Privacy Policy

Effective Date: September 07, 2026

Welcome to Binary Calculator and Solution. Your privacy is of the utmost importance to us. This Privacy Policy outlines the types of information we do and do not collect, how we handle data, and your rights as a user of our application.

Full Privacy Commitment: We do not track your calculations. Every operation you perform—from binary addition to complex bitwise shifts—is processed locally on your processor. We have no access to your mathematical input or output.

1. Data Collection and Local Storage

Offline-First Architecture: The core logic of the application is designed to function entirely offline. We do not transmit your calculation data to any external server.

Local Database (Room DB): To provide features like Calculation History and Favorites, the app stores data in a private database on your device. This data is part of the application's local sandbox and is not accessible by other apps or our development team.

User-Initiated Export: If you choose to use the "Export History" feature, the app will generate a JSON file. You are in full control of where this file is saved and with whom it is shared.

2. Permissions Used

To provide a functional and reliable experience, the app requests the following permissions:

INTERNET: Required to load advertisements (via AdMob) and to initialize cloud-based notification services (via OneSignal).
ACCESS_NETWORK_STATE: Used to check for an active internet connection before attempting to load ads or check for app updates.
POST_NOTIFICATIONS: Allows the app to send you push notifications regarding educational tips, new features, and important application updates.

3. Integration of Third-Party Services

We utilize trusted third-party providers to enhance the app's functionality and support its continued development:

Google AdMob: We use AdMob to display advertisements. AdMob may collect and process device identifiers, location data (if permitted), and other technical logs to serve personalized ads and measure performance. For more details, visit Google's Privacy Policy.
OneSignal: We use OneSignal for push notifications regarding educational tips and app updates. OneSignal may collect anonymous device tokens and data to ensure notifications are delivered reliably. Review their policy at OneSignal Privacy.

4. Data Safety and Security

We implement industry-standard technical measures to protect any data handled by the app. All communications with third-party SDKs occur over encrypted HTTPS connections. Because your primary data (history/favorites) is stored locally, its security depends on the overall security of your Android device.

5. Data Subject Rights (GDPR / CCPA)

Regardless of your location, we respect your right to control your data:

Access & Portability: You can view all your stored data within the app's History and Favorites sections.
Erasure: You can delete individual records or clear your entire history at any time using the "Clear History" button in the Settings or History screen.
Opt-Out: You can disable personalized ads in your Android System Settings and turn off notifications in the app's Settings menu.

6. Children’s Privacy

Binary Calculator and Solution is an educational tool suitable for all ages. We do not knowingly collect personal information from children. If you are a parent and believe your child has provided us with personal information, please contact us immediately.

7. Contact Information

If you have any questions or feedback regarding this Privacy Policy, please contact us using the support email address provided in our official Google Play Store listing.
