Cookie policy

The short version

The clocks and converters on this site work with no optional cookies at all. Optional cookies exist only for analytics and advertising, and they are off until you accept them.

Necessary storage

We store a small number of values in your browser's local storage: your saved cities, your home time zone, whether you prefer a 12- or 24-hour clock, your light or dark theme, your recent conversions, and your cookie choice itself. These stay on your device and are never sent to us.

Analytics cookies (optional)

If you accept analytics, we may use Google Analytics to count page views and see which tools are used. This helps us decide what to improve. Declining has no effect on how the site works for you.

Advertising cookies (optional)

If you accept advertising, Google AdSense and its partners may set cookies to measure ad performance and personalise the ads you see. Declining means any ads shown are not personalised using cookie data from this site.

Changing your mind

You can change your choice at any time. Selecting the button below clears your stored preference and shows the consent banner again.

You can also block or delete cookies in your browser settings. See our privacy policy for how data is handled more broadly.
