Students are required to add a payment method before booking a class. At this time, we can only accept credit card payments (Visa or Mastercard). Don't worry, we don't store or save your credit card information – we don't have access to it. Plus, any information you provide is kept private and secure thanks to a security encryption provided by Stripe. If you have any questions or concerns about payment security, check out Stripe's documentation at https://stripe.com/docs/security/stripe.
