Terms of Service

Last updated: February 2026

Acceptance of Terms

By downloading, installing, or using the Skuba mobile application ("the App"), you agree to be bound by these Terms of Service. If you do not agree to these terms, do not use the App.

Description of Service

Skuba is a dive planning toolkit that provides calculators, gas blending tools, and decompression planning features for scuba divers. The App is designed as a planning aid and reference tool.

Important Safety Disclaimer

Scuba diving, including decompression diving, is an inherently dangerous activity that carries a risk of serious injury or death. Skuba is a planning and reference tool only. It is NOT a substitute for proper dive training, certification, or professional judgment.

  • Always dive within the limits of your training and certification.
  • Never rely solely on any software — including this App — for dive safety decisions.
  • All decompression planning outputs should be independently verified and cross-checked with other sources, including your dive computer and qualified instructors.
  • The App does not replace a dive computer, proper training, or professional dive planning instruction.
  • You are solely responsible for your own safety and the safety of your dive team while diving.
  • Individual physiological responses to pressure, gas loading, and decompression vary and cannot be fully predicted by any model or software.

Assumption of Risk

By using the App, you acknowledge that scuba diving is a dangerous activity and that you voluntarily assume all risks associated with diving, including risks arising from the use of dive plans, calculations, or any other output generated by the App. You agree that you will rely on your own training, experience, and judgment — and not solely on the App — when making decisions related to dive safety.

Free and Premium Features

Most features in Skuba are available free of charge. The Deco Planner is a premium feature available via subscription ($4.99/month, first month free) or lifetime purchase ($29.99). Subscriptions are managed through the Apple App Store or Google Play Store and are subject to their respective terms.

Subscriptions and Billing

  • Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period.
  • Payment is charged to your Apple ID or Google account at confirmation of purchase.
  • You can manage or cancel subscriptions in your device's account settings.
  • Refunds are handled by Apple or Google according to their policies.

Intellectual Property

The App, including its design, code, content, and branding, is owned by Lazuli Global and is protected by intellectual property laws. You may not copy, modify, distribute, or reverse-engineer any part of the App.

No Warranty

The App is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, or non-infringement. Lazuli Global does not warrant that the App will be error-free, uninterrupted, or free of harmful components, or that any calculations, plans, or outputs produced by the App will be accurate, complete, or suitable for any particular dive.

Limitation of Liability

To the maximum extent permitted by applicable law, Lazuli Global and its officers, directors, employees, and agents shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages — including but not limited to personal injury, death, property damage, loss of data, or loss of profits — arising from or related to your use of or inability to use the App, any calculations or dive plans generated by the App, or any dive activities undertaken in reliance on information provided by the App, regardless of the theory of liability and even if Lazuli Global has been advised of the possibility of such damages.

Accuracy of Calculations

The App uses industry-standard algorithms (including Buhlmann ZHL-16C) and precision arithmetic to produce its calculations. However, no software can guarantee error-free results. Decompression models are mathematical approximations of complex physiological processes and do not account for all individual risk factors. Users must always verify critical dive planning data through multiple independent sources and should never treat the App's output as the sole basis for dive safety decisions.

Changes to Terms

We reserve the right to modify these terms at any time. Continued use of the App after changes constitutes acceptance of the modified terms.

Governing Law

These terms shall be governed by and construed in accordance with applicable laws, without regard to conflict of law provisions.
