Terms of Use

The short version

Compound is a training and food-logging tool, not medical advice. Its weights, plans and nutrition numbers are estimates, some written by AI, and you check them. Lifting carries a risk of injury that you accept. If we ever disagree, we try to sort it out by email first; if that fails, it goes to individual arbitration in Nevada, not to a class action or a jury, unless you opt out within 30 days (see Disputes). The rest of this page is the detail, and it is what applies.

Who this is between

These terms are an agreement between you and Stewart Christensen, who operates Compound (“Compound”, “we”, “us”). Compound is being moved into a Nevada limited liability company. When that company is formed, it takes over this agreement and these terms continue with it. Using the app or the website means you accept them, and the privacy policy, which is part of them. If you do not accept them, do not use Compound, and delete your account in the app.

Not medical advice

Compound suggests sets, reps and weights, and estimates what you eat. It is not a doctor, physiotherapist, dietitian or personal trainer, does not create any professional relationship with you, and nothing in it is a diagnosis, treatment or medical opinion. It does not know your medical history. Injuries you enter are used only to leave movements out of a plan.

Talk to a qualified professional before starting or changing how you train or eat, especially if you are pregnant or breastfeeding, take medication, are recovering from an injury or illness, or manage a condition such as diabetes or heart disease. Compound is not designed for anyone with, or recovering from, an eating disorder. It does not check food for allergens or interactions with medication.

Stop right away if you feel pain, dizziness, faintness or shortness of breath, and get medical help if you need it.

You take on the risk of training

Strength training and changing how you eat carry real risks, including injury and, rarely, serious harm. You choose what you lift, how you lift it and what you eat, and you take those risks on yourself. Use equipment you know how to use, warm up, and use a spotter or safety equipment where it makes sense.

Estimates and AI

Opening weights come from what you have lifted before. Calorie and macronutrient targets come from your height, weight, age and goal with a standard equation. Meals read from a photo, a label or a description, workouts and plans you ask for, custom movements, and the trainer notes on Today are written by an AI model. Barcode numbers come from public food databases (USDA FoodData Central and Open Food Facts) that can be wrong.

All of these can be incomplete, inaccurate or unsuitable for you. They are a starting point, not an answer: check them, and change anything that looks wrong. Every number in the app can be typed over. We do not guarantee the accuracy of any estimate, AI output or database entry, and you rely on them at your own risk.

Your account

You need an account so your training follows you between devices. Give accurate details, keep your password to yourself, and tell us if you think someone else has used it. Anything done with your account is treated as done by you. One account is for one person.

You must be at least 13 to have an account. If you are under 18, you may use Compound only with the knowledge and permission of a parent or guardian, who agrees to these terms for you.

What you put in

What you log stays yours. You give us a limited, non-exclusive, worldwide, royalty-free permission to store, process and display it, and to send what is needed to the services that run the app (such as the AI model that reads a meal), only to run and improve Compound for you, as set out in the privacy policy. We do not sell it, publish it, or use your photos or logs to train anyone's AI model. The permission ends when you delete the content or your account, except for copies we must keep by law or that sit in backups until they cycle out.

Only upload what you have the right to, including photos, workout programs and movement descriptions. If you send feedback or ideas, we may use them without owing you anything.

Things you may not do

Do not use Compound to break the law or anyone else's rights; try to get into other people's accounts or data; probe, overload, scrape or work around the service or its limits; copy, resell or extract the app, its exercise library or its demonstration clips; reverse-engineer it except where the law allows; or use automated tools to access it, other than the Connected AI feature as it is meant to work.

What we put in

The app, its design, its exercise library and its demonstration clips are ours or licensed to us. We give you a personal, non-transferable, revocable licence to use them in the app for your own training. Everything else stays with us and our licensors.

Apple Health, Connected AI and other services

If you turn on Apple Health, Compound reads the workouts and body weight you allow and writes what you choose; Apple's terms govern Apple Health itself. Barcode lookups use USDA FoodData Central and Open Food Facts.

Connected AI lets an AI assistant you choose, such as Claude or ChatGPT, read and change your Compound data on your behalf. When you connect one, you authorise it to do so, and what that assistant does with your data after it leaves Compound is governed by its provider's terms and privacy policy, not ours. We are not responsible for what a connected assistant says or does, including changes it makes to your plan or log. You can disconnect it at any time in the app.

