Facebook, who owns WhatsApp announced that it is adding a setting in WhatsApp that allows users to set who, if anyone, can add them to a group.
1.In WhatsApp, tap Settings.
2. Now tap Accounts.
3. Now tap Privacy.
4. Tap the menu that says Groups. This will take you to the Group’s privacy screen that gives you three settings. If you dont yet have the Group option here try to update your WhatsApp to the latest version.
5. Select either Everyone, My contacts, or Nobody. Tap Done and the settings will be saved.
What do the three options mean ? :-
Everyone: this setting essentially keeps things as they are now. Anyone on WhatsApp can add you to a group no matter if you want to be in that group or not. Basically, this is zero privacy.
My Contacts: this setting gives anyone whose number who have saved in your phone’s address book the ability to add you to a group. This is mid-range privacy as only known people can add you to a group.
Nobody: This is the option most people will want to use. Choosing this setting means no one will be able to add you to a group automatically.
Note :- The new group privacy feature has just started rolling out globally for all users. If you don’t see it right now, you should be able to soon.
