They've yet to reply me this month. But for last two months, they sent a excel sheet which has your IP address along with the data downloaded from ip address. Problem is, it showed usage even when I know for a fact that my PC and
router were switched off at that time.
This month, my usage is 245GB according to them whereas glasswire shows 101GB usage and in that too only 76GB was download and rest was upload. I downloaded a couple of games in steam and this would account perfectly with 76GB where as 245GB is extreme
