Why People Lose Money
Scammers do not need sophisticated technology. They need time, pressure, and an unanswered call from a stranger.
Unknown callers
Scammers deliberately keep victims on the phone long enough to build fear, urgency, and false trust.
Psychological pressure
The longer the conversation lasts, the easier it becomes to push someone into a risky decision.
Families find out too late
By the time someone realizes what happened, the money is often already gone.
CallGuard interrupts the attack.
How it works
A simple safety boundary around unknown calls that last longer than your family has chosen.
1
An unknown number calls
2
The call is answered
3
CallGuard starts the timer
4
The chosen time limit is reached
5
CallGuard ends the call and sends an SMS to the Guardian
CallGuard does not identify scammers and does not block all unknown calls. It creates a practical safety boundary when an unknown call lasts longer than your family has chosen.
A trusted Guardian knows when to check in
Choose one trusted person to receive an SMS alert. It could be an adult child, partner, sibling, or close friend. The Guardian can then contact their loved one and make sure everything is okay.
