Terms of Service

Effective: June 1, 2026 · Last updated: June 1, 2026

1. Agreement to these Terms

These Terms of Service (the “Terms”) form a binding legal contract between you and Movement Theory Labs LLC, a Florida limited liability company (“Movement Theory,” “we,” “us,” or “our”). They govern your access to and use of the Movement Theory iOS app (the “App”), the website at movementtheory.app and its subdomains (the “Site”), and any related services we provide (collectively, the “Services”).

By downloading, installing, signing in to, or otherwise using the Services, you agree to these Terms and to our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the Services.

If you are using the Services on behalf of a child under 13, the parent or legal guardian agrees to these Terms on the child’s behalf and assumes responsibility for the child’s use. See Section 5 (Children and Parental Responsibility).

2. Eligibility and account

2.1 Age

You may create your own Movement Theory account if you are at least 13 years old. If you are between 13 and the age of legal majority in your jurisdiction (typically 18), your parent or legal guardian must review these Terms and agree to be bound by them on your behalf, and you and your parent are jointly responsible for your use of the Services.

If you are under 13, you may not create your own account. You may use the Services only through a profile that a parent or legal guardian has created and consented to inside their own Movement Theory parent account, in compliance with the U.S. Children’s Online Privacy Protection Act (COPPA).

2.2 Account creation

You may create an account using a valid email address and a password, or by using Sign In with Apple. You agree to:

You are responsible for all activity that occurs under your account, whether or not you authorized it, except to the extent caused by our breach of these Terms or applicable law.

2.3 One account per person

Each person may maintain one personal account at a time. A parent account may include up to four (4) child dancer profiles under the Premium Family plan, subject to the subscription terms below.

3. What the Services do

Movement Theory provides:

The Services are an educational and self-coaching aid. They do not replace, and are not intended to replace, qualified dance instruction, medical advice, physical therapy, registered dietitian guidance, or any other licensed professional service. See Section 8 (Disclaimers).

We may add, change, or remove features at any time. We will give you reasonable notice of material changes that affect a paid subscription tier.

Geographic availability. The Services are currently offered only in the United States and are intended for U.S. residents. We may make them available in other regions in the future.

4. AI features and your acknowledgments

4.1 What we send to AI providers

When you use the AI analysis feature, the App sends to our backend, which forwards to Anthropic’s Claude API, the pose metrics computed on your device (joint angles, alignment and symmetry scores), the move label you entered, and small amounts of calibration context (dance level, dance styles, any injury flag you have entered, and — only for a dancer under 12 — a coarse “young dancer” indicator; we do not send your exact age, date of birth, or name) — never the raw video, never an image of your face, and never your full landmark stream. When you scan a food barcode, the App queries the public Open Food Facts database; when you photograph an ingredient, the photo is sent to Claude to identify the product and serving information and is not retained after the request completes. Our Privacy Policy describes this in detail.

The App presents an in-App disclosure the first time you use any AI feature and asks for your explicit permission before sending data to our AI provider. You may withdraw your permission at any time in Profile → Privacy controls; doing so disables the AI features until you re-enable them.

4.3 No guarantee of accuracy

AI-generated feedback, scores, exercise recommendations, and nutrition information may be incomplete, inaccurate, or out of date. Treat them as one input among many, not as an authoritative judgment of your technique or your body’s needs. Do not rely on the Services for any decision that has medical, nutritional, or safety consequences without consulting a qualified professional. See Section 8.

4.4 Training

We do not use your inputs to train any AI model. We use Anthropic’s standard commercial API; Anthropic does not train its models on data submitted through the API, and Anthropic may retain operational data for up to 30 days before deleting it. See our Privacy Policy, Section 7, for details.

5. Children and parental responsibility

5.1 Parent-managed profiles

A dancer under 13 may use Movement Theory only through a profile inside a parent’s account, after the parent has completed our verifiable parental consent flow described in the Privacy Policy, Section 9. By creating a child profile, the parent or legal guardian:

5.2 Recording minors

When you (a parent or anyone else) record a video of a minor for analysis, you represent that you have the legal authority and any necessary consents to record that minor in the setting where the recording occurs (studio, home, competition, etc.). You will not upload or process video of any minor for whom you do not have such authority.

