Your photos already remember every street you stood on. crosd reads only the where and when written into them, draws your trace, and — with mutual consent — shows where your path crossed someone else's, before you ever met.

crosd reads only the location and timestamp already written into your photos — on your phone — and turns years of them into a private map of where your life has been.

crosd.app/i/k7m2xp · expires 24hBoth of you see only the overlaps — the square you both stood in, and when. Never each other's full maps, never the photos.
× 2 crossings · 1 near missThe whole point of crosd is a secret shared by exactly two people. The design makes anything else impossible.
The images are never opened, uploaded, or shown to anyone — crosd only reads the coordinates and dates your camera already saved into them.
Before anything leaves your phone, every place-time becomes a one-way code. The cloud compares codes; it never sees coordinates.
Nothing is compared until the other person accepts your invite. Decline, and no one is told anything more than that.
Neither side ever sees the other's map — just the moments you were both in the same place. Delete your trace and it's gone from the cloud too.
The same café, the same platform, the same room. The closest — and the rarest.
The same block at the same time. The default — close enough to have passed each other.
The same neighbourhood, the same festival, the same shore. The widest net.
No — never. Your photos are not opened, uploaded, or analysed as images. crosd reads only the location and timestamp metadata your camera already wrote into them, entirely on your phone.
Only the crossings: the place-square you were both in, and when. They never see your full map, your photos, or anywhere you went alone — and you never see theirs.
Nothing is compared and nothing is revealed. The sender only learns that you declined — invite links also work exactly once and expire after 24 hours on their own.
Yes. Mark any place hidden with a radius around it and every photo taken there is excluded before anything is ever compared — the other side can't tell something was hidden.
As far as your photo library does. If your oldest geotagged photo is from 2009, your trace starts in 2009 — and so do your possible crossings.
One tap removes your synced trace from the cloud; deleting your account removes everything else with it. Delete means delete.
