Privacy Policy
1. Introduction
Welcome to the MPG ↔ L/100km Converter, a completely client-side web utility. This Privacy Policy explains our practices regarding any information related to your use of the tool. We are strongly committed to protecting user privacy and operate on a strict zero-data-collection principle.
Because the entire application runs locally in your browser, we do not collect, store, transmit, or process any personal data or user content. All calculations happen on your device and disappear when you close or refresh the page.
2. Information We Do Not Collect
We do not collect any of the following:
- Personal Identifiable Information (PII) — names, email addresses, or any contact details.
- Usage or Technical Data — IP addresses, browser fingerprints, device information, or location data.
- Input Data — any MPG or L/100km values you enter are processed only in your browser and never leave your device.
- Analytics or Tracking Data — we use no analytics services, cookies, pixels, or tracking scripts of any kind.
Your fuel economy calculations remain completely private and under your control at all times.
3. How the Tool Works
All conversion logic, including the exact constants 3.785411784 L per US gallon and 1.609344 km per mile, executes entirely in your browser using JavaScript. No data is sent to any server. The tool is fully stateless and works offline once loaded.
Temporary values you type exist only while the page is open. Clearing the fields or refreshing the page removes everything immediately.
4. Third-Party Services and CDNs
The site uses Bootstrap via a public CDN for styling only. These CDNs do not set tracking cookies on our site and do not receive any information about the numbers you convert. No other third-party services are used.
5. Cookies and Tracking Technologies
This website does not use any cookies, localStorage for tracking, or any form of persistent tracking technology. Your session is completely stateless.
6. Data Security
Since we never receive your data, we cannot lose or misuse it. We still recommend following general best practices:
- Use a modern, updated browser.
- Avoid entering sensitive information if you share your screen.
- Clear your browser cache regularly if desired.
7. Children’s Privacy
The converter is suitable for all ages and does not target or collect data from children. No personal information is gathered from any user.
8. International Users
Because no data is collected or stored, the tool is compliant by design with major privacy regulations including GDPR, CCPA/CPRA, and similar laws worldwide.
9. Changes to This Policy
We may update this Privacy Policy occasionally. Any changes will be posted here with a new effective date. Continued use of the tool after changes constitutes acceptance of the updated policy.
10. Contact
If you have questions about this Privacy Policy, please feel free to reach out via the contact information on the main site.
Your privacy is our priority. This tool was built so you can convert fuel economy values with complete confidence that nothing is tracked or stored.
