What we collect
The site works without an account and does not ask you to submit personally identifiable information. Page state, such as selected cities and time format, may be stored in the URL or local storage; hosting providers may also create standard access logs.
Cookies and local storage
We use browser local storage, for example localStorage, to remember preferences such as theme, language, and saved cities. Google advertising and analytics services may use cookies or similar identifiers for ad delivery, measurement, fraud prevention, and relevance. You can clear or limit these in your browser.
Third-party services
The site uses Google Analytics, Google AdSense on content and tool pages, and Microsoft Clarity on selected pages to understand aggregate usage, support advertising, and improve the experience. These services may receive page URLs, IP-derived location, browser and device information, interaction events, cookies, or similar identifiers. Google ad requests may involve domains such as google.com, doubleclick.net, googlesyndication.com, and googleadservices.com.
Advertising and editorial separation
Advertising helps support the site, but ads do not determine time zone calculations, city coverage, editorial notes, or correction decisions. Content and tool pages may show Google AdSense ads, while trust pages such as Privacy, Terms, Editorial Policy, Feedback, and Time Zone Data And Accuracy are kept ad-free so visitors can review policies without ad placement pressure.
Advertising cookies and opt-out
Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this site or other websites. Google advertising cookies help Google and its partners show ads based on visits to this site and/or other sites. You can manage or opt out of personalized advertising through Google Ads Settings, and you can use AboutAds choices to opt out of some third-party vendors' personalized advertising cookies where available.
Security
The site uses HTTPS to reduce risks of man-in-the-middle attacks and content tampering. Avoid sharing sensitive information on untrusted networks.
Your choices
You can clear browser cache, local storage, and cookies, and you can limit personalized ads or analytics through browser settings, Google ad settings, or consent controls where available.
Retention and minimization
Preferences stored in local storage remain on your device until you clear them. Server logs, analytics records, advertising records, and consent signals are handled by the relevant hosting or third-party provider under its own retention rules. TheWorldTimeMap avoids account creation, payment collection, and private calendar uploads so the core time tools can run with less personal data.
