Privacy Policy

Last updated: February 8, 2026

1. Introduction

Welcome to CrackQuiz. We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we handle your information when you visit our website and use our services.

2. Privacy-First Design with Hybrid Approach

CrackQuiz is designed with privacy as a core principle. We use intelligent strategies to minimize server-side data exposure while maintaining functionality for large files:

  • Small quizzes (<7KB compressed): Data is compressed and embedded in URLs - never touches our servers.
  • Large quizzes (>7KB compressed): Temporarily stored on secure third-party servers with automatic 5-minute expiration for automatic loading and sharing features only.

3. Cookies

We use cookies to ensure that we give you the best experience on our website. This typically involves:

  • Essential cookies: Necessary for the website to function (e.g., remembering your language preference).
  • Analytics cookies: Help us understand how you use our website so we can improve it.
  • Preference cookies: Remember your settings like theme (dark/light mode) and selected AI models.

4. Local Storage

We use your browser's local storage to save your preferences and quiz history directly on your device. This data never leaves your device. You can clear it anytime by clearing your browser cache or using the 'Clear Data' option in the app.

6. Third-Party Services

We support optional third-party AI providers (OpenAI, Groq, OpenRouter, Gemini). If you choose to use these services, your data (notes, code) will be sent directly from your browser to their APIs. We do not act as an intermediary for these requests. Your API keys are stored securely and locally on your device (IndexedDB) and are never sent to our servers. Please review the privacy policies of these providers to understand how they handle your data.

7. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
