Gyral Tides Terms and Conditions

Last updated: 2026-07-31

Not a navigation tool

Gyral Tides is for information and entertainment only. It is not a navigation aid and must not be used for navigation, passage planning, or any decision affecting safety of life or property. Tides and weather are predictions, and charts are shown for reference only. Always rely on official, up-to-date charts and proper marine navigation equipment.

"As is", no warranty

Gyral Tides is provided "as is" without warranties of any kind, express or implied, including accuracy, availability, or fitness for a particular purpose.

Third-party data

Much of what Gyral Tides displays comes from third parties, including NOAA and the U.S. National Weather Service, Apple Weather, Open-Meteo, OpenStreetMap, Wikipedia, and Apple Maps. We do not control these sources and do not guarantee the continuous availability, timeliness, or accuracy of any third-party feed. Outages, gaps, delays, and errors originating upstream are outside our control. Your use of that data is also subject to the providers' own terms and licenses, listed on the in-app Data Sources screen.

To the maximum extent permitted by law, Gyral LLC is not liable for any damages arising from your use of, or reliance on, Gyral Tides or its data.

Acceptable use

Don't misuse the app or its backend services — including attempts to disrupt, overload, reverse-engineer, or gain unauthorized access.

Intellectual property

The Gyral Tides name, app, and original content are owned by Gyral LLC. Third-party data is owned by its respective providers and used under their licenses (see the in-app Data Sources screen).

App license

Your license to install and use Gyral Tides is granted under Apple's standard Licensed Application End User License Agreement, which applies to apps obtained from the App Store. The terms on this page are in addition to it and cover matters specific to Gyral Tides.
