We built WAU because we wanted to see where we'd been. After years of travelling there was still no simple way to look at the shape of it, so we made one.
Every part of it comes out of real trips — the fog that clears along your route, the statistics that tell you how much of the world you have actually crossed, the offline QR codes that work in a forest with no signal because that is where we needed them.
Your tracks, fog, places and photos stay on your phone. There is no account to make and nothing to sync, which also means there is nobody paying us for your data. That is the part donations cover.
