Nine locations to choose from
Google Meet, Teams, Zoom, Webex, Whereby, your own video URL, phone, in person — or “to be announced”.
Availability
Your week sets the rules.
Set weekly rules (“Mon and Wed, 9–12”) — Klausi fills a year of availability from them. Exceptions like vacation block single days. Try it:
- Weekly rules instead of managing slots by hand
- Exceptions: block a vacation day or open an extra window
- Notice (1–48 h) and booking window (7–90 days)

Emails that think along
Guests get a confirmation with calendar button and cancel link; you get the calendar file (ICS) on top.

Frequent questions
Questions about booking.
How is Klausi different from Calendly or Cal.com?
Klausi is free, GDPR-compliant with EU hosting, has no link limit, and gives you your own /meet address. In exchange there’s no two-way calendar sync — but booking is connected directly to clients, projects, and hours.
What does booking cost?
Nothing. Booking links belong to Klausi’s free core — with no limit on the number of links.
Can I create several event types?
Yes. You create as many booking links as you like — each with its own duration, location, and settings. That’s free too.
How do time zones work?
Your link has a home time zone; guests see and book slots in theirs automatically. Both emails show the matching local time.
Can guests cancel?
Yes. Every confirmation contains a personal cancel link — if the guest cancels, you get an email immediately.
Can I protect booking links?
Yes. Optional password protection (stored encrypted), an expiry date per link, and a switch against double bookings.
Do I lose my calendar sync?
Klausi has no automatic two-way sync. But every booking reaches your calendar via an ICS file and an “add to calendar” button — and the slot is linked to client and project right away.
