<p>WhenPilot is a lightweight appointment booking plugin for small businesses — salons, clinics, consultants, tutors. Everything stays on your own site; there is no third-party booking service.</p>
<p><strong>Features</strong></p>
<ul>
<li>Define <strong>services</strong> (name, duration, optional price, description).</li>
<li>Set your <strong>weekly opening hours</strong> in a simple text format (e.g. <code>Mo-Fr 09:00-17:00</code>).</li>
<li>Visitors book with the <code>[whenpilot]</code> shortcode: pick a service, a date, and a <strong>free time slot</strong> computed from your hours and existing bookings.</li>
<li><strong>Double-booking prevention</strong>: slots are re-validated on the server before saving, with a configurable capacity (e.g. number of staff).</li>
<li><strong>Admin inbox</strong>: see upcoming/pending/confirmed/cancelled bookings, confirm, cancel or delete.</li>
<li><strong>Email confirmations</strong> to the customer and a notification to you, plus emails when you confirm or cancel.</li>
<li>Configurable lead time, how far ahead people can book, currency label and an optional auto-confirm.</li>
<li>Uses your site’s timezone. Works with any theme.</li>
</ul>
<p><strong>Usage:</strong> create a page, add the shortcode <code>[whenpilot]</code>, and publish.</p>
<p>All features described above are fully functional in this plugin — no time limits, no usage caps, no locked options. WhenPilot does not connect to any external service. A separately distributed companion plugin offers additional features (multiple staff/resources with custom fields, automatic email reminders) but is not required for the plugin to work.</p>
<h3>Privacy</h3>
<p>Bookings (name, email, optional phone and notes) are stored in your own database and emailed to you and the customer. No data is sent to any third party.</p>

<h4>Booking flow</h4>
<ol>

<li>Visitor fills in name, email, phone (optional), notes (optional), and any custom fields.</li>

</ol>
<h3>Privacy</h3>
<p>This plugin stores personal data submitted by visitors when they book an appointment: name, email address, phone number (optional), any custom field values you have configured, IP address (transiently, for rate limiting), and the booking details themselves.</p>
<p>Emails are sent through your site’s mailer (<code>wp_mail()</code>) to the visitor’s email address and the administrator email configured in Settings. No data is sent to external services by default.</p>
<p>If the <strong>Webhook</strong> integration is enabled in Settings, booking events are POSTed to the URL you configure. Site administrators are responsible for ensuring that the destination complies with their privacy policy and applicable data protection law.</p>
<p>Booking records are retained until manually deleted or until the plugin is uninstalled via the Plugins screen, which drops all plugin tables and options.</p>
<h3>Development</h3>
<p>Source code: https://github.com/ajayrajbanshi/nivaj-appointment-hub</p>
<p>The compiled JavaScript and CSS files in <code>assets/build/</code> are generated from the human-readable source under <code>src/</code> (React/JSX components and SCSS) using <code>@wordpress/scripts</code> (webpack).</p>
<p>To build from source:</p>
<pre><code>npm install
npm run build
</code></pre>
<p>This produces <code>assets/build/admin-app.{js,css}</code>, <code>assets/build/booking-widget.{js,css}</code>, and <code>assets/build/block-editor.js</code> from <code>src/admin-app/</code>, <code>src/booking-widget/</code>, and <code>src/block-editor/</code> respectively. To produce the wordpress.org distribution zip, run <code>npm run package</code>.</p>
<p>No third-party libraries are bundled outside of <code>@wordpress/*</code> packages provided by WordPress core (<code>wp-element</code>, <code>wp-components</code>, <code>wp-i18n</code>, <code>wp-api-fetch</code>, <code>wp-blocks</code>, <code>wp-block-editor</code>).</p>
