What happens when I switch between paid plans in the middle of a billing period?
When you upgrade to a higher plan, you can exploit the benefits of the higher plan immediately and your credit card is charged with the differences between the old and the new plan for the remaining days in the current billing period.
When you downgrade to a lower plan, you are credited with the differences between the old and the new plan prorated for the remaining period. You can check your credit on the Plan and Billing settings. If you have more credit than the next period's fee, your credit card won't be charged and you won't receive a receipt.Please note that we can't refund credits, you need to use it up in our service.
