Terms of Use

Last updated: July 5, 2026

These Terms of Use (“Terms”) govern your use of the websites and mobile applications provided by Rhumb Line Apps LLC (“Rhumb Line Apps,” “we,” “us,” or “our”), including ICW Planner (the “App”). By downloading or using the App, you agree to these Terms. If you do not agree, do not use the App.

Safety notice — please read. The App is a planning and informational aid only. It is not a navigation system and must never be used as a sole means of navigation or for any decision affecting the safety of life, property, or the environment. Tide and current values are predictions; bridge schedules, clearances, and hazards can change without notice; and mile markers and routes are approximate. Always navigate using official, up-to-date NOAA charts and U.S. Coast Guard publications, proper equipment, and prudent seamanship.

1. License

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable, revocable license to use the App on Apple-branded devices you own or control, as permitted by the App Store Terms of Service. You may not copy, modify, reverse-engineer, redistribute, or create derivative works from the App except as allowed by law.

2. Free and Pro features; purchases

The App offers free features and optional paid “Pro” features available as a one-time purchase or an auto-renewing subscription. All purchases are processed by Apple through the App Store and are subject to Apple’s terms. Prices are shown in the App before purchase and may change.

Auto-renewing subscription terms

Payment is charged to your Apple Account at confirmation of purchase.
The subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period.
Your account is charged for renewal within 24 hours prior to the end of the current period, at the rate disclosed in the App.
You can manage or cancel your subscription, and turn off auto-renew, in your Apple Account settings after purchase.
A one-time (“lifetime”) purchase is not a subscription and does not auto-renew.

Except where required by law or Apple’s policies, purchases are non-refundable. Refund requests are handled by Apple.

3. Acceptable use

You agree to use the App lawfully and not to interfere with its operation, attempt to gain unauthorized access, or misuse the third-party data sources the App relies on.

4. Third-party data

The App displays information derived from third-party and government sources, including NOAA and the U.S. Coast Guard. We do not create this underlying data and do not warrant its accuracy, completeness, timeliness, or availability.

5. Disclaimer of warranties

THE APP AND ALL CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY INFORMATION IS ACCURATE OR CURRENT.

6. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, RHUMB LINE APPS AND ITS MEMBERS, OFFICERS, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, PROPERTY, OR GOODWILL, ARISING OUT OF OR RELATING TO YOUR USE OF (OR INABILITY TO USE) THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE APP WILL NOT EXCEED THE AMOUNT YOU PAID US FOR THE APP IN THE 12 MONTHS BEFORE THE CLAIM. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

7. Indemnification

You agree to indemnify and hold harmless Rhumb Line Apps from any claims or damages arising out of your misuse of the App or violation of these Terms.

8. Apple

These Terms are between you and Rhumb Line Apps only, not with Apple. Apple is not responsible for the App or its content. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

9. Changes

We may update these Terms from time to time. Continued use of the App after changes take effect constitutes acceptance of the updated Terms.

10. Governing law

These Terms are governed by the laws of the State in which Rhumb Line Apps LLC is organized, without regard to conflict-of-laws principles, except where local consumer-protection law requires otherwise.
