Perplexity AI Sued for Secretly Sharing User Conversations with Meta and Google
By Connie · April 2, 2026 · 7 min read
A Utah man filed a federal class-action lawsuit on April 1, 2026, accusing Perplexity AI of embedding undetectable tracking software that automatically shares user conversations — including sensitive financial and tax information — with Meta and Google. The tracking allegedly operates even when users activate Perplexity's "Incognito" mode. Perplexity denies the claims. Meta and Google are also named as co-defendants. Case: Doe v. Perplexity AI Inc., 3:26-cv-02803.
What the Lawsuit Claims
The complaint was filed by a Utah man identified as "John Doe" in federal court in San Francisco on April 1, 2026. It accuses Perplexity AI of violating California privacy laws by secretly transmitting user conversations to Meta and Google through tracking software embedded in the search engine's code.
According to the complaint, when users log into Perplexity's homepage, tracking tools are automatically downloaded onto their devices — before any conversation takes place. Once installed, these trackers allegedly grant Meta and Google full access to the conversations between users and Perplexity's AI search engine, allowing the tech giants to exploit this sensitive data for targeted advertising and for resale to third parties.
The plaintiff says he shared highly sensitive information with Perplexity, including details about his family's finances, tax obligations, and investment strategies — believing the conversations were private. The suit also specifically alleges that Perplexity's "Incognito" mode provides no actual privacy protection, as tracking continues even when the mode is activated.
Perplexity's Response — and Meta's
Perplexity AI strongly denied the allegations. Spokesperson Jesse Dwyer stated:
Meta's spokesperson pointed to Facebook's help pages, which state it is against the company's rules for advertisers to send sensitive user information, and noted Meta had not been served with a matching lawsuit. Google representatives did not immediately respond to requests for comment, according to Bloomberg's reporting.
If served, Perplexity, Meta, and Google will file responses with the court. Class certification — deciding whether this becomes a full class action representing all affected users — is typically the first major hurdle. Similar data privacy cases against tech companies have settled for tens or hundreds of millions of dollars, or been dismissed at early stages.

The data-sharing lawsuit is not Perplexity's first legal challenge in 2026. The company has accumulated a pattern of legal and reputational friction:
Multiple news publishers sue Perplexity over content scraping and reproducing articles without permission or attribution. The New York Times, News Corp, and others join the legal wave.
Amazon files a separate lawsuit against Perplexity over its 'agentic shopping' feature, alleging unauthorized access to customer accounts and data.
Class-action filed: Doe v. Perplexity AI Inc. — alleges undetectable tracking software shares conversations with Meta and Google, even in Incognito mode.
The accumulation of lawsuits — from publishers, from Amazon, and now from users — suggests structural tensions in Perplexity's business model that go beyond individual incidents.
The Broader AI Privacy Risk Landscape
The Perplexity lawsuit reflects a broader problem in AI products: most users have no visibility into what happens to their conversations after they send them. Unlike traditional web browsing, where network inspection tools can reveal tracking, AI conversations feel more intimate — users share things with chatbots they might not type into a search box.
What this means for AI users
The safest assumption when using any AI product is that your conversations could be seen — either for model training, for ads targeting, or through legal processes. For genuinely sensitive information (finances, health, legal matters), the prudent approach is to avoid sharing specific identifying details with any AI service until privacy protections are clearer.
The Perplexity case, if the allegations hold up, would be significant because it involves real-time sharing of conversation data with ad networks — a model closer to how social media platforms monetize data than how standalone AI products have positioned themselves.

(3:26-cv-02803), filed April 1, 2026 in federal court in San Francisco, alleges that Perplexity AI embeds undetectable tracking software in its search engine that automatically transmits user conversations to Meta and Google.
