'This week the Verge reported:
If you ask Chrome to delete all cookies and site data whenever you
quit the browser, it's reasonable to expect that this policy applies
to all websites. Recently, though, a bug in the browser meant data
wasn't being removed for two sites in particular: Google and YouTube.
This problem was first documented by iOS developer Jeff Johnson on his
blog. Johnson found that in Chrome version 86.0.4240.75, "local
storage" data for Google.com
stuck around even after
restarting the browser. We've been able to replicate similar
behavior... The Register notes that Chrome's behavior could allow
Google to stash cookie-style data as site data, allowing it to track
users even when they think they're being careful by deleting their
cookie and site data every time they close the browser.
In a statement, Google said it was aware of the issue and was working
on a fix... At least one of the affected sites, YouTube, appears to
have already been fixed. After we upgraded the Chrome browser to
version 86.0.4240.111, YouTube's local storage data seems to
successfully purge after a restart, although the data from Google.com
still sticks around.'
