Cookies are small text files that websites place on your device when you visit. They are widely used to make websites work, to remember your preferences, and to understand how visitors use a site.
Merveilleux uses cookies and similar technologies (such as local storage) to keep you signed in, remember your language and preferences, understand how the app is used, and — where advertising is shown — to support the delivery of relevant ads.
Essential cookies. These are required for the app to function. They keep your session secure, remember that you are signed in, and enable core features such as saving products to your favorites. Without them, parts of the app will not work.
Preference cookies. These remember the choices you make in the app — such as your language (English, French, or Spanish), your onboarding preferences, and items you have saved — so you do not have to set them again on every visit.
Analytics cookies. We collect anonymous, aggregate usage data (for example, which pages are visited and which buttons are clicked) to understand how the app is used and to improve it. This data does not identify you personally.
Advertising cookies. Where advertising is displayed on the site, third-party advertising partners may set cookies to deliver and measure ads. See the next section for details.
Merveilleux may display advertising served through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this or other websites.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google's Ads Settings at https://adssettings.google.com. You can also opt out of third-party vendor cookies for personalized advertising at https://optout.aboutads.info.
For more information about how Google uses data when you use our partners' sites or apps, see Google's Privacy & Terms at https://policies.google.com/technologies/partner-sites.
You can control and delete cookies through your browser settings. Every major browser (Chrome, Firefox, Safari, Edge) lets you view the cookies a site has stored, delete them, and block some or all cookies from being set in the future.
Please note: if you block or delete essential cookies, some parts of Merveilleux may not function correctly — for example, you may not be able to stay signed in, and your saved products or language preference may not be remembered.
To learn how to manage cookies in your browser, consult your browser's help documentation.
Where required by law (for example, in the European Union, the United Kingdom, and Canada), we present a consent notice before non-essential cookies are set. You can accept or reject non-essential cookies through that notice.
If you wish to change your choice later, you can clear cookies for this site in your browser settings, and the consent notice will be shown again on your next visit.
Some browsers offer a "Do Not Track" (DNT) signal. Because there is not yet a common understanding of how to interpret DNT signals, Merveilleux does not currently respond to them. You can still control tracking through your browser's cookie settings and the advertising opt-outs described above.
We may update this Cookie Policy from time to time to reflect changes in our practices or for legal reasons. When we make changes, we will update the "Last updated" date at the top of this page.
We encourage you to review this page periodically to stay informed about how we use cookies.
If you have any questions about this Cookie Policy or how cookies are used on Merveilleux, please reach out through our contact page.
