WhatsApp Tracker is a product based on the WhatsApp Web Protocol to track online events:
Whatsapp sends your online status to any person, even those who are not in your contact list and there is no way to disable it.
My goal is to make proof-of-concept show how this can be abused and that WhatsApp will add an option to hide your online status.
