Privacy Policy

Last updated: 3/11/2025

Overview

Your privacy is important to us. This Privacy Policy explains how our Unit Converter handles your information when you use our service. Our core principle is data minimization - we only store what's absolutely necessary for the converter to function, and we do it locally on your device.

Information Collection

Our Unit Converter is designed with privacy in mind. We do not collect, store, or transmit any personal information. All conversions are performed entirely within your browser.

Local Storage

We use your browser's local storage to save:

  • Recent conversions history (limited to last 50 conversions)
  • Theme preference (light/dark mode)
  • Last used conversion units

This data remains on your device and is never transmitted to our servers or any third parties. You can clear this data at any time by:

  • Using the "Clear History" button in the conversion history panel
  • Clearing your browser's local storage
  • Using your browser's private/incognito mode

Data Security

Since all data is stored locally on your device, security is managed by your browser's built-in protections. We implement best practices for web security, including:

  • HTTPS encryption for all connections
  • Content Security Policy (CSP) headers
  • Secure cookie attributes
  • XSS protection headers

Analytics and Tracking

We use privacy-focused analytics to understand how the converter is used and improve our service. This analytics implementation:

  • Does not use cookies
  • Does not collect personal information
  • Does not track users across websites
  • Only records aggregate usage data

Third-Party Services

Our Unit Converter does not integrate with any third-party services or APIs. All conversion calculations are performed locally using built-in conversion formulas.

Children's Privacy

Our service is suitable for users of all ages and complies with the Children's Online Privacy Protection Act (COPPA). We do not knowingly collect any personal information from children under 13 years of age.

Changes to Privacy Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by:

  • Posting the new Privacy Policy on this page
  • Updating the "Last updated" date at the top of this page

Your Rights

Under various privacy laws (GDPR, CCPA, etc.), you have certain rights regarding your personal information. However, since we don't collect any personal information, these rights primarily apply to the local data stored on your device, which you have complete control over.

California Privacy Rights

Under the California Consumer Privacy Act (CCPA), California residents have specific rights regarding their personal information. Since our Unit Converter does not collect personal information, we do not sell, share, or process personal information as defined by the CCPA.

International Users

Our Unit Converter is designed to be compliant with international privacy laws and regulations, including the EU's General Data Protection Regulation (GDPR). Since we don't collect personal data, most GDPR requirements regarding data processing do not apply to our service.
