Cancelling a membership

You can cancel your Arca membership here on our website. In order to cancel a membership you need to fill out this FORM. Cancelling a membership cannot be done via e-mail or phone. 

Memberships can be terminated at any time with a notice of current calendar month + 1 calendar month, unless otherwise stated upon registration. All offer memberships purchased through Arca’s website have a binding period of at least one calendar month as a paying member. The minimum price is therefore the front page offer price + DKK 499 (DKK 429 for students).

If you have won or received 2 months of training, you can choose your membership after the offer has ended, and train all the way down to DKK 429 / month. If you do nothing, you will automatically transfer to our all zones membership for DKK 499 / month. They are automatically drawn the first of each month via DIBS.

If you do not wish to continue your membership after the first 2 months of training, you must actively terminate your membership no later than the 25th the month after your offer starts, via our termination form at arca.dk/udmeldelse. Please note that the notice period thereafter is current month + 1 month.

You are of course welcome to participate on WODs during the notice period. If a membership is put on hold the membership will become active during the final month of the notice period. You will receive a confirmation of your resignation, which we recommend that you keep in case of any issues.


Members have to use their QR code in Arca app to ‘punch in’ in order to attend a workout. This is done by scanning the QR code in the QR scanner located in the gym. This must be done no later than 5 minutes before the beginning of the scheduled workout. If members forget to ‘punch in’ or fail to attend a scheduled workout they will be charged fee of DKK 49,-. You also have to ‘punch in’ for Open Gym. 

You also have the option to signin by using your membership number and your code. Go to the reception screen and type in your info.

Please note that if you forget to ‘punch in’ you will lose your spot on the workout to another member who is on the waiting list. If there is no one on the waiting list you can still attend the workout, but the computer will record you as ‘not having attended’ and you will be charged DKK 49,-. We do not give refunds regarding being late for a workout or missing a scheduled workout.
