Tell it about your device. Get a checklist made for it.
HardenCheck asks a few questions about your device and threat level, then builds a personalized, plain-language security checklist you can work through and tick off. It runs entirely in your browser. Your answers never leave your device: no server, no telemetry, and it works offline.
