1. What Are Cookies?

Cookies are small string files downloaded to your device when you browse websites. Cantarell Energy Corp and Cantarell Systems S.A.P.I de C.V. ("Cantarell OS") utilize cookies, web beacons, telemetry, and tracking pixels to ensure our high-frequency trading platform and logistics dashboards operate securely and performantly.

2. Why We Use Cookies

We employ cookies strictly for the following B2B and technical justifications:

Strictly Necessary/Essential: To authenticate your SaaS session strings across the React/FastAPI infrastructure, mitigating CSRF and XSS attacks. The platform cannot function without these.
Performance and Telemetry: To track API latency and load times globally (US to MX), ensuring our high-availability SLA.
Functional Preferences: To store your localized preferences, such as USD vs MXN currency toggles, or English vs Spanish user interface preferences.
Analytics: To understand how organizations navigate our terminal inventory screens, allowing us to optimize the UX.

4. Third-Party Integrations

Cantarell OS utilizes trusted third-party services that may independently set functional or analytical cookies. These include:

Stripe: Payment processor SDK cookies for multi-currency transactions.
Segment / Mixpanel: Product telemetry to monitor error rates during API routing.
Mapbox / Google Maps: Telematics APIs that occasionally utilize local storage for caching map tiles during fleet tracking.

5. Managing Consents & Disabling Cookies

Under both US laws (like CCPA) and Mexican data protection directives (LFPDPPP), you have the right to revoke consent for non-essential cookies.

When you first land on Cantarell OS, you are prompted to manage your cookie preferences through our consent banner. Alternatively, you can block third-party cookies directly through your browser (Chrome, Safari, Firefox).

⚠ Warning: Disabling "Essential" cookies via your browser strictly prohibits login authentication. You will be unable to access the Trading Dashboard, Fleet Maps, or Customs Documentation modules.
