Is Highlight Emails in Gmail by cloudHQ safe?

Low risk

Highlight Emails in Gmail by cloudHQ sends signed-in Gmail account addresses to www.cloudhq.net during Gmail startup.

When Gmail loads, the extension reads the current InboxSDK Gmail address and checks Gmail account switcher entries for additional signed-in addresses. It posts those addresses and extension metadata to cloudHQ's pre-user check endpoint, with local storage only limiting how often the automatic check repeats.

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

Shared hosts - 1 hostname

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.
