Wings for worried parentsIf your child gets lost, one scan brings them home.
LostMySon is a tiny winged badge for backpacks and belt loops. Anyone who finds your child taps it with a phone — or scans the QR code — and lands on a calm safety page that can call you in one tap.
No subscription. No app to install. Ships to the US and internationally.
How it works
Three steps, five minutes, and then it just sits there quietly — ready if you ever need it.
1. Buy the keychain
Pick your badge, tell us where to ship it. Free safety page included for every tag.
2. Register your child
Tap your new tag, create a profile, and choose exactly which details a stranger may see.
3. A scan reunites you
Anyone who finds your child taps or scans the badge and can call you instantly — no app needed.
What the person who finds your child sees
No login, no confusion, no tiny text. Three big buttons and a calm message written for someone who is nervous and holding a phone in one hand.
- Call the parent, straight from the page
- Call the right local emergency number — 911, 112, 190 and more
- Share their exact location with you by text or email

Your child's privacy comes first
You choose every field
Each detail has its own switch. Show a first name and one phone number, or nothing at all — it's your call.
Unguessable links
Every tag has a long random code. Safety pages are never listed, never indexed by search engines, and always served over HTTPS.
Delete anytime
Deactivate a tag with one tap, or delete a profile permanently. When it's gone, it's really gone.
