### Comment:
Well but if the code isn’t freely available (whatsapp is closed source right?) they might have a backdoor. Still they can probably leverage metadata without breaking the encryption. I bet a machine learning program can figure out who is your gf, who are your friends, who is your mom, who is your pusher, etc.., just by looking at message frequency, size, and similar stuff.

It’s end to end encrypted and the people that made Signal implemented their protocol for WhatsApp. 


### END.
