Refund policy

PolarDB supports unsubscription and offers partial refunds.

• The refund policy for PolarDB varies based on the billing method:

  Billing method	Refund policy
  Subscription	For subscription PolarDB clusters, you prepay for resources based on the subscription duration, product series, and node specifications. If your business needs change and you no longer require a subscription cluster, request a refund. When you request a refund, the system calculates the amount based on your subscription cluster's configuration. For the unsubscription rules for PolarDB clusters, see Unsubscription rules. After you understand the unsubscription rules, submit an unsubscription request in the PolarDB console. For more information, see Submit an unsubscription request.
  Pay-as-you-go	Pay-as-you-go PolarDB clusters generate bills in real time based on actual usage. Therefore, refunds are not applicable. If you no longer need a pay-as-you-go PolarDB cluster, release it. Before you release the cluster, back up or migrate its data to avoid business disruptions. After the cluster is released, you are no longer charged for it.
  Compute plans and storage plans with defined specifications	You can unsubscribe from purchased compute plans and storage plans with defined specifications. For more information, see Unsubscribe from a compute plan or storage plan with defined specifications.

• Refunds may also be available in scenarios such as switching billing methods or downgrading resources. The details are as follows:

  Scenario	Refund policy
  Switch from subscription to pay-as-you-go	After you switch a subscription cluster to pay-as-you-go, the remaining balance of your subscription payment is refunded to your original payment method. Only the amount you paid is refunded to your original payment method. Used coupons are not refunded. For the formula used to calculate the refund for switching from subscription to pay-as-you-go, see Unsubscription rules.
  Downgrade or delete nodes	For information about the fees for downgrading or deleting nodes, see Refund rules for downgrades.
