There are no charges during June, July, and August, when training sessions are not held. Regular billing resumes in September. If you join during the summer break, your first payment will be collected on September 1.
The membership price may be changed with advance notice. The new price will apply to all active members from the date stated in the notice.
What the membership includes
- access to three karate e-book resources;
- the right to participate in training sessions in Belgrade from September 1 through May 30;
- a reserved place in the group while the membership remains active.
Joining and managing your membership
When joining, you provide your first and last name, email address, telephone number, billing address, and details of any additional family members.
After a successful payment, you will receive an email confirming that your membership is active, an invoice, and links to the e-book resources. After each monthly charge, you will receive an email notification and invoice.
Use the “My membership” link to sign in by email and access the Stripe Customer Portal, where you can update your card, download invoices, or cancel your subscription.
Payment is not available to customers from the United States.
Club rules
- The training hall is limited to 20 people. Membership remains payable when a member is absent because of illness, travel, or another reason. An active membership reserves your place in the group.
- Do not attend training if you are ill, feel unwell, or have symptoms that could put other members at risk.
- Each member must complete a sports medical examination once a year and send the report directly to the instructor, not to the group.
