Terms of Use

These terms apply to your use of the STRONG app, operated by lab1.bio ("we"). By using the app you agree to them.

Health first

STRONG provides general strength training guidance. It is not medical advice. Talk to a doctor before starting a new exercise program, especially if you are pregnant, injured or have a health condition. Stop exercising if you feel pain, dizziness or shortness of breath. You train at your own risk.

Subscription

STRONG requires a subscription (monthly or yearly). Payment is charged to your Apple ID or Google account when you confirm the purchase. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. You can manage or cancel it in your App Store or Google Play account settings. Free trials, where offered, convert to a paid subscription unless cancelled before they end. Refunds are handled by Apple or Google under their policies.

Progress promise

If you train with your STRONG program for 8 weeks and see no progress in your logged lifts, contact support@strong-app.com and we will give you 3 months of STRONG for free.

Your account

Keep your sign-in secure and use the app only for personal, lawful purposes. Do not misuse the app or try to access other users' data.

Content

The programs, texts, images and software in the app belong to us or our licensors. You may use them only within the app for your own training.

Liability

We provide the app as is. To the extent the law allows, we are not liable for indirect damages or for injuries resulting from exercise. Nothing in these terms limits rights you have under mandatory consumer law.

Changes and contact

We may update these terms and will notify you of important changes in the app. Questions: support@strong-app.com.
