Who makes TrustWords
An independent developer, in France, reachable by e-mail. The app was born from one call too many received by a parent. It is sold once or by subscription, with no advertising and no data resale: that is its only business model.
Why it exists
The usual advice assumes you keep a cool head: “be wary”, “ask a personal question”. The moment a familiar voice announces an emergency, you no longer have one. TrustWords does the opposite: it gives you something simple to check, and takes over when it doesn't add up.
How it was built
- Hundreds of sources went through: victims' forums, official alerts from France, the United Kingdom and the United States, press testimonies.
- A guidance path first written as a prototype, reviewed thirty-six times, then checked by automated tests at every change.
- A dedicated review for people aged 65 and over: contrast, target size, one thing per screen.
- Five languages, and the emergency numbers of more than two hundred countries.
What TrustWords does not do
- It does not analyse voices and does not detect deepfakes: it doesn't need to.
- It does not block calls and does not listen to your conversations.
- It does not replace your judgement: when in doubt, hang up and call back.
