HIGH⚠ CAUTIONMED
Standard plan: personal, non-commercial use only. Enterprise terms at perplexity.ai/hub/legal/enterprise-terms-of-service. Email/calendar integration data explicitly excluded from AI model training.
“To the extent the laws in your jurisdiction do not recognize the legal basis of legitimate interest or another legal basis specified above for a particular purpose, you consent to the processing of your personal information for that purpose through using the Services.”
Perplexity uses mere use of the Services as implied consent for processing where 'legitimate interests' is not recognized as a valid legal basis. This is a broad fallback consent mechanism that may not be valid under GDPR or other strict privacy regimes.
