UR: Persistent Cart｜Cart Sync

Keeps a logged-in customer's cart the same across phone, tablet, and computer. Shoppers add items on one device and find an empty cart on another, so they give up or add everything again. This app saves the cart automatically and restores it on return—no buttons, no popups, nothing to click. If an item is unavailable, the shopper sees a simple notice instead of a silent failure. Cart data stays only in the store's customer records. Admin and storefront support 20 languages.