We do not control third-party services and are not responsible for their availability, accuracy or conduct.

Paid features

Compound is free while it is in beta: no subscription, no purchases, no advertising. If paid features arrive, they will be sold through Apple, and these points will apply:

Apple bills you and handles refunds under its own policies. Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before it ends, in your Apple account settings. A free trial, if offered, turns into a paid subscription unless you cancel before it ends. Deleting your Compound account does not cancel a subscription; cancel it with Apple. We will tell you before a price changes.

Beta

Compound is in beta. Features may change, break or be removed, and data loss is possible. Keep anything you would hate to lose somewhere else too.

No warranty

Compound is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, accuracy, non-infringement, and that the app will be uninterrupted, secure or free of errors.

Limits on liability

To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for lost data, profits or goodwill, arising from your use of Compound, even if we were told they were possible. Our total liability for any claim about Compound is limited to the greater of US $100 or what you paid us in the 12 months before the claim.

Nothing here limits liability that the law does not allow to be limited, such as for fraud, gross negligence or wilful misconduct. Some places do not allow some of these limits, and there they apply only as far as allowed.

Indemnity

You agree to cover us, and our owners, contractors and partners, against claims, losses and reasonable legal costs arising from your breach of these terms, your misuse of Compound, or content you put into it that infringes someone else's rights.

Ending it

You can stop at any time by deleting your account in the app. We may suspend or close an account that breaks these terms, attacks the service or other people, or that we must close by law; where we reasonably can, we will tell you at the address on the account first. We may also change or stop offering Compound, and will give reasonable notice if we shut it down. The sections on medical advice, risk, estimates, warranty, liability, indemnity and disputes survive the end of this agreement.

Changes to these terms

If these terms change, the date at the top changes with them. For changes that materially affect you, we will tell you in the app or by email at least 30 days before they take effect. Using Compound after that means you accept the new terms. Changes never apply to a dispute already started.

Disputes

Talk first. Before any formal claim, email stewart@growthengines.us with your name, the address on your account, what happened and what you want. We will do the same with you. Both of us agree to try in good faith to settle it within 30 days.

Arbitration. If it is not settled, you and we agree that any dispute about Compound or these terms will be decided by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, not in court. The Federal Arbitration Act governs this section. The arbitration may be held by video or phone, or in person in Clark County, Nevada or the county where you live. Fees follow the AAA Consumer Rules.

Exceptions. Either of us may bring an individual claim in small claims court instead, and either of us may ask a court to stop someone infringing intellectual property or misusing the service.

No class actions, no jury. Claims may be brought only individually, not as a plaintiff or class member in a class, collective or representative action, and you and we each give up the right to a jury trial. If 25 or more similar claims are filed by the same or coordinated counsel, they will be handled in batches of up to 25, with the rest paused until each batch is decided.

Opting out. You can opt out of arbitration by emailing stewart@growthengines.us within 30 days of first accepting these terms, from the address on your account, saying you opt out. Opting out does not change anything else here.

Time limit. To the extent the law allows, a claim must be brought within one year of when it arose.

Governing law and courts

These terms are governed by the laws of the State of Nevada, United States, without regard to its conflict-of-law rules, and by the Federal Arbitration Act. Anything that is not arbitrated will be decided only by the state or federal courts located in Clark County, Nevada, and you and we agree to their jurisdiction.

Apple

These terms are between you and us, not Apple. We, not Apple, are responsible for Compound and its content, for maintenance and support, and for any product claim, including that it fails to meet a legal or regulatory requirement or infringes someone's rights. If Compound fails to meet a warranty that cannot be disclaimed, you may tell Apple, who will refund the price you paid (if any); Apple has no other warranty obligation. You confirm you are not in a country under a US embargo or on a US prohibited-parties list. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

The rest

These terms and the privacy policy are the whole agreement about Compound. If part of them cannot be enforced, the rest still applies. Not enforcing something now does not waive it. You may not transfer this agreement; we may transfer it, including to the Nevada company that will operate Compound or to a buyer of it.
