Loud isn't enough.
You have to be believed.
Every other alarm discards the 90 seconds that matter most — the ones beforeyou pulled the pin. ProofGuard keeps them: it alerts the people who'll actually come, streams your live location, and locks timestamped audio of what happened. On guard the moment you feel it.
When did you last run toward a car alarm?
You didn't. Nobody does. The world has trained itself to ignore loud.So an alarm whose whole idea is “be as loud as possible” inherits that problem the day it ships — it begs strangers to care, and strangers have stopped.
ProofGuard doesn't beg strangers. It tells the people who'll actually come — and it keeps the proof.
“Do you have any evidence of that?”
The sentence “it was their word against mine” doesn't come during the incident. It comes after — at the police station, in the HR meeting, in the conversation with a welfare officer or a solicitor. The moment the person taking your statement looks at you with that particular careful expression and asks whether you can prove it.
That gap isn't physical distance from danger — loud alarms cover that. It's evidential: the space between surviving the moment and being believed afterward. ProofGuard was built to close it.
The Evidence Loop
Every other alarm stops at step one or two. ProofGuard runs the whole loop — protecting you in the moment and documenting it for after.
Trigger
Three ways: pull-pin, button, or a spoken keyword you set in advance. Whatever's fastest when your hands aren't free.
Deter
Optional · situationalAn optional 130dB siren — around the human pain threshold, comparable to a jackhammer or ambulance siren, audible roughly 100–150m in the open. Loud when noise helps; silent when silence is safer.
Alert
Your named contacts get a text and a phone call — the people who know your voice and will actually move. Not a monitoring centre. Not strangers.
Locate
Live GPS streams to your people from the moment you activate — moving as you move, so they know exactly where you are.
Prove
The part nobody else doesTimestamped audio locks on activation — including the 90 seconds before you triggered. A record of the escalation, not just your word.
Real fear isn't a single button.
Everyone else gives you one panic button — all or nothing. ProofGuard has two modes, because the scariest moment is the one where you're not sure yet.
Someone's walking behind you. You're probably fine. But you arm it anyway.
Silent. Your location quietly streams to your people and the 90-second audio buffer rolls in the background. No siren, no fuss — and if it turns, everything that led up to it is already captured.
Same night. Two completely different mornings.
You have your memory. Your account. Your word — which is true, and which matters, and which will be weighed against another account in a process that depends on more than memory.
You have a timestamp. 90 seconds of audio that were already running before you knew you'd need them. GPS showing exactly where you were. A record that exists independently of what either party says afterward.
The difference isn't being more afraid. It's being prepared for both problems — the moment, and what comes after it. ProofGuard solves both.
