By downloading or using STAmaster, you agree to these Terms of Service. If you do not agree, do not use the app.
STAmaster is a training tool for Static Apnea (breath-hold) practice. It provides timers, training tables, progress tracking, and coaching guidance to support your freediving training.
STAmaster is a training aid, not a medical device. The app does not diagnose, treat, cure, or prevent any medical condition. Heart rate, HRV, and SpO2 data displayed in the app are for informational training purposes only. Always consult a qualified medical professional before beginning any breath-hold training programme.
Never practise breath-holding alone in water. Breath-hold training carries inherent risks, including shallow water blackout, which can result in drowning. STAmaster enforces a buddy-check before wet static sessions, but the app cannot guarantee your safety. You are solely responsible for training in a safe environment with a qualified safety buddy present.
You acknowledge that breath-hold training is an inherently risky physical activity. By using STAmaster, you voluntarily assume all risks associated with this activity. Code3 is not liable for any injury, loss, or damage arising from your use of the app.
You agree to use STAmaster only for its intended purpose of personal breath-hold training. You will not reverse-engineer, decompile, or attempt to extract the source code of the app.
STAmaster and all associated content, design, and branding are the property of Code3. You may not reproduce, distribute, or create derivative works from any part of the app without written permission.
We strive to keep STAmaster available and functional, but we do not guarantee uninterrupted access. We may update, modify, or discontinue features at any time.
To the maximum extent permitted by law, Code3 shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of STAmaster.
We may update these terms from time to time. The "Last updated" date at the top will reflect any changes. Continued use of the app after changes constitutes acceptance of the updated terms.
