No wrappers. Built on Network.framework, Security.framework, OSLog, and SwiftUI. Every tool runs natively on your device. PRIVACY FIRST No analytics. No tracking. No ads. All tools run locally — nothing about your network, system, or lookups is transmitted to any server operated by ComDeck. HONEST ABOUT THE SANDBOX Some system-level checks (FileVault, firewall, system-wide processes) require admin privileges unavailable to sandboxed apps. ComDeck does not fake these results. The Security Scanner clearly labels which checks are intentionally skipped and why, so the data you see is real. TIER POLICY Higher tiers include all tools from lower tiers.
