Is Upromise Extension safe?

Clean risk

Upromise Extension checks each page you visit against a merchant list and redirects matches through its affiliate link.

The extension watches web navigations in your browser and compares them locally to a merchant list downloaded from its CDN. When a merchant matches, it sends you through an affiliate-tracked redirect on api.upromise.com, after checking for existing affiliate cookies from other networks. It also downloads coupon-script definitions from the same CDN and injects them into merchant pages.
