A note on Shopify
Shopify acts as an independent controller in respect of the merchant store data it holds, not as a sub-processor of Cost+. Cost+ receives order data from, and returns Shopify-created order data to, Shopify under Shopify's own data-protection terms with the merchant. See Section 8.3 of our Data Processing Agreement.
