You can cancel and unenroll from your Nanodegree program within the first 7 days from your first month’s subscription purchase date in order to be eligible for a full refund, unless you have graduated from the Nanodegree program within this timeframe. Only one refund may be granted per Student per Nanodegree program. If you cancel your subscription, and subsequently re-enroll for an Online Course, you will not be entitled to an additional 7-day refund period.
You may cancel your subscription at any time after this 7-day refund period and you will not be charged again after the billing period in which you cancelled. You will remain actively enrolled in the program until the end of this billing period.
After the first month, you may elect to either 'cancel' your monthly auto-renew subscription, or if you are in a manual monthly subscription, you can elect not to renew for subsequent months.
Following the 7-day refund period, there will be no further refunds, including no partial refunds for termination during the fixed, multi-month term, or during any monthly automatic subscription periods following the initial fixed, multi-month term.
Refund Policy for Citizens and Residents of European Union. Citizens and residents of the European Union are entitled to a full refund during the first Fourteen (14) days following when the subscription begins. The 14-day refund is only available during the first month, and all other refund and cancellation terms also apply.
