it is Fizzer Official that the ToS exists for in case someone sues him, but the real rules are on i think this page

https://www.warzone.com/wiki/Warzone_Idle_FAQ#Cheating> Do not attempt to modify the game data, modify your system clock, or automate the game in any fashion except as provided within the game's normal UI.
which, sure, makes sense, but what is automating? Is calculating an improved recipe stats panel automating[1]? My intuition says no. What about moving the Auto-Conquer toggle box to the top of the advancements list to reduce scrolling? That's certainly a modification to the game's normal UI but I also suspect it would be alright. What about a "buy" button next to an alloy that opens the market for that alloy? You could argue that that's automation but removing the player task "scroll through list of markets to find market that has thing" doesn't change the nature of the game at all or improve performance, so I would suspect that that's also legit.
This thread is to ask about these things.
[1] it doesn't show the "techs need" stat for recipes that have not been unlocked (but which are in markets), which makes it much less useful than it should be.
