Privacy Policy

Last Updated: February 2026

At ToolBlaster, we believe privacy should be the default. This Percentage Calculator is designed to be a "zero-knowledge" tool, meaning we do not want, need, or collect your personal data.

1. Data Collection

We do not collect any personal data.

When you use this calculator, all calculations are performed locally on your device using JavaScript. Your numbers (inputs) and results are never sent to our servers. We cannot see what you are calculating.

2. Local Storage

To improve your experience, this tool uses your browser's "Local Storage" feature to:

• Remember your last inputs so you don't lose your work if you refresh the page.
• Store a small history of your last 3-5 calculations locally.

This data stays on your specific device and browser. You can clear it at any time by clearing your browser cache or clicking the "Reset" button on the calculator cards.

3. Cookies

This specific tool does not use tracking cookies. We do not use third-party advertising cookies or analytics pixels on this page.

4. Third-Party Services

This page is hosted as a static site. We do not use third-party analytics services (like Google Analytics) or advertising networks on this specific utility page.
