About
We make technology quieter and safer, by letting people choose.
Controlled Systems Group makes the QuietGuard family of apps. We believe the people on your phone and the websites on your screen should be the ones you chose.
01 What we believe
Three principles.
Your circle, your call
The person decides who is trusted, and can add or remove people at any time. Protection is based on people you name, not on algorithms guessing who is safe.
Private by design
No databases, no cloud. Our apps run on the device, and trust settings stay there.
Calm, not alarming
Every setting is visible and extra tools are off until you switch them on. We explain risks plainly and never use fear to sell.
