Is JSON Formatter safe?

Low risk

JSON Formatter loads HTML banners and links from linangdata.com into its popup each time it opens.

Each time the popup opens, the extension requests three HTML fragments from linangdata.com and inserts them into the popup, including links that open in new tabs to addresses the server chooses. The request carries a source tag and a timestamp-based ID. The extension's default page policy blocks inline scripts, so this is limited to content and link injection.

Where it sends data

Destinations our analysis observed JSON Formatter 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.
