Last updated: September 4, 2026

1. Introduction

Welcome to CalcWorker ("we", "our", or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you visit our website calcworker.com.

2. Information We Collect

CalcWorker is designed to be a privacy-first utility hub. We do not collect, store, or share any personal data. All calculations (currency conversion, tax estimation, hourly rate calculation, etc.) are performed locally in your browser using JavaScript. No user input data is ever sent to our servers.

3. Cookies and Local Storage

We use browser local storage solely to cache exchange rates for offline functionality and to remember your theme preference (Dark/Light mode). These are essential for the website to function properly and do not track your browsing activity across other sites.

4. Third-Party Services

Our currency converter fetches exchange rates from public APIs (open.er-api.com). These requests are anonymous and do not contain your IP address or personal information. We do not use Google Analytics or any tracking pixels without explicit consent.

5. Children's Privacy

Our services are not directed to individuals under the age of 13. We do not knowingly collect personal information from children.

6. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page with an updated date.
