Is Rex KeepAlive safe?
Rex KeepAlive sends encrypted session heartbeat reports with IP address, geolocation, and device fingerprint to Rex.
When a user is signed in on Rex pages, Rex KeepAlive reads the page token and stores a device fingerprint built from browser and screen details. About every hour, and when the token, device context, or IP address changes, it sends an encrypted heartbeat containing the public IP address, user agent, fingerprint, timezone, and geolocation to Rex.

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.
