In case you would like to close your account you can cancel your subscriptions and preapprovals by going to your Paypal account directly.

In order to cancel your subscriptions, you will need to go to your account settings, then to subscriptions.  The direct link is:
https://www.paypal.com/myaccount/settings


If you are trying to cancel a pre-approval, you will not find that in your list of subscriptions.  You will need to be logged into Paypal and go directly to:
https://www.paypal.com/us/cgi-bin/webscr?cmd=_ap-manage-preapprovals

That will allow you to control, and more importantly cancel, any preapprovals that you have set up with Paypal.
