Is Screen Canvas - Draw on any Web page safe?

Clean risk

Screen Canvas sends annotation-sharing requests to services.lisenser.com with a bundled API key.

When a user shares an annotation, the extension posts the annotation-sharing request to services.lisenser.com and includes a hardcoded X-Api-Key header. It also sends a follow-up completion request with the shared annotation UID to the same service.
