Lawsuit Claims Perplexity's Incognito Mode Fails to Protect User Privacy

Perplexity's AI search engine, designed to engage users in deep chat sessions, is under fire for allegedly sharing vast amounts of sensitive user data with tech giants Google and Meta without consent. A lawsuit claims that both subscribed and non-subscribed users' chats, including personally identifiable information (PII), are shared, even when using Perplexity's 'Incognito Mode,' which is described as ineffective. The complaint, filed by an anonymous user, John Doe, accuses the companies of prioritizing ad revenue over privacy, likening ad trackers to 'browser-based wiretap technology.' Users reportedly share sensitive financial and health information with Perplexity, only to have it potentially exploited for targeted advertising.

The lawsuit highlights the use of invasive ad trackers such as Facebook Meta Pixel and Google Ads, which allegedly operate surreptitiously to exploit user data. It also points out that Perplexity's privacy policy is not easily accessible, and the company fails to inform users about the disclosure of their data. The proposed class action spans three years and seeks substantial fines and damages for the alleged privacy violations.

Doe's complaint emphasizes the lack of transparency and accountability from Perplexity, Google, and Meta, accusing them of infringing their own privacy policies. The lawsuit seeks injunctive relief to prevent further data sharing and demands restitution for users. Google responded by stating that businesses are responsible for managing the data they collect, while Perplexity and Meta have not commented.

The case underscores growing concerns about privacy in AI tools and the potential misuse of sensitive information. Users are often unaware of the extent to which their data is shared, leading to calls for stricter enforcement of privacy policies and greater transparency from tech companies.
