Subscriptions
You can add a subscription as a purchase option to sell products on a recurring basis. Customers can choose to pay an agreed price for your product in a scheduled frequency, such as monthly, weekly, or daily.
If you're using the free first-party Shopify Subscriptions app or a third-party subscription app from the Shopify App Store installed in your Shopify admin, then you can manage your subscription products in the Shopify admin.
Customer payment information is stored securely by Shopify. You can't access your customers' full credit card information after it has been entered.
