Stats are collected by the AppMetrica service. We configured sales and ordering funnels to include info on adding to cart, moving to cart, pressing the "place order" button and so on.
The customer is provided with data on the amount of orders, registered users, user ages, check-ins, card linking and bonus points. This data helps to assess whether the app is successful and assists in tracking the efficiency of marketing campaigns; this info can be used to change the marketing strategy if the goals are not achieved.
