“WhatsApp” is an instant messaging application developed by Facebook and uses end-to-end encryption. WhatsApp can be used on Android and iOS smartphones, and on Microsoft Windows, Mac OS, and GNU / Linux computers after registering with a mobile phone number. “WhatsApp” provides a number of security and privacy options, including protecting access to the application with a password.

From this menu also, the user can disable “Read receipts” in conversations with individuals, and if read receipts are disabled, the user will not be able to see read receipts from other parties in the conversation.
