Yes — play on your normal account. The standing, audited statement: the client does not read, write, inject into, hook, or open a memory or module handle to the Day of Defeat / Half-Life game process. It interacts with the game through four channels only — screen capture via the same API OBS and Xbox Game Bar use, passive read-only input observation, read-only file hashing, and process-name enumeration.

That statement is re-verified against every release by two independent whole-codebase audits, run before the build is published, and nothing found contradicts it. VAC's concern is software that opens the game's process and memory; this client structurally never does.

A flag is a request for human review, not a verdict. The server re-scores every session from the raw evidence, and a person reads every flagged session before anything happens. Legitimate hardware and setups trip detectors sometimes — Hall-effect keyboards, custom HUDs, sound mods — and the release history is full of exactly those cases being fixed in the detector, not held against the player. If a result looks wrong to you, ping a KTP admin in the Discord and they'll walk through the evidence with you.
