Perplexity AI Class Action Lawsuit 2026, Was Your Incognito Mode a Sham? What Users Need to Know

A federal class action lawsuit filed March 31, 2026 accuses Perplexity AI of secretly sending users’ private chat conversations to Meta and Google — including when users believed they were protected by Perplexity’s “Incognito mode.” The lawsuit names all three companies as defendants and alleges that tracking software embedded in Perplexity’s platform transmitted the full text of user chats, along with personal identifying information, to two of the world’s largest advertising companies without users’ knowledge or consent. No settlement exists yet. This is an active, early-stage case.

Where the Case Stands Right Now

• The case, Doe v. Perplexity AI, Inc. et al, was filed March 31, 2026 in the U.S. District Court for the Northern District of California. It is in its earliest stage — no class has been certified, no settlement has been proposed, and no claims process is open.
• A request to Perplexity for comment was promptly acknowledged by Jesse Dwyer, the company’s chief communications officer, who said: “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 deny the underlying tracking practices described in the complaint.
• The lawsuit names Perplexity, Meta, and Google as defendants. All three companies are expected to file motions to dismiss, which is standard at this stage.

What Is Perplexity AI and Why Does This Matter?

Perplexity AI is an AI-powered search engine that lets users ask questions and receive detailed, conversational answers — similar to ChatGPT but focused on web search. It has attracted tens of millions of users who see it as a smarter, cleaner alternative to traditional ad-supported search.

The complaint says Perplexity was valued at $20 billion in September 2025 when it raised $200 million in funding. That makes this far from a small startup. It is a major platform processing tens of millions of sensitive queries every month.

The reason this lawsuit feels different from a typical data breach case is the nature of what people share with AI chatbots. The complaint cites studies of multiple AI platforms that have found that many users specifically and intentionally turn to AI systems for issues they are reluctant to discuss with other humans, including things like relationship advice, companionship, and sexual or identity exploration. When someone types a private question into an AI chat window — especially one with an “Incognito mode” — they have a reasonable expectation that their words stay private.

What the Lawsuit Actually Claims Happened

The lawsuit’s core allegations are technical but the impact is simple: every time you typed something into Perplexity, more than just Perplexity may have been reading it.

According to the complaint, trackers are downloaded onto users’ devices the moment they log into Perplexity’s home page. The case, Doe v. Perplexity AI Inc. (3:26-cv-02803), was brought by a Utah resident who claims he shared sensitive financial and tax information with the AI chatbot, not realizing that his conversations were being relayed to advertising platforms.

The 135-page complaint alleges Perplexity embedded Meta Pixel, Google Ads, Google DoubleClick, and Meta’s Conversions API trackers directly in its code. These tools allegedly sent user conversations — including prompts, responses, email addresses, IP addresses, and device information — straight to Meta and Google for ad targeting.

The complaint describes this as more than standard website analytics. The complaint describes the ad trackers as “browser-based wiretap technology” and accuses all three companies of prioritizing profits over privacy rights.

The Incognito Mode Problem

This is the part that most users will find alarming. Perplexity markets an “Incognito mode” feature that it describes as creating anonymous threads that expire after 24 hours and won’t save to a user’s history. The lawsuit says that promise meant nothing.

The lawsuit states that Perplexity never informed its users that its Incognito mode was a sham, or that interacting with Perplexity in Incognito mode would not protect users from having the contents of their communications shared with Meta and Google.

Non-subscribed users face worse exposure, the lawsuit claims. Their initial prompts are shared with a URL that allows third parties to access the entire conversation.

What makes this especially concerning is that Incognito mode is specifically designed to create a sense of privacy — the kind of feature someone would deliberately turn on before asking something sensitive. The complaint argues that Perplexity knowingly marketed privacy protection that did not actually exist.

What Data Was Allegedly Transmitted?

According to the complaint, it was not just your search queries. The complaint alleges that the tracking technology used by Meta and Google allows the companies to harvest the user’s email address, Facebook ID, IP address, as well as information about the user’s device and browser. Once Google and Meta have that information, they can pair it with the user’s name and address and specifically identify the user.

Beyond identifying you, the lawsuit claims the trackers captured your actual words. The plaintiff says that the technology allows Google and Meta to access the full text of chats with Perplexity — both the user’s prompts and the AI’s responses.

The lawsuit also alleges that this data sharing allows Meta and Google to exploit this sensitive data for their own benefit, including targeting individuals with advertising and reselling their sensitive data to additional third parties.

What Laws Does the Lawsuit Claim Were Broken?

