Per our Terms and Conditions, subscriptions must be canceled with a notice period of one (1) month to the end of the agreed contractual period. Subscription charges for renewals are non-refundable and the deletion of an account has no effect on eventual payment obligations.
Furthermore, please note that canceling your subscription / account on the same day of signing up will not initiate a refund. Requests to revoke your subscription must be sent to customer support by using the 'Contact Form' in your account.
