Runnerd is not a medical device.

The training recommendations in Runnerd are based on established sports-science models (TRIMP by Banister, VO₂ max, heart-rate zones) and your personal data from Apple Health. They are meant as guidance for healthy adults — not as a substitute for medical advice, diagnosis, or treatment.

Please keep in mind:

• Talk to a doctor before starting a new training program, especially if you have pre-existing conditions, are pregnant, or are returning after an extended break.
• Listen to your body. If you experience pain, severe fatigue, dizziness, or unusual symptoms: stop running and seek medical advice.
• Values like Readiness, VO₂ max, and Recovery are estimates derived from wearable data. They can be wrong — don’t trust them blindly.

You are responsible for your training decisions. We do our best to build Runnerd solidly and honestly — but we cannot accept liability for injuries, health problems, or missed training.
