No. The words are computed on each phone from a shared secret — like Google Authenticator. It works with no signal, on a plane, abroad. The only internet needed is once, during family setup.
If she can read three words aloud, she can use FamWord. That's the whole interaction. Setup is done by you, on her phone, in person.
A static safe word can be overheard, leaked, or guessed. FamWord words change every 30 seconds — like a bank code, but made of simple words you can hear clearly over a bad phone line.
The scammer is on a phone call, not in the room. And since the words rotate, yesterday's words don't help today. For setup, you scan the code face-to-face.
Nothing. Your family's secret never leaves the phones. There are no accounts, no phone number book, no servers holding your words. We literally cannot see them.
One family is free, always. Extended family (up to 6 people) will be a few dollars a month. No ads, no data selling — ever.