The 135-page complaint brings 14 counts against Perplexity, Google, and Meta, including invasion of privacy — the trackers operated without consent or adequate disclosure — federal Electronic Communications Privacy Act violations, the California Comprehensive Computer Data Access and Fraud Act, CCPA violations for inadequate disclosure of data collection and failure to provide opt-out for data sharing with ad platforms, and the California Electronic Communications Privacy Act for unauthorized interception of electronic communications.

In plain terms, the lawsuit argues that embedding advertising trackers that silently capture private conversations — and telling users they are protected by Incognito mode when they are not — crosses the line from acceptable data collection into illegal wiretapping and fraud.

The complaint also alleges that Perplexity doesn’t require users to agree to its privacy policy before using the service, and that the privacy policy isn’t even linked from the Perplexity web app — meaning users cannot consent to terms they cannot find.

Who Is Eligible to Be Part of This Lawsuit?

The lawsuit proposes two groups of affected users:

Nationwide Class — You may qualify if:

• You used Perplexity AI’s free tier (no paid Pro or Max subscription)
• You chatted with Perplexity between December 7, 2022 and February 4, 2026
• Your chat data was sent to Meta or Google during that period
• You are located anywhere in the United States

California Subclass — You may additionally qualify if:

• You meet all the nationwide class criteria above
• You were a California resident at the time you used Perplexity

Paid subscribers with Pro or Max subscriptions are excluded from both proposed classes. A footnote in the complaint notes that those agreements are subject to different terms and conditions.

What Should You Do Right Now?

Because this case is in its earliest stage, there is no claims process open and no action is required from class members today. Here is what makes sense to do now:

Step 1 — Determine whether you used Perplexity AI on a free account between December 7, 2022 and February 4, 2026.

Step 2 — Think about what you shared. If you asked Perplexity about health symptoms, financial decisions, legal questions, or personal matters during that period, you are in the core group this lawsuit is trying to protect.

Step 3 — Do not share sensitive personal information on any AI platform until you understand how that platform handles your data.

Step 4 — Monitor this case. When and if a settlement is reached, class members will receive notice and have the opportunity to file claims. No action is needed until that notice arrives.

Step 5 — If you are a California resident and want to exercise your existing rights under California privacy law, you can submit a CCPA data deletion request directly to Perplexity asking the company to disclose what data it has collected and to delete it.

Step 6 — Save this information and check back as the case develops.

Estimated time to review your eligibility: approximately 5 minutes.

Frequently Asked Questions

Do I need to do anything right now to protect my right to compensation? 

No. If you are a class member — a free-tier Perplexity user who chatted between December 7, 2022 and February 4, 2026 — you are automatically included in the proposed class. No action is needed today. If the case settles, you will receive a notice through email or mail with instructions on how to file a claim.

Is this lawsuit legitimate?

 Yes. The case is formally docketed as Doe v. Perplexity AI, Inc. et al, Case No. 3:26-cv-02803, in the U.S. District Court for the Northern District of California. It was first reported by Bloomberg on April 1, 2026, and is a real, publicly filed federal complaint spanning 135 pages.

I only used Perplexity a few times. Does that matter? 

The lawsuit does not set a minimum usage threshold. The data collection allegedly began from the moment a user landed on Perplexity’s home page, and happened regardless of whether a user paid for a subscription or used Perplexity’s Incognito mode. Even a single session during the class period could be enough to qualify.

When will I receive any payment? 

There is no payment timeline yet because no settlement has been reached. Privacy class actions of this type typically take one to three years to resolve. Once a settlement is agreed upon, the court sets a claim deadline and notifies class members.

I have a paid Pro or Max subscription — am I covered? 

No. The proposed nationwide class explicitly excludes Perplexity subscribers with paid Pro or Max subscriptions. The footnote notes that those agreements are subject to different terms and conditions. The plaintiff holds a free account and does not seek to represent paid subscribers.

Will this settlement payment affect my taxes? 

Privacy class action settlement payments are generally treated as compensation for a loss of a legal right rather than taxable income, but tax treatment varies by individual circumstances and settlement structure. Consult a tax professional once any settlement is reached.

What is Perplexity’s response? 

Perplexity’s chief communications officer Jesse Dwyer said: “We have not been served any lawsuit that matches this description so we are unable to verify its existence or claims.” The company has not confirmed or denied the specific tracking practices described in the complaint.

What if I missed the class period — can I still do something?

 If you used Perplexity after February 4, 2026, you are not part of this proposed class. However, California residents can still exercise their rights under the CCPA to request disclosure of what data Perplexity holds and demand its deletion, regardless of when they used the service.
