Terms of Service

Last updated: July 22, 2026

1. Acceptance of Terms

By creating an account or using Ratio Fitness (the "App"), you agree to these Terms of Service. If you do not agree, please do not use the App.

2. Description of Service

Ratio Fitness is a nutrition and fitness tracking application that helps you log meals, track macros, monitor body measurements, plan workouts, and receive AI-generated meal and coaching suggestions. Some features may be offered as paid subscriptions in the future; any such features will be clearly identified before you're charged.

3. Eligibility

You must be at least 16 years old to create an account. By using the App, you confirm that you meet this requirement.

4. Your Account

You're responsible for maintaining the confidentiality of your login credentials and for all activity under your account. Let us know right away if you suspect unauthorized access to your account.

5. Health & Fitness Disclaimer

Ratio Fitness provides general fitness and nutrition information for informational purposes only. It is not medical advice, and it is not a substitute for consultation with a physician, registered dietitian, or other qualified health provider. Always consult a doctor before starting a new diet or exercise program, especially if you have an existing health condition. Calorie, macro, and other targets generated by the App are estimates and may not be appropriate for every individual.

6. Subscriptions & Payments

Certain features (such as AI Coach) may require a paid subscription. Prices, billing terms, and cancellation policies will be presented clearly at the time of purchase. Subscriptions renew automatically unless cancelled in accordance with the applicable app store's policies.

7. User Content

You retain ownership of any photos, meal entries, or other content you upload to the App ("User Content"). By uploading User Content, you grant us a limited license to store and display it back to you as part of the Service. We do not claim ownership of your photos or personal data.

8. Acceptable Use

You agree not to misuse the App, including attempting to access other users' data, reverse-engineer the App, or use the Service for any unlawful purpose.

9. Third-Party Services

The App uses third-party services to operate certain features, including cloud data storage and AI providers that power meal suggestions and coaching responses. These providers process data solely to deliver the App's functionality.

10. Intellectual Property

The App, including its design, branding, and underlying code, is owned by Ratio Fitness and protected by applicable intellectual property laws. You may not copy, modify, or distribute any part of the App without permission.

11. Termination

You may stop using the App and delete your account at any time. We may suspend or terminate accounts that violate these Terms.

12. Disclaimers & Limitation of Liability

The App is provided "as is" without warranties of any kind. To the fullest extent permitted by law, Ratio Fitness is not liable for any indirect, incidental, or consequential damages arising from your use of the App.

13. Changes to These Terms

We may update these Terms from time to time. Continued use of the App after changes take effect constitutes acceptance of the updated Terms.

14. Governing Law

These Terms are governed by the laws of the State of Texas, without regard to conflict of law principles.

Privacy Policy

Last updated: July 22, 2026

1. Introduction

This Privacy Policy explains what information Ratio Fitness collects, how we use it, and the choices you have. We built this App to help you reach your health goals, and we take handling your personal and health data seriously.

2. Information We Collect

We collect information you provide directly, including your name, email, username, height, age, sex, and activity level; nutrition and workout data you log (meals, macros, exercises); body measurements and progress photos you choose to upload; and messages you send to the AI Coach.

3. How We Use Your Information

We use your information to operate the App's core features — calculating your nutrition targets, displaying your progress, generating meal and workout suggestions, and personalizing your experience. We do not sell your personal information to third parties.

4. AI-Powered Features

Features like meal suggestions and AI Coach responses are powered by third-party AI providers. Relevant details you provide (such as your goals, allergies, or a question you ask) are sent to these providers solely to generate a response, in accordance with their own data handling terms.

5. Photos & Camera Access

If you choose to use progress photos, meal scanning, or barcode scanning, the App will request camera and/or photo library permission. Photos you upload are stored securely and are only visible to you. You can delete any photo at any time within the App.

6. How We Store & Protect Your Data

Your data is stored with reputable cloud infrastructure providers using industry-standard security practices, including encryption in transit. While no system can guarantee absolute security, we work to protect your information from unauthorized access.

7. Data Sharing & Third Parties

We share data only as needed to operate the App — for example, with our cloud database and AI providers described above. We do not sell or rent your personal data to advertisers or data brokers.

8. Your Rights & Choices

You can access, correct, or delete most of your data directly within the App. You may request a copy of your data or full account deletion by contacting us at the email below.

9. Children's Privacy

Ratio Fitness is not directed to children under 16, and we do not knowingly collect personal information from children under that age.

10. Data Retention

We retain your data for as long as your account is active. If you delete your account, we will delete or anonymize your personal data, except where retention is required by law.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We'll let you know of material changes within the App.

12. Contact Us

    Estimate Body Fat %
    Uses the U.S. Navy tape method — more accurate than BMI alone
    Measure in inches with a soft tape. Neck: below larynx. Waist: at navel (men) or narrowest point (women). Hips: widest point (women only).
    Neck (inches)
    Waist (inches)
    Hips (inches) — women only
    Uses your height, weight, age, and sex from your Profile. Accuracy is ±3–5% — good enough to get started, but the Navy method is more reliable.
    Make sure your Profile is up to date for best results.
