External services

This plugin relies on an external service to render the widget and to supply live exchange rates: Currency.Wiki , operated by CurrencyWiki Technologies LLC.

What the service is and what it is used for

The widget is drawn by a small JavaScript embed hosted at widget.currency.wiki . Live exchange rates (and, for the chart styles, historical data) are read from api.currency.wiki , and currency flag images are loaded from cdn.currency.wiki . The plugin does not bundle the widget, the rates, or the flag images; it builds an embed URL and loads them from the service. This is what keeps the plugin small and lets exchange rates stay current without a plugin update.

What data is sent, and when

• On every page view where the widget is displayed , the visitor’s browser loads the widget from https://widget.currency.wiki/v3/ — either the script.js injector or the /v3/embed iframe, depending on the embed method you chose. To show live numbers it then requests current rates, and for chart styles historical data, from https://api.currency.wiki , and flag images from https://cdn.currency.wiki/flags/ . These requests carry the display settings you configured — currency pair, amount, style, theme, accent color, language, and similar display options — as URL parameters. As with any web request, the visitor’s IP address and user agent are visible to the server.
• No personal data is collected, and no cookies are set. Exchange rates and flags are public reference data; nothing about your visitor is sent beyond the ordinary contents of an HTTP request.
• In the WordPress admin , live previews are loaded from https://widget.currency.wiki/v3/embed (flagged preview=1 so they are not counted as a site using the widget) on two screens: the settings dashboard, which shows a live preview and an “All Widget Styles” gallery, and the block editor, which previews the block as you configure it. These send the same display settings listed above; no personal data is sent from the admin.
