This Privacy Policy explains how Mastering NDA/NA English collects, uses and protects information when you use this website, create an account, attempt online practice tests or otherwise interact with our services.
1. Information you provide
When registration, login or profile features are used, we may collect information you provide, such as your name, email address and profile or class-related details. We also store information connected with your learning activity, such as quiz attempts, scores, accuracy, test duration and related progress information.
2. Automatically stored information
The website may use browser storage technologies such as local storage, session storage and cookies where necessary for login, preferences, test progress, security and site functionality. Standard technical information may also be processed by our hosting and service providers, such as browser type, device information, IP address, access time and requested pages.
3. How we use information
- To provide registration, login, user dashboard and practice-test functionality.
- To save and display test attempts, scores and learning progress.
- To maintain site security, diagnose technical problems and improve usability.
- To respond to queries or support requests.
- To measure site performance and, where enabled, support advertising and analytics.
4. AI study assistant and response assessor
When you use the AI Study Guide or submit typed or handwritten practice responses for AI feedback, the question or submitted response and limited page context are sent to the configured AI service through our backend to prepare a reply. The website does not store chat message text or uploaded answer files. It records the student account, time and limited usage metadata to enforce service limits. Draft responses may remain temporarily in your browser session until you open the assessor. Please do not submit passwords, OTPs or private personal information. AI replies are educational aids and may be inaccurate; review important information against course materials and official sources.
6. Supabase and service providers
Parts of the website use third-party infrastructure and services, including Supabase, for features such as authentication, data storage and related backend functions. Information processed through these services is handled subject to the relevant provider's terms and privacy practices.
6. Google advertising, cookies and identifiers
The website may use Google AdSense or other Google advertising services. Where advertising is enabled, Google and its advertising partners may use cookies or similar identifiers to serve, personalise, limit and measure advertisements, detect fraud and understand advertising performance. Users may be able to manage personalised advertising through Google's advertising settings and other consent controls made available on the site or by Google.
Where required by applicable law, including for users in regions requiring consent for advertising cookies or personalised ads, an appropriate consent-management mechanism may be presented before such technologies are used.
7. Third-party links
The website may contain links to external websites, official examination resources, marketplaces, videos or other third-party services. We are not responsible for the privacy practices or content of external websites.
8. Data retention and security
We retain information only for as long as reasonably necessary for the purposes described above, subject to operational, legal and security requirements. Reasonable safeguards are used to protect data, but no internet-based system can be guaranteed to be completely secure.
9. Your choices
You may choose not to provide optional information. Browser settings can be used to control cookies and local storage, although disabling required storage may affect login, dashboard or test functionality. Where advertising consent controls are available, you may use them to manage your advertising preferences.
10. Children's privacy
This website provides educational material that may be used by school students. Users should provide only the information reasonably necessary to use the educational features. Where parental or guardian consent is required by applicable law, users and guardians are responsible for complying with those requirements.
