Privacy Policy
Last updated: January 17, 2026
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.
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
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.
Account Information
When you create an account to purchase licenses, we collect and store:
- Email address (for authentication and license delivery)
- Password (hashed and salted using industry-standard algorithms)
- Organization name (for license assignment)
- Payment information (processed securely by Stripe; we don't store credit card details)
- License purchases and activation history
Cookies and Tracking
- Essential Cookies: Session cookies for authentication (required for login)

- No Third-Party Tracking: We don't use advertising pixels, social media trackers, or cross-site tracking

We do not send marketing emails or sell your email address to third parties.

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.
