S Label uses Maximum Data Sharing which uses Facebook's Conversions API as well as the Facebook pixel. Data is shared using the customer's web browser and from Shopify's servers, and is sent directly to Facebook's servers. Data sent from server to server can't be blocked by browser-based ad blockers. The Maximum setting shares the customer's personal information to match users on Facebook's network. The information collected using this setting includes your customer's name, location, email address, and phone number, as well as their browsing behavior on S Label.
