Similarwise privacy policy

Last updated 17 October 2026.

Similarwise is a Shopify app made by Colourmedia. It tracks the public storefronts of competitor stores a merchant chooses. This policy explains what information Similarwise handles when a shop installs it, why, and how long it is kept.

Information from the shop

When a merchant installs Similarwise, the app keeps:

• the shop's domain and the access Shopify grants the app, so it can show its pages in the admin;
• the list of competitor websites the merchant adds.

Similarwise does not store any information about the shop's customers or orders.

Information about competitor stores

For each competitor, Similarwise reads only public pages anyone can visit: the home page (for the theme, apps and tracking pixels it loads) and, for Shopify stores, the public product catalogue (product names, prices and publish dates). It keeps a history of those details so it can show what changed. It holds no personal information from those stores.

Early-access waitlist

If you join the waitlist on our website, we keep your email address, your store's website if you give it, and your survey answers. We use them only to tell you when Similarwise opens to more stores and to decide what to build. We don't share them. Email us to have them deleted.

How long it is kept

When a merchant removes a competitor, its history is deleted at once. When a shop uninstalls Similarwise, Shopify tells the app 48 hours later and everything held for that shop is deleted.
