Where these go

Photographs are re-encoded on this device before they are stored, which strips the location and camera data a phone puts in a file. They stay in this browser. Nothing here uploads them.

No photographs yet.

The most useful one is taken from where you actually sit, held level, pointing at whatever is bothering you.
