Data privacy and model training policies are primary concerns for millions of users interacting with Character.AI in 2026. Whether utilizing conversational bots for creative writing, emotional dialogue, or personal roleplay, users want clear guarantees regarding whether their private chat logs, custom character definitions, and chat histories are harvested to train future AI language models.
In this technical privacy audit, EmberGF examines Character.AI’s updated Terms of Service, Privacy Policy, data retention windows, opt-out mechanisms, and account deletion protocols to provide an evidence-based assessment of user data protection.
Does Character.AI Use Your Private Chats for Model Training?
According to Character.AI’s official 2026 Privacy Policy, user interactions with public and unlisted AI characters may be processed to maintain service safety, enforce content moderation filters, and improve model performance.
However, Character.AI provides user privacy controls under the Privacy Settings dashboard, allowing account holders to manage data collection preferences. While standard conversation logs are processed through automated safety filters, users can limit secondary data sharing by adjusting telemetry toggles.

4 Steps to Maximize Privacy on Character.AI
- Disable Model Improvement Telemetry: Navigate to Settings → Privacy & Security and disable data sharing for AI model enhancement.
