1. Information We Collect

We collect the following types of information:

  • Account information: When you create an account, we collect your name, email address, and authentication credentials.
  • Payment information: When you subscribe to Pro, payment is processed by Stripe. We do not store your full credit card number. We receive limited billing details (e.g., last four digits, expiration date) from Stripe.
  • Usage data: We collect information about how you use the Service, including problems attempted, submissions, progress, and feature usage.
  • Device and log data: We automatically collect your IP address, browser type, operating system, and referring URLs when you access the Service.
  • Local storage: We use browser local storage to save your work-in-progress code so it persists across page refreshes. This data is stored entirely on your device and is not transmitted to our servers.

  • To provide, maintain, and improve the Service
  • To process payments and manage subscriptions
  • To track your learning progress and provide personalized recommendations
  • To communicate with you about your account, updates, or support requests

3. How We Share Your Information

We do not sell your personal information. We may share information with:

  • Service providers: Third parties that help us operate the Service (e.g., Stripe for payments, Vercel for hosting, analytics providers).
  • Legal requirements: When required by law, regulation, legal process, or governmental request.
  • Business transfers: In connection with a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction.

4. Cookies and Tracking

We use cookies and similar technologies for authentication, preferences, and analytics. Essential cookies are required for the Service to function. You can control cookie preferences through your browser settings, though disabling certain cookies may affect functionality.

5. Data Retention

We retain your personal information for as long as your account is active or as needed to provide the Service. If you delete your account, we will delete or anonymize your personal information within a reasonable timeframe, except where retention is required by law.

6. Data Security

We implement reasonable technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
