Universal Currency Converter Lite

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

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

Shortcode

Use:
[univcuco_converter]

Override defaults per instance:
[univcuco_converter default=”EUR” to=”GBP” amount=”10″ decimals=”2″]

External Services

This plugin connects to an external service to fetch live currency exchange rates.

• Service Used: ExchangeRate-API (https://open.er-api.com/)
• Purpose: To retrieve up-to-date currency exchange rates for the converter.
• Data Sent: The base currency code (e.g., USD, EUR) in each request. No personal or identifiable user data is sent.
• Data Received: Exchange rates for multiple currencies, displayed in the converter widget/shortcode.
• Privacy & Terms:
  • Terms of Service: https://www.exchangerate-api.com/terms
  • Privacy Policy: https://www.exchangerate-api.com/privacy

This connection is required for the plugin to function. If the API is unavailable, live exchange rates will not be displayed.
