<h3>External services</h3>
<p>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.</p>
<p>The plugin communicates with the WebCallHub service at <code>app.webcallhub.com</code> in two ways:</p>
<p><strong>1. Loading the call widget script (<code>app.webcallhub.com/api/widget.js</code>)</strong></p>
<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>
<p><strong>2. Domain handshake on Site Key save (<code>app.webcallhub.com/api/widget/wp-handshake</code>)</strong></p>
<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>
<p>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.</p>

WebCallHub — Click-to-Call Widget

Add a click-to-call button to your WordPress site. Let visitors call your support team directly from their browser — no phone, no app, no downloads.

Royal Bengal AI

<p>This is the official Zavora 360 plugin, built and maintained by Royal Bengal AI — the team behind the Zavora 360 Virtual Receptionist platform at <a href="https://zavora360.royalbengal.ai" rel="nofollow ugc">zavora360.royalbengal.ai</a>.</p>
<p>Zavora 360 is a Virtual Receptionist that answers your website visitors’ questions in real time using advanced voice technology. This plugin adds a floating “Talk to Us” button to your WordPress site — visitors click it, a small popup opens, and they’re talking to your custom-trained Virtual Receptionist within seconds. As of v1.2.0, you can also add a floating Chat button so visitors who prefer text get the same Virtual Receptionist in a chat window.</p>
<p>The agent speaks the visitor’s language (English, Hindi, Bengali, Spanish, Arabic, French, and more), is trained on your own knowledge base, and is available 24/7. No phone calls needed — it all runs in the browser.</p>
<h4>What this plugin does</h4>
<ul>
<li>Adds a floating “Talk to Us” voice button to every page of your site (configurable)</li>
<li>Adds a floating Chat button alongside the voice button (v1.2.0+, independent toggle)</li>
<li>Lets you place either surface mid-content with the <code>[zavora_360]</code> (voice) and <code>[zavora_360_chat]</code> (chat) shortcodes</li>
<li>Customize each button’s color, label, position, and size independently</li>
<li>Hide either button on specific pages, or only show on specific pages</li>
<li>Auto-detects WooCommerce and lets you hide both buttons on cart/checkout</li>
</ul>
<h4>Requires a Zavora 360 account</h4>
<p>This plugin is the WordPress connector for the Zavora 360 platform. You’ll need an account at <a href="https://zavora360.royalbengal.ai" rel="nofollow ugc">zavora360.royalbengal.ai</a> — the Free plan includes 10 minutes per month at no cost and no credit card.</p>
<h4>Privacy and data</h4>
<p>This plugin doesn’t collect or transmit any visitor data on its own. When a visitor clicks the button, a popup window opens pointing to the Zavora 360 platform (zavora360.royalbengal.ai). All voice processing happens there, under Zavora 360’s <a href="https://zavora360.royalbengal.ai/privacy" rel="nofollow ugc">privacy policy</a>.</p>
<p>The plugin stores your API key and display preferences in your WordPress database (wp_options table). No visitor data is stored by the plugin.</p>
<h3>External services</h3>
<p>This plugin connects to the Zavora 360 platform, an external service provided by Royal Bengal AI. The connection is required for the plugin to function — without a valid Zavora 360 account and API key, the button will not load. The plugin does not contact any other third-party services.</p>
<p><strong>What the plugin sends to Zavora 360:</strong></p>
<ul>
<li>When you save an API key on the settings page, the plugin makes a single GET request to <code>https://zavora360.royalbengal.ai/api/external/widget-config</code> with the API key in an <code>X-API-Key</code> header. This validates the key and fetches your account’s button configuration (label, color, position, size, plan, minute balance). The request also includes a <code>User-Agent</code> header in the form <code>Zavora360-WP/{version}; {your-site-url}/</code> so the platform’s logs can distinguish plugin traffic from other API consumers.</li>
<li>When a visitor clicks the Talk-to-Us button, a popup window opens at <code>https://zavora360.royalbengal.ai/call?company={your-company-slug}</code>. The browser handles the voice conversation directly with the platform from that point on — the plugin and your WordPress server are not involved in the conversation itself.</li>
</ul>
<p><strong>What the plugin does NOT send:</strong></p>
<ul>
<li>No visitor data (name, email, IP, behavior) is sent to Zavora 360 by the plugin.</li>
<li>No post content, page content, or WordPress database content is sent.</li>
<li>No data about your other WordPress plugins or theme is sent.</li>
<li>The plugin makes no analytics, tracking, or telemetry calls of any kind.</li>
</ul>
<p><strong>When the calls happen:</strong></p>
<ul>
<li>The <code>widget-config</code> API call runs once when you save the API key on the settings page, and again whenever you click “Refresh config” on the same page. It does not run on visitor page loads — the configuration is cached in WordPress options.</li>
<li>The popup-window URL is constructed in the browser when the visitor clicks the button. No server-side call from your WordPress site is made at click time.</li>
</ul>
<p><strong>Terms and privacy:</strong></p>
<ul>
<li>Zavora 360 terms of service: <a href="https://zavora360.royalbengal.ai/terms" rel="nofollow ugc">https://zavora360.royalbengal.ai/terms</a></li>
<li>Zavora 360 privacy policy: <a href="https://zavora360.royalbengal.ai/privacy" rel="nofollow ugc">https://zavora360.royalbengal.ai/privacy</a></li>
</ul>
<p>By using this plugin, you agree to the Zavora 360 terms of service. If you are subject to GDPR or similar privacy regulations, you should mention Virtual Receptionist usage in your own site’s privacy policy.</p>
