Gemini Advanced — privacy & data policy

Provider: Google. PromptPrivacy score: 64/100. Last verified August 26, 2026.

What happens to your data?

Google collects your prompts, uploaded media, device context, and usage activity to provide responses, personalize features, and train AI models. Selected conversations are detached from your identity and examined by human reviewers to evaluate accuracy and safety. You can manage retention settings, delete past chats, or disable activity tracking to stop data from being used in AI training.

Does it train on your data?

Google uses prompts, chats, uploads, instructions, and feedback by default to develop and improve its services, including training machine learning and generative AI models. Portions of conversations are evaluated by human reviewers. Users can prevent future data from being used to train models by turning off the 'Keep Activity' setting or initiating Temporary Chats (provided no direct feedback is submitted). Audio recordings, Gemini Live videos, screenshares, and Notebook source files are excluded from AI model training by default.

Can you opt out?

Yes. Users can opt out of having their chats used for AI model training and human review by turning off the 'Keep Activity' setting or by using Temporary Chats. Audio, Gemini Live video, and screenshare recordings are also excluded from model improvement by default unless manually enabled.

Data retention

Gemini Apps Activity is retained for a default duration of 18 months, which users can adjust to 3 months, 36 months, or keep indefinitely. Users may also manually delete conversations at any time. When Keep Activity is disabled or temporary chats are used, data is retained for 72 hours to deliver responses and maintain service integrity. Any chats sampled for human review are disconnected from user accounts and retained for up to three years. Avatar voice and face recordings are automatically deleted after three years of inactivity.

Encryption & security

The policy explicitly states that messages created and sent through the Gemini app are not end-to-end encrypted. Specific technical standards such as TLS transit encryption, AES at-rest encryption, or compliance certifications (e.g., SOC 2, ISO 27001) are not specified in this document.

Is it safe for work?

No. This consumer tier is not recommended for confidential business use because conversations are logged, subject to human review, and used for model training by default. Google explicitly advises against submitting confidential information. Organizations should utilize dedicated Google Workspace work accounts governed by commercial data protection agreements.
