Terms of Service

Effective Date: February 3, 2026

Please read these Terms of Service (“Terms”) carefully before using the Boring Cardio mobile application (“App”). These Terms constitute a legally binding agreement between you (“User,” “you,” or “your”) and Ryland Lillibridge, doing business as Boring Cardio (“Developer,” “I,” “me,” or “my”), governing your access to and use of the App.

By downloading, installing, or using the App, you acknowledge that you have read, understood, and agree to be bound by these Terms. If you do not agree to these Terms, do not use the App.

1. Description of Service

Boring Cardio is a fitness application that provides treadmill workout suggestions, including speed, incline, and duration recommendations intended to help users target specific heart rate training zones (such as Zone 2 and Zone 3). The App uses physiological models and user-provided data (such as age, weight, fitness level, and heart rate information) to generate these suggestions.

The App is a general fitness tool. It does not monitor your heart rate in real time, does not connect to medical devices, and does not provide medical diagnoses, treatment recommendations, or clinical assessments of any kind.

2. Eligibility

You must be at least 18 years of age to use the App. By using the App, you represent and warrant that you are at least 18 years old and have the legal capacity to enter into these Terms.

3. Health and Fitness Disclaimer

THIS IS THE MOST IMPORTANT SECTION OF THESE TERMS. PLEASE READ IT CAREFULLY.

3.1 Not Medical Advice

The App provides general fitness information for educational and informational purposes only. The content, recommendations, and workout suggestions provided by the App are NOT intended to be, and must not be taken as, medical advice, diagnosis, or treatment. The App is NOT a medical device and is not intended to diagnose, treat, cure, or prevent any illness, metabolic disorder, disease, or health condition.

No doctor-patient, therapist-patient, or other healthcare provider relationship is created between you and the Developer through your use of the App.

3.2 Consult Your Physician

You should consult your physician or other qualified healthcare provider before starting any exercise program, including any workout suggested by this App. This is particularly important if you (or your family) have a history of high blood pressure or heart disease, if you have ever experienced chest pain when exercising or at rest, if you smoke, have high cholesterol, are obese, are pregnant or nursing, are diabetic, or have a bone or joint condition that could be made worse by a change in physical activity.

Do not begin any exercise program suggested by the App if your physician or healthcare provider advises against it.

3.3 Assumption of Risk

Exercise carries inherent risks, including but not limited to the risk of physical injury, disability, or death. You acknowledge and voluntarily assume full responsibility for any risks of loss, injury, or damage—personal or otherwise—that may result from your use of the App or participation in any physical activity undertaken in connection with the App.

YOU ASSUME ALL RISKS ASSOCIATED WITH ANY PHYSICAL ACTIVITIES THAT YOU ENGAGE IN WHILE USING OR IN CONNECTION WITH THE APP.

3.4 Accuracy of Estimates

The App’s workout suggestions, heart rate zone calculations, calorie estimates, and other fitness-related outputs are approximations based on generalized physiological models. These estimates may not be accurate for all individuals. Individual results will vary based on factors including but not limited to genetics, fitness level, medical conditions, medications, hydration, sleep, and environmental conditions. The Developer makes no representations or warranties regarding the accuracy, reliability, or completeness of any information provided by the App.

3.5 Stop If Symptomatic

If you experience faintness, dizziness, chest pain, nausea, shortness of breath, or any other unusual symptoms at any time while exercising, you should stop immediately and consult a medical professional. If you believe you are experiencing a medical emergency, call 911 (or your local emergency number) immediately.

3.6 Developments in Research

Developments in medical and exercise science research may impact the accuracy of the fitness information provided by the App. No assurance can be given that the App will always reflect the most recent findings or developments.

4. User Responsibilities

You are solely responsible for your use of the App and any physical activity you undertake in connection with it. You agree to:

  2. Monitor your own physical condition during any workout and stop exercising if you feel unwell.
  3. Use the App’s suggestions as one input among many—including your own judgment, your physician’s advice, and your awareness of your own body and limitations—when making decisions about physical activity.
  4. Take appropriate precautions while exercising, including monitoring your surroundings, staying hydrated, and not exceeding your capabilities.

5. Intellectual Property
