How It Works: Live Currency Converter Pro fetches official exchange rates from trusted European Central Bank data and merges crypto prices from a reliable source. Rates are cached locally to allow offline use and fast access. Users can refresh rates on demand or at app launch. The fee slider models real-world transaction costs by reducing converted amounts accordingly.

• Users tracking currency trends with historical charts.
• Anyone calculating tips and splitting bills in foreign currencies.

Privacy Notes: The app accesses live exchange rate APIs only when refreshing data. All rates and user preferences are stored locally on the device and shared securely with the widget extension via app group storage. No personal user data is collected or transmitted.
