The policy states that user queries and received responses may be used to train and improve Perplexity's AI models, with an opt-out available through privacy settings or by emailing privacy@perplexity.ai. The default position is that this use applies unless the user actively opts out.

This provision establishes an opt-out default for use of personal interaction data in AI model training, meaning training use proceeds unless users take affirmative action. For EU/EEA users, the adequacy of an opt-out mechanism as opposed to opt-in consent for this processing purpose may require evaluation against GDPR requirements depending on the processing basis asserted.
Interpretive note: The lawful basis asserted under GDPR for AI training data use is not explicitly named in the reviewed policy text, creating uncertainty about whether the opt-out mechanism is sufficient for EU/EEA users.
Under this clause, query content and conversation responses are used for AI model training by default, and users must actively opt out to prevent this use. The opt-out is available via platform privacy settings or by contacting privacy@perplexity.ai.

"We may use your interactions with our services, including your queries and the responses you receive, to train, fine-tune, and improve our AI models and services. You may opt out of this use of your data by adjusting your privacy settings or contacting us at privacy@perplexity.ai.— Excerpt from Perplexity AI's Perplexity AI Privacy Policy
1) REGULATORY LANDSCAPE: This provision implicates GDPR provisions on lawful bases for processing, purpose limitation, and data subject rights, as well as CCPA provisions on use of personal information beyond the disclosed purpose. The UK ICO and EU supervisory authorities have issued guidance on the use of personal data for AI training. The FTC has signaled scrutiny of AI training data practices under unfair and deceptive practices standards. 2) GOVERNANCE EXPOSURE: High. The opt-out default for AI training data use is the most operationally significant provision in the policy for EU/EEA compliance. GDPR generally requires a valid lawful basis for each processing purpose; if legitimate interests is the asserted basis, a balancing test must be documented. If consent is the basis, opt-out is not a sufficient mechanism under GDPR and opt-in would be required. 3) JURISDICTION FLAGS: EU/EEA and UK users face heightened exposure due to GDPR and UK GDPR requirements on lawful basis and consent. California users have the right under CPRA to opt out of use of sensitive personal information beyond what is necessary to provide services. Illinois and other states with emerging AI transparency laws may impose additional disclosure requirements. 4) CONTRACT AND VENDOR IMPLICATIONS: Enterprise or API customers should assess whether their use agreements with Perplexity include provisions restricting the use of their users' data for model training, as the default policy permits this use absent opt-out. B2B contracts may need to address this use right explicitly. 5) COMPLIANCE CONSIDERATIONS: Legal teams should document the lawful basis asserted for AI training data use by jurisdiction, ensure the opt-out mechanism is technically functional and accessible, and assess whether supplementary consent notices are required for EU/EEA users. Data mapping should classify training data use as a distinct processing purpose with its own retention and access controls.
