Online status of Whatsapp is the indicator that your contact is currently online or offline. Unlike last seen capability, online status cannot be turned off by users. It is always on! Also, even if you are not listed on a person's contact list, you can still see if that person is online or not.
There are two critical facts about Whatsapp online status.
1. It is always on. You can not disable it.
2. You don't need to be listed on your contact's phone book.
These two features make Whatsapp to track your contact whenever you want to know if he/she is online or offline.
You can do this and watch your contact on Whatsapp or you can do it by some third party products.
