To help you quickly find videos again, YouTube stores a search history for all terms you’ve searched for on YouTube. This search history is account-based and is therefore shared by any device logged in to your account. The search history can be a useful feature, but you may not want YouTube to store a list of everything you’ve searched for on YouTube. Thankfully for those of you that don’t want this feature, you can disable the setting through the in-app settings.
You can access the in-app settings by tapping your profile picture icon in the top-right corner of the app.

To open the app settings, you next need to tap “Settings”, which will be the second to last option on the list.

In the settings tap “History and privacy” to access the page with the YouTube search history settings.

In the history and privacy settings page, tap the “Pause search history” slider to pause the search history. The setting will be the fourth one down the page.

You will need to confirm that you want to disable the search history function by tapping “Pause” in the confirmation popup.

If you want to clear your YouTube search history, you can also do that from this page by tapping “Clear search history”, which will be the second option from the top. You will again need to tap through a confirmation warning.
