<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>
