## Ton

**Profile:** Legal-technical | Institutional voice | Informative-prescriptive register | Expert level

Google's legal/product documentation adopts a formal terms-of-service voice combining legal precision with clarity for developers. Structured language (data collection policies, opt-out procedures, authentication requirements) that establishes a contractual framework. Neutral and professional tone, typical of legal documentation, avoiding ambiguity. Systematic structure (scope → data practices → user rights → opt-out) that facilitates understanding of compliance. The markdown format on GitHub makes this technical documentation accessible to developers. Typical of legal documents aimed at developers (AWS ToS, Azure Privacy), balancing legal requirements with ease of use for developers.

## Pense-betes

- **ToS/Privacy vary** depending on authentication method and account type
- **4 authentication methods**: Google account with Code Assist Individuals, Standard/Enterprise, Gemini API key with Developer API, Vertex AI GenAI API
- **Individuals + unpaid API**: prompts/answers/code **collected and used** for training
- **Standard/Enterprise + paid API + Vertex AI**: prompts/answers/code **NOT collected**, treated confidentially
- **Usage Statistics**: single control for optional data collection, scope varies by account type
- **Opt-out available**: possibility to decline Usage Statistics
- **Differentiated confidentiality**: free = data collected, paid/enterprise = confidentiality guaranteed

## RésuméDe400mots

The Terms of Service and Privacy Notice documentation for the Gemini CLI (Command-Line Interface) reveals a complex and highly differentiated structure of privacy and data-use policies, critically dependent on the authentication method and account type used. This document is crucial because it determines whether the user's prompts, responses, and associated code will be collected and potentially used for model training.

**Four Distinct Authentication Scenarios**

**Scenario 1: Google account + Gemini Code Assist for Individuals**
Users are subject to the general Google Terms of Service and a specific Privacy Notice for Code Assist Individuals. Under this arrangement, **prompts, responses, and associated code are collected and may be used** to improve Google products, including model training purposes.

**Scenario 2: Google account + Gemini Code Assist for Standard/Enterprise Users**
The Google Cloud Platform Terms of Service and a distinct Privacy Notice for Standard/Enterprise apply. **Crucially**, for these users, **prompts, responses, and code are treated as confidential, are not collected, and are explicitly not used** for model training.

**Scenario 3: Gemini API key + Gemini Developer API**
Terms differ depending on unpaid vs paid service. **Unpaid** services: the Gemini API Terms of Service for Unpaid Services apply, **permitting collection** of prompts/answers/code for model improvement. **Paid** services: the Gemini API Terms of Service for Paid Services govern, **treating inputs as confidential** and preventing collection for model training.

**Scenario 4: Gemini API key + Vertex AI GenAI API**
Subject to the Google Cloud Platform Service Terms and the Google Cloud Privacy Notice. In this scenario, **prompts, responses, and code are considered confidential, are not collected, and are not used** for model training.

**Usage Statistics: Unified Control, Variable Scope**

The document also addresses "Usage Statistics," serving as a single control for all optional data collection in the Gemini CLI. The scope of data collected via this setting **varies by account type**. For individual Code Assist users and unpaid Developer API users, enabling Usage Statistics **permits collection of anonymous telemetry PLUS prompts/answers/code** for model improvement. For Standard/Enterprise Code Assist users and Vertex AI GenAI API users, this setting controls **only anonymous telemetry**, since their prompts and code are never collected. Paid Developer API users have their prompts/responses **logged for a limited time** solely for policy violation detection. **All users can opt out** of Usage Statistics collection.

This documentation structure highlights a clear monetization strategy: free services fund their operational cost through data collection for model improvement, while paid and enterprise services guarantee full confidentiality as a premium value proposition.
