STEP 01
Stick it on your windshield.
Peel, place inside the bottom corner of your windshield facing out. Visible from the sidewalk; weatherproof for the long haul of UV, heat and ice.
01 Reachable. Private. Public-facing.
Get reached without giving out your number.
GlassPing is a small QR sticker for your windshield — visible from outside, ready to scan. Anyone who needs to reach you sends a quick message or photo. You get an instant ping on your phone. Your number never leaves your pocket.
Number never visible
Instant push pings
No app for the scanner
02 How it works
Three steps, then never think about it again.
Stick it on the outside of your windshield once. After that, it just sits there — visible, ready, quietly waiting for the day someone needs to reach you.
STEP 02
Anyone scans, no app needed.
A passerby points their camera at it. A simple message form opens — they type, optionally attach a photo, hit send. No download, no account.
STEP 03
You get pinged. Instantly.
A push notification lands on your phone in seconds. Reply if you want, ignore if you don’t. Your number stays private the whole time.
03 Why people use it
Small problems. Big relief when they happen.
You’ll forget your sticker is even there — until the moment it saves you a tow, a fight, or a flat battery.
Blocked someone in
They reach you in five seconds, you move. No notes shoved under wipers, no honking match.
Headlights on, flat tire
A stranger spots a problem you can’t see. You hear about it before the battery dies or the parking meter expires.
Minor parking incident
An honest neighbor leaves a photo and a timestamp. You have a record, not a mystery dent.
EV charging coordination
“Mind unplugging when yours is full?” A polite ask, a quick reply, no awkward sticky notes on the charger.
Lost item near your car
Wallet on the curb? Keys near the wheel? Whoever finds them can flag you without hunting for your number.
Fleet & delivery vehicles
One sticker per van. Customers reach the right driver instantly without published numbers or call centers.
04 Privacy by default
Your number stays yours.
GlassPing was built so the helpful stranger can reach you and absolutely nothing else can. Messages flow through us; your phone number doesn’t.
Anonymous to the scanner
They never see your number, name, or email — just a message field.
No data selling, ever
No advertisers, no brokers. We make money when you buy a sticker — that’s it.
GDPR & CCPA compliant
Export, edit or delete your data any time. We treat it as borrowed, not owned.
Auto-delete after 90 days
Old messages don’t pile up forever. They expire — quietly, automatically.
End-to-end anonymous
A scanner messages your sticker. We pass the message to you. Neither of you sees the other’s contact info — unless you choose to reply.

06 Frequently asked
Questions worth answering before you buy.
Do I need to download an app?
Scanners don’t — they just point a camera at the sticker and a normal web page opens. As the owner you’ll add the GlassPing web app to your home screen so push notifications work; no App Store download.
Is my phone number visible to anyone who scans?
No. We never share your phone number, email, or name. Scanners see a message form and that’s it. If you want to reply with your number you can — but only when you choose to.
What if I lose access to my edit link?
Sign in at app.glassping.com with the email you used at checkout — we’ll send a fresh magic link to take over your sticker. The QR code itself never changes, so you don’t need to peel anything off your windshield.
How durable is the sticker on a windshield?
It’s printed on UV-stable polyester with an automotive-grade adhesive designed for the inside of glass. It survives direct sun, freezing winters, and car washes. Tested through 18 months of windshield mounting without fading or peeling — and the QR contrast is tuned to stay scannable through tinted windshields.
Where exactly on the windshield should it go?
Inside the lower passenger-side corner, facing outward. It’s the standard registration-sticker zone — clear of your driving sightline, legal in every US state and most EU/UK jurisdictions, and an easy reach for someone standing at the curb. The install card included shows the exact placement.
Does this work on iPhone?
Yes. iOS supports push notifications for installed Progressive Web Apps as of iOS 16.4+. After ordering, you’ll open app.glassping.com in Safari and tap “Add to Home Screen” — that’s the install. Pings behave just like a native app from there.
How is this different from leaving a paper note?
A paper note in the window exposes your number to anyone who walks past your car — including people you’d never want to give it to. GlassPing keeps your number private, gets messages to your phone instantly, supports photos for incidents, and doesn’t fade after the first week of sun.
