FAQ

Casper — frequently asked questions.

What is Casper on Shopify?
Casper, officially listed on the Shopify App Store as Casper ‑ Persistent Cart Sync, is a Shopify app in the Abandoned cart category. Casper saves each logged-in customer's cart and syncs it across their devices. A saved, cross-device cart stays persistent for 90 days, so customers returning later or switching device find their cart exactly as they left it. This cuts abandoned carts and drives automatic cart recovery, with no pop-ups, no restore button and no setup. Track cart history and insights to spot buying intent. For wholesale and B2B stores, turn any large saved cart into a draft order in one click. It averages 4.70 out of 5 across 29 merchant reviews on the Shopify App Store.
