Is Connecteur Antidote safe?

This extension connects browser writing to Antidote for corrections, dictionaries, and language guides.

It adds an Antidote toolbar connector for checking editable browser text with Correction Express, submitting selected text to Antidote, and applying edits back to the original text. You can also select words to open Antidote dictionaries or language guides at the relevant entry. An existing Antidote access is required, and some features transmit text to Druide servers.
