How to Clear Chat History on Facebook
Facebook allows you to keep in touch with friends through a variety of methods: posting on their Facebook page, sending them a message or chatting with them through an instant messaging program. As you chat, Facebook records your chat history in a log. This log keeps a record of every conversation you have for when you need to reference something discussed earlier. However, if having Facebook keep a record of your private conversations is unnerving, you can delete your chat history with a few easy steps.
Sign in to your Facebook account.
Click the name of a friend, located on the right side of the screen, whose chat history you want to delete. A chat window between you and that friend opens.
Click the gear-shaped icon in the upper right corner of the chat window to open the "Actions" menu, then click "See Full Conversation."
Click the "Actions" drop-down menu and choose "Delete Messages."
Click "Delete All," followed by "Delete Conversation" to completely clear your chat history with that contact.
Tips & Warnings
- When you delete your chat history, it is permanently deleted, so make sure to copy any important information before deleting it, if need be.
