# Privacy > CommitBrief has no telemetry. The website logs aggregate analytics only. Effective May 26, 2026 Canonical URL: https://commitbrief.com/legal/privacy/ --- ## The CLI CommitBrief the CLI collects **nothing**. It has no telemetry endpoint, no analytics beacon, no auto-update check, and no crash reporter. The network behavior depends on which provider you selected: - **Anthropic, OpenAI, Gemini** — CommitBrief makes one HTTPS call per review to the provider's API endpoint, carrying the contents of your diff and your `COMMITBRIEF.md` rules file. - **Ollama** — no outbound calls. The CLI talks only to `http://localhost:11434` (or whatever `base_url` you configured) on your own machine. - **`claude-cli` / `gemini-cli`** — CommitBrief makes no network calls itself. It launches the host CLI (`claude` or `gemini`) as a subprocess and pipes the prompt to it. The host CLI then makes its own network calls against the provider it's authenticated with; its privacy policy and data handling apply. ## What providers see Each provider has its own privacy policy and data-retention behavior. Review them before sending sensitive code: - [Anthropic](https://www.anthropic.com/legal/privacy) - [OpenAI](https://openai.com/policies/privacy-policy/) - [Google Gemini](https://policies.google.com/privacy) - [Claude Code](https://www.anthropic.com/legal/privacy) (used by `claude-cli`) - [Gemini CLI](https://policies.google.com/privacy) (used by `gemini-cli`) ## This website The website serves static HTML/JS from a CDN. It uses no cookies and no third-party analytics. The CDN provider may log aggregate request metadata (IP, user-agent, path) for abuse prevention; we do not access or correlate those logs. ## Contact Questions: open an issue at [github.com/CommitBrief/commitbrief/issues](https://github.com/CommitBrief/commitbrief/issues) or email .
