No. Distil AI: Business Analytics uses Shopify APIs to extract and analyse your store data. The shopping experience is not modified in any way, installation of Distil AI: Business Analytics will have zero impact on the performance of your store (appart from helping you use your data to become more profitable of course!).  Optionally, you are able to extend the analytics provided by installation of our Engagement Javascript tracking code. This code has been designed to be fast and efficient, does not place any images or text on your pages and will not impact the performance of your store with the possible exception of a negligible load delay for the very first page-load after you have added the tracking code.
