ATLOCK

ATLOCK v4 — a single .exe, offline-first security suite for Windows. System Lockdown blocks Alt+Tab, Win key & Task Manager. File Guard uses NTFS ACLs so locked files can't be opened, copied, or deleted — not even by admin. Password Vault uses AES (Fernet) + PBKDF2-HMAC-SHA256 encryption, fully local, zero cloud. Intruder Ops auto-captures photo + 10s video on wrong attempts. No installer, no account, no subscription, no telemetry.
