Universal Currency Converter Lite lets you add a simple currency converter to any page or post using a shortcode. It fetches live exchange rates, allows you to set default and target currencies, and style the widget (background, button, text colors) from an admin settings page.
Features

<li>Live rates from ExchangeRate-API (relative to USD).</li>
<li>Shortcode to embed anywhere.</li>
<li>Admin page to choose default & target currencies.</li>
<li>Color pickers for background, button, and text colors.</li>
<li>Optional “Buy Me a Coffee” link inside the settings page (Paystack).</li>
</ul>

 [univcuco_converter]
Override defaults per instance:

<h3>External Services</h3>
This plugin connects to an external service to fetch live currency exchange rates.
<ul>
<li>Service Used: ExchangeRate-API (https://open.er-api.com/)</li>
<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:
<ul>
<li>Terms of Service: https://www.exchangerate-api.com/terms</li>
<li>Privacy Policy: https://www.exchangerate-api.com/privacy</li>
</ul>
</li>
</ul>
This connection is required for the plugin to function. If the API is unavailable, live exchange rates will not be displayed.
