Is Jace Gmail Extension safe?

Low risk

Jace Gmail Extension sends a bundled bearer token to a Zeta Labs dev API when its popup polls thread data.

The popup includes a hardcoded JWT and attaches it as an Authorization bearer token when requesting /api/threads from the Zeta Labs dev server. Opening the popup triggers repeated thread polling every three seconds with an after_timestamp query for the previous week.

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

Where it sends data

Destinations our analysis observed Jace Gmail Extension 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.
