The Company nonetheless remains the party to the service agreement and bears responsibility for provision of the Service.
  4. The billing currency is determined by the payment provider based on factors such as the Member’s access region and may differ from the currency shown on the pricing page. The amount charged is in any case shown on the payment screen.
  5. Paid plans are charged in advance according to the billing cycle selected by the Member (monthly or annual).
  6. Where a Member has enrolled in recurring billing, the Company charges the registered payment method automatically at the start of each billing cycle. A Member may cancel recurring billing at any time in the Service settings.
  7. If an automatic payment fails, the Company retries for a limited period. If all retries fail, use of the paid plan is discontinued and the Team reverts to the free plan. The Company notifies the Member by email of the payment failure and the scheduled discontinuation.
