What is Rex?

REX HAS A MISSION: To reduce the number of stolen MacBooks on the planet.

REX PROTECTS WITHOUT CONSTANT MANUAL ARMING AND DISARMING

? Smart Always-armed Mode: Rex's carefully designed behaviors keep your MacBook safe, without you having to think about it ? Rex alarms immediately when: ...your MacBook is closed ...the screen is locked and your power is pulled ? Unlocking your MacBook by TouchID or password automatically clears in-progress alarms ? Pack-up grace window (~10s) — lock ? close lid within 10s let's Rex know you're packing up and should disarm ? ...and Rex re-arms automatically the next time you open your MacBook

REX PROTECTS IN WAYS OTHERS DON'T

? Headphone-proof: Forgot your headphones plugged in? No problem. ...Rex always plays alarms (loudly) through your MacBook’s built-in speakers. ? Muted your volume? No problem. ...Rex overrides volume settings to play alarms, and restores volume settings when alarms are cleared.

PUSH NOTIFICATIONS

? Real push notifications to your phone - you know instantly when an alarm is triggered or clears ? ...for those that prefer it, we also support notifications via Telegram or Webhook ? Telegram integration — alerts to your bot/channel; tokens stored in Keychain ? Webhook callbacks (HTTPS) — pipe alarms into automations, incident channels, or your own systems

CUSTOMIZABLE

? Custom arming configuration for those who prefer full manual control ...customize every aspect of Rex's behavior ? Multiple siren choices — pick the sound you want people to notice

TRUSTWORTHY

? Privacy-first by design: all logic runs locally on your MacBook ? No cloud account, no analytics SDK, no ad tracking, no location services ? No data ever leaves your device, except notifications that you choose to receive ? No asking for your phone number or personal details

Rex is Perfect for • People who work from cafés and shared spaces • Digital nomads and frequent travellers • Students in libraries or campus lounges • Anyone who wants a “set it once and forget it” alarm for their MacBook

Install Rex on your MacBook, enable Smart Always-Armed mode, pick your alarm sound and push notifications, and carry your laptop with more confidence.
