The interface, field labels, holiday handling, and email templates are all tuned for Japanese business use. ### Is it Made in Japan? Yes. Probono Booking is developed by Japanese developers who understand the conventions and expectations of Japanese web booking systems. ### Can I use it with other booking plugins? Probono Booking works as a standalone plugin and does not depend on other booking plugins. Running multiple booking plugins on the same page may cause CSS or script conflicts, so we recommend using only one booking plugin per site. ### Does it work with any WordPress theme? Yes. The plugin uses scoped CSS and renders inside a containerized form, so it works with most modern WordPress themes without layout issues. ### Is there a monthly fee? No. The plugin is a one-time install. There is no recurring fee. ### Where is the reservation data stored? In a custom database table on your own site. Reservation data is never sent externally. The plugin makes no outbound HTTP requests at all. ### Are Japanese national holidays supported? Yes. Public holidays, substitute holidays (振替休日), and bridge holidays (国民の 休日) are applied automatically to the booking calendar. ### Does this plugin collect user data? No. Probono Booking does not transmit any personal information to external services. Reservation data submitted through the form is stored only in your own WordPress database. The plugin makes no outbound HTTP requests; Japanese national holidays are computed locally. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Probono Booking Basic” is open source software.
