Is Lettres et CVs safe?

Low risk

Lettres et CVs sends Google search queries and extension identifiers to lettres-gratuites.azurewebsites.net after consent.

On Google search pages, the extension reads the search query and loads a lettres-content iframe with that query, a persistent user GUID, stored token values, install time, and a timestamp when consent is enabled. Its consent scripts accept page window messages without origin or source checks, so page scripts can set the consent state that enables later query collection or trigger the extension uninstall flow.
