Gemini Advanced — privacy & data policy

Provider: Google. PromptPrivacy score: 66/100. Last verified November 01, 2026.

What happens to your data?

Google collects user prompts, uploaded files, generated content, device information, and interaction history to provide and improve its services. When Keep Activity is enabled, chats and uploads are saved to your account and may be reviewed by human reviewers and used to train Google's AI models. Users can turn off activity tracking or use temporary chats to prevent future interactions from being retained or used for model training.

Does it train on your data?

Trains on your content by default, with an opt-out. When Keep Activity is on, Google uses user prompts, uploads, transcripts, and outputs to develop and train generative AI models and other machine learning technologies. Users can turn off Keep Activity or use temporary chats to prevent future chats from being used for AI training, provided they do not submit feedback.

Can you opt out?

Yes. Users can opt out of having their chats used to train Google's AI models by turning off the Keep Activity setting in Gemini Apps Activity or by using Temporary Chats, as long as they do not submit feedback.

Data retention

Google retains Gemini Apps activity for a default period of 18 months, which users can customize to 3 months, 36 months, or indefinite in Gemini Apps Activity. Temporary chats and chats conducted while Keep Activity is off are retained for 72 hours for service operation and safety. Chats reviewed by human reviewers are disconnected from user accounts and retained for up to 3 years.

Encryption & security

The policy does not specify encryption standards such as TLS or AES, nor does it list security certifications for Gemini Apps. It explicitly notes that messages created and sent with the Gemini app are not end-to-end encrypted by Google.

Is it safe for work?

No, Gemini Advanced under this consumer privacy notice is generally not recommended for sensitive business or workplace data. Google explicitly warns users not to enter confidential information because human reviewers assess conversations and data is used to train AI models by default. Organizations needing enterprise data protection should instead use Gemini through a work Google Workspace account, which operates under different privacy terms.
