Kentro

Terms of Service

Effective October 15, 2026 · Version 2026-10-15

These Terms are a binding agreement between you and Kentro ("Kentro", "we", "us") for the Kentro website, web app and mobile apps (the "Service"). Section 15 requires most disputes to be resolved by individual arbitration and waives class actions and jury trials. Please read it.

You accept these Terms, the Privacy Policy, the Consumer Health Data and Biometric Notice and the Waiver, Assumption of Risk and Release of Liability (together, the "Agreement") by ticking the boxes when you create an account or when we ask you to accept an updated version. Trainers also accept the Trainer Terms. If you do not agree, do not use the Service.

1. Who can use Kentro

  • You must be at least 18 years old to create an account.
  • A trainer may scan someone under 18 only with a parent or legal guardian's permission, and is responsible for getting it. Kentro is never directed to children under 13, and we do not knowingly collect their information.
  • You must give accurate information and keep it current.

2. What Kentro is, and is not

  • Kentro is a general wellness and fitness tool. It estimates posture and movement from a phone camera, explains common patterns in plain language, and suggests general corrective exercises.
  • Kentro is not a medical device and does not provide medical advice. It does not diagnose, treat, cure, mitigate or prevent any disease, injury or condition. Results are estimates that can be wrong or incomplete and are not a clinical assessment.
  • Using Kentro does not create a doctor-patient, therapist-patient or any other professional relationship with Kentro.
  • Always seek the advice of a physician or other qualified professional about a medical condition or before starting an exercise program. Never ignore professional advice or delay seeking it because of something in Kentro.
  • If you have a medical emergency, call 911 or your local emergency number. Messages in Kentro are not monitored for emergencies.

3. Your health and safety

  • You are responsible for deciding whether an activity is right for you. Answer the safety check before each scan honestly and follow its advice.
  • Exercise only within your limits, in a clear space, on a stable surface, with a chair or wall within reach for balance movements.
  • Stop immediately if you feel pain, dizziness, shortness of breath, chest pain, or anything unusual, and seek medical help if needed.
  • The Waiver is part of these Terms. In it you assume the risks of physical activity and release Kentro from claims, to the fullest extent the law allows.

4. Trainers and other professionals

Trainers, coaches and therapists who use Kentro are independent. Kentro does not employ, supervise, vet, certify, license or endorse them and is not responsible for their advice, programming, supervision or conduct. Your relationship with a trainer is between you and them.

5. AI features

Some features use artificial intelligence, for example drafting replies a trainer may send you, or drafting marketing copy. AI output can be inaccurate or incomplete. It is not professional advice, and anything written with it is reviewed and sent by a person who is responsible for it.

6. Your content and data

  • You keep ownership of the information you add. You give Kentro a worldwide, non-exclusive, royalty-free license to host, process, display and transmit it only to run, secure and improve the Service and as the Privacy Policy describes.
  • We may create and use de-identified or aggregated information that does not identify you to understand and improve the Service.
  • If you turn on a report link, anyone with the link can view that report until you turn it off.
  • If you send feedback or ideas, we may use them without obligation to you.

7. Acceptable use

Do not: break the law; add, scan or message anyone without their permission; upload content you have no right to share; harass anyone; access data that is not yours; probe, scrape, reverse engineer, overload or disrupt the Service; get around security or usage limits; use the Service to build a competing product; or present Kentro results as a medical diagnosis.

8. Accounts

Keep your password private. You are responsible for activity on your account. Tell us at hello@getkentro.com if you think your account was misused. You can delete your account at any time from the Account page.

9. Fees

Kentro is currently free. If we introduce paid plans, we will show the price and terms before you buy, and nothing will be charged without your agreement.

10. Changes to the Service and these Terms

We may change, suspend or stop any part of the Service. We may update the Agreement; when the changes are material, we will ask you to accept them in the app before you continue. Continuing to use the Service after accepting means you agree to the updated version.

11. Third parties

The Service relies on third parties (for example app stores, hosting, notification services and AI providers). Their services are governed by their own terms, and Kentro is not responsible for them.

12. Disclaimer of warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE FULLEST EXTENT PERMITTED BY LAW, KENTRO DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTY THAT RESULTS WILL BE ACCURATE, THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE, OR THAT ANY EXERCISE IS SAFE OR SUITABLE FOR YOU.

13. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW: (A) KENTRO AND ITS OWNERS, OFFICERS, EMPLOYEES, CONTRACTORS AND PARTNERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, DATA OR GOODWILL, ARISING OUT OF OR RELATED TO THE SERVICE, EVEN IF ADVISED OF THEIR POSSIBILITY; AND (B) THEIR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SERVICE OR THIS AGREEMENT IS LIMITED TO THE GREATER OF ONE HUNDRED U.S. DOLLARS (US$100) OR THE AMOUNT YOU PAID KENTRO IN THE 12 MONTHS BEFORE THE CLAIM. These limits apply to every theory of liability, including contract, tort (including negligence), strict liability and statute, and are an essential part of the bargain. Some places do not allow certain limits, so some may not apply to you.

14. Indemnity

You will defend, indemnify and hold harmless Kentro and its owners, officers, employees, contractors and partners from any claim, loss, liability or expense (including reasonable attorneys' fees) arising out of your use of the Service, your content, your breach of the Agreement, your violation of law or of someone else's rights, or, for trainers, the services you provide to your clients.

15. Disputes: informal resolution, arbitration and class action waiver

Talk to us first

Before filing a claim, you agree to email hello@getkentro.com with a description of the dispute and try to resolve it informally for 30 days.

Binding individual arbitration

Any dispute arising out of or relating to the Service or this Agreement will be resolved by final and binding arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, before a single arbitrator, and not in court. Either party may instead bring an individual claim in small claims court if it qualifies. The Federal Arbitration Act governs this section. The arbitrator decides all issues, except that a court decides questions about the class action waiver and about whether a claim must go to small claims court.

No class actions, no jury

You and Kentro may bring claims only in an individual capacity, not as a plaintiff or class member in any class, collective, consolidated or representative proceeding, and each waives the right to a jury trial. If this waiver is found unenforceable for a claim, that claim must be decided by a court, not in arbitration.

Opting out

You can opt out of arbitration within 30 days of first accepting these Terms by emailing hello@getkentro.com with your name, account email and a statement that you opt out of arbitration.

Governing law and venue

The laws of the State of California govern this Agreement, without regard to conflict of laws rules. Any claim not subject to arbitration will be brought exclusively in the state or federal courts located in California, and both parties consent to their jurisdiction. Any claim must be brought within one year after it arises, to the extent the law allows.

16. Ending your use

You can stop using the Service and delete your account at any time. We may suspend or end access if you break the Agreement or to protect people or the Service. Sections that by their nature should survive (including the Waiver, disclaimers, limits of liability, indemnity and dispute terms) survive.

17. General

This Agreement is the entire agreement between you and Kentro about the Service. If any part is unenforceable, the rest remains in effect. Our not enforcing a term is not a waiver. You may not transfer this Agreement; we may transfer it in a merger, acquisition or sale of assets. We are not liable for delays or failures caused by events beyond reasonable control. Notices to us: By email to hello@getkentro.com.
