Last updated: February 2026

This Cookie Policy explains what cookies are, how NSKAI uses them on the ZERRA platform, and what choices you have regarding their use.

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, keep you signed in, and understand how you interact with the platform.

Types of Cookies We Use

Essential Cookies (Required)

These cookies are necessary for ZERRA to function properly. They enable core features such as:

  • User authentication and session management via Clerk.
  • Remembering your role (Learner, Tutor, or Admin) across pages.
  • Maintaining security and preventing unauthorized access.
  • Remembering your theme preference (light/dark mode).

These cookies cannot be disabled as they are essential to the platform's operation.

Analytics Cookies (Optional)

These cookies help us understand how visitors interact with ZERRA so we can improve the platform. They collect anonymized data such as:

  • Pages visited and time spent on each page.
  • Navigation patterns and feature usage.
  • Error occurrences and performance metrics.

We use Sentry for error tracking and performance monitoring. These cookies do not collect personally identifiable information.

Preference Cookies (Optional)

These cookies allow the platform to remember choices you make, such as:

  • Display preferences and UI settings.
  • Last-visited course or lesson for the continue-learning feature.
  • Language and regional preferences.

Third-Party Cookies

Some cookies are set by third-party services we use to operate ZERRA:

  • Clerk: Authentication and session management cookies.
  • Mux: Video player cookies for adaptive streaming and playback quality.
  • Sentry: Error tracking and performance monitoring cookies.

These third-party services have their own privacy and cookie policies, which we encourage you to review.

  • View what cookies are stored and delete them individually.
  • Block third-party cookies.
  • Block cookies from specific sites.

Please note that disabling essential cookies may prevent you from using ZERRA properly, including staying signed in and accessing your courses.
