I. Personal data protection policy for SNCF entities

At SNCF, we’re committed to maintaining the highest ethical standards, in particular when it comes to protecting personal data.

In the course of our business, we collect and process personal data concerning our customers, our employees, and our partners (such as suppliers and service providers).

In an effort to promote innovation while at the same time building strong, lasting relationships based on mutual respect and shared, socially responsible values, we use technical and organizational measures to protect the personal data that we process.

This policy describes SNCF’s commitments concerning the protection of personal data.

We inform our customers, employees, and partners of the processing of their data.

SNCF’s aim in collecting personal data is optimizing management of our relationships with our customers, employees, and partners.

When SNCF processes data, we do so for specific purposes. Each time we process data, there is a legitimate, defined, and explicit purpose.

We ensure that the data is retained in a form that permits identification of the data subjects for no longer than is necessary to accomplish the purposes of this processing.

Each time SNCF processes data, we undertake to collect and use only such data as are adequate, relevant, and limited to what is necessary for the purposes for which the data is processed.

At SNCF, the security of personal data is a high priority.

We take technical and organizational measures to ensure that data is processed in a manner that ensures protection against accidental loss, destruction, or damage that could undermine its confidentiality or integrity.

When developing, designing, selecting, and using tools for the processing of personal data, we ensure (where applicable, working together with the tools’ publishers) that they provide an optimal level of protection for processed data.

SNCF takes measures that comply with the principles of data protection by design and data protection by default. To that end, when possible and/or necessary, we use the techniques of pseudonymizing and encrypting data.

When using a service provider, we communicate personal data only after obtaining the provider’s commitment to comply with SNCF security rules.

We conduct audits of our own departments and of our service providers to verify compliance with data security rules.

SNCF follows strict authorization policies to ensure that the data we process is transmitted only to persons that are authorized to have access to it.

When we need to transfer data to a location outside the European Union, we do so only in accordance with specific contractual provisions and in compliance with the requirements of the competent supervisory authorities.

At SNCF, we’re particularly careful to respect the rights of data subjects:

  • the right to be informed;
  • the right to access;
  • the right to rectification;
  • the right to erasure (the “right to be forgotten”);
  • the right to restrict processing;
  • the right to data portability;
  • the right to object; and
  • the right to issue directives regarding the retention, erasure, and communication of personal data after the data subject is deceased.


SNCF is able to respond to requests by data subjects to exercise their rights throughout processing, in compliance with the conditions and time limits imposed by applicable regulations.

Data subjects may make requests to exercise their rights by electronic means and/or by post, using the contact information provided in information notices, application and website terms of use, data collection forms, etc.

Data subjects must clearly state their first and last name, attach a copy of a form of identification, and indicate the address to which they would like the response to be sent.

We inform all data subjects wishing to exercise their rights if it is impossible to comply with their request.
