<h4>External Service Disclosure</h4>
This plugin relies on the MetalflowAPI service (metalflowapi.com) to fetch real-time and historical precious metals prices. By using this plugin you agree to MetalflowAPI's terms of service and privacy policy.
What data is sent to MetalflowAPI from your WordPress server:
<ul>
<li>Your API key (passed in the <code>X-API-Key</code> HTTP header) — used for authentication and rate-limit tracking.</li>
<li>Query parameters required to fulfil your shortcode/block (metal symbol, currency, date range, etc.).</li>
<li>The IP address of your WordPress server (standard for any outgoing HTTP request).</li>
</ul>
What is NOT sent:
<ul>
<li>No personally-identifiable information about your site visitors. The plugin never collects, transmits or stores visitor IPs, cookies or browsing behaviour.</li>
<li>No content of your WordPress posts, comments or user accounts.</li>
</ul>
Cache: all responses are cached locally on your server via WordPress transients (default 5 minutes, configurable) so the same query does not hit MetalflowAPI repeatedly.
Before you add an API key: the plugin shows built-in static sample data and makes no request to MetalflowAPI. The service is only contacted once a valid API key is saved.
Service endpoints used:
