Does Frequently Bought Together modify my theme templates?

The Frequently Bought Together app does not need to modify any of your templates to run nicely in your store. We are using the App Embed Block system from Shopify (see https://shopify.dev/docs/apps/online-store/theme-app-extensions/extensions-framework#app-embed-blocks for further explanation).

It handles the injection of our app on your theme, without interfering with or manipulating any file in your store.

Auto-configuration preference

In order to ensure maximum compatibility and, work out of the box with some Shopify themes, our app could make minor cosmetic changes to the app preferences or your theme when the app is installed or when the main theme is changed.

This is controlled by the Auto-configuration preference that can be disabled on our app preferences page → Advanced preferences.
