Before installing this software, you may first read the following DISCLAIMER from its project page:

This project does not attempt to reverse engineer the WhatsApp API or attempt to reimplement any part of the WhatsApp client. Any communication between the user and WhatsApp servers is handled by WhatsApp Web itself; this is just a native wrapper for WhatsApp Web, more akin to a browser than any WhatsApp software.
