At Cratejoy, we want to make sure that both your data and your customer's data remains safe and secure from prying eyes. In order to help protect this data, we employ a security protocol known as SSL that goes into effect when your customers browser certain parts of your store (For more information on SSL, check out this help article). The following pages require SSL: your subscribe flow, the checkout page, pages that add items to the cart, and all customer pages (like the customer "My Account" page).
By default, the Cratejoy platform provides the SSL certificate that makes your store secure. This means that, even if you have a custom domain specified, the ".cratejoy.com" domain will be used when customers access parts of your store that require SSL.
By doing this automatically you do not have to setup a complicated configuration to make sure your subscribers feel secure when they checkout. Cratejoy handles it for you.
