How do I reset the server data so everyone's data for this game is erased?

I want people to come back to this game as if they were a new player. Here is the Game Data Store Script, what should I change to make this possible?

config = game:GetService("ReplicatedStorage"):WaitForChild("GameConfig")
mod = game:GetService("ServerScriptService").GameRemoteHandler.NotifyEvent
serv = game:GetService("DataStoreService")
local Stats = serv:GetDataStore("StatsDS")
local Tools = serv:GetDataStore("ToolDS")

LoadData = function(plr,level,exp,gold,rebirths)
	-- Stats
	pcall(function()
		local GetData = Stats:GetAsync(plr.UserId)
		if GetData then
			level.Value = GetData[1]
			exp.Value = GetData[2]
			gold.Value = GetData[3]
			rebirths.Value = GetData[4]
		else
			level.Value = 1
			exp.Value = tonumber(nil)
			gold.Value = tonumber(nil)
			rebirths.Value = 1
		end
		-- Tools
		local ActualTools = {}
		local ToolStorage = require(config).ToolStorage
		if (Tools:GetAsync(plr.UserId)) then
			for _,v in pairs(Tools:GetAsync(plr.UserId)) do
				print(v)
				if ToolStorage:FindFirstChild(v) then
					table.insert(ActualTools, v)
				end
			end
			for _,v in pairs(ActualTools) do
				ToolStorage:FindFirstChild(v):Clone().Parent = plr:WaitForChild("StarterGear")
				ToolStorage:FindFirstChild(v):Clone().Parent = plr:WaitForChild("Backpack")
			end
		end
		local DataLoadBoolean = Instance.new("BoolValue")
		DataLoadBoolean.Name = "DataLoaded"
		DataLoadBoolean.Parent = plr
	end)
end

SaveData = function(plr)
	-- Stats
	pcall(function()
		local lstats = plr:FindFirstChild("leaderstats")
		if (lstats~=nil) then
			local level = lstats:FindFirstChild("Level")
			local exp = lstats:FindFirstChild("XP")
			local gold = lstats:FindFirstChild("Gold")
			local rebirths = lstats:FindFirstChild("Rebirths")
			if (level~=nil) and (exp~=nil) and (gold~=nil) and (rebirths~=nil) then
				Stats:SetAsync(plr.UserId,{level.Value,exp.Value,gold.Value,rebirths.Value})
			end
		end
		-- Tools
		local ActualTools = {}
		local SG = plr:WaitForChild("StarterGear")
		for _,v in pairs(SG:GetChildren()) do
			table.insert(ActualTools, v.Name)
		end
		if ActualTools[1] then
			Tools:SetAsync(plr.UserId,ActualTools)
			warn(plr.. "'s data has been successfully saved.")
		end
	end)
end

		end)
