Is Lettres Gratuites safe?

Low risk

Lettres Gratuites sends a letter-template search match flag from Google searches to lettres-gratuites.azurewebsites.net.

On Google search result pages, the extension reads the search query and checks whether it matches phrases such as letter templates, resignation letters, or complaint letters. It then loads an iframe from lettres-gratuites.azurewebsites.net with a derived 0-or-1 match flag, a stored family identifier, and a timestamp rather than the full query text.
