Privacy Policy

Last updated: October 25, 2026

1. Introduction

Welcome to ArchCalc. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our application.

2. Information Collection

The ArchCalc desktop application runs entirely on your machine. It has no account system and does not collect or send personal data, telemetry, usage statistics or system information. Your history, workspaces and quotes are stored locally and can be exported or deleted from Settings at any time.

This website uses Vercel Web Analytics to count page views. It collects anonymous, aggregated data (such as the page visited, referrer, country and device type), does not use cookies and does not identify you.

3. Data Security

We use administrative, technical, and physical security measures to help protect any personal information you provide. Because the majority of operations happen locally, your data remains secure on your own hardware.

4. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
