Is Trainn safe?

Clean risk

Trainn records clicks, form focus, highlights, viewport details, and screen metadata during its recording mode.

When Trainn recording is active, its content script listens on every page for clicks, pointer events, input focus, scrolling, keyboard and mouse movement used for highlights, and viewport or screen details. It sends that event metadata through the extension background script to the active recording tab, which posts it to Trainn's app service.

Where it sends data

Destinations our analysis observed Trainn 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.
