Is Rex KeepAlive safe?
Rex KeepAlive sends hourly heartbeats with your public IP, device fingerprint, and precise geolocation to the vendor while you're signed in.
Once a user is logged in on rex.zone, the extension reads their login token from that site's storage and starts a background alarm that fires every 60 minutes (and immediately on any IP change) to record a work session. Each heartbeat bundles the public IP address, a FingerprintJS device fingerprint, timezone, user agent, and high-accuracy latitude/longitude (obtained via the geolocation permission), encrypts it, and posts it to the vendor's own backend. The extension's own popup discloses this purpose, describing it as tracking required work sessions for a compliance record.

What this publisher told the store about itself, and the other listings that told it the same thing.
Shared hosts - 4 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.

What it can do
Permissions this extension asks for, as declared in version 1.0.12. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.

Where it sends data
Destinations our analysis observed Rex KeepAlive 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.
