Your midnight queries about refinancing? Those investment worries you confided to Perplexity’s AI? According to a federal lawsuit filed March 31, 2026, those supposedly private conversations might have traveled straight to Meta and Google via hidden tracking software. A proposed class-action suit claims Perplexity AI has been surreptitiously embedding “undetectable” trackers that share users’ most sensitive AI interactions with tech giants—even when you’re browsing in “Incognito” mode.
The Tracking Scandal Unfolds
The complaint alleges these trackers download automatically when users log into Perplexity’s homepage, providing Meta and Google complete access to your AI conversations for advertising exploitation and data resale. This violates California privacy laws, according to the lawsuit. The tracking reportedly works regardless of your browser settings, making those privacy modes about as effective as a screen door on a submarine.
Real Users, Real Consequences
The lead plaintiff, identified as “John Doe” from Utah, detailed how he shared family financial information, tax obligations, investment portfolios, and financial strategies with Perplexity’s chatbot—exactly the kind of sensitive data users assume stays private between them and the AI. The lawsuit seeks class certification for all affected users, potentially encompassing anyone who trusted Perplexity with personal information while these tech giants‘ trackers allegedly operated.
Companies Circle the Wagons
- Perplexity spokesperson Jesse Dwyer stated the company hasn’t been served and cannot verify the lawsuit’s claims
- Meta responded by pointing to policies that prohibit advertisers from sending sensitive data through Facebook’s systems
- Google remained silent
These responses feel familiar—like watching politicians answer different questions than the ones asked.
Trust Issues in AI’s Wild West
This lawsuit adds to Perplexity’s growing legal troubles, including a separate Amazon suit over account access violations. The pattern suggests AI companies are moving fast and breaking things—including user trust. Your private AI conversations were supposed to be just that: private. If these allegations prove true, that fundamental assumption just got shattered.
