## Frequently Asked Questions (FAQ) for Gemini CLI

### 1. Is my code, including prompts and answers, used to train Google's models?

This depends entirely on the type of auth method you use.

- **Auth method 1:** Yes. When you use your personal Google account, the Gemini Code Assist Privacy Notice for Individuals applies. Under this notice, your **prompts, answers, and related code are collected** and may be used to improve Google's products, which includes model training.
- **Auth method 2a:** Yes. When you use the Gemini API key Gemini API (Unpaid Service) terms apply. Under this notice , your **prompts, answers, and related code are collected** and may be used to improve Google's products, which includes model training.
- **Auth method 2b, 3 & 4:** No. For these accounts, your data is governed by the Google Cloud or Gemini API (Paid Service) terms, which treat your inputs as confidential. Your code, prompts, and other inputs are **not** used to train models.

### 2. What are "Usage Statistics" and what does the opt-out control?

The "Usage Statistics" setting is the single control for all optional data collection in the Gemini CLI. The data it collects depends on your account type:

- **Auth method 1:** When enabled, this setting allows Google to collect both anonymous telemetry (like commands run and performance metrics) and **your prompts and answers** for model improvement.
- **Auth method 2a:** When enabled, this setting allows Google to collect both anonymous telemetry (like commands run and performance metrics) and **your prompts and answers** for model improvement. When disabled we will use your data as described in the [How Google Uses Your Data](https://ai.google.dev/gemini-api/terms#data-use-unpaid).
- **Auth method 2b:** This setting only controls the collection of anonymous telemetry. Google logs prompts and responses for a limited period of time, solely for the purpose of detecting violations of the Prohibited Use Policy and any required legal or regulatory disclosures
- **Auth methods 3 & 4:** This setting only controls the collection of anonymous telemetry. Your prompts and answers are never collected, regardless of this setting.

You can disable Usage Statistics for any account type by following the instructions in the [Usage Statistics Configuration](./cli/configuration.md#usage-statistics) documentation.
