You can cancel the SmartHelping Plus Subscription at any time. Simply login to your PayPal account and go to Settings > Payments > Select Automatic Payments > Select Merchant and Cancel.
I only use PayPal to manage the SmartHelping Plus subscription, here is their detailed instructions for canceling a subscription.
The subscription will be active through the end of each billing cycle. So if you paid on April 3rd, cancel on April 15th, you will still have access until May 3rd.
