Does Character.AI train its models on your data?
Yes — Character.AI trains on your data by default; you have to opt out.
Character.AI uses your chat content with Characters to train and improve its proprietary generative models by default, with an in-product opt-out that is only officially documented for EEA/UK users.
Can you opt out?
Only users in the EEA or UK get a documented toggle: Settings → Data & Privacy (app) or Settings → Account → Manage Account & Data → Model Improvement (web), then deselect "Improve the Model for Everyone." Users outside the EEA/UK have no equivalent self-serve training opt-out and effectively rely on exercising regional rights (e.g. CCPA) or deleting their account.
Zero retention / DPA
No zero-data-retention or DPA offering is published for the consumer product. Conversations are collected and retained; even after opting out of training, data may still be used for other service improvements.
What the listicles get wrong
The nuance content farms miss: the opt-out exists only for EEA/UK; for users elsewhere there is no documented training toggle, and opting out stops future training but not other reuse of your conversations. The Aug 27 2025 policy update broadened collection rights and drew a user backlash.
