Last updated: March 2026

What we collect

We collect the minimum data needed to make the site work. Here is exactly what that means:

  • Account data: If you sign in with GitHub, we store your GitHub username, email, and profile image. This powers your profile page, progress tracking, and leaderboard entries.
  • Learning progress: Lesson completions, quiz scores, streak data, and challenge submissions. Stored in our database, tied to your account.
  • Newsletter subscription: Your email address if you subscribe. Managed through Resend. You can unsubscribe at any time from any email.
  • Comments: If you post comments on lessons, the comment text and your username are stored and publicly visible.
  • Analytics: We use Vercel Analytics and Speed Insights to understand page performance. These collect anonymized usage data (page views, load times). No personal data is tracked through analytics.

What we don't collect

  • We don't sell or share your data with third parties for advertising.
  • We don't use tracking pixels or retargeting cookies.
  • We don't store your GitHub password. Authentication uses OAuth tokens.
  • We don't track what code you write in the playground unless you submit a challenge.

Cookies

We use essential cookies for authentication sessions and theme preference (dark/light mode). No advertising or third-party tracking cookies are used.
