Walk away & lock your computer

Only for Mac

Keep your computer and data safe by automatically locking it when you leave the computer. Walk Away. Stay Safe. ProximityLock automatically locks your computer the moment you walk away. Your iPhone, Apple Watch, or AirPods become an invisible security leash — no buttons to press, no shortcuts to remember, no habits to build. Set it up once, then forget about it. HOW IT WORKS Pick the Bluetooth device you always carry — iPhone, Apple Watch, AirPods, or any Bluetooth Low Energy device. Enable monitoring with a single toggle. When you walk away, your device's signal fades and ProximityLock locks your computer instantly. When you return and unlock, monitoring resumes automatically. That's it. Three steps, then never think about it again. SMART, RELIABLE DETECTION ProximityLock doesn't just watch for signal drops — it uses historical signal analysis to prevent false locks from brief interference, someone walking between you and your computer, or momentary Bluetooth fluctuations. A real-time signal graph lets you see exactly what ProximityLock sees, and you can visually drag the threshold and adjust the timeout to perfectly match your environment. Or just use the defaults — they work great. PRIVACY YOU CAN VERIFY ProximityLock was designed with one unbreakable rule: not a single byte of your data ever leaves your computer. • Zero Network Access — ProximityLock doesn't use networking APIs at all. It literally cannot access the internet. • No Data Collection — No analytics, no telemetry, no tracking, no cloud. Nothing is collected or transmitted. Ever. • Passive Listening Only — ProximityLock is a receiver, not a transmitter. It listens to Bluetooth signals your devices already broadcast. It never connects to or communicates with your devices. • Minimal Permissions — Only Bluetooth and Notifications. No access to your files, contacts, location, camera, or microphone. • App Sandbox — Runs in Apple's App Sandbox with the minimum possible entitlement. Even a bug couldn't compromise your data. • Verifiable — Use macOS network monitoring tools yourself. You'll see ProximityLock makes zero connections. FEATURES • Automatic Locking — Your computer locks itself when you walk away. Every time. • Signal Visualization — A beautiful real-time graph shows signal strength and lock events. • Battery Efficient — Passive BLE listening uses minimal power. Monitoring pauses during sleep automatically. • Works With Your Devices — iPhone, Apple Watch, AirPods, fitness trackers — any BLE device you already carry. • Fully Configurable — Adjust signal threshold and timeout, or use the smart defaults. • Set & Forget — Add to Login Items and ProximityLock launches silently at login, remembers your settings, and resumes monitoring. • Native macOS Design — Built with SwiftUI. Supports light and dark mode. Feels right at home on your computer. • Localized — Available in over 20 languages. WHO IT'S FOR Office workers meeting security compliance. Remote workers keeping things private from kids or visitors. Coffee shop regulars who need a refill. Students in libraries and shared spaces. Anyone who has ever walked away and forgotten to lock their computer. One-time purchase. No subscriptions. No in-app purchases. No advertising.
