Vanish mode is a feature on Instagram that allows users to send self-destructing messages, photos, videos, and other content in a chat that disappears from the thread once the chat is exited. When vanish mode is enabled, users can send messages that automatically disappear after a user leaves the chat or turns off vanish mode. This feature is useful for people who want to have private conversations that they dont want to be saved on their device or servers, ensuring maximum privacy and security. Vanish mode is shared, meaning it is turned on for both parties in an Instagram chat when you enable it, and the recipient is notified of the same. It is only available for users who you follow on Instagram or have already connected with in the past. When you turn vanish mode on or off, the other person in the chat will be notified.
