## What is Nucleus?

Unlock the hidden code of your body with Nucleus—your ultimate AI-powered health and schedule co-pilot. 

Stop guessing what your fatigue means. Nucleus seamlessly integrates with Apple Health to decode your physiological data (HRV, Sleep, Active Energy) and converse with you in real-time, helping you optimize your daily routine like a pro.

No subscriptions. No paywalls. 100% Unlimited Access.
Powered by the state-of-the-art DeepSeek V3 model, Nucleus is entirely free to use.

CORE FEATURES:
• AI-Driven Smart Scheduling: Just chat with Nucleus. Tell it you are tired, say "Yes" to a proposed recovery plan, and watch it instantly generate an actionable schedule card for your day.
• Deep Health Decoding: Understand what your Resting Heart Rate or sleep quality actually means. Nucleus finds the hidden correlations between your metrics and your energy levels.
• Seamless Apple Health Sync: Securely connects with HealthKit to provide personalized, context-aware insights without any manual logging.

PRIVACY BY DESIGN:
Your data is yours. Nucleus operates on a highly secure, cloud-native architecture. 
• Zero Training: Your personal health data and conversations are NEVER used to train our AI models.
• Ephemeral Processing: Health metrics are analyzed in real-time to provide insights and are never permanently stored on our servers.

MEDICAL DISCLAIMER:
Nucleus is designed for informational and fitness tracking purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician regarding any medical condition.
