A different answer to phone scams.
QuietGuard launched on 4 July 2026. In its first three months it reached 160,000 installs on Google Play, rated 5.0 stars by its users. This page sets out the story, the traction and how to reach us.
01 Traction
Where we are today.
Figures for the QuietGuard app as of 6 October 2026, from Google Play. We update them here with the date each time.
02 The idea
Let in the trusted. Keep everything else quiet.
Scam calls and harmful websites are usually fought with lists of known threats. Those lists are always one step behind: a new number or a new site works until someone reports it.
QuietGuard works the other way round. When protection is on, only the people the user trusts can ring; every other call stays silent and is listed in a quiet log. QuietWeb does the same for the web: it opens only saved websites. Nothing has to be reported first, and nothing depends on an algorithm guessing who is safe.
It is private by how it's built: no databases and no cloud. QuietGuard runs on the phone and the trust settings stay there.
03 Who it's for
Four modes, one product.
Kids & Family
A safer first phone. Parents choose the trusted circle; the child can't switch protection off behind their back.
Personal
Fewer scam calls, quieter days, and an SOS button that knows where you are.
Family
The whole household protected with the same rules.
Business
The calendar decides who can interrupt you.
