Is LEOs Dictionaries safe?

Clean risk

LEOs Dictionaries sends user-selected text to dict.leo.org when the user starts a dictionary lookup.

When you use the extension's context menu or keyboard shortcut, it reads the selected text from the active page and opens a LEO dictionary URL containing that text. The lookup is user-initiated and sends the selected word or phrase to dict.leo.org as part of the search path.
