Terms of Service
Last updated: March 27, 2026
These Terms of Service ("Terms") govern your use of the Anvil mobile application ("App") operated by Stronger Software LLC ("we," "us," or "our"). By downloading, installing, or using the App, you agree to be bound by these Terms.
1. Description of Service
Anvil is a lifestyle optimization tool that helps users track daily habits, scan food and products, and receive a research-backed Optimization Score and testosterone estimate based on modifiable lifestyle factors.
Anvil is not a medical device. The App does not diagnose, treat, cure, or prevent any disease or medical condition. Testosterone estimates provided by the App are educational estimates based on published research and user-reported lifestyle data — they are not clinical measurements and should not be interpreted as medical diagnoses.
2. Health Disclaimer
Always consult a qualified healthcare provider before making health decisions. The information provided by Anvil is for educational and informational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment.
- Testosterone estimates are based on lifestyle factors and published studies, not clinical blood tests
- The Optimization Score reflects modifiable lifestyle behaviors only — it does not account for genetics, medications, or medical conditions unless explicitly disclosed
- AI-generated scan results (food analysis, body composition, product assessments) are estimates and may not be perfectly accurate
- Bloodwork calibration improves estimate accuracy but does not constitute medical analysis of your lab results
- Never disregard professional medical advice or delay seeking it because of information from this App
3. Eligibility
You must be at least 18 years old to use Anvil. By using the App, you represent and warrant that you are at least 18 years of age. If we learn that a user is under 18, we will terminate their account and delete their data.
4. Account Registration
To access the full features of Anvil, you must create an account using Apple Sign-In, Google Sign-In, or email/password. You are responsible for:
- Maintaining the security of your account credentials
- All activity that occurs under your account
- Notifying us promptly if you suspect unauthorized access
5. Subscriptions and Payments
Auto-Renewable Subscriptions
Anvil offers auto-renewable subscription plans. By subscribing, you agree to the following:
- Payment is charged to your Apple ID account at confirmation of purchase
- Renewal: Your subscription automatically renews unless you cancel at least 24 hours before the end of the current billing period
- Price changes: Subscription prices may change. You will be notified in advance of any price increase and must agree to it before renewal

Managing Your Subscription
You can manage or cancel your subscription at any time through your device's Settings > [Your Name] > Subscriptions > Anvil. Cancellation takes effect at the end of the current billing period — you retain access until then.
