Privacy Policy
Last updated: April 2026
Your privacy is important to us. This Privacy Policy explains how Clockzilla (“we”, “us”, or “our”) collects, uses, and protects information when you visit clockzilla.io.
Information We Collect
Clockzilla operates entirely within your browser. We do not collect, store, or transmit personal information such as names, email addresses, or contact details. We do not require you to create an account to use the service.
Time Synchronization Requests
To provide accurate time, Clockzilla's backend server sends requests to third-party time servers (TimeAPI.io, Cloudflare) and caches the results. Your browser communicates with our backend server for time sync. These requests contain only standard HTTP protocol data such as IP address and user-agent, which are used solely for serving the request and are not stored long-term.
Local Data
Your theme preference, language, and cookie consent choice may be stored in your browser's localStorage. This data never leaves your device and is used only to remember your preferences between visits. You can clear it at any time through your browser settings.
Advertising (Google AdSense)
This site uses Google AdSense to display advertisements. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or other sites on the Internet. You can opt out of personalized advertising by visiting Google's Ads Settings at https://adssettings.google.com. You can also opt out of third-party vendors' use of cookies for personalized advertising by visiting https://www.aboutads.info.
Analytics
We may use Google Analytics to understand how visitors use the site in aggregate. Google Analytics collects anonymized data about page views, referrers, and general geographic region. This information is used only to improve the site and is never linked to individual users. You can opt out by installing the Google Analytics Opt-out Browser Add-on.
Third-Party Services
The time servers we query have their own privacy policies. We encourage you to review them. We do not share your data with any third party beyond the minimal information necessary to fulfill time sync requests.
Children's Privacy
Clockzilla does not knowingly collect information from children under 13. Our service is a general-purpose time tool with no age-restricted content. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.
Your Rights
Depending on your jurisdiction (including GDPR in the EU and CCPA in California), you may have the right to access, correct, or delete personal data we hold about you. Because we do not collect personal data, there is generally nothing for us to access or delete. For cookie-related preferences, please use the cookie consent banner or your browser settings.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be reflected on this page with an updated revision date. Material changes will be highlighted at the top of the page for a reasonable period.
