Privacy-Policy

1. What We Collect

When you use Nexray, we may collect:

• Account data — name, email, profile photo (if you sign in with Google)
• Progress data — which stages you've completed, stored locally and in Firebase
• Usage data — pages visited, time on page (via Google Analytics 4)
• Device data — browser type, OS, screen size (anonymized)

2. How We Use Your Data

• To provide and improve the educational service
• To save and sync your learning progress across devices
• To understand how users interact with the guide (analytics)
• To send occasional product updates (only if you opt in)

3. Google Sign-In

We use Firebase Authentication by Google for sign-in. When you sign in with Google, Google shares your name, email, and profile photo with us. We do not receive your Google password. Google's Privacy-Policy applies to that process.

4. Analytics

We use Google Analytics 4 to understand site usage. GA4 uses cookies and collects anonymized usage data. You can opt out via your browser's privacy settings or by using browser extensions like uBlock Origin.

5. Cookies

We use minimal cookies:

• Theme preference — stored in localStorage (not a cookie, stays on your device only)
• Session cookies — from Firebase Authentication, required for sign-in
• Analytics cookies — from Google Analytics (can be blocked)

6. Data Sharing

We do not sell your personal data. We share data only with:

• Firebase/Google — for authentication and data storage
• Google Analytics — for anonymized usage analytics

7. Your Rights (GDPR)

If you are in the EU/EEA, you have the right to access, correct, or delete your personal data. Email dev@nexray.in to exercise these rights.

8. Data Retention

Account data is retained as long as your account exists. Progress data in localStorage is stored on your device until cleared. You can delete your account at any time from your profile page.
