Persistent Cart, answered.

No. On a default Shopify store the cart is stored in a browser cookie that lasts about two weeks — not on the customer's account. So when a signed-in shopper switches from phone to laptop, the cart doesn't follow them; it isn't there on the second device. Shopify's own community confirms cross-device cart sync needs custom code or an app.

No. By default Persistent Cart merges carts silently in the background — no popup, no email, no opt-in, nothing for the shopper to do. There's an optional "keep or combine" prompt you can turn on if you'd rather let shoppers choose, but it's off by default.

It works for logged-in (identified) customers. That's what makes cross-device sync possible — the cart can be tied to the account and restored wherever that customer signs in. Guests browsing without an account aren't tracked.

No developer needed. You install it in one click from the Shopify App Store, then enable the app embed in your theme editor — no theme code to touch. It starts working immediately.

It runs lightweight in the background and is Built for Shopify, which means it meets Shopify's performance and quality standards. Most merchants never notice it running — which is exactly the point.

Abandoned-cart email and SMS apps act after a cart is abandoned and only reach shoppers who opted in. Persistent Cart acts before — it keeps the cart from disappearing when a signed-in shopper switches devices, for everyone. They're complementary; many stores run both.

Only what's needed to sync a cart for a signed-in customer: the cart's contents (items, quantities, notes) tied to that customer for your store. It doesn't track guests, send emails, or capture marketing contacts. Data requests are handled through Shopify's required flows.

Yes. It's used across Basic to Plus, and it's well suited to B2B, where buyers build large carts across sessions and devices. On shared workstations, each signed-in buyer's cart restores correctly without leaking to another account.

Yes — every plan starts with a 30-day free trial. You approve your plan's charge when you install, which is what activates the app, but you aren't billed until the trial ends — and you can cancel anytime from your Shopify admin. Every plan includes the full app; your price simply matches your Shopify subscription level.

Yes. Billing runs through Shopify, so you can remove the app or cancel from your Shopify admin at any time.

No. As of 2026 the cart is still stored in a browser cookie rather than on the account, so even with new customer accounts a signed-in cart doesn't follow a shopper across devices and browsers natively. Persistent Cart adds that layer.

It works with multi-currency Shopify stores, and it syncs the cart regardless of language. The app is used by stores around the world — cross-device cart loss isn't specific to any one market.

Persistent Cart's dashboard shows the order value coming from transferred carts on your own store — measured, not estimated. For many stores that value runs to 1,000×+ what the subscription costs. Every plan starts with a free trial, so you see your store's own numbers before paying anything.

Yes. Persistent Cart works with Shopify's new customer accounts, and when a shopper signs in through the Shop app their cart is tied to their account just the same. Keep in mind that Shop sign-in by itself doesn't move carts between devices — Persistent Cart is the layer that keeps the cart in sync everywhere the customer signs in.

Until checkout — there's no time limit. The cart is stored against the customer's account and stays there until they buy or change it, whether they come back tomorrow or months later. On default Shopify, by comparison, the cart lives in a browser cookie for about two weeks.

For the most common wishlist job — keeping items so they're still there on the next visit, on any device — yes. A signed-in cart that follows the customer does what most shoppers actually use wishlists for: park items now, buy later, from whichever device they sign in on next. You skip a separate wishlist app, and the items are already in the cart when they're ready — one step closer to checkout, not two.

That journey is exactly where a default Shopify store loses carts. A shopper taps an ad on their phone, adds to cart, then comes back later on a desktop — and the cart is empty, so the ad spend that built it is wasted at the last step. With Persistent Cart, whatever they added on the phone is waiting after they sign in on the desktop. Merchants tell us this phone-to-desktop path is one of the most common ways a sale quietly dies.
