Privacy Policy
Last updated: December 2025
Thank you for using BioChemQuizApp ("the App"). This Privacy Policy explains how we collect, use, and protect your information. The App is designed to work primarily offline, providing AP Biology and Chemistry quiz practice using locally stored content.
Information We Collect
The App does not collect, store, or transmit any personal information about you. All quiz progress, scores, and results are stored locally on your device using standard iOS storage (UserDefaults) and are never shared with us or any third party.
No account registration, login, or personal data (such as name, email, location, or device ID) is required or collected.
Offline Functionality
The core features of the App (quizzes, progress tracking, and mixed tests) work completely offline. All questions and explanations are stored within the App and do not require an internet connection.
Internet Access and Third-Party Links
The App may optionally open external links to Khan Academy resources for further learning. These links require an active internet connection and will open in your device's default browser (Safari).
When you access Khan Academy:
We do not control or receive any data from Khan Academy.
Your interaction with Khan Academy is governed by Khan Academy's Privacy Policy: https://www.khanacademy.org/about/privacy-policy
No data is shared between the App and Khan Academy.
No Data Sharing or Third-Party Services
We do not use analytics, advertising, tracking, or any third-party services that collect user data. The App contains no ads, in-app purchases, or tracking technologies.
Children's Privacy
The App is intended for educational use and is suitable for users of all ages, including children under 13. Since no personal information is collected, the App complies with the Children's Online Privacy Protection Act (COPPA) and similar regulations.
Data Security
All data (quiz progress) is stored securely on your device only. You can delete the App at any time to remove all local data.
Changes to This Privacy Policy
