Terms of Service
Last updated: September 17, 2026
These terms are an agreement between you and CloudArbitration LTDA ("we", "us"), the publisher of the Kaha Trainer app ("the app"). By downloading or using the app, you accept them. If you do not accept them, do not use the app.
1. Who can use the app
You must be at least 13 years old, or older where your country requires it. If you are under the age of majority where you live, you may only use the app with the consent of a parent or guardian.
2. What the app is
Kaha Trainer builds strength training programs from rules and a graded exercise catalog, records your workouts and measurements, and shows your progress. It is free to use and supported by advertising. There is no subscription and no purchase.
3. The part that matters most: this is not medical advice
Kaha Trainer is a fitness tool, not a doctor, a physiotherapist or a coach who can see you. The programs, loads, rest periods and calorie figures it produces are general information generated by software from the answers you gave. They are not a diagnosis, a treatment, or personal medical advice.
Resistance training carries a risk of injury. Consult a qualified health professional before starting a training program, especially if you have an existing injury or medical condition, are pregnant, are recovering from surgery, or have not trained in a long time. Stop and seek help if you feel pain, dizziness, chest discomfort or shortness of breath.
You decide what you lift. The "pain or injury" question in the app filters exercises, but it cannot know your body, and no answer you give it makes a load safe. You use the app at your own risk.
Calorie estimates are approximations derived from published formulas. The app does not measure heart rate or any physiological signal. Treat those numbers as a rough guide, not a measurement.
4. Your account
You are responsible for keeping your credentials secure and for everything that happens under your account. Give us accurate information, and tell us at info@kahatrainer.com if you believe your account has been compromised.
You may delete your account at any time by writing to info@kahatrainer.com.
5. Your content
The programs, notes, measurements, gym setups and competitions you create are yours. You grant us only the permission we need to operate the app: to store that content, process it, and display it back to you — and, for a competition, to the other participants of that competition.
You are responsible for what you submit. Do not upload anything unlawful, abusive, or that infringes someone else's rights.
6. Acceptable use
You agree not to:
- reverse engineer, decompile or tamper with the app, except where law permits it;
- access the service through automated means, or attempt to read data belonging to other users;
- interfere with the service, overload it, or probe its security without permission;
- use the app to harass anyone, including through competition names, rules or messages;
- manipulate competition results, or use the app to defraud other participants.
7. Competitions
Competitions are created and run by users, not by us. Whoever creates one defines its exercises, scoring, rules and any prize. We do not organize, sponsor, judge, guarantee or deliver prizes, and we are not a party to any agreement between participants. Results come from what participants log, and we do not verify them. Any dispute about a competition is between its participants.
8. Advertising
The app displays advertising. We do not control the content of individual ads, and an ad appearing in the app is not an endorsement. Your interaction with an advertiser is between you and them.
9. Availability and changes
We may change, suspend or discontinue any part of the app. We may update these terms; if the change is material we will say so in the app before it takes effect, and continuing to use the app after that means you accept the new terms. The app relies on services we do not control, and it may be unavailable at times.
10. Termination
You may stop using the app at any time. We may suspend or terminate your access if you breach these terms or use the app in a way that harms other users or the service. Sections that by their nature should survive termination — disclaimers, limitation of liability, governing law — do survive it.
11. Disclaimer of warranties
The app is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose, merchantability, accuracy and non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that its training recommendations will produce any particular result.
12. Limitation of liability
To the maximum extent permitted by law, we are not liable for indirect, incidental, special or consequential damages, nor for lost data, lost profits, or personal injury arising from your use of the app. Where liability cannot be excluded, it is limited to the greater of the amount you paid us in the last twelve months — which, for a free app, is zero — or the minimum permitted by applicable law.
Nothing in these terms excludes liability that cannot be excluded by law, including for death or personal injury caused by negligence where that exclusion is prohibited. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.
13. Indemnity
You agree to hold us harmless from claims arising out of your misuse of the app, your breach of these terms, or your violation of someone else's rights.
14. Apple
These terms are between you and us, not with Apple. Apple has no obligation to provide support for the app. If the app fails to conform to any applicable warranty, you may notify Apple and Apple may refund the purchase price — which, for a free app, is zero. Apple is a third-party beneficiary of these terms and may enforce them against you.
15. Governing law
These terms are governed by the laws of Brazil, without regard to conflict-of-law rules. Disputes will be heard by the competent courts of Brazil, unless mandatory consumer-protection law in your country of residence gives you the right to bring a claim locally.
