Premium Add-on Unlock advanced features with Oumma EasyBook Pro: Online payments via Stripe, PayPal, and WooCommerce Google Calendar two-way synchronization Automatic PDF invoices with company logo JSON export and import (full backup & restore) Use Cases Wellness centers & spas Hair salons & barbershops Coaching & consulting Medical & dental clinics Fitness studios & personal trainers Photography studios Freemium Model Oumma EasyBook follows a standard WordPress freemium model: This free version is fully functional for appointment booking: unlimited services, unlimited practitioners, booking calendar, email notifications, availability management, and design customization. Premium features (online payments via Stripe/PayPal/WooCommerce, Google Calendar sync, PDF invoices, export/import) are provided by a separate add-on plugin available at oumma-pro.com. No premium code is bundled in this free plugin. The free plugin provides action and filter hooks (e.g., oumma_easybook_settings_tabs, oumma_easybook_frontend_payment_config) that the premium add-on uses to extend functionality. In the admin settings, premium features are shown as non-interactive visual previews (greyed out at 35% opacity with pointer-events:none and a PRO badge) so administrators can see what features are available with an upgrade. These previews contain no functional code: all inputs are disabled, no data is saved, and no premium logic is executed. They are purely informational HTML. Data Handling All booking data is stored in custom database tables on your own WordPress installation. No data is sent to external servers except as described in the External Services section. On plugin deactivation, all data is preserved. On plugin deletion (uninstall), data is only removed if the administrator has explicitly enabled the “Delete all data on uninstall” option in Settings > Advanced. This is an opt-in safeguard to prevent accidental data loss. When enabled, uninstall removes: all plugin options, transients, custom database tables (services, practitioners, bookings, availability, coupons, waitlist, custom fields, bug reports), the auto-generated booking page, and scheduled cron events.
