Key point

Gemini subscribers' saved chat history is used to train generative AI models and may be reviewed by humans unless the Keep Activity setting is disabled.

Details

Google Gemini uses saved chat history from personal accounts, including paid subscriptions, to train generative AI models if the Keep Activity setting is enabled.
A subset of chats is reviewed by human reviewers, with Google explicitly warning users not to enter confidential information.
Chats reviewed by humans are retained for up to three years, even if the user deletes their activity.
Disabling the Keep Activity setting to prevent training use results in the loss of any chat session after 72 hours.
