Privacy Policy

1. Introduction

Natural Sciences (the "App") is developed for first-year Natural Sciences students to provide access to past papers, solutions, lecture materials, and offline study support. This Privacy Policy explains what information we collect, how we use it, and your rights.

2. Information We Collect

• Account Information (optional): If you create an account or sign in, we may collect your name and email address to associate saved content with your account.
• Content You Provide: Files, notes, uploaded questions, images, or links you store in the app for offline use.
• Usage Data: Analytics related to app usage (pages viewed, features used, crash reports). This helps us improve the app.
• Device Information: Device model, OS version, and app version for troubleshooting and analytics.

3. How We Use Your Information

We use collected information to:

• Provide and maintain app functionality (saving files for offline use, delivering content).
• Improve the app through analytics and crash reports.
• Communicate with you about updates or support if you contact us.

4. Local & Offline Data

Files you save for offline use (PDFs, images, videos) are stored on the device. These files remain under the user's control and are not uploaded unless you explicitly choose to sync or back them up using an account or third-party service.

5. Third-Party Services

We may use third-party services for analytics and crash reporting (for example, Google Analytics for Firebase or similar). These services collect aggregated usage information to help us improve performance. Links to YouTube videos embedded in the app are served by Google/YouTube and may collect information according to their privacy policies.

6. Data Sharing & Disclosure

We do not sell your personal information. We may share information with service providers who help operate the app (hosting, analytics). We may also disclose information if required by law or to protect rights and safety.

7. Security

We follow standard security practices to protect data, but no method of transmission or storage is 100% secure. Please keep backups of important materials you upload.

8. Children's Privacy

Our app is intended for students in higher education. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, contact us and we will take steps to delete it.

9. Your Rights

Depending on your location, you may have rights to access, correct, or delete your personal data. To exercise these rights, contact us using the details below.

10. Changes to This Policy

We may update this policy from time to time. The "Effective date" at the top will reflect the latest revision. We encourage you to review it periodically.
