Customers request an available time, and authorized staff approve or reject each request manually. #### Adapt booking with free add-ons Circumflex Booking is the shared foundation. Its built-in setup is designed for appointments, treatments and consultations. Separately installed add-ons specialize it for another purpose. Core remains required, and one booking setup is active on each WordPress site. * [Circumflex Booking Airspace](https://wordpress.org/plugins/circumflex-booking-airspace/) reserves flight-training areas, schedules quiet periods and spreads activity. * [Circumflex Booking Meeting Rooms](https://wordpress.org/plugins/circumflex-booking-meeting-rooms/) helps people find and reserve rooms by location, capacity, facilities and exact start and end time. * Circumflex Booking Events (coming soon) adds event pages, individual and group registrations, capacity limits, QR admission passes and staff check-in. Automatic confirmation, email reminders and ticket recovery are included without Pro. Need another kind of booking? [Tell us how it should work](https://twd.wordpress.org/plugins/circumflex-booking/support@circumflex.no?output_format=md). #### Customer booking * Let customers choose one or several services as configured. * Present related choices in optional expandable groups with one shared description and either one or several allowed choices, while ungrouped services remain direct choices. * Show a practitioner choice or “first available” when several practitioners qualify. Hide the choice when only one qualifies. * Present available dates and start times in accessible calendar and list views. * Show the chosen treatment, practitioner, date, and time together with contact details on one final step, with direct actions to change a choice. * Collect name, email address, phone number, and an optional practical comment. * Reserve a requested time while the booking is pending, preventing another customer from taking it. * Send customer and staff notifications for booking events and reminders. * Give confirmed customers a private link to view the booking, request another time, or cancel within the configured deadline. #### Administration * Choose appointments or an add-on setup without changing existing data. * Configure services, expandable groups, choice rules, durations, buffers, prices, deadlines, display order and opening-hour limits. * Configure practitioners, service assignments and weekly hours. * Close dates, add extra hours or block time for one or all practitioners. * Review bookings and availability in day, week and month calendars. * Optionally let linked practitioners decide only requests assigned to them. * Configure and preview email identity and templates. * Use WordPress privacy tools, retention, diagnostics, configuration transfer, and the selected privacy policy. #### Add the booking form anywhere Circumflex Booking does not create or reserve a booking URL. Add its block, the [ circumflex_booking] shortcode, or optional Elementor widget. Publish it and share that page’s URL with customers. Elementor, WooCommerce, and customer accounts are not required. All included functionality is available without payment or a license key. Payments and recurring bookings are outside scope. Email uses `wp_mail()`; a separate SMTP plugin is recommended. #### Optional Pro add-on The free plugin works on its own with account-free booking, email verification, manual approval, email confirmations and reminders, and WordPress.org updates. Circumflex Booking Pro is an optional add-on for appointment, room and training- area booking. Events has its own registration flow: automatic confirmation, email reminders, staff access and ticket recovery are included without Pro. Pro can add: * Optional sign-in and access rules through Microsoft, Google or another provider. * Automatic approval and completion for selected booking types. * SMS confirmations and reminders in addition to email. Sendberry is supported today and requires its own subscription; ask about other providers. * Telegram or browser notifications for responsible staff. * Follow-up, feedback requests and anonymous booking-process insight. * Email support and official Pro updates with an active subscription. [Compare Free and Pro](https://circumflex.no/en/circumflex-booking/pro/#cfx-pro-compare-title). Coming soon in Pro: Stripe payments for events, not available yet. Free event registration remains included in Events. Booking and diagnostics stay on the site. Optional Cloudflare Turnstile is disabled by default and disclosed below. ### Privacy and External Services The site’s database stores customer contact details, optional practical comment, services, practitioner, appointment time, and customer-notice snapshot. Internal notes are visible only to authorized roles. By default, personal data is anonymized 365 days after a terminal status; the period is configurable. Contact details, free text, customer tokens, and identifying notification and audit data are removed. WordPress privacy export and erasure are supported. Erasing an active booking keeps its reserved time. Authorized administrators can generate local diagnostics that omit personal data, free text, tokens, secrets, IP addresses, and site URLs. Nothing is sent to Circumflex AS. #### Cloudflare Turnstile [Cloudflare Turnstile](https://developers.cloudflare.com/turnstile/) is an optional anti-spam service. It is disabled by default and requires Cloudflare keys plus explicit administrator activation. When enabled, the browser loads `https://challenges.cloudflare.com`. Cloudflare processes signals including IP address, TLS fingerprint, User-Agent, site key, and origin. WordPress sends the secret and response token to Siteverify but does not explicitly add the visitor IP. Bookings fail closed if verification cannot finish. Review Cloudflare’s [Turnstile Privacy Addendum](https://www.cloudflare.com/turnstile-privacy-policy/), [Privacy Policy](https://www.cloudflare.com/privacypolicy/), and [Terms](https://www.cloudflare.com/policies/terms/) before enabling the service. The site owner must reflect this processing in the site’s privacy information. ### Source Code Source and build instructions are in the [public Forgejo repository](https://git.etter.no/gvar/circumflex-booking). ### Support Use the Support tab for help.

Install and activate Circumflex Booking. 2. Add at least one service under Circumflex Booking > Services. 3. Add a practitioner, assign services, and configure recurring hours under Circumflex Booking > Practitioners and Circumflex Booking > Availability. 4. Review deadlines, notices, retention, recipients, and email templates under Circumflex Booking > Settings. 5. Select the site’s privacy policy under Settings > Privacy. 6. Create or edit a normal WordPress page, add the block, shortcode, or Elementor widget, publish it, and share its URL. 7. Check Tools > Booking status, then make and process a test booking before opening the page to customers. The tested and supported database baseline is MySQL 8.0 or MariaDB 10.11 and newer. Older versions may work, but they are not tested or supported. Use HTTPS and configure the site’s mail or SMTP setup before accepting real bookings. The database version alone does not deactivate the plugin. ## FAQ ### Does Circumflex Booking create a booking URL? No. Add the block, `[circumflex_booking]` shortcode, or Elementor widget to a normal page you create. Publish it and use that page’s URL. All three use the same booking flow and settings. ### Can analytics measure a successfully submitted booking? Yes. The receipt stays visible and the URL gains `booking-received=1`. For exact GA4 measurement, trigger Google Tag Manager on the Custom Event circumflex_booking_received and send `generate_lead`. It fires once per accepted response and contains no booking or customer data. The plugin does not load analytics; site owners configure analytics and consent. ### Are notification emails sent immediately? An asynchronous worker starts as soon as a message is queued. WordPress cron remains as fallback and for retries. Inbox delivery depends on the site’s wp_mail() or SMTP setup. ### Can customers change or cancel an appointment? Confirmed customers can receive a private link to request a new time or cancel before the deadline. Treat the link as a secret access key. ### Can practitioners approve assigned requests? Yes, when enabled. An active practitioner needs a notification email and linked Practitioner account. Access is limited to their own requests; managers retain access to all requests. ### Should customers enter health information in the comment field? Configure the warning beside the optional comment to tell customers not to submit health or other sensitive data that is not needed for scheduling. ### What happens when the plugin is deactivated or removed? Deactivation and normal uninstall preserve data. Permanent deletion requires an authorized administrator to enable and confirm the uninstall deletion option. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Circumflex Booking” is open source software.
