READ BEFORE USE

1. Assumption of Risk
The practice of ice bathing (cold water immersion), breathwork (such as the Wim Hof Method), and related activities involves inherent risks of severe physical injury, permanent disability, and death. These risks include, but are not limited to, hypothermia, cold shock response, heart attack, stroke, loss of consciousness (shallow water blackout), and drowning. By using the "Zero" app and engaging in these activities, YOU VOLUNTARILY ASSUME ALL RISKS, known and unknown, associated with your participation.

2. Mandatory Medical Consultation
Cold exposure places extreme physiological stress on the body. You must consult with a qualified physician before starting any cold exposure or breathwork regimen. This is especially critical if you possess pre-existing conditions (e.g., cardiovascular disease, high blood pressure, diabetes, epilepsy, asthma) or are pregnant. Never practice ice bathing if you are under the influence of alcohol or drugs.

3. No Medical Advice
The content provided by "Zero" (including timers, guides, community posts, and health data tracking) is for informational, educational, and recreational purposes only. It does not constitute medical advice, diagnosis, or treatment. Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition.

4. Limitation of Liability
To the fullest extent permitted by applicable law, the creators, developers, operators, and affiliates of "Zero" expressly disclaim liability for any direct, indirect, incidental, special, or consequential damages resulting from your use of this app or your practice of cold water immersion. You agree that you are solely responsible for your own safety and well-being.

5. Safety Guidelines
* NEVER practice breathwork in or near water. Do breathwork only in a safe place (e.g., on a couch or bed).
* NEVER force your limits. Listen to your body.
* ALWAYS ensure you have a spotter or are in a safe environment when entering cold water.
