I am trying to make a datastore jail, I have jail tool but it doesnt save. How do I do this?

I am trying to make a datastore jail, I have the jail tool that sends the player to jail and after 30 seconds it sends them out of the jail (unjails them) but I quickly noticed people started to leave the game and rejoin. How do I fix this/make it in a datastore.

tool = script.Parent

function touch(hit)
h = hit.Parent
g = h:findFirstChild("Humanoid")
if (g ~= nil) then
h:MoveTo(game.workspace.Jail.Jail.Position)
wait(30)
h:MoveTo(game.workspace.Jail.Unjail.Position)
end end

function sel()
tool.Handle.Touched:connect(touch)
end

tool.Equipped:connect(sel)

All you have to do is put a BindableEvent "JailEvent" in ServerStorage and this should work

dss = game:GetService("DataStoreService")
jailData = dss:GetDataStore("Jail")
jailTimes = {} 

function jail(player,t)
	if player and t and not jailTimes[player] then
		--records time entered jail and sentence length
		jailTimes[player] = {t,tick()}
		local char = player.Character or player.CharacterAdded:wait()
		wait(1)
	    print(player.Name .. " jailed for " .. t .. " seconds")
	    char:MoveTo(workspace.Jail.Jail.Position)
	    wait(t)
	    jailTimes[player] = nil
	    if player.Parent==game.Players then
			--removes jail data, only if still in jail
			--(jailTimes also implies whether someone is in jail)
	        print(player.Name .. " completed his sentence")
	        char:MoveTo(workspace.Jail.Unjail.Position)
			jailData:SetAsync(tostring(player.UserId),0)
	    end
	end
end

game.Players.PlayerRemoving:connect(function(player)
    local times = jailTimes[player]
    if times then
		--subtracts time jailed from sentence length for remainder
		--will be jailed again
        local remaining = math.floor( times[1] - (tick() - times[2]) )
        print(player.Name .. " left the game during jail. " .. remaining .. " seconds remain.")
        jailData:SetAsync(tostring(player.UserId),remaining)
    end
end)

game.Players.PlayerAdded:connect(function(player)
	--jails player if has remaining time
    local jailTime = jailData:GetAsync(tostring(player.UserId)) or 0
    if jailTime > 0 then
        jail(player,jailTime)
    end
end)

--any script can jail any player with this
game.ServerStorage:WaitForChild('JailEvent').Event:connect(function(player,t)
    jail(player,t)
end)

Tool

tool = script.Parent
db = false

function touch(hit)
	if db then return end
	db=true
	local char = hit.Parent
	local hum = char:FindFirstChild('Humanoid')
	if hum  then
		local player = game.Players:GetPlayerFromCharacter(char)
		if player then
			game.ServerStorage.JailEvent:Fire(player,30)
			wait(3)
		end
	end
	db=false
end

function sel()
tool.Handle.Touched:connect(touch)
end

tool.Equipped:connect(sel)
