Is Train Complet safe?

Train Complet sends your SNCF booking details, name, email, phone, and card numbers, to traincomplet.fr as unencrypted URL parameters.

When you use SNCF Connect, the extension intercepts the site's own account and authentication API responses to collect your name, email, phone number, birth date, and discount/loyalty card numbers, along with your selected trains and travel date. It then opens a confirmation page on traincomplet.fr, passing all of this personal data unencrypted in the page URL rather than in a request body. Because it travels as URL query parameters, this data can end up in browser history and in server or proxy logs along the way.
