- Replying to your request and, where relevant, preparing a proposal: steps taken at your request prior to a contract.
- Protecting the website and the form against abuse: the publisher's legitimate interest.
Your data is never sold or transferred, and is not used for any automated prospecting.

| Messages received and the exchanges that follow | 3 years after the last contact |
| Client data | For the duration of the relationship, then archived for the legal periods |
