Terminbuchung & Kontakt-Button – Delta Booking Button

Delta Booking Button macht aus deiner WordPress-Seite ein self-hosted Online-Terminbuchungs-System mit einem schwebenden Buchungs- und Kontakt-Button. Gebaut für lokale Dienstleister – Friseure, Coaches, Praxen, Kanzleien und Agenturen –, die Termine online annehmen wollen, ohne die Daten ihrer Kunden an einen externen Anbieter zu geben. Buchung, Erinnerungen und Kalender laufen komplett auf deinem Server: kein externer Buchungsdienst, kein CDN, kein IP-Leak.

Appointment Booking

• Event Types — unlimited appointment types with custom duration, buffer time, working hours, and custom questions
• Booking Popup — clean calendar with date and time-slot selection, opened from the floating button
• Auto-Reminders — confirmation and 24h reminder email with an ICS calendar file attached, sent via WP-Cron
• Self-Service Reschedule — token-based link, no login required for your client
• External Calendar Sync (optional) — read busy times from an iCal/Google/Outlook feed to block double-bookings
• Timezone Support — UTC storage, visitor-local display, DST-safe

Floating Button & CTA

• Three Button Types — Single Button, Multi-Action FAB, Chat Widget
• 369 Icons — Social, UI, E-Commerce, Brands, Arrows, Navigation (local SVG sprite, no CDN)
• Smart Triggers — Time-based, Scroll Depth, Exit-Intent, Device, User State, URL Conditions
• Action Types — booking, WhatsApp, Telegram, phone, SMS, email, links and webhooks

Conversion Tracking

• Behavioral Tracking — Impressions, Clicks, Hover-Intent, Rage-Click Detection, Conversion Events
• Funnel Analytics — Impression > Hover > Click > Conversion with drop-off rates
• UTM Tracking — source/medium/campaign/content/term per click

Privacy & Self-Hosting (GDPR)

External Services

This plugin does not contact any external server for updates, telemetry, license verification, or analytics, and bundles all assets (CSS, JS, SVG icons) locally (no CDN). It connects to an external service only in the one optional, admin-controlled case described below.

External calendar (iCal) sync — optional, off by default

If — and only if — you enter an external calendar feed URL (an iCal/ICS link such as a Google Calendar, Microsoft Outlook, or Apple iCloud secret iCal address) for an appointment type, the plugin fetches that URL from your server to read busy times, so slots already taken in that calendar are blocked against double-booking.

• What is sent and when: a standard HTTP GET request to the exact URL you configured, performed while the booking calendar computes available slots (the result is cached for about 15 minutes). No data about your site, visitors, or bookings is transmitted — the plugin only reads the calendar. If no iCal URL is configured, no request is ever made.
• Where: the request goes only to the calendar provider whose URL you entered. Please review that provider’s terms and privacy policy, for example Google Calendar (https://policies.google.com/terms, https://policies.google.com/privacy), Microsoft (https://www.microsoft.com/servicesagreement, https://privacy.microsoft.com/privacystatement) or Apple iCloud (https://www.apple.com/legal/internet-services/icloud/, https://www.apple.com/legal/privacy/).

Email and messenger links (no third-party servers)

• Email (booking confirmations and reminders) is sent with WordPress’s built-in wp_mail() and your own server configuration. No external email API is used. ICS calendar files are generated locally and attached.
• WhatsApp, Telegram and other messenger buttons generate standard https://wa.me/ and https://t.me/ links that open in the visitor’s own browser. The plugin sends no data to those services server-side.
• If you configure a webhook action (admin-only), the destination URL is entirely under your control; no default webhook endpoint is pre-configured.

Privacy

Delta Booking Button captures anonymized interaction data for button performance analysis. No personal data is stored without explicit user consent. IP addresses are anonymized by default (last octet removed). Cookie consent is automatically respected through common consent plugins.
