Perplexity AI Privacy Policy

This document explains what data Perplexity AI collects about you—including your prompts, browsing history if you use Comet, and health data if you use health-related services—and how that data may be used, including to train AI models. It also discloses that your data may be shared with third parties for advertising measurement and that those third parties may track you across other websites over time. Perplexity AI does not use your email content to train AI models, and children under 16 are not knowingly collected from without parental consent.

This privacy policy establishes the terms under which Perplexity AI collects, uses, shares, and transfers personal data from users of its services. It sets out that Perplexity AI processes user-submitted content—including prompts, queries, uploads, and AI-generated outputs—and uses that data to improve or create services and AI models, while expressly prohibiting the use of email content for AI training. The policy imposes a data collection floor of age 16 (with parental consent as the exception), restricts Google account data use to the Google API Services User Data Policy's Limited Use requirements, and establishes that the Data Privacy Framework Principles govern over the policy in any conflict. Cross-border transfers are effected by the act of data submission, and users are informed that incognito mode does not prevent tracking by Perplexity AI or third parties.

If you use Perplexity AI's services, your prompts, queries, uploads, and the outputs generated for you are collected and may be used to improve AI models. If you use Comet with a synced account, your browsing history is also recorded depending on your settings—users can review and adjust those settings to limit this collection. Submitting any personal data constitutes agreement to its transfer, storage, and processing in the United States or other countries. If you use health-related services, your health data may be shared with service providers, connected apps, and third-party AI models. Incognito mode does not prevent Perplexity AI or third parties from tracking you.
