What is processed
| Purpose | Data | Legal basis | Retention |

To book a call, you go through Cal.com, which receives your name, your e-mail, your company name and what you type about your need. This data is used to organise and prepare the call.
The task measurement and the preparation questionnaire run in your browser: nothing is sent until you click “Send by e-mail”.
Audience measurement: Umami, installed on the site's server at OVH, in France, with no cookies. It counts page views, the page you came from (for example a search engine or an AI assistant), the country, the device type and the browser. Your IP address is not stored and nothing is used to follow you from one site to another. Legal basis: legitimate interest in measuring the site's traffic. Retention: 25 months at most. If your browser sends the “Do Not Track” signal, nothing is measured.
Server logs: IP address, page requested, date and browser, kept 14 days for the site's security (legitimate interest).
Recipients and processors
- Site and form hosting: OVH SAS (France).
- Business e-mail, calendar and delivery of the quote form: Google Workspace, resold by Squarespace.
- Booking: Cal.com.
- WhatsApp: Meta, only if you choose that channel.
