End-to-End Encryption
Video, audio, and images are encrypted end-to-end using WebRTC standards, and are delivered using a peer-to-peer delivery model.
Session summaries shown at the end of a Chalk session are captured on each user’s local device (not stored on a server). If a user does not choose to export the images, they are deleted and cannot be retrieved at a later time. For more information about session summaries, see Session Summaries.
