Cookie Policy

Effective Date: October 16, 2026 | Last Updated: October 16, 2026

Introduction

This Cookie Policy explains how Zentradix ("we," "us," or "our") uses cookies and similar tracking technologies on our website and service. By using our platform, you consent to the use of cookies as described in this policy.

What Are Cookies?

Cookies are small text files stored on your device (computer, tablet, or mobile) when you visit a website. They help websites remember your preferences, improve performance, and provide analytics.

Cookies can be:

  • Session cookies: Temporary cookies that expire when you close your browser
  • Persistent cookies: Remain on your device for a set period or until manually deleted
  • First-party cookies: Set by Zentradix directly
  • Third-party cookies: Set by external services we use (e.g., analytics providers)

Cookies We Use

1. Essential Cookies (Required)

These cookies are necessary for the Service to function and cannot be disabled. They enable core features like:

  • Authentication: Keeping you logged in to your account
  • Security: Protecting against cross-site request forgery (CSRF) attacks
  • Session management: Maintaining your session state as you navigate the app
  • Preferences: Remembering your theme (light/dark mode), timezone, and accent color choices

Examples:

  • sb-access-token (Supabase authentication)
  • sb-refresh-token (Supabase session refresh)
  • theme (your chosen theme preference)
  • accent (your accent color preference)

Legal basis: Legitimate interest (required for service functionality)
Retention: Session cookies expire when you log out; persistent cookies expire after 7-30 days

Other Tracking Technologies

Local Storage

We use browser local storage (a technology similar to cookies) to store:

  • User preferences (theme, language, date format)
  • Temporary form data to prevent data loss during navigation
  • Application state for faster loading

Local storage data remains on your device until you clear it manually or we programmatically remove it.

Session Storage

Session storage holds temporary data that is deleted when you close your browser tab. We use it for:

  • Multi-step forms (e.g., trade entry wizard)
  • Temporary UI state (e.g., open/closed panels)

Third-Party Services & Their Cookies

We use the following third-party services that may set their own cookies:

Supabase (Authentication & Database)

  • Cookies: sb-access-token, sb-refresh-token
  • Purpose: User authentication and session management
  • Privacy Policy: Supabase Privacy Policy

Netlify (Hosting)

  • Cookies: _netlify_* (if forms/functions are used)
  • Purpose: CDN routing and form submissions
  • Privacy Policy: Netlify Privacy Policy

Paddle (Payments)

  • Cookies: Set during checkout flow
  • Purpose: Payment processing, fraud detection, session management
  • Privacy Policy: Paddle Privacy Policy

Managing Your Cookie Preferences

Browser Settings

You can control cookies through your browser settings. Most browsers allow you to:

  • View and delete cookies stored on your device
  • Block all cookies or only third-party cookies
  • Receive notifications when cookies are set

Learn how to manage cookies in popular browsers:

Note: Blocking essential cookies will prevent you from using Zentradix (you won't be able to log in or save data).

Do Not Track (DNT)

Some browsers offer a "Do Not Track" (DNT) signal. Currently, there is no industry-wide standard for DNT, so we do not respond to DNT signals. However, you can block analytics cookies using our Cookie Preferences tool or browser settings.

Data Retention

Cookie retention periods vary by type:

  • Session cookies: Deleted when you close your browser
  • Authentication cookies: Expire after 7-30 days or when you log out
  • Preference cookies: Persist for 1 year or until you change settings
  • Analytics cookies (if used): Up to 2 years (or sooner if you opt out)

Updates to This Policy

We may update this Cookie Policy to reflect changes in our practices or legal requirements. When we make material changes, we will:

  • Update the "Effective Date" at the top of this page
  • Notify you via email or a notice on the Service (for significant changes)

Continued use of the Service after changes constitutes acceptance of the updated policy.
