How do I cancel my Saint Patrick's Day subscription?

The recurring charges are managed directly by Shopify so uninstalling the app will automatically cancel your subscription to the app and prevent any future charges.

Anyway, it's good to disable the app first to ensure that all traces of our code are also removed from your store templates. You can do that from the app preferences page:

Then go to your Shopify admin, section ' Apps' and click on the waste bin icon on the right side of the app listing:

Finally, please note that all payments are managed directly by Shopify. It is Shopify, not us, who charges you, and then transfers our part to us. 

For that reason, we cannot create or refund charges or control the billing cycle. We don't have access to your payment data either.  

You can contact Shopify support for any question related to the app charges.