5.3 Family plan profiles

If you are on a Premium Family plan, only the account holder may manage child profiles. Each child profile is associated solely with the parent account that created it and cannot be transferred without our help.

6. Subscriptions, free tier, billing

6.1 Free tier

The Services include a free tier that provides three (3) full dance analyses per calendar month, basic workout content, the Education hub, performance-event tracking, and limited nutrition logging. We may change the free-tier offer with reasonable notice.

6.2 Subscription plans

Movement Theory offers the following auto-renewing subscriptions (the “Subscriptions”), shown on the in-App Paywall as:

Current prices, the length of each billing period, and any introductory trial are shown inside the App on the Paywall screen at the time of purchase. Prices may vary by country and are subject to applicable taxes. We may change prices on renewal with at least 30 days’ notice; you can cancel before the change takes effect.

6.3 Billing through Apple

All Subscriptions are billed by Apple Inc. through your Apple ID and the App Store. By subscribing:

6.4 Introductory offers and free trials

If we offer an introductory or free-trial period, the offer terms (length, eligibility, price after trial) are shown in the App at purchase. If you cancel before the trial ends, you will not be charged for the renewal that would follow. One free trial per Apple ID per plan, except where Apple’s rules allow otherwise.

6.5 Refunds

Refunds for App Store purchases are administered by Apple, not by us. Submit refund requests through https://reportaproblem.apple.com. We are not able to issue refunds for App Store transactions and do not control Apple’s refund decisions. If you believe a charge is in error, contact us at [email protected] and we will assist where we can.

6.6 Restoring purchases

You can restore prior purchases by tapping Profile → Subscription → Restore Purchases while signed into the Apple ID that made the purchase.

6.7 No Apple Family Sharing

Premium Family Annual does not use Apple Family Sharing. The plan is a single Movement Theory parent account that includes up to four (4) child dancer profiles inside the same account. Each child uses Movement Theory through the parent’s account; no additional Apple IDs are entitled by the subscription. We may enable Apple Family Sharing in the future and will update these Terms before doing so.

7. User content and license

7.1 Your content

“User Content” means any content you record, upload, type, save, or otherwise provide through the Services — including dance videos, audio captured during recording, profile information, dancer profiles, injury notes, recipes, meal entries, performance events, and any messages you send us.

You retain ownership of your User Content. Recordings you capture stay on your device unless you explicitly export them.

7.2 License to us

To the extent we need a license to operate the Services, you grant Movement Theory a worldwide, non-exclusive, royalty-free, revocable license to host, store, process, transmit, and display your User Content solely for the purpose of providing, maintaining, and improving the Services to you. This license ends when you delete the relevant User Content or close your account, except (i) for backups in our normal rotation (up to 90 days) and (ii) to the extent third-party service providers retain copies in their own backup systems on their normal rotations.

We do not use your User Content to train AI models or to develop new products that are not the Services. We do not publish, display, sell, or share your User Content outside the contexts described in the Privacy Policy.

7.3 Your representations

You represent and warrant that:

8. Disclaimers — health, training, and AI

Read this section. It limits the risks Movement Theory accepts for the kinds of decisions you make with our help.

8.1 Not medical advice

Movement Theory is a general wellness and education product, not a healthcare provider. The Services do not provide medical, diagnostic, therapeutic, mental-health, or rehabilitative services. Information about anatomy, biomechanics, injuries, nutrition, exercises, scoring, and dance technique is provided for educational and informational purposes only.

Always consult a qualified medical professional before starting any new training or dietary program, especially if you (or the dancer you are responsible for) have an injury, a history of disordered eating, a pregnancy, a chronic condition, or other relevant health considerations. Stop and seek professional help if anything you do based on the Services causes pain, dizziness, faintness, or unusual symptoms.

