Your private conversations with AI characters can become part of the training data that shapes the AI system itself, with limited ability to prevent this after the fact.
Character.AI collects extensive personal data including chat conversations, voice recordings, and behavioral data, which may be used to train AI models and shared with advertising and analytics partners. Users who create popular AI characters should be aware that those characters — and potentially associated personal information embedded in them — may be retained even after account deletion. You can request deletion of your personal data or opt out of targeted advertising by submitting a request at https://support.character.ai/hc/en-us/requests/new or emailing privacy@character.ai.
