Perplexity AI Sued for Sharing User Chats with Meta and Google — Even in Incognito
A federal class-action lawsuit filed on April 1, 2026 alleges that Perplexity AI secretly transmits your conversations to Meta and Google in real time via hidden tracking scripts — including when you are using Incognito mode. Here is what the lawsuit claims, how Perplexity responded, and what you should know as a user.
TL;DR
- Case filed: April 1, 2026 — Doe v. Perplexity AI Inc. (N.D. Cal., 3:26-cv-02803)
- Allegation: "undetectable" tracking scripts send full conversation content to Meta + Google in real time
- Alleged bypass: works even in Incognito mode
- Not disclosed in Perplexity's privacy policy, per the complaint
- Defendants: Perplexity AI, Meta Platforms, Google LLC (Alphabet)
- Perplexity response: "We have not been served any lawsuit that matches this description"
- Case is very early stage — class certification not yet granted
What the lawsuit says happened
The complaint was filed by a Utah man identified as John Doe who says he used Perplexity AI to research sensitive personal financial information — taxes, investments, and family finances. He believed these conversations were private.
According to the lawsuit, Perplexity embeds tracking software that activates automatically when users log in. These scripts are described as "undetectable" and allegedly transmit users' full conversation content — not just metadata — to Meta and Google as users type. The complaint specifically asserts that this happens even in Incognito mode, which many users reasonably assume provides protection from third-party tracking.
The suit names three defendants: Perplexity AI Inc. for the alleged tracking; Meta Platforms Inc. for receiving and allegedly using the data for targeted advertising; and Google LLC (Alphabet Inc.) for the same. The complaint describes Meta and Google as exploiting the data for advertising and resale to other third parties.
The legal claims
| Law cited | What it requires | Alleged violation |
|---|---|---|
| California Consumer Privacy Act (CCPA) | Explicit disclosure of data sharing with third parties; right to opt out of sale | Alleged sharing never disclosed in privacy policy |
| California Invasion of Privacy Act (CIPA) | Prohibits wiretapping and unauthorized interception of electronic communications | Real-time transmission of conversation content without consent |
| Fraud / Unfair Business Practices (CA Bus. & Prof. Code §17200) | Prohibits deceptive business practices | Representing service as private while secretly sharing data |
Perplexity's response — and what it didn't say
Perplexity spokesperson Jesse Dwyer told reporters on April 1: "We have not been served any lawsuit that matches this description so we are unable to verify its existence or claims."
There are two notable things about that statement. First, it does not deny the underlying practices described in the complaint. Companies that don't engage in the alleged behavior typically say something much more direct: "These allegations are false." Perplexity's response focused entirely on procedural grounds — not yet being served — without addressing the substance.
Second, neither Meta nor Google issued public statements on the lawsuit as of April 2.
It is worth noting that class-action lawsuits at this stage are allegations, not findings. The complaint is what plaintiffs claim happened; it has not been tested in court. Discovery — where Perplexity would be required to produce its code, logs, and internal communications — would be where the factual record gets established.
Why "Incognito bypass" is the most serious allegation
Incognito mode doesn't make users anonymous to the websites they visit — it only prevents local browser history from being saved. However, users broadly believe that Incognito provides meaningful privacy protection. That belief is why Google paid $5 billion to settle a 2024 class action over tracking Chrome users in Incognito mode.
If Perplexity's tracking scripts specifically bypass Incognito — rather than simply tracking all logged-in users — that would suggest intentional design decisions to circumvent a user's reasonable privacy expectations. That framing makes the case more serious from a regulatory standpoint and sets up a higher potential damages claim.
Context: AI privacy lawsuits are accelerating
This lawsuit is part of a broader trend. In 2025–2026, every major AI platform has faced some form of privacy scrutiny: ChatGPT conversations were found to appear in search results due to a configuration error; Google's Gemini faced questions over its Gmail integration; and multiple AI companies received inquiries from the FTC over training data sourcing.
The pattern reflects a structural tension: AI assistants derive value from personalization and context, but personalization requires data. The more data an AI system retains about users, the more valuable it becomes — and the larger the privacy risk if that data is shared, sold, or breached.
What users should do
Avoid sensitive queries on AI search tools
Until this case is resolved or Perplexity provides clearer disclosure, treat AI chat tools like you would treat a Google search: assume anything you type could be stored and potentially shared.
Review Perplexity's privacy policy directly
Check Perplexity's current privacy policy for language about third-party analytics partners and advertising. Any legitimate data sharing with Meta or Google should appear there.
Consider privacy-focused alternatives for sensitive searches
Brave Search AI and DuckDuckGo AI Chat both have explicit no-tracking policies for AI queries. For sensitive financial or medical questions, these may be preferable until this lawsuit is resolved.
Understand Incognito's actual limits
Incognito prevents local browser history. It does not prevent the website you're visiting from tracking you, nor does it prevent third-party scripts that website loads from running. The only way to block those is with a tracker blocker like uBlock Origin.

What does the Perplexity AI lawsuit allege?
The class-action lawsuit (Doe v. Perplexity AI Inc., filed April 1, 2026 in U.S. District Court, Northern District of California) alleges that Perplexity AI embedded 'undetectable' tracking scripts in its search engine code that automatically transmit users' full conversation content to Meta Platforms and Google in real time. The suit alleges this occurs even when users are browsing in Incognito mode, and that it was never disclosed in Perplexity's privacy policy.
What did Perplexity say in response to the lawsuit?
A Perplexity spokesperson stated on April 1, 2026: 'We have not been served any lawsuit that matches this description so we are unable to verify its existence or claims.' The company did not explicitly deny the underlying tracking practices described in the complaint. The lawsuit is in its earliest stage and Perplexity has not yet filed a formal legal response.
What California laws does the lawsuit cite?
The complaint cites violations of California privacy laws, primarily the California Consumer Privacy Act (CCPA), the California Invasion of Privacy Act (CIPA), and general fraud and unfair business practices statutes. The CCPA requires explicit disclosure of data sharing practices with third parties; the CIPA prohibits wiretapping and unauthorized interception of electronic communications. Sharing AI conversation content with advertisers like Meta and Google without disclosure would potentially violate all three.
Should I stop using Perplexity AI?
The lawsuit is at the earliest stage — class certification, discovery, and a potential trial are all years away. The allegations are serious but unproven. If you use Perplexity for sensitive queries (financial, medical, legal, personal), you may want to avoid sharing information you would not want Meta or Google to have, until the case is resolved or Perplexity provides clearer disclosure. If you want an AI search tool with a stronger privacy track record, Brave Search AI and DuckDuckGo AI are alternatives.
