Privacy Policy

Last updated: January 17, 2026

Our Commitment to Privacy

At Quadrastack, we believe in privacy by design. Our tools are built to work offline-first, with minimal data collection and maximum transparency. This policy explains how we handle your information across our CLI tool, VSCode extension, and website.

CLI Tool (Quadrastack CLI)

What We DON'T Collect

  • No telemetry or analytics data
  • No test execution data or results
  • No API endpoints, headers, or request/response data
  • No file contents or playbook configurations
  • No environment variables or secrets
  • No usage statistics or crash reports

How It Works

The CLI runs entirely on your local machine. All playbook files, test data, mock servers, and execution results stay on your computer. No internet connection is required for core functionality.

License Validation (Optional)

If you use a Pro or Business license, the CLI validates your license key locally using cryptographic signatures. License validation:

  • Happens entirely offline using public key cryptography
  • Does not phone home or send data to our servers
  • Your license key is stored locally in your environment variables
  • No license usage tracking or expiration checks over the network
VSCode Extension

What We DON'T Collect

  • No file access logs or edit history
  • No syntax highlighting or autocomplete usage data
  • No extension activation or usage patterns
  • No workspace or project information
  • No code snippets or file contents

How It Works

The VSCode extension provides syntax highlighting, autocomplete, and inline execution features. All functionality operates locally within your VSCode environment. The extension communicates only with the Quadrastack CLI installed on your machine—no external servers involved.

Our Privacy-First Philosophy

Unlike many API testing tools, Quadrastack is designed for privacy from the ground up. Your test data never leaves your machine. We built our tools to work offline because we believe your API tests, endpoints, and sensitive data should stay private. We only collect the minimum necessary information to provide licensing services—nothing more.
