Subscriptions are a recurring fee that will automatically be billed every month through PayPal until you cancel.
You may cancel at any point. Your account will remain active until your billed period has come to pass even if you cancel before that date. For example, if you sign up for an account and are billed for 1 month and your account is to re-bill on the 1st of the month, and you cancel before that date, you will have access to your data until the 1st at which time the data will be shut off and you will no longer be billed.
