Perplexity AI Hit with Class-Action Lawsuit: Allegedly Shared User Data with Meta and Google Even in Incognito Mode

Bloomberg·high signal

Bloomberg reports Perplexity AI was sued in federal court in San Francisco after a complaint alleged trackers are downloaded to user devices upon login, giving Meta and Google full access to conversations — even in Perplexity's Incognito mode. The plaintiff claims this 'backdoor access' lets the companies exploit sensitive data for targeted advertising and resale to third parties. Perplexity denies the allegations, but this comes alongside Amazon securing a court order blocking Perplexity's Comet browser from accessing Amazon's services.
