Google’s Gemini AI uses saved chat history from personal subscriptions for model training unless users disable the 'Keep Activity' setting. Even with a paid plan, transcripts may be reviewed by human reviewers, though Google claims they are disconnected from user accounts. However, the company explicitly warns against entering confidential information.
Chats reviewed by humans are retained for up to three years even after deletion. To opt out, users must turn off 'Keep Activity' in settings, which causes chat sessions to expire after 72 hours. Many subscribers were unaware that paying does not prevent their data from being used as training material.
This practice has sparked concern among users who believed paid tiers offered more privacy.
