<h3>External Services</h3>
This plugin connects to an external service to fetch live currency exchange rates.

<li>Purpose: To retrieve up-to-date currency exchange rates for the converter.</li>
<li>Data Sent: The base currency code (e.g., USD, EUR) in each request. No personal or identifiable user data is sent.</li>
<li>Data Received: Exchange rates for multiple currencies, displayed in the converter widget/shortcode.</li>
<li>Privacy & Terms:
