How does Honey extension capture data?

[wanderingMonk]

I am using Honey and going through their FAQ and in below link it is mentioned that they collect some data from shopping website and if user made a purchase or not. I want to know if if Honey is capturing cart data and how do they do it? Through data scraping on checkout/payment page? and how does it know that is purchase happen or not?

I use honey, but I only enable it on the page before I'm about to check out, then disable it after it's found a discount.

Granted, during the time it is activated they could do whatever they want with my data (including hijacking my session), but at least this way they don't track everything.

But during the time you activated the extension, it can access what items are in your cart, right?

Being a browser extension, they can access the URLs, and HTML data of the web pages their users visit.

Then checkout HTML page will have cart items information also, so basically it is scraping the that data from page?
