What data do we collect ?

At Oui.sncf, we scrupulously follow the principle of "minimisation", meaning that we collect only the data that is strictly necessary to the purposes defined above, namely:

  • identification data (name, email address, IP address) : This data is essential for any orders, registration for a customer account or for the security of the sites and transactions of Oui.sncf;
  • banking data : This data is essential for any orders or reimbursements. Also, you can register your banking details (except the card security code) in your customer account to facilitate your future purchases;
  • data related to your searches and your order (product purchased (destination, date, price,…)) : This data is essential to provide the ordered service and after-sales service;
  • data related to your habits and centres of interest (favourite destinations, choice of additional services,…) : This data is useful for making personalised offers;
  • contact data (telephone no, email address, postal address) : This data is useful to contact you if required (problem related to your order or a purchased product, travel information) or to send you your train tickets, either to your home or electronically;
  • technical data: during browsing, Oui.sncf collects information such as the version of your browser, operating system used or the model of terminal used. This data is necessary for optimal display and functioning of Oui.sncf sites and applications;
  • geolocation: the Oui.sncf mobile application includes a geolocation function that can be activated exclusively through consent from you. This data lets us offer you personalised services (closest station/next departure from the nearby station);
  • browsing data (searches, number of visits, date of last visit,…) : This data is useful for making commercial offers.
