Terms of Use

Last updated April 29, 2026

By installing or using GhostFingers, you agree to these terms. Please read them. They are short.

The app, plainly

GhostFingers is a free iOS app that reads public weather and ocean data and displays a surf forecast. The app does not require an account, does not contain advertising, and does not include in-app purchases.

Not for navigation

Wave height, wind, tide, and rating values shown in GhostFingers are model output. They are estimates, not measurements taken at the moment you read them. Conditions in the ocean change quickly. Do not use this app for navigation, search and rescue, commercial fishing decisions, or any other use where being wrong about the water could hurt you or someone else.

Surf at your own risk

Surfing is a risk activity. The information in this app is provided to help you decide where and when to paddle out. It does not replace your own judgment, local knowledge, lifeguard advice, or first-hand observation of conditions at the spot. You alone are responsible for your decisions in and around the water.

No warranty

GhostFingers is provided "as is," without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, and non-infringement. The app's data sources may change, fail, or return inaccurate values. The forecast may be wrong.

Limitation of liability

To the extent permitted by law, the developer of GhostFingers is not liable for any damages — direct, indirect, incidental, special, consequential, or punitive — arising from your use of the app, including injury, property loss, or missed waves.

Acceptable use

You agree not to:

• Reverse-engineer the app for the purpose of building a competing product.
• Misuse public data sources by routing them through the app to bypass their rate limits.
• Use the app in any way that violates the laws of your jurisdiction.

Third-party data

The app fetches publicly available forecast data from NOAA, Open-Meteo, and CDIP. Those services have their own terms and acceptable-use policies. By using the app you also accept the public-data terms of those services as they apply to you. The app does not control or endorse the accuracy of third-party data.

Changes

If these terms change, the updated version will be posted at this URL with a new revision date. Continued use of the app after a change means you accept the updated terms.

Governing law

These terms are governed by the laws of the State of California, without regard to conflict-of-law principles.
