1. INTRODUCTION

Welcome to Calculator Pro. We are committed to respecting and protecting your privacy. Calculator Pro ("we", "our", or "the App") is a paid premium mobile application available for purchase on the Google Play Store. This Privacy Policy explains how our App operates and handles information when installed on Android devices.

By purchasing and using Calculator Pro, you agree to the terms outlined in this Privacy Policy. Calculator Pro is engineered as a privacy-first, ad-free utility application designed to operate safely without harvesting or commercializing personal user data.

2. PAID APPLICATION & BILLING INFORMATION

Calculator Pro is a premium paid application requiring a one-time purchase from the Google Play Store to install:

- Payment Processing: All financial transactions, payment processing, billing, and purchase receipts are handled entirely by Google LLC through the official Google Play Store billing system.

- Zero Financial Data Access: Calculator Pro and its developers do NOT have access to, nor do we collect, store, or process your credit card details, debit card numbers, bank accounts, or personal billing addresses.

- Lifetime Access: Your initial purchase on the Google Play Store grants you full, lifetime access to all current and future calculators, currency rate updates, tools, and features without recurring subscriptions or hidden in-app purchases.

3. INFORMATION COLLECTION AND USE

Calculator Pro does NOT collect, harvest, store, or transmit any Personally Identifiable Information (PII) such as your real name, email address, physical address, phone number, contact list, photos, media files, or precise GPS location.

- Calculation Data & History: All calculations, history logs, and saved favorite items are processed strictly locally on your device. This data remains on your physical device and is never uploaded to any remote servers, cloud databases, or third-party tracking providers.

- App Preferences: Settings such as your preferred theme (Light/Dark/System), default currency selection, number formatting style (Indian/International), language preference, and haptic feedback toggles are stored locally using Android SharedPreferences.

- Data Deletion: You can clear your calculation history at any time directly within the App settings ("Clear History Data"), or wipe all stored preferences by clearing the App data in Android System Settings.

4. DEVICE PERMISSIONS

Calculator Pro requests minimal device permissions necessary for core functional operations:

- INTERNET ACCESS (android.permission.INTERNET): Required exclusively to fetch public live currency exchange rate updates for ISO 4217 currencies. Currency API calls contain zero user identification, device tracking tokens, or personal information.

- HAPTIC FEEDBACK (android.permission.VIBRATE): Required to provide optional tactile haptic vibration when tapping calculator keys and navigation buttons. Users can disable haptics anytime in the App Settings.

5. THIRD-PARTY SERVICES AND ANALYTICS

Calculator Pro is 100% ad-free. We do NOT integrate third-party user tracking SDKs, data brokers, advertising networks, or behavioral analytics tools.

Standard system libraries provided by Google Play Services and Flutter framework may collect anonymous, aggregated diagnostic data (such as app crash logs or system performance metrics) strictly to maintain application stability and device compatibility.

6. CHILDREN'S PRIVACY

Calculator Pro is a general audience utility application intended for users of all ages. We do not knowingly collect or solicit personal information from children under the age of 13 (or under 16 in certain jurisdictions). If you believe a child has provided us with personal information, please contact us immediately so we can take appropriate measures to delete it.

7. DATA SECURITY

We value your trust in using Calculator Pro. Because all your calculation history and app settings remain strictly on your local device storage, your data benefits from Android's built-in sandbox security architecture. No external party or remote server has access to your calculations.

8. CHANGES TO THIS PRIVACY POLICY

We may update our Privacy Policy from time to time to reflect app improvements or legal requirement changes. Any updates will be posted directly within the application repository and updated in the "Effective Date" at the top of this document. You are advised to review this Privacy Policy periodically.
