Legal
Terms of Use
Last updated 2 October 2026 · Applies to MOD Calculator for iOS
1. Agreement
By downloading or using MOD Calculator you agree to these terms. The app is published by vandestadt.com, registered in the Dubai International Financial Centre, Dubai, United Arab Emirates. If you do not agree, do not use the app.
2. Licence
We grant you a personal, non-transferable licence to use MOD Calculator on devices you own or control, as permitted by the App Store Terms of Service. You may not redistribute, resell, or reverse-engineer the app.
3. Dive safety and accuracy of results
MOD Calculator is a planning aid for divers who are already certified to dive nitrox. It is not training, not a dive computer, and not a substitute for your own tables, your instructor, or your agency’s limits.
The app applies a published formula to the two numbers you give it. It knows nothing about your dive plan, your gas supply, the conditions, your physiology, or your fitness to dive. Exceeding a maximum operating depth risks central nervous system oxygen toxicity, which underwater can be fatal. Verify every figure independently before you dive it.
4. Warranty and liability
The app is provided as is. To the extent permitted by DIFC law, we exclude implied warranties and limit our liability.
5. Apple is not a party to this agreement
This agreement is between you and vandestadt.com, not Apple. Apple has no obligation to provide support for the app, and is a third-party beneficiary with the right to enforce these terms against you.
6. Governing law
These terms are governed by the laws of the Dubai International Financial Centre. Questions go to info@vandestadt.com.
