<h3>External services</h3>
This plugin relies on the WebCallHub service to provide browser-to-browser click-to-call functionality. WebCallHub is operated by HSG IT USA LLC (Austin, TX, USA) and HSG IT Services Oy (Finland), the same company that distributes this plugin.
The plugin communicates with the WebCallHub service at <code>app.webcallhub.com</code> in two ways:
1. Loading the call widget script (<code>app.webcallhub.com/api/widget.js</code>)
<ul>
<li>What it is: The JavaScript file that renders the click-to-call button and handles the WebRTC voice call.</li>
<li>When it is sent: On every front-end page view where the widget is enabled and a Site Key is configured.</li>
<li>What data is sent: Your configured Site Key (passed as the <code>siteId</code> query parameter) plus the standard HTTP request metadata the visitor’s browser sends to any external script host (IP address, user agent, referring page). No visitor form data is submitted by the plugin itself.</li>
<li>Why: The widget UI and the call session must be served by the WebCallHub service in order to establish a voice call.</li>
</ul>
2. Domain handshake on Site Key save (<code>app.webcallhub.com/api/widget/wp-handshake</code>)
<ul>
<li>What it is: A one-time <code>POST</code> request sent from your WordPress server to the WebCallHub backend when you save a new Site Key in the plugin settings, or when the plugin is re-activated with a Site Key already configured.</li>
<li>What data is sent: Your Site Key, your WordPress site URL (<code>home_url()</code>), and the plugin version. No visitor data is sent.</li>
<li>Why: WebCallHub uses this handshake to verify that the WordPress install at the claimed domain is actually running the plugin, so it can auto-mark your site as domain-verified in the WebCallHub dashboard.</li>
</ul>
Any voice call audio, visitor name, or transcript data is exchanged directly between the visitor’s browser and the WebCallHub service (not via this plugin’s PHP code) and is governed by WebCallHub’s own privacy policy.
