These Terms of Service ("Terms") govern your use of the NEPSYN mobile application ("App") and related services. By using NEPSYN, you agree to these Terms.
To use NEPSYN, you must create an account with a valid email address or sign in with Google. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. You must be at least 13 years old to use NEPSYN.
NEPSYN is a subscription-based service. After a 14-day free trial, a paid subscription is required to continue using the app.
Prices are in USD and may vary by region. Subscriptions are billed through the Google Play Store or Apple App Store. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current billing period. You can manage or cancel your subscription through your device's app store settings.
We reserve the right to change pricing with reasonable notice. Price changes will not affect your current billing period.
New users receive a 14-day free trial with full access to all features. If you do not subscribe before the trial ends, you will not be charged, but you will lose access to the app's features until you subscribe. Your data will be retained and available when you subscribe.
NEPSYN is a fitness tracking and planning tool, not a medical device or service. All metrics provided by the app — including strength scores, recovery readiness scores, BMI calculations, macro recommendations, and AI coaching suggestions — are for informational and educational purposes only. They do not constitute medical, nutritional, or professional health advice.
Consult a qualified healthcare professional before starting any exercise program, making dietary changes, or if you have concerns about your health. If you experience pain, dizziness, or other symptoms during exercise, stop immediately and seek medical attention.
NEPSYN includes AI-powered features (program generation, coaching chat, exercise suggestions, and photo analysis) powered by third-party AI services. AI-generated content is provided as suggestions and should not be treated as professional training or medical advice. AI features may occasionally produce inaccurate or incomplete information. You are responsible for evaluating and applying any AI suggestions at your own discretion.
You retain ownership of all content you create or upload to NEPSYN, including custom exercises, workout templates, programs, progress photos, and nutrition logs. By using the app, you grant us a limited license to store, process, and display your content solely to provide the service to you.
You are responsible for ensuring that content you upload does not violate any laws or third-party rights.
You agree not to:
You may delete your account at any time through the app. We may suspend or terminate accounts that violate these Terms. Upon termination, your data will be deleted in accordance with our Privacy Policy.
NEPSYN allows you to import workout data from other fitness apps (Strong, Hevy, Fitbod) via CSV/JSON files. You are responsible for ensuring you have the right to export and import this data. We are not affiliated with these third-party apps.
NEPSYN is provided "as is" without warranties of any kind, express or implied. We do not guarantee that the app will be uninterrupted, error-free, or that all data will be preserved in every circumstance. To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the app.
Our total liability for any claim related to the service shall not exceed the amount you paid for the service in the 12 months preceding the claim.
We may update these Terms from time to time. We will notify you of material changes through the app or by email. Continued use of the app after changes constitutes acceptance of the updated Terms.
These Terms are governed by the laws of the United States. Any disputes shall be resolved in the courts of the State of Michigan.
