Privacy Policy

Last updated: 12 July 2026

This Privacy Policy explains how JetLagCal ("we", "us", "our") handles information when you use jetlagcal.com (the "Site"). We've kept it plain and honest. In short: our calculators run entirely in your browser, and we don't collect personal accounts or sell your data.

1. Information you enter into calculators

The details you type into our calculators — cities, dates, times, ages and preferences — are processed entirely within your own browser. This information is not transmitted to us, is not stored on any server, and is not saved after you close or refresh the page. We never see it.

2. Information collected automatically

Like most websites, our hosting provider and analytics may record standard technical information such as your approximate location (from your IP address), browser type, device type, referring page and the pages you visit. This is used to keep the Site secure and to understand, in aggregate, how it is used. It does not identify you personally.

3. Cookies and advertising

We use advertising to keep the Site free. We may work with Google AdSense and its partners to display ads. These third parties may use cookies or similar technologies to serve and measure ads, and in some cases to show ads based on your prior visits to this and other websites.

  • Third-party vendors, including Google, use 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 visits to this Site and/or other sites on the internet.
  • You can opt out of personalised advertising by visiting Google Ads Settings, and you can learn about further options at aboutads.info/choices and youronlinechoices.com.

4. Contact form

Our contact page does not send data through this Site. It simply opens a draft email in your own mail application, which you choose whether to send. If you email us, we'll use your message and email address only to reply and to improve the Site.

5. Children's privacy

The Site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

6. Your choices and rights

Because we don't hold personal accounts or profiles, there is generally nothing for us to retrieve or delete about you. You can control cookies through your browser settings and opt out of personalised ads using the links above. Depending on where you live, you may have rights under laws such as the Australian Privacy Act, the GDPR or the CCPA; contact us if you'd like to exercise them.

7. Third-party links

The Site may link to other websites. We aren't responsible for the privacy practices of those sites and encourage you to read their policies.

8. Changes to this policy

We may update this policy from time to time. When we do, we'll revise the "Last updated" date above. Significant changes will be reflected on this page.
