Is Tailscan safe?

Clean risk

Tailscan sends selected page HTML and your prompt to its Cloud Functions endpoint for AI DOM editing.

When you use Tailscan's AI DOM editing feature, the extension reads the selected element's HTML from the current page and sends it with your prompt and license key to Tailscan. The request goes through the extension background script to the Tailscan Cloud Functions endpoint for prompt-based DOM manipulation.

Where it sends data

Destinations our analysis observed Tailscan 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.
