Version 2.1

Terms of Service

The agreement between you and Cam Lab covering the Motion website and the MotionX app.

Effective September 15, 2026Last updated September 24, 2026

In short

You need to be 16 or older to sign up yourself. Younger athletes can only be added by a club, and only if the club holds a parent's consent.
Your videos stay yours. You give us permission to process and store them so the Service can work.
We may use de-identified skeletal data — joint positions and angles, with your name and your footage stripped out — to improve our analysis models. You can turn this off at any time in Settings.
Motion analysis is not medical advice. Training carries a real risk of injury, and you take that risk on yourself.
Disputes are handled by individual arbitration, not class actions, and our financial liability is capped.

A plain-language summary, for orientation only. The numbered sections below are what actually applies.

These Terms of Service (the "Terms") are a binding agreement between you and Cam Lab ("Cam Lab", "we", "us", or "our"), the operator of the Motion platform. The Service is currently operated by an individual sole proprietor trading as Cam Lab; if that changes, these Terms transfer to the successor entity as described in the General section.

"Service" means the Motion web application at motion.cam-lab.org, the MotionX iOS application, our public pages, shared links, event leaderboards, APIs, and any other software or content we make available under the Cam Lab or MotionX names.

By creating an account, signing in, or otherwise using the Service, you confirm that you have read these Terms and agree to be bound by them, together with our Privacy Policy, which is incorporated here by reference. If you do not agree, do not use the Service.

Your controls in Motion

Everything this policy says you can change lives in Settings. None of it needs an email to us first, unless a row says so.

01Eligibility and age

You must be at least 16 years old and able to enter into a binding contract to create an account for yourself. By registering, you represent that you meet both requirements.

Athletes under 16 may take part only through a club. A club administrator or coach may add an athlete under 16 to their roster, upload footage of them, and receive analysis about them. By doing so, the club represents and warrants to us that it has obtained verifiable consent from that athlete's parent or legal guardian, that it holds any consent its own institution or governing body requires, and that it will withdraw the athlete from the Service promptly on request. The club, not Cam Lab, is responsible for obtaining and evidencing that consent.

Data belonging to an athlete a club has identified as under 16 is excluded from model training entirely, regardless of any account-level setting.

If we learn that someone under 16 created an account without a club, or that a club added a minor without the consent it warranted it had, we will suspend the account and delete the associated data.

02Your account

Give accurate information when you register, and keep it current. An email address or phone number you do not control is not a valid credential.
Keep your password and any sign-in codes confidential. You are responsible for everything that happens under your account, whether or not you authorised it.
Tell us promptly at support@cam-lab.org if you believe someone else has access to your account. We can sign every device out on request.

06Improving our models with de-identified motion data

This is the clause people most often want to check, so it is written plainly: we may learn from the SHAPE of your movement, not from you. Skeletal data — the coordinates of joints over time, and the angles and timings computed from them — may be used to train and improve our pose, grading and coaching models. You can turn this off in one tap, and it is off for every athlete a club has identified as under 16.

What we may use.: The estimated positions of your joints over time, and the measurements worked out from them: joint angles, stroke and stride timings, phases of the movement, quality scores, the sport and how the clip was filmed, and the resulting grade. This data is separated from your account before it is used for training and is not labelled with your name, email, phone number, club, or account identifier.
What we do not use.: We do not train on your raw video or images, on frames of your face or body, on your profile, injury notes, goals, messages, or coach comments, and we do not use your motion data to identify you or to try to recognise you in other footage. We do not sell training data, and we do not give it to anyone else to train their models.
How to opt out.: Settings → Data & Privacy on the web, or Settings → Privacy & security in MotionX. Turning it off stops any future use of your data for training, including data already stored. You can also email support@cam-lab.org and we will do it for you.
What opting out cannot undo.: A model that has already been trained cannot have one athlete's contribution subtracted from it — the data does not survive inside it in a retrievable form. Opting out therefore stops future training runs from using your data; it does not require us to discard models trained before you opted out. This is a real limit, and we would rather state it than imply a deletion we cannot perform.
Who is excluded automatically.: Athletes a club has identified as under 16, and anyone whose account was created in a jurisdiction where we cannot rely on this basis, are excluded regardless of the setting.

Improvements produced this way belong to us. Nothing in this section gives you a claim to a model, a score, or any revenue from either — and nothing in it gives us any right over Your Content beyond what is described above.

17Governing law and dispute resolution

Please read this section carefully. It requires most disputes to be resolved by individual arbitration rather than in court, and it waives your right to a jury and to participate in a class action. You may opt out of arbitration within 30 days.

These Terms are governed by the laws of the State of Delaware, United States, without regard to its conflict-of-laws rules, and excluding the United Nations Convention on Contracts for the International Sale of Goods. If you are a consumer resident in the EU, the UK, or another jurisdiction whose law gives you the protection of mandatory local rules, those rules continue to apply to you and this choice of law does not take them away.

Talk to us first.: Before starting formal proceedings, send a written description of the dispute and the relief you want to support@cam-lab.org. We will do the same. Most things are resolved this way, and both of us agree to try in good faith for 30 days before going further.
Arbitration.: If that fails, any dispute arising out of or relating to these Terms or the Service will be resolved by final and binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules. The arbitration will be conducted in English, by a single arbitrator, remotely or in the county where you live unless we both agree otherwise. The arbitrator decides all issues except those reserved to a court below.
Small claims and injunctions.: Either of us may bring an individual claim in small-claims court if it qualifies, and either of us may ask a court for an injunction to stop misuse of intellectual property or unauthorised access. Doing either is not a waiver of this section.
No class actions.: Claims must be brought individually. Neither of us may bring a class, collective, consolidated or representative action, and the arbitrator may not consolidate claims or preside over any form of representative proceeding. If this waiver is held unenforceable for a particular claim, that claim — and only that claim — proceeds in court.
Jury waiver.: If for any reason a dispute proceeds in court rather than arbitration, both of us waive any right to a jury trial.
Time limit.: Any claim must be brought within one year after it arises, or it is permanently barred, unless the law where you live forbids shortening the limitation period.
Opting out of arbitration.: You may opt out by emailing support@cam-lab.org with the subject "Arbitration opt-out", from the address on your account, within 30 days of first accepting these Terms. Opting out costs you nothing and changes nothing else in this agreement.

Where local law gives you the right to bring proceedings in your own courts — as it does for consumers in the EU and the UK — this section does not remove that right, and the arbitration requirement applies only to the extent the law where you live permits it.
