A smart sticker that lets anyone reach you — without knowing your phone number
KnoQ gives you privacy-first reachability. Stick it on your car, door, pet collar, or luggage. Anyone who needs you simply scans the code — no phone number shared, ever.
Why KnoQ?
Every time you write your phone number on a car dashboard note, a luggage tag, or a door sign — you expose yourself. Your phone number is tied to your identity, your accounts, and your privacy.
phone scam reports filed globally each year
pets go missing annually worldwide
bags mishandled by airlines every year
people have had a package stolen from their door
There's a better way. KnoQ lets anyone reach you through a simple QR code scan — without ever knowing your phone number, email, or name. Private, encrypted, and free.
Imagine this...
KnoQ works wherever you need to be reachable — without sharing your phone number.
Vehicle
Your car is double-parked or blocking someone. They scan the KnoQ sticker on your windshield and reach you instantly.
Get contacted about your vehicle without sharing your phone number.
Home / Office
A delivery arrives while you're away. The courier scans the KnoQ code on your door and connects with you in seconds.
Never miss a delivery or visitor — respond from anywhere in the world.
Pet
Your pet slips away. A kind stranger finds them, scans the tag on the collar, and video-calls you immediately.
Reunite with your pet faster — the finder sees you and your pet on video.
Luggage
Your bag ends up on the wrong carousel or gets left behind. Someone scans the tag and reaches you before it's lost for good.
Recover lost luggage quickly without exposing personal details.
Others
Attach a KnoQ code to anything valuable — electronics, keys, equipment. If it's found, the finder reaches you privately.
Protect any valuable item with a simple, scannable code.

How KnoQ Compares
Sharing your phone number
Lets anyone call or text you directly — but exposes your identity, accounts, and personal data.
KnoQ lets anyone reach you without knowing your number. No identity exposure, no spam risk.
Apple AirTag / SmartTag
Tracks the location of lost items — but only notifies you. The finder has no way to contact you.
KnoQ lets the finder contact you instantly via encrypted video call or chat. Faster recovery, zero tracking.
Ring Doorbell
Records video of visitors at your door — but requires hardware, a subscription, and cloud storage.
KnoQ connects you live with the visitor. No hardware, no subscription, no cloud recordings. Just a sticker.
