As we operate small group classes, it is important to cancel your class if you cannot attend it anymore to allow other clients to step in, even if you hold an unlimited ‘All You Can Boost’ pass.

We thank you to cancel your class at least 3 hours prior to its start, by logging into your Booster account on the website or through the mobile app. Go to your profile and your scheduled activities, and click on the class you wish to cancel.

If you cancel less than 3 hours before the start of the class (‘late cancel’), or if you do not attend your class (‘no show’), you will unfortunately lose your class credit or be automatically charged CHF25 if you are using an unlimited ‘All You Can Boost’ pass, unless you have a ‘late cancellation joker’ available (see infra).

If you are not 100% sure you can make it to a class, do not take the risk losing it, you always have the option to book it a few minutes before it starts.

Booster Late Cancellation Joker

We really do not like to charge clients for unattended classes and sometimes you simply have really no other choice than to cancel your class less then 3 hours before it starts.

This is why we offer one ‘late cancellation joker’ per year, ie. one chance per calendar year to get back your class credit. For clients using a ‘All You Can Boost’ unlimited pass, the CHF25 automated charge on your credit card will be cancelled or reimbursed.

We will send you an email to confirm you when we have used one of your joker. This process is not automated, and it takes us a few days to process late cancellations jokers. If you do not hear from us one week after your late cancellation, feel free to send us an email at

Please note that the jokers cannot be used for ‘No shows’, ie. when you do not show up to a class and that unused jokers do not cumulate year on year.
