in Golf category, some players use wind tracker that shows us wind seeds.

I want to use it, but I don't know how to install it.

Wind Tracker is a website made by Vncz.

In order to use it you simply input the winds as they show up in game. In order to get seeds you should have goldfish enabled (but not chaining yet) once you get your first seed (which is usually on hole 7) you will want to reset and turn on wind chaining. If you have a deep run afterwards you may need to press custom advance once or twice if it reads 0 possibilities (enter first 3 winds before you do this) here is the link: windtracker

Thanks

but I don't know using this tool is allowed.

how is it really?

It's a manual input; it's also technically already available information if you had encyclopedic knowledge of wind seeds in the game. I don't see any problem with it really. Also thought it was quite cool to be able to plan for upcoming holes.
