WPC Multi Currency for WooCommerce is a feature-rich currency conversion and switching system designed for global WooCommerce stores. Whether you sell to a handful of countries or worldwide, this plugin gives your customers the freedom to shop in the currency they know and trust — boosting conversion rates and reducing cart abandonment.

External services
Exchange Rate API
This plugin connects to the ExchangeRate-API service to fetch up-to-date currency exchange rates. This is required for the automatic rate update feature to work correctly.
When an admin clicks “Fetch Exchange Rates” or when a scheduled update runs, the plugin sends a request to: https://open.er-api.com/v6/latest/{BASE_CURRENCY}
No personal data or user information is transmitted. Only the store’s base currency code (e.g. “USD”) is included in the request URL.
This service is provided by ExchangeRate-API Ltd:

IP Geolocation API
This plugin also connects to the ipapi.co service to detect the visitor’s country by IP address. This is used only when the “GeoIP Auto-Detection” feature is enabled AND WooCommerce’s built-in geolocation returns no result. The result is cached for 24 hours to minimise external requests.
When a fallback lookup is needed, the plugin sends a request to: https://ipapi.co/{VISITOR_IP}/country/
The visitor’s IP address is transmitted as part of the request URL. No other personal data is sent. The response contains only a 2-letter ISO country code (e.g. “US”).
