You can register with Calenso free of charge and without giving your credit card details. You will use all the functions from the start - Calenso will not impose any restrictions.
See the Calenso prices page to see all the current conditions.
When you reach the test maximum, your widget will be automatically deactivated on all channels. Don't worry, you will be alerted early enough if you get closer to the limit. This will give you enough time to change your subscription to flat rate so that your online appointments will continue to flow.
If your booking widget is deactivated, you will not lose your dates and appointments. Upgrade to the flatrate subscription and all widgets will be unlocked again.
You can find more information about the free subscription here: prices.
