The WhatsApp tracking lets you access all the chats or messages that your kid is exchanging with his/her friends. Not only this, the additional information can also be accessed so that you can know the name and contact of the sender and every other detail. This also lets you know the media exchange such as pictures or selfies shared by your kid at the exact time. So in other words, you can do real time monitoring of your kids' activities on WhatsApp without letting them know and also check every detail of the sender.
