Is Dutycast safe?

Low risk

Dutycast sends the current page URL from every site to its config API with a persistent extension UID.

Dutycast injects a content script on all websites and requests configuration for the page you are viewing, forwarding the page URL to its API with App-Ref and App-Uid headers. For selected shopping sites, remote configuration can also show a prompt that activates a PAC proxy routing matching domains through a hardcoded proxy server.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Where it sends data

Destinations our analysis observed Dutycast 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.
