Elevation Calc terms of use
Effective September 27, 2026
These terms apply to your use of the Elevation Calc app. By downloading or using Elevation Calc, you agree to them.
1. Licence
Elevation Calc is licensed, not sold, under Apple's Standard Licensed Application End User License Agreement (EULA). These terms add to that agreement. If they conflict, Apple's EULA governs.
2. Purchase and refunds
Elevation Calc is a one-time purchase through the App Store. There are no subscriptions, in-app purchases, or ads. Apple processes all payments, and refund requests are handled by Apple at reportaproblem.apple.com.
3. Results are a working aid, not professional advice
Elevation Calc is a calculator. Its results are meant to help with planning and layout, and they are not engineering, architectural, or other professional advice. Before you cut material, order supplies, or build, you are responsible for:
- checking every measurement and result yourself
- confirming that your work meets the building codes, permits, and standards that apply where you are
Elevation differences and slope drops are calculated from the numbers you enter. They are not a substitute for a survey, and they do not account for local codes or drainage requirements.
4. Rounding
Results shown in feet and inches are rounded to the nearest 1/16 inch. Decimal results are shown to up to four decimal places, so allow for this when accuracy matters.
5. Provided "as is"
Elevation Calc is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of accuracy, fitness for a particular purpose, and merchantability, to the fullest extent permitted by law. We do not warrant that the app will be error-free.
6. Limitation of liability
To the fullest extent permitted by law, Fairfax AppWorks is not liable for any indirect, incidental, special, or consequential damages, or for any loss of materials, time, money, or property, arising from your use of Elevation Calc or reliance on its results. Our total liability for any claim will not exceed the amount you paid for the app. Some jurisdictions do not allow certain limitations, so some of these may not apply to you.
7. Changes
We may update these terms. The current version will always be posted on this page with its effective date. Continuing to use Elevation Calc after a change means you accept the updated terms.
8. Governing law
These terms are governed by the laws of the State of California, USA, except where your local consumer protection laws require otherwise.
