What cookies we use

Advertising cookies. Google AdSense sets cookies to serve and measure ads, and where you have consented, to personalise them. These are third-party cookies controlled by Google. Learn more at Google’s advertising policies.

Preference storage. Some tools keep your settings (for example, your saved time zone list, or the fact that you dismissed the cookie notice) in your browser’s local storage. This data never leaves your device.

What we do not use

We do not set cookies to track your calculator inputs, and we do not sell personal data.

Managing cookies

You can block or delete cookies through your browser settings; the calculators keep working without them. To control ad personalisation, visit Google Ads Settings. EEA and UK visitors are shown a consent choice before personalised advertising is loaded.
