Is 楽天ウェブ検索 safe?

Medium risk

楽天ウェブ検索 sends batches of visited URLs, referrers, redirect chains, browser details, and a Rakuten cookie to Rakuten.

On page loads, the extension collects the current URL, page referrer, redirect information, user agent, operating system, toolbar ID, and a Rakuten Rz cookie. It batches those records according to remote Rakuten Bar configuration and posts them to a Rakuten-provided endpoint.

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

Rakuten Group Inc

Shared hosts - 21 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 楽天ウェブ検索 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.
