Google Calendar Scheduling Software Built for Privacy and Simplicity
Turn your Google Calendar into a powerful, automated booking engine. Kalendarius connects seamlessly with Google Workspace and personal Google accounts to offer frictionless appointment scheduling without double bookings.
Kalendarius turns Google Workspace and personal Google calendars into an automated booking system with bidirectional synchronization and conflict prevention. Core Kalendarius booking data is hosted in the EU; data exchanged with Google remains subject to Google Workspace terms and the customer's configuration.
Real-Time Bi-Directional Google Calendar Sync
Kalendarius syncs with your Google Calendar in real time. When an event is added or moved on your Google Calendar, your Kalendarius availability updates instantly to prevent scheduling conflicts.
When an invitee books a time through your Kalendarius link, the event is immediately created on your Google Calendar with complete meeting details, attendee info, and automatic Google Meet or custom video links.
Multiple Calendars and Conflict Prevention
Manage both work and personal calendars? Kalendarius allows you to check availability across multiple Google calendars simultaneously, ensuring personal appointments and internal work meetings are always respected when presenting open slots to clients.
Customizable buffer times ensure you always have breathing room between calls, while minimum notice settings prevent last-minute surprise bookings.
European Privacy for Google Workspace Users
European businesses using Google Calendar may prefer an independent scheduling layer with EU-hosted core infrastructure. Kalendarius minimises stored calendar content and keeps its core booking database in the EU, while the Google connection remains a data flow that each customer must assess.
Only calendar busy/free blocks are evaluated to compute booking slots, maintaining the utmost confidentiality for your client and internal schedules.
Fast Setup and Custom Booking Pages
Connect your Google account with OAuth in seconds. Customize your booking page with your logo, meeting durations, custom question fields, and brand colors.
Embed your booking widget directly on your website or share your personalized URL via email signatures and social profiles.
Frequently Asked Questions
Does Kalendarius sync with Google Calendar in real time?
Yes. The synchronization is bidirectional and real-time. When someone books a slot through your Kalendarius link, the event immediately appears in your Google Calendar with video links. If you add or move an event directly in Google Calendar, your Kalendarius booking slots update instantly to prevent double bookings.
Can I check multiple Google calendars for conflicts?
Yes. You can connect and check multiple Google calendars (for instance, a work Google Workspace calendar and a personal Google calendar) so that personal appointments automatically block out work booking slots without revealing personal details.
Does Kalendarius store the contents of my Google Calendar events?
No. Kalendarius only reads free/busy status blocks to compute open booking slots. The private titles, descriptions, and participant details of your existing personal or company meetings are never stored on our servers.
Are Google Meet video links generated automatically?
Yes. You can configure your booking links to automatically generate and attach Google Meet video conference links to both host and invitee calendar invitations upon booking.
