Chrome Exempts Google Sites from Clearing Cookies and Site Data Settings When You Quit Chrome

In Google Chrome’s “Cookies and site data” settings, accessible via the Preferences menu item or directly with chrome://settings/cookies in the address bar, you can enable the setting “Clear cookies and site data when you quit Chrome”. However, it appears that Chrome exempts Google’s own sites, such as Search and YouTube, from this setting.

For example, Chrome respects the “Clear cookies and site data when you quit Chrome” setting for apple.com but not entirely for youtube.com. In order to prevent YouTube from saving data, you have to add it to “Sites that can never use cookies”. (Note that adding YouTube to “Always clear cookies when windows are closed” is not sufficient.)

I agree with the author, they will probably put up a statement calling it a bug.
