Bike returned anonymously. Yours, always.
Weatherproof, tamper-visible sticker for bikes, e-bikes and helmets. One tap and the finder reaches you — without your address, name or phone ever being exposed.
Most 'stolen' bikes are abandoned bikes.
A bike gets left at a rack, dumped in a hedge, picked up by a good samaritan. Without the sticker, nobody knows whose it is. With it, the bike is home the same day.
Left at a rack overnight
Council or security taps the tag before removing it. You get a push notification with the address and can pick it up before it's impounded.
Found abandoned in a park
A jogger notices the same bike day after day. One tap — anonymous chat opens. You confirm it's yours, they mark the location.
Kid's bike out of sight
If a neighbor's kid takes the wrong bike home, one tap on the seat post fixes it in a minute — with zero neighborhood drama.
Anyone who wants to help can. Nobody who shouldn't reach you ever will.
Three steps. Sixty seconds.
You activate once. From that moment on, every scan is an anonymous, private conversation between you and the finder.
Stick it or attach it
Peel-and-stick, or clip on. No batteries, no wiring. Every tag is unique and preloaded — you just claim it.
Someone taps
Any NFC-capable phone opens your contact page instantly. The finder needs no account, no app, no sign-up.
You're notified
Instant push + email with the scan location. Reply through anonymous chat. Your name and number are never shown.
You decide what they see. Always.
FoundSOS is built as a safety layer, not a broadcast channel. Every setting below is yours to toggle at any time.
Anonymous chat
Talk without revealing your number. Ever. Chats live on the encrypted FoundSOS relay, never on your phone bill.
You choose the channels
Show chat only, or add phone, WhatsApp, or a contact form. Your call, per tag.
Instant push + email alerts
Know the moment someone taps your tag or sends a message. No missed scans, no delays.
6-hour secure sessions
A scan opens a 6-hour contact window, then expires. No permanent link between you and the finder.
Block anytime
One switch disables chat if someone misuses it. Silence, instantly. You keep the tag and the notifications.
Optional live location
The finder can share a live map pin — useful if a bike, car or bag has been moved. Optional, revocable, never automatic.

Real returns, quietly.
My daughter's bike was found by a neighbor. He tapped the tag and we chatted anonymously — I never had to give my number.
MM · MunichFound my e-bike abandoned two streets away. Council would've fined me €80 to reclaim it.
AA · AmsterdamWeatherproof — one Berlin winter later, the sticker is unchanged.
