Terms of Service

Who we are

The service is operated by Core Motion. You can reach us at support@core-motion.app, and we answer at that address about anything in these terms.

This is not medical advice

Core Motion is a fitness tool, not a medical device and not a doctor. Nothing it shows you — a suggested weight, a calorie target, a comment from the AI coach — is a diagnosis, a treatment, or personalised medical advice.

Strength training carries a real risk of injury. You decide what you lift. Before starting a programme, and especially if you are pregnant, recovering from an injury, or have a heart, joint or metabolic condition, talk to a qualified professional. Stop and seek help if something hurts.

The training limitations you tell us about make the plan avoid certain movements. That is a convenience, not a safety guarantee: we cannot see your technique, your equipment, or how you feel today.

Your account

You need an account to use the service, and you must be at least 16 years old. Keep your password to yourself — anything done from your account is treated as done by you. Tell us at once if you think somebody else has access to it.

One account is one person. Sharing an account defeats the entire point: every weight the app suggests is computed from the history it has, and two people training on one account produce a plan that fits neither.

What the AI coach is, and what it is not

The numbers in your plan — the loads, the rest, the progression — are produced by a deterministic engine, not by a language model. The AI explains, comments, drafts a programme from your description, estimates the calories in a photo of a meal and answers questions in chat.

The AI can be wrong. It is asked never to invent a fact about your training, and it does not decide the weights, but its text is generated and may still be inaccurate. Treat it as a knowledgeable training partner, not as an authority — and never as a substitute for professional advice.

AI features are optional and best-effort. If a model is unavailable, the app falls back to its deterministic behaviour and keeps working; there is no promise that any particular AI answer is available at any particular moment.

Fair use and limits

Every account has a limit on how much AI it may use, because each request costs us real money. The limits belong to the plan the account is on, they are visible when you reach one, and we may change them. If a limit is in your way, write to us — it is one line for us to raise.

Do not use the service to break the law, to harass anyone, to attack the infrastructure, to scrape it in bulk, or to resell access to it. Do not try to get around the AI limits with multiple accounts.

Payment

The service is currently free to use. If paid plans are introduced, you will be told the price and what it includes before anything is charged, and using a paid plan will be a separate choice, not a change that happens to an account by itself.

Your content

Your training data, your photos, your notes and your chat messages remain yours. You give us only the permission needed to run the service for you: to store that data, to show it back to you, and to send the relevant parts to the AI providers named in the Privacy Policy so the coaching features can work.

We do not sell your data and we do not use your training data to train AI models.

Ending it

You can delete your account at any time, from your profile. The account is disabled immediately and everything it owns is erased 30 days later; you can cancel within those 30 days by signing in again.

We may suspend or close an account that breaks these terms, is used to harm other people, or is used to attack the service. Where it is reasonable to do so, we will say why first.

What we do not promise

The service is provided as it is. We work to keep it available and correct, but we do not promise it will be uninterrupted, error-free, or that any particular result — a weight, a body composition, a personal record — will follow from using it. Results from training depend on you.

To the extent the law allows, we are not liable for indirect or consequential loss. Nothing here limits liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited by law.

Changes

We may update these terms. If a change matters to you — what we collect, what we charge, what we promise — we will tell you in the app before it takes effect. Continuing to use the service after that means you accept the new version.

Law

These terms are governed by the law of the country where the operator is established. If you are a consumer in the EU, this does not take away the protection of the mandatory rules of the country you live in.