We do not diagnose injuries, prescribe treatment, recommend medications, or replace the care of a physician, physical therapist, athletic trainer, registered dietitian, sports psychologist, or any other licensed professional.

8.2 Not a substitute for instruction

The AI coaching notes, drill recommendations, and “next session focus” are designed to supplement training with a qualified dance instructor, not to replace one. They are based on numerical pose metrics that approximate, but do not capture, the full reality of your body and your technique.

8.3 Assumption of risk

Dance training involves inherent physical risks, including the risk of strain, sprain, fracture, joint injury, and other harm. By using the Services, you accept those risks and agree to use your own judgment, and (for a parent or guardian) to supervise the dancer for whom you are responsible. Do not attempt movements beyond your current ability, and do not perform any exercise the Services suggest without first ensuring you have appropriate space, footwear, supervision, and warm-up.

8.4 Award levels and scores are aspirational

Scores from 0–100 and award levels (High Silver, Gold, High Gold, Platinum, etc.) are internal Movement Theory rubrics generated by AI from pose metrics. They are not official competition scores, are not endorsed by any dance association or competition organizer, and have no value outside the App.

8.5 Nutrition feature limits

Macros, calorie targets, food-lookup results, and recipe data are estimates only. Nutritional information from Open Food Facts is community-contributed and may be inaccurate. AI-generated nutrition lookups may be wrong. Verify allergens, serving sizes, and ingredient lists from the actual product label. Consult a registered dietitian for personalized nutrition guidance, particularly for any dancer with a medical condition, a young or developing dancer, or anyone with disordered-eating history.

8.6 “AS IS”

To the maximum extent permitted by law, the Services are provided “AS IS” and “AS AVAILABLE,” without warranties of any kind, express or implied, including any warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, reliability, availability, uninterrupted operation, freedom from viruses or errors, or that defects will be corrected. Some jurisdictions do not allow the disclaimer of certain warranties, so portions of this paragraph may not apply to you.

9. Acceptable use

You agree not to:

We may suspend or terminate accounts that violate this section. See Section 13.

The Services rely on third-party services (Apple App Store, Apple Sign-In, Anthropic, Supabase, RevenueCat, Render, Open Food Facts, Resend, and Microsoft 365). Your use of those services is governed by their own terms and privacy policies. Movement Theory is not responsible for third-party services and does not endorse their content. Links from the App or the Site to third-party websites are provided for convenience; we are not responsible for their availability, content, or practices.

11. End User License Agreement (EULA)

11.1 License grant

We grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on Apple-branded devices that you own or control, and to access the Site, in each case in accordance with these Terms and the Apple Standard EULA (the “Standard EULA”) published at https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. To the extent these Terms and the Standard EULA conflict on a topic covered by the Standard EULA, the Standard EULA controls for the App; these Terms control on all other topics.

11.2 Apple acknowledgments

You and we acknowledge that these Terms are between you and Movement Theory, and not with Apple, and Apple is not responsible for the App or its content. Apple has no obligation to provide any maintenance and support services with respect to the App; Movement Theory, not Apple, is solely responsible for any maintenance and support for the App, and you may direct support questions to [email protected]. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price for the App to you (if any); to the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to the App. Apple is not responsible for addressing any claims by you or any third party relating to the App or your possession or use of the App, including product-liability claims, claims that the App fails to conform to any legal or regulatory requirement, claims arising under consumer-protection or similar legislation, and claims that the App infringes a third party’s intellectual property rights. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary of these Terms.

11.3 Export

You may not use the App in any country subject to U.S. embargo or that has been designated by the U.S. Government as a “terrorist supporting” country, and you may not be on any U.S. Government list of prohibited or restricted parties.

12. Intellectual property

The Services, including all software, text, graphics, audio, video, images, logos, the name “Movement Theory,” the wordmark, the logo, and the look and feel, are owned by Movement Theory Labs LLC or its licensors and are protected by U.S. and international copyright, trademark, and other intellectual-property laws. Except for the limited license in Section 11, no rights are transferred to you. Feedback you provide is welcome; if you send us feedback, you grant us a perpetual, irrevocable, royalty-free license to use it without obligation.

