These Terms of Service ("Terms") form a binding agreement between you ("you" or "your") and the developer[s] of this app ("we," "us," or "our") and govern your access to and use of the Fireman’s Calculator mobile application for iPhone and iPad (the "App"). The app name is subject to change.
PLEASE READ THESE TERMS CAREFULLY. THEY CONTAIN A CRITICAL SAFETY NOTICE (SECTION 3), DISCLAIMERS OF WARRANTY (SECTION 4), AN ASSUMPTION OF RISK (SECTION 5), AND A LIMITATION OF LIABILITY (SECTION 7).
By downloading, installing, accessing, or using the App, and by accepting the disclaimer presented within the App, you confirm that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, do not download, install, or use the App, and delete it from your device.
You must be at least the age of majority in your jurisdiction, and legally able to enter into a binding contract, to use the App.
Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to download and use one copy of the App on any Apple-branded device that you own or control, solely for your personal, non-commercial study and reference purposes, and in accordance with the Apple App Store Terms of Service and Usage Rules.
This is a license, not a sale. We and our licensors retain all right, title, and interest in and to the App.
The App is a study, reference, and exam-preparation aid for fire-service hydraulics. It is NOT a fireground tool and must NOT be used to make decisions during any emergency, incident, or live fire operation.
All outputs are estimates produced by simplified models. Real-world hydraulics vary with equipment, water supply, hose condition, elevation, temperature, and many other factors, and results may differ from actual conditions. Before relying on any value produced by the App, you must independently verify it against the policies of your Authority Having Jurisdiction (AHJ), your department's standard operating procedures, applicable manufacturer specifications, and the current edition of IFSTA and any other applicable standard.
You are solely responsible for any decision you make. The App does not provide professional, engineering, safety, or operational advice, and no output of the App is a substitute for the training, judgment, and procedures of qualified fire-service personnel.
THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS OR IMPLIED. THIS INCLUDES, WITHOUT LIMITATION, ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, RELIABILITY, AND COMPLETENESS, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. NO ADVICE OR INFORMATION OBTAINED FROM THE APP CREATES ANY WARRANTY NOT EXPRESSLY STATED IN THESE TERMS.
We do not warrant that the App will be uninterrupted, error-free, or free of defects, or that any defect will be corrected.
