HoldIt: Apnea Tables — Terms of Use

Last updated: November 9, 2026

These Terms of Use (“Terms”) govern your use of the HoldIt: Apnea Tables mobile application (the “App”), provided by Krzysztof Barczyński (the “Developer”). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.

1. What the App is — and is not

The App is a timer and training log for dry (on-land) breath-hold exercises, intended for informational and recreational purposes only. The App is not a medical device. It does not provide medical advice, diagnosis, treatment, monitoring or supervision, and it cannot detect loss of consciousness or any other medical emergency.

2. Safety rules you must follow

• Use the App only on dry land, seated or lying down. Never use it in, under or near water.
• Never practise breath-holding in water alone. Shallow-water blackout can occur without warning and can cause drowning, even in strong and experienced swimmers.
• Do not hyperventilate before breath-holds.
• Never use the App while driving, operating machinery, bathing, standing, or in any situation where loss of consciousness could cause injury.
• Consult a qualified physician before use if you have, or suspect you have, any heart, lung, blood-pressure, seizure, or other medical condition, or if you are pregnant.
• Stop immediately if you feel dizzy, light-headed, tingling, confused, or experience vision changes or any discomfort.
• Training tables, targets, scores, ranks, creatures and trophies in the App are motivational features only. They are not recommendations to hold your breath for any particular length of time.

3. Eligibility

You must be at least 18 years old, or have the permission and supervision of a parent or legal guardian, to use the App.

4. Assumption of risk

Breath-hold training carries inherent risks, including hypoxia, loss of consciousness, injury and death. You understand these risks and voluntarily assume all of them. You are solely responsible for deciding whether, how, where and when to train, and for your own safety.

5. Release

To the maximum extent permitted by applicable law, you release and discharge the Developer from any and all claims, demands and liabilities arising out of or relating to your use of the App or any breath-hold activity you undertake, whether or not you were using the App at the time.

6. Disclaimer of warranties

The App is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy, or uninterrupted or error-free operation. Timers, sounds, voice cues and haptics may fail, be delayed or be inaudible.

7. Limitation of liability

To the maximum extent permitted by applicable law, the Developer shall not be liable for any personal injury, death, or any direct, indirect, incidental, special, consequential or punitive damages arising out of or relating to your use of, or inability to use, the App. Where liability cannot be excluded, the Developer’s total liability is limited to the amount you paid for the App in the twelve months before the claim (or USD 0 if the App was free).

8. Indemnity

You agree to indemnify and hold harmless the Developer from any claims, losses and expenses (including reasonable legal fees) arising from your use of the App or your breach of these Terms.

9. Apple

These Terms are between you and the Developer, not Apple Inc. Apple is not responsible for the App or its content. Apple’s Standard Licensed Application End User License Agreement also applies, and Apple and its subsidiaries are third-party beneficiaries of these Terms.

10. Changes and governing law

The Developer may update these Terms; continued use of the App after an update means you accept the updated Terms. These Terms are governed by the laws of the State of California, USA, without regard to conflict-of-law rules. If any provision is unenforceable, the rest remain in effect.
