WhatsApp says that once you enable disappearing messages in any chat, new messages will automatically disappear after 7 days. However, this does not have any impact on the existing messages in the chat, that is, before you enable the disappearing messages option. If it is a chat between you and a friend, either party can turn on or turn off disappearing messages.
This option will be available in WhatsApp -> Chat -> Contact Name -> Disappearing Messages.
