A U.S. appeals court has revived a class-action lawsuit against Google, requiring the tech giant to face allegations that it collected personal information from Chrome browser users without their consent. The lawsuit claims that Google continued to gather data even when users chose not to synchronize their browsers with Google accounts. This decision overturns a previous ruling by Judge Gonzalez Rogers, which had granted summary judgment in favor of Google. The case involves Chrome users since July 27, 2016, and marks a significant legal challenge for Google, which has faced similar privacy lawsuits in the past.
