🔐 Privacy & End-to-End Encryption (E2EE) in CollabyDraw

CollabyDraw is built with privacy by design to ensure that no sensitive drawing data can be accessed by anyone other than the intended participants.

🔑 How It Works

• When a user creates or joins a room, the app generates a link like:

  <https://collabydraw.app/#room=abc123,xyz456>
  

  • abc123: Unique room ID (used by the server)
  • xyz456: Encryption key (used only on the client)

🧠 Key Never Touches the Server
