Policies & Member Guidelines

    • Member Cancellations:
      Please cancel your booking through our website or through the Momence app at least 2 hours in advance if your child will not attend a class or open gym session. This allows us to adjust class sizes and make space for other members.

    • Late Cancellations & No-Shows:
      Cancellations made less than 2 hours before the class or no-shows will result in a forfeited class credit.

    • Make-Up Classes:
      Most memberships allow for make-up classes within the same month. Credits will only be available for make-up classes if they are cancelled in accordance with the policies listed above. Please use our website or the Momence app to book your lessons. 

    • Weather / Facility Closures:
      If Ark Ninja must close due to weather, safety concerns, or emergencies, classes will be rescheduled and credited in full.

    Ark Ninja Class Cancellations: At Ark Ninja, classes with no booked athletes at least 2 hours before start time will be canceled. Please make sure to book your classes early so we know who to expect and can staff accordingly.

  • Arriving 5+ minutes late may result in your child missing the warm-up or part of the class instruction. For safety reasons, coaches may not allow entry if arrival is more than 10 minutes late, and the class will be counted as attended and will not be refunded.

    • Membership Types: Ark Ninja offers 4, 8, and 12-Class-per-month packages, as well as 4, 8, and 12 Class Packages that do not expire for 1 year. Per-Month Memberships renew automatically unless canceled at least 48 Hours in advance.

    • Billing: Membership payments are processed monthly on the 1st of the month. Please ensure your payment method is up to date. If payment fails, our system will attempt to process it again on the 3rd and 5th of the month. If no payment is processed, your membership will be cancelled, and all credits will be lost. 

      • You can update your billing information on the momence portal on our website, or through the momence app.

    • Membership Holds / Freeze: Memberships can be placed on hold for medical reasons or extended vacations with at least 48 Hours' notice. You may only freeze your membership for 2 months within a given calendar year. ($10/month)

    • Refunds: Refunds are not offered for missed classes, except in extenuating circumstances or in the event of Ark Ninja closures.

    No-Show Policy: If a client books a class (including recurring bookings) and does not attend without canceling, they will lose the class credit and be charged a $15 no-show fee.

  • 1. Safety First

    Safety is our #1 priority. Always follow instructions from coaches and staff.
    Only Ark Ninja staff may move mats, pads, blocks, or adjust any obstacle.
    One athlete on an obstacle at a time — no exceptions.

    2. Proper Training Attire

    Closed-toe athletic shoes are required at all times.
    Shirts must be worn, and no jewelry is allowed (it can catch on equipment and cause injury).

    3. Stay Off the Mats When Crossing the Gym

    Do not run across the mats.
    Use the carpeted walkways until you know which lanes and obstacles are in use.

    4. Truss & Support Structures Are Not Obstacles

    Do not climb on the truss, rigging, or any supporting structures. 

    5. Respect & Behavior

    Speak kindly and encourage others — we are a community built on positivity.
    Respect fellow ninjas and staff at all times.
     Bullying, disrespect, or inappropriate language will not be tolerated.

    6. Parent Supervision Requirement

    Parents must remain on-site for children under 5.

    7. No Sharp Objects

    Empty your pockets before training.
    No keys, toys, rocks, or any sharp objects on the mats—ever.

    8. No Food or Drinks in the Gym Area

    All food, drinks, candy, and gum must stay in the lobby or mezzanine.
    Only water bottles are allowed on the gym floor.

    9. Obstacle Adjustments Are for Coaches Only

    Athletes may not move blocks, pads, or adjust obstacles. Ask a coach if something needs changing.

    10. Respect the Gym

    Take care of the equipment, be aware of your surroundings, clean up after yourself, and help us keep Ark Ninja a world-class training space.
