Terms of Use

Effective September 27, 2026

These terms are an agreement between you and Lightning Studio LLC ("we", "us"), which makes No Pain No Gain ("the app"). By using the app you accept them.

1. Health first

The app gives general fitness information, not medical advice. Talk to a doctor before starting a new exercise program, especially if you have a health condition, an injury, or are pregnant. Stop exercising if you feel pain, dizziness or shortness of breath. You train at your own risk.

2. AI features

AI-generated plans and replies can be wrong. Check them against your own judgment and professional advice. Don't use them to diagnose or treat injuries.

3. Your account

You can use the app without an account. If you create one, keep your sign-in method secure. You can delete your account at any time in the app or at /delete-account.

4. Pro subscriptions

• Pro is billed monthly or yearly through your Apple ID or Google Play account and renews automatically unless cancelled at least 24 hours before the end of the current period.
• A free trial, if offered, converts to a paid subscription when it ends unless you cancel before then.
• Manage or cancel in your App Store or Google Play subscription settings. Deleting the app or your account does not cancel a subscription.
• Refunds are handled by Apple or Google under their policies.
• Lifetime Pro is a one-time purchase for the life of the app on your account.

5. Sparks and Pro Passes

Sparks are an in-app currency for AI features and cosmetic items. They have no cash value, can't be transferred or exchanged for money, and purchased Sparks don't expire. Sparks included with Pro each month expire at the end of that month. A Pro Pass earned by watching ads gives Pro features for the stated time and has limits per week. We may change Spark prices for future spending; spent Sparks are not refunded unless an AI request fails.

6. Acceptable use

Don't misuse the service: no reverse engineering to bypass payments, no automated abuse of AI features, no attempts to access other users' data.

7. Content and licenses

The app, its exercise instructions and programs belong to Lightning Studio LLC. Open-source software in the app is used under its own licenses, listed in the app under Settings → Licenses. Exercise illustrations are licensed from RepDB (exercise data by RepDB, repdb.co). Some exercises show demonstration videos made by their YouTube creators, played in YouTube's embedded player; those videos belong to their creators. You keep ownership of the data you enter and give us permission to store and process it to provide the service.

YouTube. Exercise videos use YouTube API Services. By watching them in the app you agree to be bound by the YouTube Terms of Service.

8. Availability and changes

Features may change. Core logging keeps working offline on your device. We will post changes to these terms here.

9. Liability

The app is provided "as is". To the extent the law allows, we are not liable for injuries, losses or damages arising from your use of the app or its content, and our total liability is limited to the amount you paid us in the 12 months before the claim.
