Does Shipping Rates Calculator+ modify my theme templates?

The Shipping Rates Calculator+ app does not need to modify any of your templates to run nicely in your store. We use a Shopify programming feature called ScriptTag that allows our app to be injected dynamically by Shopify when a page loads.

While the ScriptTag feature is very convenient, scripts that run that way have to wait till other content on the page is loaded, which can be perceived as the app is slow.

To avoid that and load quickly, we provide the option to insert our app script in your main theme template (theme.liquid). This option is called 'Fast loading' and can be configured on the app preferences page. Please note that this is optional, so you can avoid that one-line modification of your theme template by disabling the 'Fast loading' option in 'Advanced preferences'.

On the other hand, to ensure maximum compatibility with some Shopify themes, our app could make minor cosmetic changes to your theme when the app is installed or when the main theme is changed. This is controlled by the 'Autoconfigure' option that can be disabled on our app preferences page.

Finally, our app script may be upgraded automatically from time to time to take advantage of the latest features implemented in the app. This can also be disabled with the ' Autoconfigure' option.
