Nero: Merge Duplicate Products ("the app") is made by Nero Labs, a trading name of Nero Engine Group Ltd, a company registered in England and Wales. Contact: founder@neroengine.com.

What the app does

The app reads a Shopify store's products to find duplicates and look-alike products, and, only when the merchant asks it to, merges them into one product with options, archives the originals, sets up web address redirects and can undo the merge.

Information we process

• Product data: titles, descriptions, options, variants, prices, SKUs, barcodes, stock levels, images, tags, collections and sales channels, read and written through the Shopify Admin API.
• No customer data: the app does not request or store any information about the store's customers or orders.

What we keep

The list of look-alike groups from the latest scan, the merchant's plan, and for each merge a backup copy of the original products' data so the merge can be undone.

Who we share it with

Nobody, except Cloudflare, which hosts the app and its database. We do not sell data or use it for any other purpose.

Deleting data

When a merchant uninstalls the app, Shopify sends a shop data deletion request 48 hours later and we then delete everything we hold for that store, including merge backups. Contact founder@neroengine.com with any privacy question.
