Hello friends whatsapp and Facebook are the most popular website or apps in the world in the world many people have make the id on whatsapp and facebook it is not unsafe .Haan if we use it right way then there is not any harm.
I am using it from 2, 3 Years.Nothing had happend with me on the whatsapp .I am enjoying.
One thing we should do on our whatsapp app is to lock with password so that no body can see your messages and use it for wrong.
I love this Thanks to company for making this app for us.
