Is Split Desktop Extension safe?

Clean risk

Split Desktop Extension sends each visited site's domain to api2.split.co and can redirect tabs to affiliate links.

On every page navigation the extension sends the site's domain, along with the user's Split auth token, to Split's API to check cashback eligibility. On Google search pages it also sends the result domains. When auto-shopping is enabled and a merchant is eligible, it sends the full page URL to Split and navigates the tab to the affiliate URL it returns.
