Is Cookie Guard safe?

Medium risk

Cookie Guard writes detected affiliate cookie details into page-visible alerts and sessionStorage.

Cookie Guard displays detected affiliate cookie names, domains, and truncated values in alerts injected into the active page, and it stores the alert data in that page's sessionStorage. Because its content script runs on HTTP and HTTPS pages, a page that receives an alert can read those injected DOM and sessionStorage values. It also injects a Google Fonts stylesheet into HTTP and HTTPS pages, creating page subresource requests to Google Fonts.

Where it sends data

Destinations our analysis observed Cookie Guard contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
