Privacy Policy

Currency Converter · Last updated: June 2, 2026

Live foreign-exchange rates and a fast converter. This policy explains what data Currency Converter does and doesn't handle.

Summary

Your settings and saved currencies stay on your device. We collect a limited amount of diagnostic and usage data to keep the app reliable, and we show ads through Google AdMob.

Information processed on your device

• Preferences — your selected currencies, favourites, and display settings are stored locally on your device.

Information we collect

To keep Currency Converter reliable we collect a limited amount of data through Google Firebase. It is used in aggregate to fix bugs and improve the app, and is not used to personally identify you:

• Crash & performance diagnostics — via Firebase Crashlytics and Performance Monitoring, to detect and fix problems.
• Anonymous usage analytics — via Firebase Analytics, to understand which features are used. This is aggregated and not used to identify you.

Exchange rates are fetched from third-party rate providers over the internet. Only the currency pair is requested — never anything that identifies you.

Advertising (Google AdMob)

Currency Converter shows ads via Google AdMob. To serve ads, Google may collect and process device identifiers (including the advertising ID), IP address, and ad-interaction data, as described in How Google uses information from sites or apps that use our services and the Google Privacy Policy.

Your choices & consent

• In the EEA, UK, and Switzerland we request consent for personalized ads through Google's certified consent flow (UMP) on first launch.
• You can reset your advertising ID or opt out of ad personalization in your device settings.

In-app purchases

Currency Converter may offer optional in-app purchases (for example, to support development). Payments are handled entirely by the Apple App Store or Google Play; we never receive or store your payment details.

Third-party services

• Google Firebase (Crashlytics, Analytics, and related services) — Firebase privacy & security
• Google AdMob — Google Privacy Policy
• Apple App Store / Google Play — payment processing for in-app purchases

Children

Currency Converter is a general-audience app and is not directed to children under 13. We do not knowingly collect data from children.

Data security & retention

Data stored on your device is protected by your device's own security and is removed when you delete it or uninstall the app. Diagnostic and analytics data is retained by Google/Firebase according to their policies.

Changes

We may update this policy; material changes are reflected by the "Last updated" date above.
