A Walmart account lets you "access your cart across multiple devices."
Shoppers switch devices constantly.On a default Shopify store, their cart doesn't follow.
A shopper fills a cart on their phone, opens your store on their laptop — and the cart is empty. No error, no email, just a lost sale. Persistent Cart fixes it in one click (plus one switch in your theme editor): every signed-in cart follows the customer to every device, the way Amazon and Walmart already work. Nothing for shoppers to do.

The leak most owners never see
Your store probably drops a signed-in cart the moment a shopper switches devices.
On a default Shopify store, the cart lives in a browser cookie — not on the customer's account. So when a logged-in shopper adds items on their phone at lunch and opens your store on a laptop that night, the cart is empty. Most owners never see it happen, because nobody emails to say "my cart vanished." They just don't check out.
Default Shopify
The cart stays on one device
Phone cart and laptop cart are two separate carts. Switch device, lose the cart. No error, no email — just a smaller order or no order.
With Persistent Cart
The cart follows the customer
The signed-in cart syncs across phone, laptop, and return visits automatically — the same way the biggest retailers already work.
It's the difference between a cart that belongs to a browser and a cart that belongs to your customer.
9 in 10 people move between devices to get things done, and 88% of shoppers expect a consistent experience across devices and channels.Google/Ipsos, 2012 · Bazaarvoice Shopper Experience Index, Nov 2024
What changes after one click
Three things start working the way shoppers already expect.
Recover carts you never knew you were losing
Every signed-in cart that used to vanish on a device switch now survives to checkout — carts your email flows never even saw, because the shopper never abandoned, they just changed screens.
Bigger orders, because carts keep growing
An uninterrupted cross-device cart accumulates. Shoppers add on mobile, add more on desktop, and check out once — instead of rebuilding a smaller cart from memory.
One click, and nothing changes for shoppers
No popups, no emails, no opt-ins, nothing for customers to do. It runs silently in the background — so quietly that merchants tell us they forget it's on.
How the biggest stores already do this
Amazon and Walmart keep a signed-in cart on every device. Shoppers expect yours to, too.
This isn't a nice-to-have feature — it's the baseline experience at the stores your customers shop most. Their own help pages say so:
"Items added to your Shopping Cart will be available from any compatible web browser or Amazon Mobile app that has been signed in to your account."
The cart is stored in a browser cookie, so a signed-in customer's cart doesn't follow them to another device or browser.

In a merchant's words
Without the app, customers lose their shopping cart if they switch devices… This is NOT how all of the large online retailer websites function… the cart effectively stays with the Customer ACCOUNT rather than just the DEVICE.

Questions, answered
What merchants ask before installing.
Doesn't Shopify already sync carts across devices?
No. On a default Shopify store the cart is stored in a browser cookie, not on the customer's account — so a signed-in shopper's cart doesn't follow them to another device or browser. Shopify's own community confirms this needs custom code or an app. Persistent Cart is that fix.
Will my customers see popups or get emails?
No. By default Persistent Cart merges carts silently in the background — no popup, no email, no opt-in, nothing for the shopper to do. An optional "keep or combine" prompt is available if you'd rather let shoppers choose, but it's off by default.
Does it work for guests, or only logged-in customers?
It works for logged-in (identified) customers — that's what makes cross-device sync possible, because the cart can be tied to the account. Guests browsing without an account aren't tracked.
How hard is it to install?
One click to install from the Shopify App Store, then enable the app embed in your theme editor — no theme code, no developer. It starts working immediately.
Will it slow down my store?
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's running — which is the point.
How is this different from my abandoned-cart email app?
Those tools act after a cart is abandoned and only reach opted-in contacts. Persistent Cart acts before — it keeps the cart from disappearing when a signed-in shopper switches devices. They're complementary: use both.
How do I know it's worth it for my store?
Test it on your own store before paying: the Free Starter plan runs up to 10 real cart syncs, and any paid plan adds a 30-day trial. On Basic it's $4.99/month — recovering a single mid-sized cross-device order more than covers it. You can watch it work on your own store before a dollar is charged, so you're not guessing.
What does it do with my customers' data?
The minimum a cart sync needs. It works only for logged-in customers and stores the cart's contents against the customer's account for your store — nothing more than what a cart contains. Guests aren't tracked, no emails are sent, no consent prompts appear, and the data stays scoped to your store. We're Built for Shopify and follow Shopify's required data-protection flows.
Give your customers the cart they expect — on every device.
Add Persistent Cart in one click — from that moment, signed-in carts follow your customers everywhere.
