Profile customization includes adding a photo, name, and About text, which appear in your contact details. You can manage notification preferences, data usage, and backup settings from the app’s Settings menu.
Privacy and Security Settings
WhatsApp offers several privacy controls that let users manage who can see their profile information and interact with them. These settings help users balance convenience with confidentiality.
Profile Visibility
Users can choose who sees their profile photo, about text, and status updates, with options such as Everyone, My Contacts, or Nobody.
Encryption and Data Protection
End-to-end encryption ensures that only the sender and recipients can read or listen to messages and calls. Security codes can be verified in chat settings for additional assurance.
