Terms of Service — Kairos
Last updated: July 7, 2026
These terms govern your use of the Kairos app (“the app”). Please also read the Health & Safety Disclaimer, which is part of these terms, and the Privacy Policy.
By downloading or using the app, you agree to these terms. If you do not agree, do not use the app.
Who provides the app
The app is provided by its developer (“the developer,” “we,” “us”). The developer may later assign these terms and the app to an affiliated company (for example, a company through which the developer operates); your continued use after such a change means you accept it, and these terms otherwise stay the same.
License
We grant you a personal, non-exclusive, non-transferable, revocable license to use the app on Apple devices you own or control, for your own non-commercial use, in accordance with these terms and the App Store Terms of Service. We keep all rights not expressly granted.
What the app is
Kairos suggests times to do outdoor activities by combining public weather, marine, air-quality, and astronomical data with the preferences you set. Its suggestions are informational estimates, not guarantees, professional advice, or instructions. You are responsible for deciding whether, when, and how to do any activity. See the Health & Safety Disclaimer for the details that matter most.
Acceptable use
You agree not to:
- use the app for any unlawful purpose, or in any way that could harm you or others;
- reverse-engineer, decompile, or attempt to extract the source code, except to the extent the law expressly permits;
- interfere with, overload, or disrupt the app or the third-party services it relies on, or attempt to access them other than through the app’s normal use;
- resell, redistribute, or commercially exploit the app or its output without our written permission.
Third-party data and services
The app depends on data from third parties (including Apple Weather / WeatherKit, NOAA / NOS CO-OPS tide services, and Open-Meteo). We do not control that data and do not warrant its accuracy, availability, or timeliness. Those providers’ own terms and privacy policies apply to their data. The app may be unavailable or degraded if a provider changes, limits, or discontinues its service.
Subscriptions and purchases
The app is currently offered free of charge. We may introduce optional paid features or subscriptions in the future. If we do:
- purchases are processed by Apple through your App Store account, subject to Apple’s terms, not handled by us directly;
- any auto-renewing subscription renews for the stated period until you cancel; you can manage or cancel it in your App Store account settings, and cancellation takes effect at the end of the current period;
- prices, billing periods, and what each tier includes will be disclosed to you at the point of purchase before you are charged;
- except where required by law or Apple’s policies, payments are non-refundable; refund requests are handled by Apple.
Introducing paid features does not retroactively charge you for use before the change.
Changes to the app and to these terms
We may update, change, or discontinue the app or any feature at any time. We may also update these terms; material changes will be reflected here with a new “last updated” date, and your continued use after a change means you accept the updated terms.
Termination
You may stop using the app at any time by deleting it. We may suspend or end your license if you materially breach these terms. Sections that by their nature should survive termination (disclaimers, limitation of liability, and governing law) will survive.
No warranty
The app is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the app or its data will be accurate, reliable, uninterrupted, error-free, or available at any given time. Some jurisdictions do not allow the exclusion of certain warranties, so some of the above may not apply to you.
Limitation of liability
To the fullest extent permitted by law, the developer will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, profits, or goodwill, arising out of or relating to your use of (or inability to use) the app — including any decision you make based on its suggestions or data, and any activity you undertake. To the fullest extent permitted by law, the developer’s total liability for all claims relating to the app will not exceed the greater of (a) the amount you paid for the app in the 12 months before the claim, or (b) US $50. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
Assumption of risk and indemnity
Outdoor activities carry inherent risks. You knowingly and voluntarily assume all risk arising from activities you choose to do, as described in the Health & Safety Disclaimer. You agree to indemnify and hold the developer harmless from claims arising out of your misuse of the app or your violation of these terms or of any law or third-party right.
Apple App Store
You acknowledge that:
- these terms are between you and the developer only, not with Apple, and Apple is not responsible for the app or its content;
- Apple has no obligation to provide maintenance or support for the app;
- if the app fails to conform to any applicable warranty, you may notify Apple and Apple may refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app;
- Apple is not responsible for addressing any claims relating to the app, including product-liability, regulatory, or consumer-protection claims, or claims that the app infringes another party’s intellectual-property rights;
- you represent that you are not located in a country subject to a U.S. Government embargo or designated as “terrorist supporting,” and are not on any U.S. Government list of prohibited or restricted parties;
- Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
Governing law
These terms are governed by the laws of the State of California, without regard to its conflict-of-laws rules, except where local consumer-protection law that applies to you says otherwise. Nothing here limits any non-waivable rights you have under the law of your place of residence.
