Is Fastcup Enhancer safe?

Low risk

Fastcup Enhancer sends Steam profile IDs from FastCup pages to fastcup-enhancer.igoryusha.love with a persistent user ID.

On FastCup match and player pages, the content script looks for Steam profile links and requests /api/v2/profile for each Steam ID it finds. Those requests go to fastcup-enhancer.igoryusha.love and include an App-User-Id header derived from the browser profile ID when available or a generated UUID stored locally.

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