Cookies Policy

1. What Are Cookies?

Cookies are small files of numbers and letters stored on your local device (browser, tablet, or mobile phone) when you access our commercial web portals. They allow our systems to distinguish you from other users, providing seamless page navigation, retaining your preferred B2B configurations, and ensuring absolute security across our multi-subdomain routing architecture.

2. How We Use Cookies

We use cookies and similar web trackers to maintain server load-balancing, remember your language switcher selections (`fr.centurylabo.com`), support analytical diagnostics, and facilitate secure asynchronous form submissions to our robust PHP backends.

3. Categories of Cookies We Place

Our global portal deploys three primary categories of storage:

• **Strictly Necessary Cookies**: Essential for basic page functionality, secure B2B quote inquiries, and CORS runtime authentication. These cannot be disabled.
• **Performance & Analytics Cookies**: Allowed us to measure visitor interaction, page load speeds, and technical document access (such as digital COA/SDS downloads) in order to optimize infrastructure throughput.
• **Functional B2B Cookies**: Enabled specialized B2B personalization, remembering your commercial entity details and pre-filling your specific Contact Us preferences.

4. Managing Your Cookie Preferences

You can review, modify, or block cookies at any time by accessing your internet browser settings. You can wipe existing persistent cookies or instruct your browser to refuse all third-party scripts. Please be advised that disabling Strictly Necessary web cookies may adversely impact the functionality of our language router and custom quote modules.
