Optional — Google Maps (not affiliated with Google): If the site owner enables embedded maps under Settings → Partner Portal, listing pages can show a button for visitors to opt in before loading an iframe from https://maps.google.com/. Until the visitor clicks that button, no request is sent to Google. When loaded, the visitor’s IP address and map coordinates may be processed by Google. Terms: https://www.google.com/intl/en/policies/terms/ — Privacy: https://policies.google.com/privacy Optional: Listing video embeds use WordPress wp_oembed_get() for URLs the site owner adds (e.g. YouTube). WooCommerce integration loads only when WooCommerce is active. Demo content uses placeholder images bundled in assets/demo/ (no remote downloads). Privacy Booking forms collect customer name, email, phone, and booking details stored in your WordPress database. Configure your site privacy policy for GDPR compliance.
