Terms of Use
These terms cover your use of jetlagplanner.app, operated by XOR Limited, a company incorporated in New Zealand. By using the site you accept them.
Last updated: 7 August 2026.
The tool is free
Jet Lag Planner is provided free of charge for personal, non-commercial use. There is no account and no payment. You are welcome to share the plans you create. The site is funded by advertising.
No medical advice
The plans and articles are general wellness information, not medical advice, and not a substitute for a qualified health professional. Please read the Disclaimer in full. Decisions about your health, a sleep disorder, medication, or supplements belong with a doctor or pharmacist.
Fair use of the site
Please do not:
- scrape, crawl, or automate the site in a way that degrades it for other people;
- attempt to break, probe, or circumvent its security;
- republish the articles wholesale as your own; or
- present the tool as yours, or imply we endorse you.
Quoting a passage with credit and a link back is fine and welcome. If you want to build on the plan engine, get in touch.
Our content
The text, design, and code are owned by XOR Limited except where another source is credited. The research we cite belongs to its authors and publishers, and we link to it so you can read the original.
Advertising and third-party links
The site carries advertising served by third parties, and the articles link to outside websites. We do not choose, write, or check individual advertisements, and a link is not an endorsement. Any dealing you have with an advertiser is between you and them.
Provided "as is"
The tool is offered as is. Time-zone data, flight times, and circadian estimates can contain errors, and every plan is a population estimate rather than a prediction about your body. Treat it as a helpful starting point and use your own judgement, particularly where a mistake would be costly.
Your rights we cannot exclude
Nothing in these terms limits or excludes any right or remedy you have under the Consumer Guarantees Act 1993, the Fair Trading Act 1986, or any other New Zealand law, to the extent those rights cannot lawfully be excluded. Where you acquire or use this site for the purposes of a business, the Consumer Guarantees Act does not apply and sections 9, 12A and 13 of the Fair Trading Act are excluded, to the extent the law allows.
Liability
Subject to the section directly above, XOR Limited is not liable for any indirect or consequential loss arising from your use of the site, including a missed connection, a lost booking, lost sleep, or lost business. Where liability cannot be excluded, it is limited to the amount you paid to use the site, which is nil.
Availability
We may change, suspend, or withdraw the site or any part of it at any time. We do not promise it will always be available or uninterrupted.
Changes to these terms
We may update these terms. The date at the top shows the current version, and continued use after a change means you accept the updated terms.
Governing law
These terms are governed by the laws of New Zealand, and the New Zealand courts have non-exclusive jurisdiction over any dispute. If you use the site from another country, you are responsible for complying with the law that applies to you there. Nothing here removes any mandatory protection you have under the consumer law of your own country of residence.
