Perplexity AI Sued for Allegedly Sharing User Conversations With Meta and Google Through Hidden Trackers

Perplexity AI has been hit with a proposed class-action lawsuit in federal court in San Francisco alleging that trackers are automatically downloaded onto users' devices upon login, giving Meta and Google full access to their AI conversations in violation of California privacy laws. The suit claims the data sharing occurs even in Perplexity's “Incognito” mode, allowing Meta and Google to use the sensitive information for ad targeting and potentially resell it to additional third parties. Perplexity said it has not been served any lawsuit matching the description and was unable to verify its existence, while Meta pointed to its own rules prohibiting advertisers from sending it sensitive data, and Google did not respond to comment requests.
