Once your data is shared with third parties, Pinterest's privacy policy no longer governs how those parties use your information, meaning you have less control over your personal data.
Pinterest collects a broad range of personal data including browsing behavior, device information, location, and inferred interests, which is used to serve targeted advertising and train AI/ML models. Your data may be shared with a wide range of third parties including advertisers and analytics partners, which could have meaningful implications for your privacy.
