DoubleProof

Made for adult children who worry about their parents: one family rule for strange phone calls — a secret code word, a calm callback, and a plan everyone knows before the phone rings.

How it works

1
Your family agrees on a secret code word and two trusted phone numbers.
2
DoubleProof turns it into one plan card — a link and a QR code you can print or send.
3
When a scary call comes, nobody has to think. They follow the card: hang up, call back, check the word.

Why a code word and a callback?

Today a phone call can sound exactly like someone you love — voice-cloning tools can copy a voice from a short recording. Panic makes people act fast, and fast is what a scam needs.

A code word can't be copied from a voicemail. And hanging up to call back on the number you already know breaks the script: a real family member will still be there in two minutes; a scam usually won't.

This is not about being suspicious of everyone. It's about giving your family one calm, agreed step so a frightening call becomes a routine one.

Pick something your family will remember but wouldn't say online. Never post it anywhere.

Two trusted numbers

Our plan rules

Private by design: your code word and phone numbers are never sent to us and are not saved on any server. Your plan lives inside the link itself — and, when you save it, only in this browser on this device.
Please read: DoubleProof is a family plan, not a bank or police service. It cannot guarantee protection — it makes the safe step the easy step. If someone may be in real danger, call your local emergency number first.
