people join?
The host can create additional invite codes for each extra peer — the mesh is built one handshake at a time.
What happens if I refresh?
The board is not persisted. Export a PNG snapshot before you close the tab if you want to keep it.
