Dynamic Banner Suite requests a few permissions when you install the app. Permissions and the reasons for them are listed below:
View products: This includes products and collections. Products are required so that we can display the product carousel for a particular discount.
Edit other data: This includes price rules. Data editing is required so that we can install the banner javascript in your shop.
Edit your online store: This includes script tags in your online store. Editing is required so we can read and write the discount codes you may want to use.
