Cancel Subscription
Billing for the app is handled by Shopify. When the app is uninstalled from your shop, Shopify automatically cancels your subscription, and you will no longer be charged for the app.
If you uninstalled the app in the middle of a billing cycle, you will still see a charge for the last billing period. If you have any questions or issues with your billing, create a support ticket, and we will take care of it for you.
