You shall not download any content unless you see a 'download' or similar link displayed by YouTube on the Service for that content.

Here's what YouTube's TOS states specifically: However, downloading videos is legal for personal use or under the fair use provision in most countries. YouTube specifies in their Terms of Service that you shouldn't download content by any other means than their download-button. YouTube was also fined $136 million for collecting personal data without consent. They've previously faced lawsuits in the UK for running highly targeted ads to 'influence vulnerable young minds'. YouTube has a spotty track record when it comes to privacy. When you watch a YouTube video, both the owner and YouTube can access information regarding what parts of the video you watched, on what device you watched it, and tie this information to your account if you're logged in. For privacy protection, you may want to download a YouTube video rather than watching it.In case you don't have access to YouTube Red, downloading videos is one way to avoid interruptions during video playback due to advertisements.

This way, you don't have to pay for an expensive subscription for a file hosting or file transfer service such as WeTransfer, Dropbox, Google Drive, etc.

When traveling, you may encounter low-bandwidth networks or no Internet connection at all.By saving a backup of the video locally, you ensure that you'll always have access.
