Tikk checks every connected calendar before showing a slot. A dentist appointment, a blocked focus hour, a meeting someone else put in your diary. Any of them removes that slot from your booking page. There’s nothing to configure per event and nothing to remember. It’s always on.

4

Choose which calendars count

One account often holds several calendars. Click Manage calendars on a connection to pick which of them block your availability. Only the ones you activate are checked.
The Free plan allows 1 active calendar connection. Pro is unlimited.

Connection states

An expired connection is the one failure mode that can cause a double booking, because Tikk can no longer see that calendar’s events. The dashboard flags it, so reconnect promptly.
If you move from Pro back to Free with several connections, nothing is deleted. Your oldest connection stays active and the rest are paused until you upgrade.

How it works

Once connected, Tikk checks your calendars in real time whenever someone opens your booking page. Any overlap with any event, even by a minute, hides the slot. No manual sync, no polling delay.
Connect your personal calendar too, even if you only take work bookings. Tikk reads the times you’re busy, not what you’re doing. Personal event details stay private, they just stop people booking over your evening.

Bookings on your calendar

When a booking is confirmed, Tikk writes an event with the meeting title, the booker’s name and the meeting link to every connected calendar, not just one. You don’t have to copy anything across and whichever calendar you happen to be looking at shows the booking. Reschedule or cancel the booking in Tikk and that calendar event is updated or removed to match. See Manage bookings.
