eecre·il y a 3 ans·discussAgreed and I think people underestimate the amount of metadata the WhatsApp servers see. It includes:- all numbers in every user's contact list- the membership of every group- the sender and recipient of every message- when every message was sent, received, and viewed or played- the dates and times that every user has been present- the type of every message sent (text, sticker, video, voice recording, poll, etc.)- the size of every message sent (to the nearest 16 bytes)- the date, time and duration of all calls made between usersAnd probably other metadata too. Basically everything except for the message content.The client also uploads crash dumps (along with a copy of the log output), and periodically sends usage statistics too.
