Privacy Policy for Number System

1. Overview

Number System is a utility and learning app for converting numbers between Binary, Octal, Decimal and Hexadecimal. The core purpose is calculation, copy-friendly output and educational explanation. Users can use the app for learning number systems, study work, programming examples, digital electronics practice and software-related number formats.

2. Information we do not ask for

The app is designed as a simple converter and guide. It does not require users to create an account to perform number conversion. The app does not request personal identity information such as name, address, government ID, date of birth or payment card information for its basic conversion purpose.

3. App data and user inputs

When users type numbers into the converter, those values are used to generate conversion results on the device. Number inputs are ordinary calculation data and should not be used to store secrets, passwords, private codes or personal information.

4. Permissions

Number System should only request permissions needed for its app features. If a future version adds additional features that need permissions, this policy and the Google Play Data safety information should be updated to explain the purpose clearly.

5. Third-party services

Google Play may provide app listing, installation, update and platform services. If the app uses analytics, crash reporting, ads or other third-party services in a future release, the Play Store listing and this policy should disclose those services and their data handling purpose.

6. Children and students

The app may be useful for students learning number systems. It is not intended to collect personal data from children. Parents, guardians and teachers should guide younger users to avoid entering private or sensitive information into any utility app.

7. Data retention

For normal converter usage, the app does not need a user account or cloud profile. If any local preferences such as default input base, digit grouping or theme are saved, they are kept for app functionality and can be changed through app settings or removed by clearing app data from Android settings.

8. Security

Apps Bean Technologies aims to keep the app simple and secure. Users should install the app only from official distribution channels such as Google Play to reduce the risk of modified or unofficial copies.

9. User choices

Users can stop using the app at any time. They can uninstall it from the device through Android settings or Google Play. For support questions, users can email the developer.

10. Contact for privacy questions

For privacy, support or app listing questions, contact Apps Bean Technologies by email at info@appsbean.com. Email communication is the preferred support channel for this app.

11. Policy updates

This Privacy Policy may be updated when app features, permissions, third-party services or Google Play requirements change. Continued use of the app after an update means the user accepts the updated policy.
