Terms of Use
Last updated November 6, 2026
These terms cover your use of the iMahina app, made by Salted Logic Inc. (“we”) in Honolulu, Hawaiʻi. By using iMahina, you agree to them. They add to Apple’s Licensed Application End User License Agreement, which also applies.
Using iMahina
You may use iMahina on Apple devices you own or control, for your own personal, non-commercial use. Please don’t copy, resell, or redistribute the app, or try to take it apart to get at its code or content.
Subscriptions
- iMahina offers three auto-renewing yearly subscriptions: Sky, Sea, and Sky & Sea, which includes both. Each is at the price shown in the app before you buy.
- Each starts with a 2-week free trial. If you don’t cancel at least 24 hours before the trial ends, your Apple account is charged for the first year.
- The subscription renews each year unless you cancel at least 24 hours before the end of the current year. Your Apple account is charged for the renewal within the 24 hours before it.
- You can manage or cancel your subscription in your Apple account settings. Cancelling stops the next renewal. You keep access until the end of the period you’ve paid for.
- Any unused part of a free trial ends when you buy a subscription.
- If you change plans, for example from Sky to Sky & Sea, Apple shows the new price before you confirm.
- Payments and refunds are handled by Apple, under Apple’s terms.
What iMahina is, and isn’t
iMahina is a starting point for learning about Hawaiian moon time, built on cited sources and today’s astronomy. It isn’t a cultural authority, and it doesn’t speak for any family, island, or community’s own reckoning.
Moon phases, rise and set times, dates, and events in the app are calculated and approximate. Tide charts in Sea are predictions from NOAA, the U.S. National Oceanic and Atmospheric Administration, and aren’t live readings. Don’t rely on any of these for navigation, fishing or ocean safety, or any decision where an error could cause harm. When the app and the sky disagree, go with the sky.
Your writing
What you write in iMahina belongs to you and stays on your phone. We don’t keep a copy, so we can’t recover it if your phone is lost or the app is deleted. Your phone’s own backups are the way to keep it safe.
Our work
The app’s text, artwork, audio, and design are © Salted Logic Inc. and Naiʻa Lewis, all rights reserved. You may share the images iMahina makes for you with the Share button.
The Hawaiian names and the traditional knowledge iMahina draws on aren’t ours to own. They come from generations of Hawaiian observers, scholars, and practitioners, who are credited in the app.
Town and place names come from GeoNames, used under the Creative Commons Attribution 4.0 license.
No warranty
iMahina is provided as it is, without warranties of any kind, to the fullest extent the law allows. We work to keep it accurate and running, but we can’t promise it will be error-free or always available.
Limit on liability
To the fullest extent the law allows, Salted Logic Inc. isn’t liable for indirect or consequential losses from your use of iMahina. Our total liability to you won’t be more than what you paid for iMahina in the 12 months before the claim.
Changes
We may update these terms as the app grows. When we do, the date at the top changes. If you keep using iMahina after a change, the new terms apply.
Law
These terms are governed by the laws of the State of Hawaiʻi, without regard to its conflict-of-law rules.
