Privacy Policy

Last Updated: June 4, 2026

Welcome to ClockZone.online. We are dedicated to providing you with an accurate and beautiful world clock and time conversion application while fully respecting and preserving your personal privacy. This privacy document details how we handle cookies, cache settings, and interact with advertising networks like Google AdSense.

1. Information We Do Not Collect

ClockZone.online is engineered to calculate time zone values and offsets entirely in your local browser sandbox.

  • We do not record, transmit, or store your IP addresses or geographic telemetry data on any external servers.
  • Our timezone autocomplete search executes purely inside client-side script memory, meaning none of your keystrokes or location queries are sent to us.
  • We do not require user account registrations, emails, or personal identification data to use any features.

2. Google AdSense & Cookie Compliance Disclosures

We integrate third-party vendor networks, specifically Google AdSense, to serve advertisements when you visit our website.

Google uses cookies to serve ads based on a user's prior visits to your website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet.

Please note the following choices regarding your ad tracking preferences:

  • Users may opt out of personalized advertising by visiting Google's Ads Settings page.
  • Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the YourAdChoices (AboutAds) consumer opt-out site.

3. Browser LocalStorage Caching

To optimize user interaction and save your settings, we use the browser's native LocalStorage capacity to store the following layout choices:

  • cz_theme: Remembers if you prefer Dark Mode or Light Mode layout.
  • cz_is24Hour: Caches your preferred time display standard (12-hour or 24-hour display format).
  • cz_pinned: Saves your list of customized pinned world clock cards.

This data is kept locally on your machine and never synced to our networks. You can clear this anytime by resetting your browser storage data.

4. Web Analytics

We may utilize aggregate web telemetry logs to monitor overall service availability and operational metrics. This logs non-identifiable browser types, visit timestamps, and page loading performance values to help us optimize page load speed and crawler layout indexes.

5. Amendments to this Privacy Policy

We reserve the right to modify this statement as necessary to maintain compliance with advertising networks or browser API updates. Any revisions will be reflected directly on this page with a revised "Last Updated" timestamp.
