Who can see my restaurant's WhatsApp Status and can I hide it from some people?

By default all your saved contacts see your Status. To hide it from some people, open the Status tab, More, Status Privacy and choose My contacts except or Only share with.

• Options: My contacts, My contacts except, or Only share with.
• People whose numbers are not saved in your phone's address book cannot see your Status.
• Mentions and groups: a mentioned person or group can see it, and a Status posted to a group is visible to all its members.
• Changes to privacy settings do not affect Statuses you already shared.
