Cookie Policy

Last updated: April 2026

We use a single cookie to maintain your session. That's it.

What Cookies We Use

We use exactly one cookie: 'visitor_id' — an HttpOnly, Secure cookie that contains a random identifier. This cookie is essential for the platform to function (tracking your course progress, quiz attempts, and voting eligibility). It expires after one year.

No Tracking Cookies

We do not use any analytics cookies, advertising cookies, social media tracking pixels, or third-party cookies of any kind. We do not use Google Analytics, Facebook Pixel, or any similar service.

Theme Preference

Your dark/light theme preference is stored in browser localStorage (not a cookie). This data never leaves your device.

Managing Cookies

You can delete the visitor_id cookie at any time through your browser settings. This will disconnect you from your current session, but you can log back in with your passkey.
