Google explicitly warns users not to share sensitive personal information — such as health, financial, or identifying details — in their Gemini conversations.
This warning signals that Google acknowledges Gemini conversations are not a safe or private channel for sensitive data, and shifts responsibility to the user if sensitive data is shared and subsequently accessed or used.
The sensitive data warning functions as a liability-limiting disclosure. For regulated industries (healthcare, financial services, legal), this provision signals that Gemini is not a compliant channel for handling protected information under HIPAA, GLBA, or attorney-client privilege frameworks without additional safeguards.

Your conversations with Gemini, including any personal or sensitive information you share, may be reviewed by Google employees and used to train AI models. Chat history is retained for up to 18 months by default, and Google may use this data across its broader ecosystem of services. You can delete your Gemini conversation history by visiting myactivity.google.com and disabling or clearing Gemini Apps Activity.
