Gemini (Free) — privacy & data policy

Provider: Google. PromptPrivacy score: 63/100. Last verified August 26, 2026.

What happens to your data?

Google collects your conversations, uploaded media, and device context to provide responses and train its AI models. Human reviewers inspect a portion of de-identified chats to improve quality and safety. You can turn off activity tracking to prevent conversations from being used to train future AI models.

Does it train on your data?

Google uses prompts, conversation history, and uploaded content to develop and train generative AI models and machine learning technologies when Keep Activity is enabled. You can prevent your future data from being used for AI training by turning off Keep Activity or using Temporary Chats (unless you explicitly submit feedback). Audio and Gemini Live recordings are not used for model training by default unless you opt in.

Can you opt out?

Yes. You can opt out of model training and long-term activity storage by turning off the Keep Activity setting in your Gemini Apps settings or by using Temporary Chats.

Data retention

Activity is saved by default for 18 months, with user-configurable auto-deletion periods of 3 months, 36 months, or indefinite retention. When Keep Activity is turned off or when using temporary chats, interactions are kept for 72 hours for operational and safety purposes. Any chats and feedback selected for human review are disconnected from your account and retained for up to 3 years.

Encryption & security

Not specified. The policy mentions that messages created and sent with the Gemini app are not end-to-end encrypted and avatar data is stored securely in your account, but specific in-transit or at-rest encryption protocols and security certifications are not detailed.

Is it safe for work?

No. Google explicitly instructs users not to enter confidential or sensitive information because human reviewers evaluate chats and data is used for model training. Workplaces should use Google Workspace business tiers with dedicated enterprise agreements instead.
