I use the noaa site for the locality. Look at the weather radar for cloud cover/rain/fronts and then use one of the sun/moon rise/set apps Sean referenced (TPE) awhile back for times/angles. I have a different website of positioning during the day - https://www.gaisma.com/en/location/orlando-florida.html - it sets the general angle and the TPE gets me lined up w/ landmarks.

As to the cookie stuff - way too geeked for me.
