Is FACEIT Mappio safe?

Low risk

FACEIT Mappio sends Faceit matchroom player profiles and demo URLs to Mappio analysis servers.

On subscribed matchroom flows, the extension collects match IDs, selected faction and map, player nicknames, Steam IDs, avatars, ELO, demo URLs, and a JWT, then posts them to the Mappio analysis backend. It also sends match prediction, role, and skin-battle request payloads from Faceit pages to Mappio function endpoints.

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