FAQ

I installed Solar and launched it, but it doesn't show up!

Solar lives in your system tray which is located on the right side of your taskbar. Sometimes, you'll have to click the little up arrow to show Solar and your other system tray apps. If this is the case, you can drag it down to have it stay outside of the arrow box.

Solar isn't switching my theme at sunset!

You probabaly haven't set your location yet right click on Solar's icon in the system tray and click Set location... (it's bolded until you set it). Then get the coordinates of your location (the nearest city works fine too!) and paste them into the text box.

What does Solar use my location for?

First and foremost, your location data never leaves your computer and Solar does not collect any kind of analytics or data. Solar only uses your location to calculate when sunset and sunrise is, because they change time of day based on where you are physically on Earth.

I found a bug!

Thanks for making Solar a better app! Create a new issue describing the problem and I'll get working on a fix! If you know how to write a WPF app in C#, then you can also submit a pull request if you prefer.
