Privacy Policy

1. Introduction

Welcome to Calculator ("we", "our", or "the application"), developed and maintained by Jiyainfotech. This Privacy Policy governs your use of the Calculator Android application (Package Name: com.calculator.math.number.tools).

We respect your privacy and are committed to protecting it through complete transparency. This policy outlines how information is handled when you download, install, and use our application.

2. Information Collection and Storage

We believe your calculations and daily calculations belong only to you. Our application operates under the following data handling standards:

• No Personal Information: We do not ask for or collect names, email addresses, phone numbers, postal addresses, or any personal identifiers.
• No Financial or Payment Information: Any price, discount, or tax calculations you perform are processed strictly locally in your device's memory and are never uploaded or linked to your identity.
• No Device or Hardware Identifiers: We do not read, gather, or transmit IMEI numbers, Android Advertising IDs (AAID), MAC addresses, or SIM details.
• No Location Data: The application does not request, access, or track GPS coordinates or network-based location data.

3. Local Data Storage & Calculation History

To provide a helpful user experience, Calculator saves recent calculation results (such as arithmetic expressions and calculation history) locally on your device's private storage using Android's encrypted sandboxed preferences:

• On-Device Only: Calculation history remains solely on your physical device.
• User Control: You have full control to clear your calculation history at any time using the "Clear All" button inside the Recent Calculations screen.
• Uninstall Deletion: If you uninstall the application, all locally saved calculations and preferences are automatically deleted by the Android operating system.

Calculator requires zero sensitive or dangerous permissions to function. Below is the full permission transparency overview:

5. Third-Party Services & Advertising

We believe in an uninterrupted, clean user experience:

• No Third-Party SDKs: We do not integrate third-party analytics (such as Google Analytics or Firebase Analytics) or crash tracking SDKs that transmit data.
• No Advertisements: The application does not contain advertising banners, interstitial ads, or tracking identifiers.
• No Data Brokers: We do not sell, rent, or trade any user information to third-party data brokers or marketing entities.

6. Children's Privacy (COPPA & Families Policy)

Calculator is safe for all audiences, including children and families. It complies fully with the Children's Online Privacy Protection Act (COPPA) and the Google Play Families Policy:

• We do not knowingly collect personal information from children under 13 (or under 16 in applicable jurisdictions).
• The app contains no age-inappropriate content, advertisements, or external tracking mechanisms.

7. Security Practices

Because Calculator operates locally without transmitting data over the Internet or connecting to cloud servers, your information is protected by Android's built-in application sandboxing architecture. No user data leaves your physical device.

8. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect updates to the app or legal obligations. Any updates will be published on this page with an updated revision date. We encourage you to review this policy whenever you update the application.
