Casper runs silently on every page of your store, syncing carts for logged-in customers across all their devices. Cart updates are detected automatically, and carts stay active for up to 30 days, even when switching browsers. By avoiding pop-ups or disruptions, Casper keeps the buying experience smooth. It helps prevent lost checkouts by making sure customers always find their cart when they return.
