This small snippets allows you to track a users WhatsApp behavior exploiting the WhatsApp web implementation. It monitors the users online-offline activity. At the moment it is only possible to monitor one user at the same time. The collected material is stored in a CSV file on your tracking machine.

Code is still under developement and needs a lot improvement. It is meant as a personal PoC, but maybe some of will find it useful. If you have any questions, sugesstions or see bugs just let me know.

• Smartphone and phone number where WhatsApp is installed and registred
• A browser on a Windows/Linux/Mac machine which is connected to the SmartPhone using WhatsApp web (tested on Chrome)
• The Smartphone and tracking machine (WhatsApp web) needs to be online 24/7 to ensure that a full time monitoring of the user is achived
• Python 3 installed on you tracking machine
• RECOMMENDED: It is recommended to use a dedicated phone number which only uses WhatsApp for tracking purpose. If you use your private WhatsApp installation it may interfere the tracking because there are some DOM struggles I am fighting with at the moment. It does not mean that it will not work with multiple chats in WhatsApp web. It just means I tested it in an environment where only one chat is available in WhatsApp web
