Terms of Use
Last updated: 2026-06-05
Welcome to Kronos. These Terms of Use are a binding agreement between you and Muller Labs, LLC, a Delaware limited liability company (“Muller Labs,” “we,” “us”), and govern your access to and use of the Kronos mobile application and any related services (together, the “Service”). By checking the consent box, or by tapping a button labeled “agree,” “continue,” or “generate my first workout” in the app, you accept these Terms. If you do not agree, do not use the Service.
1. Eligibility
You must be at least 18 years old to use the Service. The Service is not directed to anyone under 18, and we do not knowingly collect information from anyone under 18.
2. License
Subject to your compliance with these Terms, we grant you a personal, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Service on devices you own or control, for your personal, non-commercial use only.
3. The Service
Kronos generates personalised workout suggestions using artificial intelligence based on the inputs you provide (such as available equipment, fitness level, goals, and any free-text notes about injuries or limitations).
The Service is a software tool. It is not a fitness coach, personal trainer, physiotherapist, doctor, or other licensed professional. Suggestions provided by the Service have not been reviewed by a qualified human professional before they are shown to you.
4. AI-Generated Content
Workouts, exercise selections, durations, repetitions, rest intervals, and other content produced by the Service are generated algorithmically and may contain errors, omissions, or recommendations that are inappropriate for your particular circumstances.
You are solely responsible for evaluating each suggestion before acting on it, and for substituting or skipping any element that you judge to be unsafe, uncomfortable, or unsuitable.
5. Assumption of Risk
Physical exercise carries inherent risks, including (without limitation) muscle strains, sprains, fractures, cardiovascular events, heat illness, and other injuries up to and including death.
By using the Service, you knowingly and voluntarily assume all such risks to the maximum extent permitted by the law of your jurisdiction. You acknowledge that we cannot evaluate your physical condition, training experience, or medical history, and that any decision to perform any suggested activity is yours alone.
6. Your Account
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You agree to provide accurate information at sign-up and to keep it updated.
7. Subscriptions and Billing
Some features of the Service require a paid subscription. Subscriptions are sold and billed through the Apple App Store or Google Play Store and are governed by their respective payment, refund, and auto-renewal policies. You can manage or cancel a subscription at any time through your Apple or Google account settings.
8. App Store Terms
These Terms are between you and Muller Labs, LLC only, not with Apple Inc. (“Apple”) or Google LLC (“Google”), and neither Apple nor Google is responsible for the Service or its content. Apple and Google have no obligation to provide any maintenance or support for the Service.
If the Service fails to conform to an applicable warranty, you may notify the store you obtained it from (Apple or Google), which may refund any purchase price you paid for it; to the maximum extent permitted by law, Apple and Google have no other warranty obligation for the Service. Apple and Google are not responsible for addressing any claims relating to the Service, including product liability claims, claims that the Service fails to conform to a legal or regulatory requirement, claims under consumer protection law, or third-party claims that the Service infringes intellectual property rights.
You represent that you are not located in a country subject to a U.S. government embargo and that you are not on any U.S. government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
9. Acceptable Use
You agree not to (a) reverse engineer, decompile, or attempt to extract the source code of the Service; (b) use the Service to violate any law or third-party right; (c) scrape, mass-download, or otherwise extract data from the Service by automated means; (d) interfere with the Service’s normal operation; or (e) misrepresent your identity or affiliation.
10. Intellectual Property
The Service, including its software, design, text, graphics, and trademarks, is owned by us and our licensors and is protected by intellectual property laws. Workout content you generate through the Service is provided for your personal use; you may not republish or commercially exploit it without our prior written consent.
11. Termination
You may stop using the Service and delete your account at any time. We may suspend or terminate your access to the Service at our discretion, including for breach of these Terms or to comply with law. Sections that by their nature should survive termination (including liability limitations, indemnification, and dispute resolution) will continue to apply.
12. Disclaimers
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SAFE, OR APPROPRIATE FOR YOUR HEALTH OR FITNESS NEEDS.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.
13. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING FROM OR RELATED TO THE SERVICE.
OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE TOTAL AMOUNTS YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS (USD $100).
NOTHING IN THESE TERMS EXCLUDES OR LIMITS ANY LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, INCLUDING ANY NON-WAIVABLE LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR FOR FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT. THE LIMITATIONS IN THIS SECTION APPLY ONLY TO THE EXTENT PERMITTED BY THE LAW OF YOUR JURISDICTION.
14. Indemnification
You agree to defend, indemnify, and hold harmless Muller Labs, LLC, its affiliates, and their respective officers, directors, employees, and agents from any third-party claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to your use of the Service, your violation of these Terms, or your violation of any law or third-party right.
15. Governing Law
These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws principles. If the consumer-protection law of the place where you live gives you rights or remedies that cannot be waived by contract, nothing in these Terms takes them away from you.
16. Dispute Resolution and Arbitration
Please read this section carefully. It affects your rights.
Informal resolution first: before filing any claim, you agree to contact us at legal@kronosstudio.app with a written description of the dispute and give us 30 days to try to resolve it with you informally.
Small claims: either party may bring an individual claim in small-claims court instead of arbitration, if the claim qualifies.
Arbitration agreement: except as provided in this section, any dispute arising out of or relating to these Terms or the Service will be resolved by final and binding arbitration administered by JAMS under its applicable rules and its Consumer Arbitration Minimum Standards, rather than in court. The arbitration will be conducted by a single arbitrator, by videoconference or, at your election, in or near the county where you live.
Class waiver: YOU AND WE EACH WAIVE ANY RIGHT TO A TRIAL BY JURY AND AGREE THAT DISPUTES WILL BE RESOLVED ONLY ON AN INDIVIDUAL BASIS, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS, COLLECTIVE, OR REPRESENTATIVE PROCEEDING.
Carve-outs: this section does not prevent either party from seeking injunctive or other equitable relief in a court of competent jurisdiction to protect intellectual property, and it does not waive any right to seek public injunctive relief in court where the law prohibits waiving that right.
Your right to opt out: you may opt out of this arbitration agreement entirely, with no effect on the rest of these Terms, by emailing legal@kronosstudio.app within 30 days of first accepting these Terms. Include your name, the email address on your account, and a statement that you opt out of arbitration.
Coordinated filings: if 25 or more arbitration demands raising similar claims are filed against us by the same or coordinated counsel, you and we agree the demands will be resolved in staged batches of no more than 25, with arbitration fees for each batch due only as that batch proceeds.
Severability: if the class waiver is found unenforceable as to a particular claim, that claim (and only that claim) will proceed in court rather than arbitration. If any other part of this section is found unenforceable, the remainder stays in effect.
17. Changes to These Terms
We may update these Terms from time to time. When we make a material change, we will revise the version date above and re-prompt you for consent the next time you open the app. Your continued use of the Service after acceptance of an updated version constitutes acceptance of the new Terms.
