M Chowdhury Online Studies ("we", "our", or "us") operates the MCA B2 mobile application (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.
a. Guest Access
If you use the App as a guest, you are not required to provide any personal identification information (such as your name or email). You can access freely available study resources directly.
b. Registered User Account Information
If you choose to log in to access full features and track your study progress, authentication is handled securely through our web platform. We may store:
Account credentials (email address / username and encrypted password)
Learning progress data (completed lessons, practice quiz scores, study history)
c. Device and Technical Information
The App does not collect sensitive device identifiers, GPS location, contacts, or media stored on your device. We only process technical data required for normal network communication and app functionality (such as network connection state to verify internet connectivity).
We use the collected information strictly for:
Authenticating registered users
Tracking and saving your exam preparation progress
Providing access to study materials and tests
Ensuring proper connectivity and performance of the App
The App does not sell products, services, or digital items inside the mobile application. No credit card or financial billing information is collected or processed by this App.
To protect educational course content from unauthorized distribution, the App utilizes Android system security flags (FLAG_SECURE). This prevents screen capture, screenshots, and screen recording while using the application. The App does not access your camera, microphone, or storage for this purpose.
We do not sell, trade, or rent your personal data to third parties. We do not use third-party behavioral advertising or data-broker SDKs in the App.
All data transmissions between the App and our servers are encrypted using standard Secure Sockets Layer / Transport Layer Security (HTTPS/TLS). While no transmission method over the internet is 100% secure, we implement commercially acceptable administrative and technical measures to protect your information.
You may request the deletion of your account and associated study data at any time by contacting us at the contact details below. Once verified, your account records and progress history will be permanently deleted from our servers.
Our services are intended for individuals preparing for B2 examinations and adult study qualifications. We do not knowingly collect personal identifiable information from children under the age of 13.
We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
If you have any questions or concerns about this Privacy Policy, please contact us:
