Terms of Service

1. Who you're agreeing with

"Stupid Simple Fitness," "we," "us," and "our" mean Linchpin Industries, the company that operates the Stupid Simple Fitness service (the "Service"), reachable at help@stupidsimplefitness.com. "You" means the person using the Service.

By creating an account, starting a free trial, or otherwise using the Service, you agree to these Terms of Service (the "Terms"), our Privacy Policy, our Medical Disclaimer, and our AI Disclosure. If you don't agree, don't use the Service.

2. Eligibility

You need to be at least 18 years old to use the Service. The Service is built for adults making decisions about their own bodies and their own training. We do not knowingly collect information from anyone under 18. If you're a parent or guardian and you think your kid has signed up, email us and we'll delete the account.

You also need to be physically capable of safely doing exercise. If you have any condition, injury, pregnancy, post-surgical recovery, medication, or other circumstance that makes exercise risky, talk to a qualified healthcare professional before you use any plan we generate. See the Medical Disclaimer for the long form on this.

3. Your account

You're responsible for keeping your login credentials secure and for everything that happens under your account. If you think someone else has access to your account, tell us and change your password.

Keep the information you give us reasonably accurate. The Service builds plans from what you tell it. Lying to it about your goals, your injuries, your training history, or your weight is a great way to get a plan that doesn't fit you, and we can't fix what we can't see.

4. The trial, the price, and the billing

Free trial

New accounts get a 14-day free trial. We do not collect a payment method to start the trial. On day 14 we will ask you to add one if you want to keep using the Service.

Subscription

After the trial, the Service is paid:

• Monthly: $5.00 USD per month, billed monthly until cancelled.
• Annual: $49.00 USD per year, billed once per year until cancelled.

Prices are in U.S. dollars and exclude any taxes that may apply where you live. Your payment is processed by our payment processor (currently Stripe). We don't see or store your full card number.

Renewals

Subscriptions renew automatically at the end of each billing period using the payment method on file. We will not surprise you with a price increase. If we change pricing, we will tell you in advance and your existing subscription will keep its existing price for at least the next billing cycle.

Cancelling

You can cancel anytime from your subscription page. There is no retention call, no "are you sure" gauntlet, no hidden steps. When you cancel, you keep access through the end of the period you've already paid for, and you are not billed again.

Refunds

Because the trial gives you 14 days to decide, we don't offer refunds for partial billing periods after that. If something legitimately broke on our end (we charged you twice, the Service was unusable, billing fired in error), email us and we'll make it right. We're humans, not a refund-denial chatbot.

5. What you can and can't do with the Service

Use the Service for your own personal, non-commercial fitness planning. That's it. That's the whole intended use case.

You may not:

• Resell, sublicense, or repackage the Service or its outputs as a product.
• Scrape, mirror, or systematically extract content from the Service.
• Use the Service to train or fine-tune a competing AI product.
• Reverse engineer, decompile, or attempt to extract our system prompts or model configuration.
• Attempt to break our safety rails by jailbreaking, prompt injection, or impersonating staff. We log this. We will revoke your account.
• Use the Service to harm yourself or anyone else, or to plan training that you have been medically advised against.
• Use the Service in any way that violates law, infringes someone else's rights, or interferes with the Service's normal operation.

6. The AI part

The Service uses AI to generate workout plans, recalibrate them based on your logged training, and produce written feedback. The AI is not a doctor, dietitian, physical therapist, or personal trainer, and we do not pretend it is. It will sometimes be wrong. It is configured to refuse plans that look unsafe and to push back on goals that don't math. See the AI Disclosure for the full picture of what the AI does, where it can fail, and what we do about it.

You are the human in the loop. You are the one deciding whether a given workout makes sense for your body on a given day. If the plan tells you to do something that hurts, stop.

7. Your content

"Your Content" means the goals, history, logs, journal entries, and other inputs you give the Service.

You own Your Content. We need a limited license to use it for the purpose of running the Service for you: storing it, processing it through the AI, generating plans and reports from it, and showing it back to you. That license ends when you delete the content or close your account, except for backups that age out on a normal schedule and any data we are legally required to keep.

We do not sell Your Content. We do not use Your Content to train third-party AI models. We do not share Your Content with advertisers. The full breakdown of what we do and don't do with your data lives in the Privacy Policy.

8. Our content

The Service itself, including the brand, the visual design, the system prompts, the source code, and the written copy, belongs to us or our licensors. The plans the AI generates for you are yours to use for your own training; the underlying templates, prompt design, and software are not.

9. Service changes and availability

We will keep working on the Service. That means features will change, get added, and occasionally get removed when they're not pulling their weight. We will not change the core product loop in a way that makes it unrecognizable without telling you.

The Service is provided on an "as available" basis. We aim for high uptime but we don't promise 100%. If something major breaks, we'll communicate.

10. Termination

You can close your account anytime from the subscription page or by emailing us.

We can suspend or terminate your account if you violate these Terms, abuse the Service, attempt to circumvent our safety rails, or do something that puts us, our other users, or our infrastructure at risk. In serious cases (fraud, abuse, attempted compromise) we may do this without notice. In ordinary cases we will tell you what's wrong and give you a chance to fix it.

On termination, your access ends. We will delete or anonymize your data on the schedule described in the Privacy Policy.

11. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, to the maximum extent permitted by law. We do not warrant that the Service will be uninterrupted, error-free, or that the AI's outputs will be accurate, safe, or appropriate for your specific situation.

Nothing in the Service is medical advice. Nothing in the Service is a substitute for evaluation by a qualified healthcare professional. See the Medical Disclaimer.

12. Limitation of liability

To the maximum extent permitted by law, Linchpin Industries and its officers, employees, and contractors will not be liable for any indirect, incidental, consequential, special, or punitive damages, or for lost profits, lost data, or loss of goodwill, arising out of or related to your use of the Service.

Our total liability for any claim arising out of or related to the Service is limited to the greater of (a) the amount you paid us in the 12 months before the claim arose, or (b) one hundred U.S. dollars ($100.00).

Some jurisdictions don't allow these limitations. If you live in one, the limitations apply to the maximum extent allowed where you live.

13. Indemnification

You agree to indemnify and hold harmless Linchpin Industries from any claim, demand, loss, or expense (including reasonable attorneys' fees) arising out of (a) your violation of these Terms, (b) your misuse of the Service, or (c) your violation of any law or third-party right.

14. Governing law and disputes

These Terms are governed by the laws of the State of California, without regard to its conflict of laws rules. Any dispute arising out of or related to the Service or these Terms will be brought in the state or federal courts located in Orange County, California, and you and we both consent to that jurisdiction.

15. Changes to these Terms

We may update these Terms when the Service changes, when the law changes, or when we screw something up and need to fix the wording. If a change is material, we will notify you (in-app, by email, or both) before it takes effect. Continuing to use the Service after the change means you accept the new Terms. If you don't, cancel.

16. Miscellaneous

These Terms, together with the policies linked from them, are the entire agreement between you and us about the Service. If a court finds any part unenforceable, the rest stays in force. Our failure to enforce a provision now does not waive our right to enforce it later. You may not assign these Terms; we may assign them to a successor (for example, in connection with a sale of the business).
