U.S. appeals court revives Google privacy class action over Chrome data collection

A U.S. appeals court said Google must face a revived lawsuit by Google Chrome users over privacy issues.

A U.S. appeals court said Google must face a revived lawsuit by Google Chrome users who said the company collected their personal information without permission, after they chose not to synchronise their browsers with their Google accounts.

The 9th U.S. Circuit Court of Appeals in San Francisco said the lower court judge who dismissed the proposed class action should have assessed whether reasonable Chrome users consented to letting Google collect their data when they browsed online.

Tuesday's 3-0 decision followed Google's agreement last year to destroy billions of records to settle a lawsuit claiming the Alphabet unit tracked people who thought they were browsing privately, including in Chrome's "Incognito" mode.

Google said in a statement: "We disagree with this ruling and are confident the facts of the case are on our side. Chrome Sync helps people use Chrome seamlessly across their different devices and has clear privacy controls."

Matthew Wessler, a lawyer for the plaintiffs, said he was pleased with Tuesday's decision and looked forward to a trial.

The proposed class covers Chrome users since July 27, 2016 who did not sync their browsers with their Google accounts.
