【WARNING: This tool is brutally unforgiving. Zero comfort, zero mercy. If you’re not ready to face your weakness, do not buy.】 NullLock is not a habit tracker. It’s a cyber solitary confinement built into your phone. Designed for severe dopamine addiction (doomscrolling, vaping, sugar, all-nighters). True discipline needs no rewards — only sunk cost and physical consequence. Core Protocols • Brutalist visuals: dead-black void + one heavy industrial chain • Advanced haptics: successful lock = sharp metallic click 　　Hold to break = accelerating heartbeat vibration + shattering glass + heavy impact • Zero notifications: no alerts, no badges, no reminders • No escape: no retroactive edits, no skip days, no mercy 　　Every failure is permanently logged in the Forensic Audit 100% offline. Zero servers. Zero data collection. What happens on your device stays on your device. Spend the price of a coffee. Issue yourself a death order. Keep the chain unbroken. Or destroy it with your own hands.
