These store your language and currency choice, your consent, your cart and what the portal needs to work.
We count visits to improve the site: the page viewed, the site you came from, the campaign, approximate country and city, device and browser type, time spent, scrolling, buttons clicked and checkout steps. Nothing is stored on your device and your IP address is never kept: it is only used, mixed with a key that changes every day, so the same visit isn't counted twice in one day. What you type into forms is never measured.
A random ID is kept on your device (local storage “yya-vid”, thirteen months at most) to recognize a return visit. If you decline, nothing is kept on your device: the pages of a single visit are only linked together by the daily fingerprint described above, which is never stored in readable form.
This audience data stays with us: a database hosted by Supabase in Paris, accessed by our team, never sold. It is deleted automatically after thirteen months. Advertising, described below, is the only case where data goes to a third party.
On the public pages of our website, we load the Meta Pixel and the Conversions API to measure and optimize our ads. Meta sets the _fbp and _fbc cookies and receives your IP address, your browser and device, the pages you view and any ad click ID; this information is processed by Meta Platforms, including in the United States, under its own policy. The pixel is never on our clients' invitations or in the client portal. To opt out, use the ad settings of your Meta account or block third-party cookies in your browser.
So our ads reach the right people, we also share with Meta, as an irreversible hash (SHA-256), the email, first name, last name and phone number you enter in a form or at checkout, along with your city, state or region, ZIP or postal code and country, taken from your billing address or your connection. Order details come with them: design, plan, amount and order number. Meta uses them to match an existing account, never to contact you.
The choice banner is shown to visitors located in Europe and the United Kingdom, based on their device’s time zone; elsewhere, audience measurement works as described above, with no ID kept on the device. You can change your mind at any time by clearing the site’s data in your browser: the banner will appear again.
