Kalendar works with your calendar, your meetings and your mailbox
Connect an account once and Kalendar keeps itself in step with it. Nothing to install, nothing to export, nothing to keep in sync by hand.
Calendars
Kalendar reads your calendar before offering a slot, so a private appointment blocks a public one. When a booking is made it writes the entry back.
Google Calendar
Two-way: read for conflicts, written to on every booking.
Microsoft 365 / Outlook
Microsoft 365 and Outlook calendars, handled the same way.
Online meetings
Choose a meeting tool on an appointment type and the link is created when the booking is made — and sent to both of you.
Google Meet
A Google Meet link created automatically for each online appointment.
Zoom
Meetings created on your own Zoom account.
Microsoft Teams
Microsoft Teams meetings, created and shared with the invitee.
Payments
Connect your own merchant account and take the fee or the deposit as the client books. The money goes to you directly.
Viva Wallet
Take card payments through your own Viva Wallet account.
PayPal
Take payments and deposits through your own PayPal account.
Send confirmations, reminders and follow-ups from your own address rather than a generic one.
Gmail
Send from a Gmail address, connected with a single Google sign-in.
Microsoft 365
Send from a Microsoft 365 mailbox, connected the same way.
SMTP
Any other mailbox — Outlook, Yahoo, or your own business email over SMTP.
SMS
Connect your own Apifon account and the appointment messages go out as a text as well as an email. Apifon charges you for the messages directly. Paid plans only.
Apifon
Confirmations, reminders and cancellations texted to your clients, under your own sender name.
For developers
Everything the interface does is available over a documented REST API, and any workflow can call a webhook.

Kalendar only ever creates entries in your calendar. It never edits or deletes anything that was already there.
