StarAC | Powerful AntiCheat v2

StarAC validates combat, movement, and packet behavior in real time using 3D RayTracing, rotation analysis, and AI-based cross-correlation, ensuring absolute accuracy without impacting server TPS.
StarAC and its lines of code are designed to collect player actions in order to validate whether a player is legitimate or using exploits. StarAC prefers to be safe before generating false positives.

Why is StarAC free?
Data collection (please read). StarAC continuously sends data to our servers to keep cheat detection accurate and improve it for everyone. This is a core part of how the plugin works and cannot be disabled. Two streams: (1) anonymous operational data (identifies a server, never a person); (2) anti-cheat improvement data — numeric movement/combat features and labels, with each player's UUID pseudonymized on your server (HMAC + a secret salt that never leaves your machine). We never collect player names, IPs, chat, or raw UUIDs. By downloading and running StarAC you accept our Terms and Privacy Policy, and confirm you are responsible for informing your players where your local law requires it.
