Manage your data
YouTube
To allow you to easily find videos you watched recently, YouTube remembers your viewing history. You can delete your viewing history either by removing individual videos or clearing all videos in your history. You can also pause your viewing history to stop YouTube remembering the videos you’ve watched.
Similarly YouTube saves your search history so you can remember what you’ve searched for. If you’d like to delete your search history, you have the option to remove individual videos, clear your whole history, or pause your history.
You can also control who can see your videos on YouTube by choosing between public, unlisted or private in your videos’ settings.
It’s good to know that YouTube offers ways to control your history. Read the next topic: Sharing settings in Google Docs
