STEP 01
Give us an email. That's it.
Confirm the address and your QR code arrives as a high-resolution image — free, no card, in a couple of minutes.
01 Free. Private. Public-facing.
Get reached without giving out your number.
GlassPing is a QR code for the inside of your windshield — visible from outside, ready to scan. Anyone who needs to reach you sends a quick message or photo, and you get an instant ping on your phone. Your number never leaves your pocket.
Free forever
Number never visible
No app for the scanner
02 How it works
Four steps, then never think about it again.
Sign up, print, stick it inside your windshield once. After that it just sits there — visible, ready, quietly waiting for the day someone needs to reach you.
STEP 02
Print it, or have it printed.
Any printer and sticker paper works, and it goes on the inside of the glass so weather never touches it. Would rather not print it yourself? One click sends the design to Zazzle, who print and ship it — their price is shown before you order.
STEP 03
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 04
You get pinged. Instantly.
A push notification lands on your phone in seconds. Your number stays private the whole time — and on Plus you can write back without either side learning anything about the other.
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.
05 Pricing
Free to use. Plus when you want more.
Everything that makes the sticker work — the code, the pings, the photos, the private inbox — costs nothing. Plus is for people who want to reply, keep records longer, or run more than one sticker.

06 Frequently asked
Questions worth answering before you start.
Is it really free?
Yes. The QR code, your private inbox, push and email pings, inbound photos and messages — all free, permanently, with no card. GlassPing Plus ($4/month or $29/year) adds replying, longer retention, an evidence-pack PDF, quiet hours and extra stickers. Nothing about the free plan expires or degrades if you never upgrade.
What actually gets delivered?
A high-resolution PNG of your QR code, emailed as soon as you confirm your address — not a physical sticker in the post. You print it on sticker paper at home, or use the one-click Zazzle link we include to have it printed and shipped; Zazzle set that price and you'll see it before you order. The code is yours either way and never changes, so you can reprint it any time.
How durable is it on a windshield?
It goes on the inside of the glass, so weather never touches it. Printed on ordinary sticker paper it will outlast the car; ordered through the Zazzle link it comes on proper sticker stock, cut to shape. The QR contrast is tuned to stay scannable through tinted windshields, and reprinting costs you nothing because the code never changes.
Do I need to download an app?
Scanners don't — they point a camera at the code and a normal web page opens. As the owner you'll add the GlassPing web app to your home screen so push notifications work; there's no App Store download.
Is my phone number visible to anyone who scans?
No. We never share your number, email or name. Scanners see a message form and nothing else. On Plus you can reply to them, and that stays anonymous in both directions — they don't learn anything about you, and you don't learn anything about them.
What happens if I cancel Plus?
You move back to the free plan and everything keeps working. Nothing is deleted: your sticker, your code and your messages stay. Retention shortens back to 30 days, but we never cut a message's life to less than seven days from the moment you downgrade, so there's always time to save anything you need.
What if I lose access to my inbox?
Sign in at app.glassping.net with the email you signed up with — we'll send a fresh magic link. The QR code itself never changes, so you don't need to peel anything off your windshield.
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 placement guide we email shows the exact spot.
Does this work on iPhone?
Yes. iOS supports push notifications for installed Progressive Web Apps as of iOS 16.4+. After signing up you'll open app.glassping.net 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 exposes your number to everyone who walks past your car — including people you'd never want to give it to. GlassPing keeps your number private, delivers messages to your phone instantly, supports photos for incidents, and doesn't fade after a week of sun.
