Privacy Policy

Effective Date: April 2026  |  Last Updated: April 13, 2026

Overview

Calc Labz (“we,” “us,” or “our”) is committed to protecting your privacy. This Privacy Policy explains what information we collect, how we use it, and your rights. Calc Labz is operated by Sagar Sahni from India.

Key point: All calculations on Calc Labz happen entirely in your browser. We do not send your calculation inputs or results to any server.

1. Information We Collect

1.1 Information You Provide

We do not require registration, login, or personal details to use our calculators. If you contact us by email, we receive your email address and message content solely to respond to your inquiry.

This information is collected only after you provide consent through our cookie consent banner. It is used in aggregate form to understand traffic patterns and improve our calculators.

All calculations run locally in your web browser using JavaScript. No calculation inputs or results are transmitted to our servers or any third party. Your financial, health, and personal data never leaves your device.

2. Cookies & Local Storage

Calc Labz uses the following types of storage:

  • Essential (Local Storage): Theme preference (dark/light mode), favorites list, and PWA settings. These are stored locally on your device and not transmitted anywhere.

4. Children’s Privacy

Calc Labz is a general-purpose educational tool. We do not knowingly collect personal information from children under 13. Our calculators do not require any personal data to function.

5. Data Retention
