Is Gain safe?

Clean risk

Gain sends each logged-in user's HTTP(S) tab origin to gain.ai when navigation updates.

When the user is signed in, Gain's background worker watches tab updates, reduces HTTP(S) URLs to their protocol and host, and posts that origin to Gain's data.searchDomain RPC endpoint. The response is cached and used to update the extension badge and UI.

Shared hosts - 8 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 Gain 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.

  • gain.ai

    Gain sends data to gain.ai. No other extension we have analysed sends data here.
