Is DesignHub safe?

Medium risk

DesignHub sends typed omnibox search terms to suggesting.designhubapp.com over unencrypted HTTP.

When you use its omnibox keyword, the background script appends the text you type as a q parameter to an HTTP request for search suggestions. The response is used to populate suggestions, so suggesting.designhubapp.com receives the typed search terms before you submit them.

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

Shared hosts - 2 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 DesignHub 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.
