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.