13. Suspension and termination

13.1 By you

You may stop using the Services and delete your account at any time in Profile → Delete Account. How deletion works and what is removed is described in our Privacy Policy, Sections 11 and 12.

13.2 By us

We may suspend or terminate your access to all or part of the Services at any time, with or without notice, if we believe in good faith that you have violated these Terms, that your account has been compromised, or that suspension is necessary to protect the Services or other users. We will give you reasonable notice except in cases of urgency, illegality, or where notice would compromise the suspension’s purpose.

13.3 Effect of termination

Sections that by their nature should survive termination (including 7.2, 8, 12, 14, 15, 16, 17, 18) will survive. Termination does not entitle you to a refund except as required by law or by Apple’s refund policy.

14. Limitation of liability

To the maximum extent permitted by law:

Nothing in these Terms excludes or limits any liability that cannot be excluded or limited under applicable law — including liability for death or personal injury caused by our negligence, for gross negligence, willful misconduct, or fraud, or for any other liability the law does not permit us to limit. Where the law does not allow a parent or guardian to release or waive a minor’s own claims in advance, nothing in these Terms purports to do so.

Some jurisdictions do not allow the limitation of certain damages, so portions of this section may not apply to you. In that case, our liability will be limited to the greatest extent permitted by law.

15. Indemnification

You agree to defend, indemnify, and hold harmless Movement Theory Labs LLC and its officers, members, employees, agents, and licensors from and against any third-party claim, demand, loss, or expense (including reasonable attorneys’ fees) arising out of or related to (a) your User Content, (b) your use of the Services in violation of these Terms or any law, (c) your violation of any third party’s rights, or (d) your responsibility for any minor for whom you are the parent or guardian. We will tell you about any such claim, allow you to control its defense (with counsel reasonably acceptable to us), and reasonably cooperate at your expense.

16. Governing law and dispute resolution

16.1 Governing law

These Terms are governed by the laws of the State of Florida, United States, without regard to its conflict-of-laws principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

16.2 Venue

Except as provided in Sections 16.3 and 16.4, any action arising out of or related to these Terms will be brought exclusively in the state or federal courts located in Broward County, Florida, and you and we consent to personal jurisdiction there.

16.3 Informal resolution

Before filing any action, you agree to contact us at [email protected] and try to resolve the dispute informally for at least thirty (30) days.

16.4 Arbitration and class-action waiver

PLEASE READ THIS SECTION CAREFULLY — IT AFFECTS YOUR LEGAL RIGHTS, INCLUDING YOUR RIGHT TO SUE IN COURT, TO A JURY TRIAL, AND TO PARTICIPATE IN A CLASS ACTION.

Any dispute that is not resolved informally will be resolved by binding individual arbitration under the AAA Consumer Arbitration Rules in Broward County, Florida, administered by the American Arbitration Association. You and Movement Theory waive any right to a jury trial and to participate in a class action, collective action, or representative action. The parties retain the right to bring an individual action in small-claims court. If 25 or more similar claims are asserted against us by or with the coordination of the same or coordinated counsel, we may require those claims to be administered using batched or bellwether procedures, and the arbitrator will have authority to manage them efficiently and to allocate fees accordingly. You may opt out of this arbitration provision by emailing [email protected] within thirty (30) days of first agreeing to these Terms with the subject line “Arbitration Opt-Out.” This Section does not apply to the extent the law of your jurisdiction makes a pre-dispute consumer-arbitration agreement or class-action waiver unenforceable.

17. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will update the “Effective date” above and post a clear in-App notice the next time you open the App. For material reductions in your rights or material increases in your obligations, we will give at least 14 days’ advance notice and the opportunity to cancel before the change takes effect. Your continued use after the new Terms take effect constitutes acceptance.

18. Miscellaneous

19. Contact

By using the Services, you confirm that you have read, understood, and agreed to these Terms and the Privacy Policy.
