Privacy Policy

1 Introduction

AI Calculator Pro ("we", "our", or "the app") is a calculator application developed for Android devices. This Privacy Policy explains how we handle information when you use our app.

We are committed to protecting your privacy. This policy is written in plain language so you understand exactly what happens with your data.

2 Information We Do NOT Collect

We do not collect, store, or transmit:

• Your name, email address, or any personal identifiers
• Your device's location
• Your phone number or contacts
• Photos, files, or media from your device
• Usage analytics or behavioral data
• Any information that could personally identify you

3 Data Stored on Your Device

The following data is stored locally on your device only using your device's storage. It never leaves your phone and we cannot access it:

• Calculation history — your recent calculations
• AI chat history — your previous conversations with the AI assistant
• App settings — your theme preferences, decimal precision, haptic settings
• Cached exchange rates — temporarily saved currency and gold prices (refreshed every 10 minutes)

You can delete all locally stored data at any time by clearing the app's data in your Android settings, or by using the clear history buttons within the app.

4 Internet Usage

The app connects to the internet only for the following specific purposes:

• AI Assistant: When you send a message to the AI assistant, your message is sent to Google's Gemini API to generate a response. This is processed by Google under their own privacy policy. We do not store, log, or have access to these conversations.
• Currency Converter: Live exchange rates are fetched from the Frankfurter API (frankfurter.app), an open-source, free exchange rate service. No personal data is sent.
• Gold & Silver Prices: Live metal prices are fetched from Gold API (gold-api.com). No personal data is sent.

All other features — the calculator, scientific mode, and all tools except those requiring live data — work entirely offline.

5 Third-Party Services

The app uses the following third-party services. Each has their own privacy policy:

• Google Gemini API — powers the AI assistant. Google's privacy policy applies to AI conversations.
• Frankfurter API — provides currency exchange rates. Open-source, no personal data collected.
• Gold API — provides live metal prices. No personal data collected.
• Google Play Services — for app distribution and updates.

6 Children's Privacy

AI Calculator Pro is suitable for all ages. We do not knowingly collect any personal information from children under 13. Since we collect no personal information from any user, this app is compliant with children's privacy regulations including COPPA.

7 Data Security

Since we do not collect or store any personal data on our servers, there is no risk of your personal information being exposed through our systems.

Data stored on your device (history, settings) is protected by your device's own security features (screen lock, encryption). We recommend keeping your device software updated and using a screen lock for best security.

8 Your Rights

Since we do not collect personal data, most data rights (access, deletion, portability) are automatically fulfilled. Specifically:

• Right to access: All your data is already on your device, fully accessible to you
• Right to deletion: Clear app data in Android settings at any time
• Right to portability: Your data is locally stored and under your full control

9 Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically.

Continued use of the app after any changes constitutes your acceptance of the updated policy.
