Is ToDiagram safe?

Low risk

ToDiagram lets its editor pages retrieve selected text and page titles saved for diagram editing.

When you send content to ToDiagram, the extension stores the selected text and current page title in browser session storage and opens the ToDiagram editor. Pages allowed by the extension's external messaging rules, including todiagram.com and localhost editor URLs, can request that stored text and title with the expected message.
