Google still tracks users browsing through incognito mode in Chrome, according to a class action lawsuit.
The legal filing in the US is seeking at least US$5,000 (AU$7,236) per user or US$5 billion (AU$7.2 billion) for violation of state privacy and federal wiretapping laws.
The case argues that Google is intentionally misleading customers by suggesting incognito mode in Chrome allows private web browsing.
"Google tracks and collects consumer browsing history and other web activity data no matter what safeguards consumers undertake to protect their data privacy," reads the lawsuit.
A Google spokesperson told Yahoo Finance that the company would defend itself.
"As we clearly state each time you open a new incognito tab, websites might be able to collect information about your browsing activity during your session," said the spokesperson.
“We strongly dispute these claims and we will defend ourselves vigorously against them.”
It was only last year when Google closed a loophole in Chrome that allowed third party websites to check whether a user was in incognito mode.
