Privacy Policy

📋 Information We Collect

React Mastery is committed to transparency about the data we handle. As a free, open-source educational platform, we collect minimal information necessary to deliver an optimal learning experience.

• Browser Preferences: Your selected theme (dark/light mode) is stored locally on your device using browser localStorage. This data never leaves your device.
• Usage Analytics: We may collect anonymized, aggregated data about page views and interactions to improve our content quality and user experience.
• Device Information: Standard technical data such as browser type, operating system, screen resolution, and language preferences may be automatically collected when you visit our pages.
• Donation Information: If you choose to support us via Razorpay or UPI, payment processing is handled entirely by third-party providers. We do not store credit card numbers or sensitive financial data on our servers.
• Contact Communications: If you reach out to us via email, we retain the communication to respond and improve our services.

🔧 How We Use Information

The limited information we collect serves specific, legitimate purposes aligned with delivering excellent educational content:

• Personalization: Remembering your theme preference ensures a consistent, comfortable browsing experience across visits without requiring you to reconfigure settings.
• Content Improvement: Anonymized usage data helps us understand which tutorials are most popular, where learners spend the most time, and how we can enhance our curriculum.
• Communication: Email correspondence is used solely to respond to your inquiries, provide support, and share updates if you've opted in.
• Security: Technical data helps us identify and prevent malicious activity, maintain site performance, and troubleshoot issues.
• Legal Compliance: We may use information as required by applicable laws and regulations to fulfill our legal obligations.

We never sell, rent, or trade your personal information to third parties for marketing purposes. Your trust is the foundation of our community.

🌐 Third-Party Services

React Mastery integrates with carefully selected third-party services to enhance performance and functionality. Each service has its own privacy practices:

• Google Fonts: We use Google Fonts to deliver high-quality typography. When you load a page, your browser may connect to Google's servers to download font files. Google may collect standard web server logs including IP addresses. Google's Privacy Policy →
• CDN Services: Content Delivery Networks (CDNs) are used to serve static assets (images, scripts) quickly from servers geographically closest to you. CDN providers may log access data for performance and security purposes.
• Razorpay (Donations): If you choose to make a voluntary donation, payment processing is handled by Razorpay, a PCI-DSS compliant payment gateway. Razorpay collects and processes your payment information under its own privacy policy. We receive only transaction confirmations — never your card details. Razorpay's Privacy Policy →
• GitHub: Our source code is hosted on GitHub. If you interact with our repository (star, fork, or contribute), GitHub's privacy policy governs that interaction. GitHub's Privacy Policy →

🍪 Cookies & Local Storage

React Mastery uses minimal client-side storage to enhance your experience. Here's a complete breakdown of what we store:

• Theme Preference (localStorage): We store your dark/light mode preference using the key reactMasteryTheme in your browser's localStorage. This is a simple string value ("dark" or "light") that persists between sessions.
• No Tracking Cookies: We do not set any tracking cookies, advertising cookies, or cross-site cookies. Your browsing activity on our site is not tracked for advertising purposes.
• Third-Party Cookies: Some third-party services (such as Google Fonts) may set their own cookies according to their respective policies. We have no control over these cookies.

🛡️ Data Security

We take the security of your information seriously and implement appropriate technical and organizational measures to protect it:

• HTTPS Encryption: All communications between your browser and our servers are encrypted using TLS/SSL protocols, ensuring data in transit is protected from interception.
• Minimal Data Collection: Our strongest security measure is collecting as little data as possible. Data that doesn't exist cannot be breached.
• Open Source Transparency: Our codebase is publicly available on GitHub, allowing security researchers and the community to audit our code for vulnerabilities and verify our privacy claims.
• Regular Updates: We keep all dependencies and third-party integrations updated to their latest secure versions to protect against known vulnerabilities.
• Secure Payment Processing: All donation transactions are processed through PCI-DSS compliant payment processors. We never handle or store sensitive financial data directly.

While no method of electronic transmission or storage is 100% secure, we strive to implement commercially reasonable measures to protect your data. If you discover a security vulnerability, please contact us immediately.

👶 Children's Privacy

React Mastery is an educational platform designed for learners of all ages interested in web development. We are committed to protecting the privacy of children:

• Our platform does not knowingly collect personal information from children under the age of 13 (or the applicable age in your jurisdiction).
• We do not require registration or account creation, which means children can access our educational content without providing any personal data.
• If we become aware that we have inadvertently collected personal information from a child under the relevant age threshold, we will take immediate steps to delete such information.
• Parents and guardians who believe their child has provided personal information to us should contact us immediately at one of the email addresses listed in the Contact section below.
