1. What is a cookie or tracker?
A cookie is a small file placed on your device when you visit a site. Trackers also include similar technologies: browser local storage, invisible pixels in pages and in emails, and server-side measurement. They allow the site to function, let us measure its audience, or personalize content, communications and advertising.
2. Who sets trackers on this site?
Nouvel Heritage (data controller), and partners acting with your consent: Shopify (our e-commerce platform, including Shopify Analytics, Shop Pay, platform monitoring and Shopify Network Intelligence — see Shopify's privacy policy), Klaviyo (email), Meta (Facebook & Instagram), Google (Google Analytics, Google & YouTube, Google Ads, Google Merchant Center), Pinterest, Snapchat, TikTok, Front (customer service messaging) and Bugsnag (error monitoring). Advertising and analytics trackers are loaded through Shopify's consent framework and are only activated after you accept the corresponding category.

4. Legal basis
Trackers strictly necessary for the operation and security of the site are exempt from consent. All others (audience measurement, personalization, marketing) are only set or read with your consent, which you may withdraw at any time.
5. How long your choice is kept
Your choice (accept or refuse) is stored for a maximum of 13 months, after which you will be asked again. Proof of your choice is kept by our platform (consent ID).
6. Changing your choices
Use the “Cookie settings” button available at the bottom of every page.
7. If you refuse
The site remains fully usable (browsing, cart, checkout). Visit statistics that help us improve the site, personalized content, and advertising measurement will be unavailable.
8. Tracking pixels in our emails
We do not record email opens for recipients in the European Union, the European Economic Area or the United Kingdom. No open-tracking pixel is used there, and no open statistics are collected. Outside those territories, our commercial emails may contain a pixel indicating whether an email was opened, so we can measure the effectiveness of our communications and keep our mailing list healthy. You may object at any time by writing to concierge@nouvelheritage.com. This changes nothing about the emails you receive.
