Currency Converter Privacy Policy

Effective date: July 21, 2026

Currency Converter provides exchange-rate calculations and optional cloud synchronization.

Information we process

• Email address, display name, and user identifier when you choose to sign in.
• Your selected currency codes and preferences, stored locally and synchronized with Firebase when you are signed in.
• Technical information used for advertising, consent, diagnostics, and app operation.
• Subscription status and purchase identifiers processed by Google Play, Apple, and RevenueCat. We do not receive complete payment card details.

How information is used

Information is used to provide conversions, restore preferences across devices, authenticate accounts, show ads to non-subscribers, manage subscriptions, prevent abuse, and improve reliability. Exchange rates are obtained from open.er-api.com.

Service providers

The app uses providers including Google Firebase, Google AdMob, RevenueCat, Google Play, Apple App Store, and open.er-api.com. They process information under their own terms.

Advertising and choices

Where required, the app asks for consent before requesting ads and provides an in-app entry point to change applicable privacy choices. Subscribers do not receive ads. Google AdMob collects your device's advertising identifier (Advertising ID on Android, IDFA on iOS) along with device and diagnostic information, and shares it with advertising partners to select the ads shown. You can reset or delete that identifier in your device settings.

Retention, deletion, and rights

Data is kept only as needed for the service and legal or security purposes. You may request access, correction, or deletion by contacting fhmarriapps@gmail.com.

Children and security

The app is not directed to children under 13. We use reasonable safeguards, but no electronic service is completely secure.
