Privacy Policy - Physics Pocket

Summary: Physics Pocket is a 100% offline educational application. We do not collect, transmit, store, sell, or share any personal data, device identifiers, or usage telemetry. The app requires zero Android permissions (no INTERNET permission) and functions completely in Airplane Mode.

1. Introduction

This Privacy Policy explains how Physics Pocket ("we", "our", or "the application") respects and protects the privacy of its users. Physics Pocket is an educational reference handbook and practice application designed for school students, college learners, and competitive exam aspirants.

Our fundamental design principle is complete user privacy and autonomy. The application operates solely on your local device without any backend servers, online databases, or third-party web services.

2. Data Collection and Usage

Physics Pocket does not collect any personal data. Specifically:

No Personal Identifiers: We do not collect your name, email address, phone number, location, or physical address.
No Account Required: There is no registration, login, profile creation, or authentication mechanism.
No Device Information: We do not capture your IP address, IMEI, MAC address, Android Advertising ID, or hardware characteristics.
No Usage Tracking or Telemetry: We do not track which screens you view, which questions you answer, or how long you use the application.
No Cookies or Local Tracking Beacons: No cookies, pixel tags, or web trackers are utilized.

3. Application Permissions

Physics Pocket adheres to the principle of least privilege. In fact, the application requests zero runtime or install-time permissions:

Permission	Status	Rationale
`android.permission.INTERNET`	NOT REQUESTED	The app cannot make network calls or transmit data over the internet.
`android.permission.ACCESS_NETWORK_STATE`	NOT REQUESTED	The app has no awareness of network connectivity.
`android.permission.READ_EXTERNAL_STORAGE`	NOT REQUESTED	No access to device files or photos.
`android.permission.ACCESS_FINE_LOCATION`	NOT REQUESTED	No geographic location tracking.

4. Local Storage and Data Retention

All data generated while using Physics Pocket remains strictly on your local device:

Bookmarks: Saved topics, key formulas, and bookmarked questions.
Learning Progress: Completed topic checkmarks and accuracy percentages.
Quiz Records: Local score history and timestamp of completed practice sessions.
User Preferences: Theme selection (Light/Dark/System) and haptic feedback toggles.

This data is stored using Android's private SharedPreferences and is isolated in the app's internal sandbox. No other application on your device can access this data.

You can permanently delete all locally stored data at any time via Settings > Local Storage & Archive > Reset Academic Ledger, or by uninstalling the application or clearing app data through Android system settings.

5. Third-Party Services and SDKs

Physics Pocket contains NO third-party software development kits (SDKs) for advertising, analytics, crash reporting, or user tracking:

No Google AdMob, Unity Ads, or advertising networks.
No Google Analytics, Firebase Analytics, or Mixpanel.
No Crashlytics or Sentry telemetry.
No social media integrations (Facebook SDK, Twitter/X SDK).
No cloud backend integrations (Firebase, Supabase, AWS Amplify).

6. Children's Privacy (COPPA & GDPR-K Compliance)

Physics Pocket is suitable for learners of all ages, including children under the age of 13 (or under 16 in the European Union). Because our application does not request internet access and collects zero personal information, it complies fully with the Children's Online Privacy Protection Act (COPPA) and the General Data Protection Regulation (GDPR).

Parents and guardians can be confident that their children can study physics safely without privacy risks, targeted advertisements, or commercial data collection.

7. Google Play Families Policy Compliance

Physics Pocket complies with Google Play's Families Policy Requirements:

The application contains no ads of any kind.
The application does not collect any personal or sensitive information.
The application does not request the Android Advertising ID (AAID).
All content is educational, academic, and age-appropriate.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect future software updates or changes in legal regulations. Any revisions will be published with an updated "Last Updated" date. Because the app operates offline, we encourage users to review this page periodically.
