If you paid for your trial, and cancel it during the trial period, you will not be refunded for the unused trial period.

Subscription. You can buy a subscription to the Purchased Content either via App Store or Google Play, or through our website using your credit/debit card, PayPal account or other payment service provided for on our website.
