Privacy Policy

This Privacy Policy explains how the B.Tech Engineering app by MS INVENTER handles information when you use the app.

1. Information the app does not ask you to provide

The app does not require account creation or sign-in. We do not ask you to provide your name, email address, phone number, precise or approximate location, payment information, financial information, photos, videos, audio files, contacts, calendar data, messages, or other user-submitted personal information.

2. Technical data processed automatically

The app uses Google Firebase Realtime Database to retrieve educational content such as subjects, topics, and links. When Firebase Realtime Database is used, limited technical information such as an IP address and user-agent information may be processed automatically. This technical information is used to understand usage trends and platform breakdowns and to operate and improve the service.

In Google Play's Data safety disclosure, this is represented as Device or other IDs collected for Analytics. The app does not use this information for advertising or marketing.

3. Educational content and PDF delivery

The app loads study material and PDF content through web services used by MS INVENTER, including Firebase-hosted services and Cloudflare-hosted content. These service providers may process standard network request information required to deliver content securely.

4. Advertising

The current version of the app does not contain advertising and does not use Advertising ID for advertising or marketing.

5. Sharing of data

We do not sell user data. We do not share user data with third parties for advertising or marketing. Service providers such as Google Firebase and Cloudflare may process limited technical data on our behalf as needed to provide their infrastructure and content-delivery services.

6. Security

Network communication used by the app and its online services is transmitted using secure HTTPS connections. We take reasonable steps to use reputable service providers and to limit data handling to what is required to operate the app.

7. Data retention and deletion

The app does not create user accounts and does not maintain a user profile or a database of user-submitted personal information. According to Firebase's documentation, Realtime Database keeps IP address and user-agent information for a few days by default unless the Firebase customer chooses to save it longer. MS INVENTER does not intentionally use this information to identify individual users.

Because the app does not maintain user accounts or user-submitted personal records, there is generally no account record to delete. If you have a privacy inquiry or believe information relating to you needs to be addressed, please use the developer contact details shown on the app's Google Play listing.

8. Children's privacy

The app is intended as an educational reference app. It does not knowingly ask children to submit personal information through an account or profile.

9. Third-party services

The app relies on third-party infrastructure, including:

• Google Firebase: Firebase Privacy and Security
• Cloudflare: Cloudflare Privacy Policy

10. Changes to this policy

We may update this Privacy Policy when the app, its features, or applicable requirements change. The latest version will be posted at this page.
