Amplius Customer Fields is a versatile app designed to enhance user registration by allowing you to record and store additional customer information. By utilizing customer metafields based on your shop's metafield definitions, the app lets you gather data points such as birthdays, weight, height, and favorite colors, among others. These stored metafields can be seamlessly shared with other applications or displayed within your store's theme, enhancing both user experience and data utility. The app supports easy integration by letting you independently add extra fields to the Shopify sign-up form in a few simple steps. It works harmoniously with existing metafield data type definitions and offers the convenience of reading and editing data directly from the customer page. Importantly, even if you decide to uninstall Amplius Customer Fields, you retain all the data you've accumulated, ensuring data persistence.
