YouTube maintains a record of videos that you watch and this becomes your YouTube Watch History. Similarly, YouTube keeps a record of Search terms that you type in the search bar and this becomes your YouTube Search History.
While both Watch and Search history helps YouTube in bringing up videos that align with your taste and interests, it also allows others that have access to your device to see what you have been watching on YouTube.
Hence, YouTube provides the option to protect your privacy by clearing your YouTube Watch and Search History on iPhone and also the option to clear YouTube history from other devices that gets linked to your Google Account.
