Privacy Policy

Last updated: 2025-09-25

We respect your privacy. This site performs time zone calculations locally in your browser using the IANA time zone database exposed through the Web Internationalization API. Your inputs (zones, date, time) are not transmitted to our servers.

Cookies & Advertising

We use Google AdSense to display ads. Google may use cookies or local storage to serve and measure personalized and non‑personalized ads. You can learn more about how Google uses data from sites that use its services at Google’s partner‑sites policy.

You can manage ad personalization at adssettings.google.com. Your browser also provides controls to block or delete cookies.

Analytics

We may collect basic, aggregated metrics such as page views and referrers to understand site performance. We do not store personally identifiable information.

Data Security

We use HTTPS and industry‑standard hosting. Since the core calculator runs locally, minimal data is processed on our servers.

Your Choices

• Use content blockers if you prefer fewer ads or trackers.

Changes

We may update this policy. Material changes will be reflected here with a new “Last updated” date.
