Privacy Policy

1. Introduction

Calorie Deficit Calculator ("we", "our", or "us") is a free, frontend-only web application. This privacy policy explains that we do not collect, store, or transmit any personal health information.

2. Data Collection

Our calculator runs entirely in your browser. All inputs (age, sex, height, weight, activity level, goals) are processed locally using JavaScript. We do not send this data to any server, API, or third-party service.

3. Local Storage

We may use the browser's localStorage to remember your preferred unit system (metric/imperial) or to save your last inputs for convenience. This data remains on your device and can be cleared by clearing your browser data.

4. Analytics

If we ever implement analytics (e.g., page view counters), they will not collect calculator inputs. Currently, this website does not use any analytics or tracking cookies.

5. Third-Party Services

We do not use third-party advertising networks or data brokers. External links (e.g., to scientific references) are provided for informational purposes and are governed by their own privacy policies.

6. Children's Privacy

This website is intended for adults aged 18 and above. We do not knowingly collect information from children.

7. Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated effective date.
