Privacy Policy

What Lacy collects

Nothing. Lacy Shell is a local shell plugin that runs entirely on your machine. It does not phone home, collect usage data, or send telemetry of any kind.

How routing works

When you type in your terminal, Lacy classifies your input locally as either a shell command or natural language. Shell commands execute in your shell as usual. Natural language queries are forwarded to whichever AI CLI tool you have configured (Claude Code, Gemini CLI, OpenCode, etc.).

Lacy itself never contacts any external server. Any data sent to an AI provider is governed by that provider’s privacy policy, not ours — because Lacy is just routing your input to a tool you already installed and configured.

The website (lacy.sh)

This website uses Umami for privacy-friendly, cookie-free analytics. Umami is self-hosted, does not track personal data, and is GDPR compliant. No cookies are set. No personal information is collected or stored.

Third-party services

The install script (curl -fsSL https://lacy.sh/install | bash) downloads Lacy from GitHub. GitHub’s privacy policy applies to that download. After installation, Lacy does not contact GitHub or any other service.

The website loads fonts from Google Fonts. Google’s privacy policy applies to font delivery.

Open source

Lacy Shell is MIT licensed and fully open source. You can audit every line of code at github.com/lacymorrow/lacy.

Data retention

Lacy does not store any data. There is no database, no log file, and no history of your queries beyond what your shell and your AI tool already keep. Your shell history is managed by your shell (ZSH or Bash), not by Lacy. If your AI CLI tool keeps conversation logs, that is governed by that tool’s own configuration.

Children’s privacy

Lacy Shell does not knowingly collect any information from anyone, including children under 13. Since no data is collected at all, there is nothing to disclose or delete.

Changes to this policy

If this policy changes, the updated version will be posted here with a new “last updated” date. Since Lacy collects no data, significant changes are unlikely.
