FAQ
Straight Answers Before You Install
What does Cart Bump add to the cart page?
A single add-on offer card, rendered by your own theme as a theme app extension block. A shopper taps the button and the product is added through your own store cart endpoint, with no redirect and no popup.
Does Cart Bump take a share of the extra revenue?
No. The free tier runs one bump slot with full styling at no cost, and Pro is a flat $4.99 a month with a 14 day trial. There is no revenue share and no per-order fee. The $4.99 is a founder price: after the first 25 paying stores or 31 January 2027 it becomes $9.99 for new stores, and existing subscribers stay on $4.99.
Does Cart Bump collect shopper data?
No. The storefront block sets no cookies, sends nothing to our servers, and reads no customer information. The only thing stored is your store domain, an access token and your plan status, all deleted when you uninstall.
