A cookie is a small file that a website stores in your browser to recognize it from one page to the next. We use very few. Here are the ones we use, why, and how to stay in control.
On our site
With your consent, and only with it, we measure site traffic with Google Analytics: how many visits, which pages are read, on what type of device. This tells us what is useful to you, and what is not. Until you respond, and if you decline, no measurement cookie is stored and Google is not even contacted.
We have set up Google Analytics to collect as little as possible. Its cookies expire no later than 13 months after they are set, with no extension on each visit, the data is not combined with any Google account you may have, and it is never used for advertising.
If you switch the site's language with the “English” or “Français” link, a cookie remembers your choice. The site then stays in that language from page to page and on your next visits, instead of following your browser's language. It is used for nothing else, and the law exempts it from your consent.
On the booking page
The calendar on the booking page is provided by Cal.com and is displayed within our page. To work and to protect itself from bots, it sets a few technical cookies, on that page only, since it is loaded nowhere else. They are not used to track you or for advertising, and the law exempts them from your consent, because the calendar could not work without them.
Cal.com also sends technical error reports to its provider Sentry, to fix its service. What Cal.com does with this information is detailed in the Cal.com privacy policy (opens in a new tab).

Recorded in a fresh browser, on October 20, 2026 up to choosing a day, and on September 25, 2026 for the form step.
| Name | Set by | What it's for | Duration | Your consent |
|---|---|---|---|---|
| nuera_lang | Nuera Studio | Remember the language you chose, French or English, so the site keeps it from page to page and from one visit to the next | 12 months | No, it remembers your language choice |
| nuera_consent | Nuera Studio | Remember your cookie choice, accepted or declined, so we don't ask you again on every page | 6 months | No, it ensures your choice is respected |

Change your mind
Your choice is kept for 6 months, after which we ask you again. You can change it at any time, in one click, with the “Manage cookies” link at the bottom of every page and below the calendar on the booking page, or with the button below. Declining changes nothing about your visit.
