Grammar Campus ("the App") is developed by Mainul App Store. We are committed to providing a high-quality educational experience for English learners without compromising user privacy. This policy explains our "Privacy by Design" approach, ensuring that your learning journey remains private and secure.
Grammar Campus is designed as an offline educational tool.
No Personal Information: We do not collect names, email addresses, phone numbers, or any other personally identifiable information (PII).
No Account Required: You can access all grammar topics, essays, CV templates, and dictionary features without creating an account or logging in.
No Tracking or Analytics: The App does not use third-party tracking, profiling, or analytics SDKs (such as Firebase or Google Analytics).
To provide a fast and reliable experience, the App stores educational content locally on your device.
Realm Database: We use the Realm database to store and organize grammar lessons and your Quiz results locally. This data never leaves your device and is not accessible by us.
Dictionary Cache: Dictionary definitions are stored locally for instant access.
Data Persistence: Your Quiz scores and learning progress are stored only on your phone. If you clear the App data or uninstall the App, this progress is permanently deleted.
The App requests the minimum necessary permissions to function:
Storage Access: Used only to allow the App to read its internal database and assets. We do not access your personal photos, videos, or external files.
Network Status: Used solely to detect if a connection is available for external links (like "Contact Us") but is not used for data transmission.
Grammar Campus is an educational app suitable for users of all ages. Because we do not collect any personal data, maintain accounts, or track users, the App is fully compliant with the Children’s Online Privacy Protection Act (COPPA) and GDPR standards for children’s safety.
The App uses reputable libraries to enhance the user experience. None of these are configured to collect or transmit user data:
Realm-Android
GSON/OkHttp
AndroidX/Material Components
