Is Annotate Web safe?

Medium risk

Annotate Web stores page-specific drawing and text annotation history in each visited site's localStorage.

When you use the toolbar button, Annotate Web injects its drawing tool into the active page and saves annotation history keyed to that page URL. The saved data can include text, colors, coordinates, element references, and bounds, and it is written into the visited site's own localStorage where scripts from that site can read it.
