Privacy Policy

World Time Zone Calculator is designed with privacy as a default. Here's how we handle your data.

Third-party services

  • Google Fonts: Loads typefaces (Fraunces, Manrope, IBM Plex Mono) from Google's CDN. Google's privacy policy applies to this connection.
  • Web3Forms (contact page only): If you submit the contact form, your name, email, and message are sent to Web3Forms for delivery. Their privacy policy applies.

Analytics

Your timezone data

World Time Zone Calculator reads your browser's timezone setting (via Intl.DateTimeFormat) to display your local time. This information is used entirely client-side and is never transmitted.
