Is Chrono Download Manager safe?
Chrono Download Manager fetches and executes a JavaScript library from its remote server without an integrity check.
The extension's service worker intercepts requests for an internal library file and serves it from app.chronodownloader.net instead of the bundled copy. The remote file is cached locally for 20 hours, but no Subresource Integrity check is applied, so any content served by that server runs with the extension's full permissions — including scripting, downloads, tabs, clipboard access, and webRequest.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 3 hostnames
Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data
Destinations our analysis observed ChronoDM 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.
- app.chronodownloader.net
ChronoDM sends data to app.chronodownloader.net. No other extension we have analysed sends data here.
