Jetlag Coach: Terms of Use

Last updated: May 8, 2026

1. Acceptance of Terms

These Terms of Use (“Terms”) govern your use of the Jetlag Coach mobile application, website, and related services (collectively, the “Service”). By accessing or using the Service you agree to be bound by these Terms.

Jetlag Coach is operated by Thomas Tartière, doing business as Jetlag Coach, located in British Columbia, Canada.

If you do not agree to these Terms, you must not use the Service.

If you obtained the Service through the Apple App Store, your license to use the Service is also governed by Apple’s standard end-user license agreement, available at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. In the event of any conflict between these Terms and Apple’s standard end-user license agreement with respect to the licensing of the Service through the Apple App Store, Apple’s standard end-user license agreement controls.

2. Eligibility

The Service is intended for individuals who are at least 18 years old. By using the Service you confirm that you meet this requirement.

3. Description of the Service

Jetlag Coach provides informational schedules intended to help travelers adjust their circadian rhythm when crossing time zones. Based on information you provide such as sleep preferences, chronotype, and travel itinerary, the Service generates recommendations related to sleep timing, light exposure, caffeine use, and optional melatonin timing.

The Service is designed to provide educational guidance and should not be interpreted as professional or medical advice.

4. Medical Disclaimer

The Service provides informational guidance related to sleep timing, circadian rhythms, and travel adaptation.

Jetlag Coach does not provide medical advice, diagnosis, or treatment. The information and schedules generated by the Service are based on general scientific principles and are not tailored to individual medical conditions.

You should consult a qualified healthcare professional before:

  • taking melatonin or other supplements
  • making significant changes to your sleep schedule
  • changing caffeine consumption habits
  • using the Service if you have a sleep disorder or other medical condition

Use of the Service is voluntary and at your own risk.

The Service does not provide real-time, operational, or safety-critical instructions and is not a substitute for professional judgment, training, experience, medical care, or applicable rules and procedures.

You agree not to use the Service while driving, operating any vehicle or machinery, or while engaged in any activity that requires your full attention or where use of the Service could create a safety risk.

Jetlag Coach does not control, operate, or supervise users’ flight itineraries, travel decisions, work schedules, safety protocols, or fitness-for-duty determinations, and assumes no duty of care in connection with such matters arising from use of the Service.

You agree not to rely on the Service as the sole basis for any decision involving safety, transportation, work performance, or physical activity.

6. Generated Plan Assumptions and Limitations

Jetlag Coach generates schedules algorithmically based on the information you provide, including sleep preferences, chronotype, and travel itinerary.

The accuracy and usefulness of generated plans depend on the accuracy and completeness of the information provided by the user.

The recommendations produced by the Service assume that users will generally follow the guidance provided in the plan, including recommendations related to light exposure, sleep timing, caffeine use, and optional melatonin timing.

The Service attempts to account for differences in individual circadian preferences, including variations in chronotype. However, the algorithms are designed for individuals whose sleep schedules and chronotypes fall within typical ranges of human sleep patterns.

Users whose sleep habits fall significantly outside common patterns, such as highly irregular schedules, shift work, or atypical sleep cycles, may experience results that differ from those anticipated by the Service.

Individual responses to circadian schedules and environmental cues such as light exposure may vary significantly between individuals. As a result, the effectiveness of any generated plan may differ from one user to another.

Jetlag Coach does not guarantee that following a generated plan will eliminate or reduce jet lag.

Users remain responsible for determining whether and how to follow the recommendations provided by the Service.

Flight, airport, itinerary, and time zone information may be provided by users or third-party data providers and may be incomplete, delayed, inaccurate, or unavailable. Users are responsible for verifying all travel details with their airline or travel provider.

7. No Guarantee of Results

Jetlag Coach is designed to provide guidance based on general circadian science principles. However, individual responses to sleep schedules, light exposure, caffeine, and supplements vary significantly.

Jetlag Coach does not guarantee that use of the Service will eliminate or reduce jet lag or produce any specific results.

8. User Responsibility

You are responsible for deciding whether and how to follow any recommendations provided by the Service.

Before following any schedule or recommendation generated by the Service, you should consider your personal health, travel circumstances, and individual needs.

Jetlag Coach does not monitor or supervise how users apply the recommendations provided by the Service.

You are also responsible for ensuring that the information you provide to the Service is accurate and up to date.

9. Notifications and Reminders

Notifications and reminders are provided for convenience only. Delivery may be delayed, blocked, or unavailable depending on device settings, operating system behavior, connectivity, time zone changes, battery settings, or notification permissions.

10. Accounts

Users may access the Service by creating an account.

You are responsible for maintaining the confidentiality of your account credentials.

11. Purchases and Subscriptions

Some features of the Service require payment.

Purchases and subscriptions are processed through the platform where the purchase is made. Purchases made in the iOS app are processed by Apple. Purchases made in the Android app are processed by Google Play. Any web purchases, where available, are processed by our payment processor. Prices, subscription duration, and billing terms are presented before purchase.

Subscriptions may renew automatically unless cancelled through your app store account settings, or through the relevant account management interface for web purchases, before the renewal date.

Subscriptions can be managed and cancelled through your app store account settings, or through the relevant account management interface for web purchases.

Cancelling a subscription stops future renewal but does not necessarily provide a refund for the current billing period. Access may continue until the end of the paid period unless otherwise stated by the applicable platform.

The Service includes a limited number of free trips. From time to time we may run promotional offers that change the number of free trips or the conditions attached to them.

Under our current launch offer, available until September 1, 2026, new users receive three free trips instead of one. The two additional promotional trips are valid for twelve months from account signup, after which any unused additional trips expire. The standard free trip is not subject to this time limit.

Free and promotional trips have no monetary value, are non-transferable, and are not redeemable for cash or refunds. We may modify, suspend, or end any promotional offer at any time, and we may change the standard free trip allowance for future users. Changes do not affect promotional trips already granted to you.

12. Refunds

Purchases made through the Apple App Store or Google Play are subject to the refund policies of the applicable app store. We do not control app store refund decisions. For web purchases, refund eligibility, if any, will be described at checkout or handled by contacting us.

We reserve the right to suspend or terminate access if these Terms are violated.
