Terms of service
Refund policy:
If you wish to claim a refund, you can do so within 30 days following your purchase of NordVPN service. We want you to be fully satisfied with our services. However, we will troubleshoot an issue you experience first. There are several nuances to a VPN service configuration and we solve 99% of issues encountered. NordVPN reserves the right to suspend, terminate, or refuse service to anyone at any time for any reason. No refunds will be considered for accounts deleted for violation of our Terms of Service.
Subscriptions purchased via the iTunes/App Store are subject to iTunes/App Store refund policies. This means we cannot grant refunds if you purchased an app directly through the iTunes/App Store – you will have to contact the iTunes/App Store support for that. Payments made using pre-paid cards or gift cards will not be refunded. For payments made in Bitcoin, the equivalent amount in US Dollar will be refunded in Bitcoin, regardless of exchange rate fluctuations.
