How are sunrise, sunset and the golden hour worked out?
With NOAA's formulas, based on Jean Meeus's astronomical algorithms, checked against NREL's reference algorithm. Sunrise and sunset are when the top of the disc touches the horizon, refraction included. The golden hour runs from +6° to −4° of sun elevation, then the blue hour down to −6°. Each calculation is explained with its sources in the app: Settings, then "Calculations and sources".
Why does the time differ from another app?
Golden hour definitions vary between sources by a degree or two. And no app sees your real horizon: a mountain, buildings or the weather can hide the sun before the calculated time.
Why does Sunory ask for my location?
The sun's course depends on where you stand. An approximate location is enough: a few kilometres move the sun by hundredths of a degree. Your location is only read while you use the app and is not stored. It only leaves your phone for the sun map, which asks Mapbox for the images of the area around it. Access can be withdrawn in your phone's Settings.
Why does the 3D view ask for the camera?
To lay the sun's course over what you see. The image is only displayed, while the 3D view is open: it is neither recorded nor sent, and the microphone is never used. Access can be withdrawn in your phone's Settings. Never look directly at the sun, not even through the camera.
Near the poles
During the midnight sun or the polar night there is no sunrise or sunset that day: the app says so. Beyond 72° of latitude, the calculations lose precision.
