TagTrek
Scan to return — never lose your belongings again
A privacy-first smart QR tag system for luggage, keys, and personal items. Attach a dynamic QR tag to anything you own; if it's lost, whoever finds it scans the tag to reach you — no app or account required for the finder. Three visibility modes (Normal, Traveling, Lost), anonymous in-app messaging, and city-level location only with no GPS tracking.
Visit WebsiteDynamic QR Codes
Each tag links to a profile you control. Print it once and stick it on anything — the QR never changes, but what it shows always does.
Three Visibility Modes
Switch a tag between Normal, Traveling, and Lost — each surfacing different contact details and custom messages so finders see exactly what you choose.
Privacy-First by Design
No GPS tracking — owners set city-level location manually. IP addresses are stored only as SHA-256 hashes, and every table is locked down with row-level security.
Anonymous Messaging
Finders start a conversation without revealing their identity or installing anything. Chat with them in-app to arrange the return.
No App Required for Finders
A finder simply scans the tag, sees the info you've chosen to share, and contacts you — straight from a fast Astro static web page.
Real-Time Scan Alerts
Get an Expo push notification the moment one of your items is scanned, with Cloudflare Turnstile and rate limiting guarding every public endpoint.
