Policy Cookies

A cookie is a small text file placed on your device (computer, smartphone, tablet) by the server of the website you are visiting. It is stored by your browser and allows the website to recognize your device during your subsequent visits, to remember certain information about you, and to personalize your experience.

Cookies do not contain viruses and cannot damage your device. They do not allow direct access to personally identifiable information such as your name or email address, unless you have previously provided this information to the website.

In addition to cookies in the strict sense, the MACENTRALE website may also use similar technologies such as:

• Tracking pixels: small transparent images embedded in pages or emails to measure opens and clicks
• Local storage (localStorage / sessionStorage): A browser mechanism that allows data to be stored client-side, similar to cookies but without an automatic expiration date.
• Web beacons: scripts that collect information about user interactions with a web page

This policy applies to all of these tracking technologies, hereinafter collectively referred to as "cookies".

MACENTRALE uses cookies for several reasons essential to the proper functioning of its e-commerce activity and the quality of your browsing experience:

• Technical operation of the site: Some cookies are essential for the site to function correctly. Without them, you would not be able to browse the site or place an order.
• Your session saved: to keep your connection active and remember the contents of your shopping cart between visits
• Securing exchanges: to protect your data and prevent fraud attempts or unauthorized access to your account
• Continuous improvement of the site: to analyze how you use the site and identify areas for improvement in terms of usability and content
• Personalize your experience: to remember your preferences and offer you content tailored to your interests
• Measuring the effectiveness of our campaigns: to evaluate the performance of our marketing and advertising campaigns

These cookies are essential for the website to function and cannot be disabled in our systems. They are generally set in response to actions you take on the site (login, form submission, adding to cart). You can configure your browser to block them, but some parts of the site will then no longer function correctly.

• Session cookie: keeps your connection active while you browse and avoids asking you for your login details on each page
• Shopping cart cookie: remembers the products you have added to your shopping cart, including between sessions
• Cookie CSRF (Cross-Site Request Forgery) : A security token that protects your forms against cyberattacks involving query forgery.
• Cookie consent preferences: Remembers your cookie preferences to avoid asking you the same question on each visit (validity period: 13 months)
• Load balancing cookie: allows traffic to be distributed between servers to ensure site availability

These cookies help improve the functionality and personalization of the site. Without them, some services may not function optimally.

• Language cookie: Remembers the selected language to display the site in your preferred language.
• Currency cookie: remembers your preferred currency for price display
• Wishlist cookie: remembers the products you have added to your favorites list
• Product comparison cookie: memorizes the selected products for comparison

These cookies allow us to collect aggregated and anonymized information about how visitors use the site (pages visited, visit duration, bounce rate, etc.). This data helps us to continuously improve our site.

• Google Analytics (_ga, _gid, _gat) : audience measurement, analysis of browsing behavior and conversion funnels
• A/B test cookie: allows you to test different versions of a page to identify the best performing one
• Performance cookie: measures page load times and identifies technical friction points
• Acquisition source cookie: identifies the source that led the visitor to the site (search engine, campaign, direct link)

These cookies are used to present you with relevant advertisements on other websites after your visit to MACENTRALE (retargeting), and to measure the effectiveness of our advertising campaigns.

• Pixel Meta (Facebook) : enables advertising targeting and conversion measurement on meta platforms (Facebook, Instagram)
• Google Ads : It measures conversions from Google Ads campaigns and enables remarketing.
• Social media cookies: social media sharing buttons (Facebook, Instagram, Pinterest) that may place tracking cookies
• Cookie d'affiliation : allows you to identify visitors coming from affiliate partners and attribute conversions

The table below lists the main cookies used on the MACENTRALE website, their purpose, their publisher and their retention period:

This list is subject to change based on website updates and the tools used. We are committed to keeping this table up to date.

Some cookies on the MACENTRALE website are placed by third-party partner companies, independent of MACENTRALE Sàrl. These third parties place their cookies directly on your device when you visit our site, according to their own privacy policies.

MACENTRALE Sàrl has no direct control over the cookies placed by these third parties. We encourage you to consult the privacy policies of these companies to understand how they process your data:

• Google (Analytics & Ads) : policies.google.com/privacy

• Brevo (emailing) : brevo.com/fr/legal/privacypolicy

If you disagree with the practices of these third parties, you have the option to refuse their cookies via our consent manager or directly via your browser settings.

The shelf life of a cookie varies depending on its nature and purpose. There are two main categories:

• Session cookies: These cookies are temporary and are automatically deleted from your device when you close your browser. They are not stored permanently on your device.
• Persistent cookies: These cookies remain on your device until their expiration date or until you manually delete them. Their lifespan is defined by the cookie provider and can vary from a few minutes to several years.

In accordance with the recommendations of the Luxembourg CNPD and the guidelines of the European Data Protection Board (EDPB), the maximum retention period applicable to cookies subject to consent on the MACENTRALE website is 13 months from the date the cookie is placed. After this period, your consent is automatically requested again.

You have several options for managing your cookie preferences:

When you first visit the MACENTRALE website, a cookie management banner will appear. You can change your preferences at any time by accessing the consent manager available at the bottom of each page of the site (link "Manage my cookies"). This manager allows you to accept or reject each category of cookies individually.

• Meta Disable: via the advertising settings of your Facebook/Instagram account
• Initiative Your Online Choices : youronlinechoices.eu — a tool to disable advertising cookies from multiple ad networks in a single interface

You can configure your internet browser to accept or reject cookies, or to alert you before a cookie is placed on your device. Each browser offers different settings. Here are links to the help pages of the main browsers:

Please note that cookie settings are specific to each browser and device. If you use multiple browsers or devices, you will need to repeat your choices on each one.

You are free to refuse all or some non-essential cookies. However, refusing certain cookies may affect your browsing experience and your use of the site:

• Refusal of strictly necessary cookies (via browser settings only): the site may no longer function correctly. You may no longer be able to log in to your account, maintain your shopping cart, or place an order.
• Refusal of functional cookies: Some customizations will not be saved (language, currency, favorites). You will need to reconfigure your preferences each time you visit.
• Refusal of analytical cookies: We will not be able to measure site traffic or improve its usability based on actual browsing data. This does not affect your browsing experience.
• Refusal of marketing cookies: You will still see advertisements, but they will not be tailored to your interests and may be less relevant to you.

MACENTRALE Sàrl undertakes not to make access to the site or its essential services conditional on the placement of unnecessary cookies.

This Cookie Policy may be modified at any time, in particular to comply with legislative and regulatory developments (European directives, CNPD recommendations), to integrate new tools or partners, or to reflect changes in our practices.

In the event of a substantial change, we will inform you by posting a visible notification on the website and/or by email if you have a customer account. We will obtain your consent again if the new processing purposes require it. The current version is always the one published online, identifiable by its update date.
