Privacy Policy for MathHub

Last Updated: July 13, 2026

Introduction

This Privacy Policy describes how MathHub ("we," "our," "the App") handles information when you use our mobile application. We are committed to protecting your privacy. Please read this policy carefully to understand our practices.

Information We Collect

MathHub does not collect, transmit, or share any personal data with us or any third party.

The App is designed to work completely offline. Specifically:

• We do not collect your name, email address, phone number, or any other personal identifiers.

• We do not collect location data.

• We do not use analytics, tracking, or advertising SDKs.

• We do not require account creation, login, or registration.

• We do not have servers that receive or store your data.

• We do not use cookies or similar tracking technologies.

Data Stored on Your Device

The App stores the following information locally on your device only, using local database (SQLite) and local storage technologies:

• Calculation history — records of calculations you perform and choose to save (e.g., tip calculations, loan EMI results, tax calculations, GPA sessions, age calculations, etc.)

• App preferences — your settings such as haptic feedback preference, sound preference, and default angle unit

• User-entered reference values — such as a gold price you manually enter for the Gold Price Calculator, saved for your convenience

This data:

• Never leaves your device

• Is not accessible to us, the developer, or any third party

• Is fully under your control and can be deleted at any time through the App's Settings screen (Clear All History, Clear GPA Sessions)

• Is permanently deleted if you uninstall the App

Permissions

The App may request minimal device permissions (such as haptic/vibration feedback) that are strictly necessary for core functionality. The App does not request permissions for camera, microphone, contacts, location, or storage access beyond what the operating system requires for standard app operation.

Third-Party Services

MathHub does not integrate with any third-party analytics, advertising, or data-collection services. We do not sell, rent, trade, or share user data because we do not collect any data to begin with.

Children's Privacy

The App does not knowingly collect any personal information from anyone, including children under the age of 13 (or the applicable age in your jurisdiction). Since the App is fully offline and collects no personal data, it is safe for use by users of all ages.

Data Security

Because all data is stored locally on your device and never transmitted over the internet, there is no risk of data interception, server breach, or unauthorized third-party access to your information through our systems. The security of locally stored data depends on your device's own security features (such as screen lock or encryption).

Your Rights and Choices

Since we do not collect or hold any of your personal data on our servers, there is no data for us to provide, correct, or delete on your behalf. You have full control over your locally stored data at all times and may:

• View your calculation history within the App

• Delete individual history entries

• Clear all history or saved sessions via Settings

• Uninstall the App to remove all associated local data permanently

Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in the App's functionality or for legal and regulatory reasons. Any changes will be posted with a revised "Last Updated" date. Continued use of the App after changes are posted constitutes acceptance of the updated policy.
