Enter AR
Point your phone at the world and the drops around you appear where they actually are.
Camera
The live view the pins are drawn over. Nothing is recorded or uploaded.
Location
Works out which drops are within 75 m of you, and where to place them.
Motion & compass
Tells us which way you're facing so a pin stays put when you turn.
Nothing from your camera leaves the device. Your position is only used to work out which drops are in range.
