You can hide or delete the history of a direct message conversation.
- Hide conversation—Removes your copy of a conversation from your Hangouts Chat view. It doesn't remove the conversation from other participants views.
- Delete conversation—Permanently deletes your copy of a conversation's history. It doesn't delete the conversation from other participants history.
Direct message conversations you delete in Hangouts Chat are also deleted in classic Hangouts, and the other way around. Conversations you previously deleted in classic Hangouts, before conversations could be deleted in Chat, are not deleted in Chat.
Hide a direct message conversation
You can hide a direct message conversation from your view, including group conversations with 2 or more people.
