Is Cassidy safe?

Medium risk

Cassidy can send webpage text and selected screenshots to app.cassidyai.com when page messages trigger its bridge.

Cassidy runs a content script on all websites and listens for page messages without checking the message origin. A matching message can make it convert the current page DOM to markdown, send up to 30,000 characters to the Cassidy iframe, or start a screenshot flow that captures the visible tab after a region is selected.

Where it sends data

Destinations our analysis observed Cassidy 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.
