Did We Cross?

Find out if your paths ever crossed — before you even met.

You and a friend compare the hidden time-and-place notes in your own photo galleries. If you were ever in the same place at the same hour, you'll both find out — and nobody else ever could.

How it works

Your phone reads only the time & place inside your own photos. Pictures are never uploaded, copied, or even opened.

Each moment becomes an anonymous puzzle piece. A scrambled code, locked with a key only you and your friend hold. It cannot be turned back into a place or a time.

Your phones swap puzzle pieces directly and compare them locally. If two pieces fit — you crossed paths. Each phone shows the moment from its own gallery.

Private by design

🖼️

We do NOT store your photos or locations. Everything is processed in your phone's memory and forgotten when you close the app.

📱

All calculations happen on your phone. The scanning, the scrambling, and the matching never leave your device.

🧩

Only irreversible, anonymous puzzle pieces are exchanged. Nobody — including us — can unscramble them. Not even with unlimited computing power, without your private key.

🕊️

Our server has no database and forgets everything instantly. It is a carrier pigeon: it passes the sealed envelope between you two, then forgets it the same millisecond. No logs, no storage.
