Invite participants
- Open collaboration in Web Canvas and create a room.
- Send the complete editing link to participants.
- Wait for the canvas to sync after they open the link, then start editing.
When a new device joins, at least one participant holding a local copy of the content must be online. Sharing a normal canvas page URL does not create a collaboration room.
Protect the editing link
Anyone with the complete editing link can read and edit the room's content. Share it only with people who should have that access.
Canvas content and presence data are encrypted in the browser before transmission. The service still sees connection information such as connection times and IP addresses; encryption does not hide all metadata.
Leave and keep a copy
The relay deletes the room when the last participant leaves. Participants keep local copies in their own browsers. A collaboration room is not a long-term backup.
Before ending a session, export a native file to keep or edit independently.
