Privacy Policy

• No account is required and none is offered.
• No analytics, advertising, or tracking cookies are used.
• No cookies are set at all.
• Your location is never requested — there is no geolocation prompt.
• Clocks, conversions and timers are computed in your browser, not on a server.
• Preferences and saved boards live in your browser's local storage and stay on your device.
• Two kinds of network request exist: city search to this site, and icon loading from the Iconify CDN. Both are described below.

Every clock, time zone conversion, countdown, timer and astronomical calculation on this site is performed locally by your browser, using your device clock and the IANA time zone database that ships inside your browser and operating system. The values you enter into a converter, a meeting planner or a calendar export are processed in the page and are never sent anywhere.

Your browser's reported time zone (for example Europe/Madrid) is read so that clocks can show offsets relative to you. This is a time zone, not a location, it is read through a standard browser interface that requires no permission, and it is used only inside the page. It is not transmitted and not stored.

Some tools remember your choices between visits — the cities on your world clock board, whether you prefer analog or digital, and similar settings. These are written to your browser's local storage, which is a per-device, per-browser store that is never automatically sent to a server.

You can clear it at any time through your browser's settings for site data. Doing so resets those preferences and nothing else; no copy exists anywhere for us to delete.

City search.Typing into a city search box sends the characters you typed to this site's own search endpoint, which searches the full city dataset and returns matches. The request contains the search text and nothing else — no identifier, no cookie, no profile. As with any web request, the server necessarily receives your IP address in order to reply.

Icons. Interface icons are loaded from the Iconify CDN (api.iconify.design). This is a third party, and like any CDN it can see your IP address and the fact that a request came from this site. It receives nothing about what you enter into any tool. Iconify publishes its own privacy terms.

Fonts.Web fonts are served from this site's own domain — they are downloaded at build time rather than fetched from Google Fonts, so no request goes to a font provider when you visit.

The hosting provider that serves this site keeps standard access logs, as effectively all web hosting does. These typically record IP address, the page requested, a timestamp and a user-agent string, and exist for security and reliability purposes. They are not used to build any profile, are not combined with anything else, and are not shared or sold.

No names, email addresses, phone numbers or payment details are collected by the site, because nothing here asks for them. If you email contact@worldclock.tools, that message is held in an ordinary mailbox for as long as needed to deal with it, and is used for nothing else.

The contents of any tool — the times you convert, the cities you add, the events you count down to, the details you put into a calendar export — are never transmitted or retained.

The site is suitable for general audiences and collects no personal information from anyone, including children.

Data protection law, including the GDPR, gives you rights of access, correction, erasure and portability over personal data held about you. Because this site holds no personal data beyond transient hosting logs, there is in practice nothing to access, correct or export. If you have a question about that, or wish to raise a concern, write to contact@worldclock.tools.

If this policy changes — for instance if a new data source or provider is introduced — the updated version will be posted here with a new date at the top of the page. Material changes will be described rather than quietly folded in.

See also the terms of use and the about page, which explains where the time zone and city data comes from.

Does worldclock.tools use cookies?

No. The site sets no cookies at all — not for analytics, not for advertising, not for sessions. It does use your browser's local storage to remember things like your saved city board, but that data stays on your device and is never transmitted.

Do you track my location?

No. The site never calls the browser's geolocation API, so you will never see a location permission prompt. Your time zone — not your location — is read from your browser so clocks can show offsets relative to you, and that value is used only inside the page.

Is any data sent to a server?

Only city search. When you type into a city search box, the letters you typed are sent to this site's own search endpoint so it can search the full 34,000-city dataset. Nothing identifying is attached. Separately, icons are loaded from the Iconify CDN, which necessarily sees your IP address as any CDN would.
