Read before you scan.
Before each scan, ACS shows the configured server and explains access to running processes, loaded modules, drivers and bounded game-memory evidence.

02 / YOUR DATA, YOUR DECISION
Know what a scan can see.
Know what is sent.
Reports can contain player and device identifiers, paths, hashes, signature status, memory strings, game/server information, findings and timing.
Decide before it starts.
The report uploads automatically when the scan finishes. Choose Cancel on the screen before scanning if you do not want it sent — there is no second prompt.
Server access and retention are operator-controlled.
Records may remain until the operator deletes them. Ask about private access, retention and deletion before scanning. The executable uses cslonghorn.com by default and obtains a temporary upload session.

No independent audit, verified antivirus verdict, or real-world detection-rate benchmark is claimed. Tests exercise selected behaviors; they are not a malware certification. ACS does not claim to detect every cheat or prevent every bypass.
Keep Windows and antivirus protections enabled. Review unexpected warnings and use software only when you trust its source and operator.
Report a security concern →04 / COMMON QUESTIONS
Before you start.
Why is the scanner source private?
The maintainer distributes compiled releases while keeping detection implementation private. Public documentation describes data access and limitations. Private source does not prevent reverse engineering, and is not proof of safety.
Does it run continuously or install a driver?
No. ACS is a single on-demand executable. It installs no background service or driver. Continuous server gameplay analysis is a separate deployment.
Does a clean scan prove someone is not cheating?
No. A scan is a bounded observation. Unknown cheats, unavailable inspection surfaces and evasion can affect results. Warnings and detections need review before enforcement.
Where do I get the report server settings?
Ask your game-server operator for their acp-settings.json and place it next to the executable or in %APPDATA%\LongHorn ACS\. GitHub Pages hosts this information site, not the report API.
Is this endorsed by Valve, Microsoft or GitHub?
No. Counter-Strike and other product names identify compatibility targets. Hosting on GitHub and bundling Microsoft runtime files do not imply endorsement.
