Privacy Policy

Last updated: January 2024

1. Privacy by Design

World Time Zone Calculator is designed from the ground up to respect your privacy. Because the time zone calculation logic is powered entirely by your browser's Intl API, no scheduling data is ever sent to our servers. All your city selections, dates, and times remain safely on your device.

2. Information We Do Not Collect

• We do not track your IP address to guess your location.
• We do not use tracking cookies or third-party analytics (like Google Analytics).
• We do not share any data with advertising networks.

3. Information We Collect

When you use our contact form, we collect the name and email address you provide solely for the purpose of responding to your inquiry. This data is processed securely via our form provider, Web3Forms. We do not add you to any mailing lists.

Our hosting provider (Vercel) automatically logs basic request data (such as browser type, referring page, and timestamp) for security and operational purposes. This data is anonymized and rotated regularly.

4. Local Storage

In the future, World Time Zone Calculator may use standard browser `localStorage` to remember your favorite cities or dark mode preferences. This data will never leave your device.

5. Changes to This Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
