We built Amazon Seller Sync to do one job well, keep your Shopify store and your Amazon Seller Central account in sync, while holding as little of your data as possible and protecting everything we do hold. This page explains, in plain language, exactly how.
In one sentence
We never collect your shoppers' personal details for the everyday price, product and stock features; the secure keys that let us work on your behalf are always encrypted with bank-grade AES-256; and everything travels over an encrypted (HTTPS) connection.
What we hold to run the app:
.myshopify.com address, store name, contact
email, country and currency.What we deliberately never do:
The one exception, and it's your choice: if you turn on Amazon Multi-Channel Fulfilment (letting Amazon ship your Shopify orders), we pass the delivery name, address and phone number for each order to Amazon so your parcel can be delivered. That information is used at the moment of fulfilment and is never saved in our systems.
| Information | Whose | Do we store it? | Why |
|---|---|---|---|
| Store email, name, country | You (the merchant) | Yes | Support, billing, running the app |
| Shopify & Amazon permission keys | Acts on your behalf | Yes, encrypted | To sync prices, products and stock for you |
| Shopper delivery details | Your customer | No, only passed to Amazon to ship, if you enable fulfilment | Deliver the order |
| Shopper email / payment details | Your customer | Never accessed | Not needed |
When you remove the app, your permission keys and app data are wiped straight away. Shopify then sends a final deletion instruction about 48 hours later, and all remaining data for your store is permanently deleted. Nothing lingers.
We support your rights under GDPR / UK GDPR, including access, correction and erasure of your data. Uninstalling triggers deletion automatically, and you can contact us any time for a data export or a specific request.
To run the service we rely on a small set of reputable, security-certified providers: Shopify (the platform), Amazon (the Seller Central integration), our cloud host, and Microsoft (for staff sign-in only). If you enable AI-powered content features, product text, never customer data, may be sent to an AI provider, and you can use your own provider account.
We're happy to help with security questionnaires and due diligence. A detailed data-handling and security document is available to customers and auditors on request (under NDA where appropriate).
