Privacy Policy

Last updated: November 12, 2026

This privacy policy explains what information is processed when you visit PlanetClocks (planetclocks.com) and how you can control it.

Information we collect

We do not ask you to create an account and we do not collect your name, email or other personal information unless you contact us by email. Clocks, converters, timers and alarms run entirely in your browser. Preferences such as your world clock list, last countdown, timer duration or alarm time are stored in your browser's local storage on your own device and are never sent to us. You can delete them at any time by clearing your browser's site data.

Like most websites, our web server automatically records technical information in log files, such as your IP address, browser type, the page requested and the date and time of the request. We use these logs only to keep the site secure and working, and delete them after a limited period.

Advertising and cookies

We use Google AdSense to show advertising, which keeps the site free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google's Ads Settings, or opt out of some third-party vendors' use of cookies for personalized advertising at www.aboutads.info. To learn more about how Google uses data, see How Google uses information from sites or apps that use our services.

Visitors in the European Economic Area, the United Kingdom and Switzerland are asked for consent before personalized ads and non-essential cookies are used, through a consent message provided by Google. You can change your choice at any time via the privacy settings link shown by that message. Where required by law (for example under the GDPR, the UK GDPR, the Brazilian LGPD or California privacy laws), you have rights to access, correct or delete personal data and to object to its processing.

Cookies we use

The site itself does not set tracking cookies. Cookies may be set by Google for advertising, measurement and fraud prevention. Most browsers let you block or delete cookies in their settings; the tools on this site keep working without them.

Children

The site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

External links

Our pages may link to other websites. We are not responsible for their content or privacy practices.

Changes and contact

We may update this policy; the date above shows the latest revision. Questions about privacy can be sent to dingguoshengai@gmail.com.
