Terms of Use — EvoluaFit

1. Acceptance

By installing, accessing or using EvoluaFit, you declare that you have read and accepted these Terms of Use and the Privacy Policy. If you disagree with any point, do not use the service. If you use the app on behalf of a company or a coaching business, you declare that you have authority to bind it to these terms.

2. What EvoluaFit is — and is not

EvoluaFit is a tool for logging, organising and visualising body assessment data, with educational support features including artificial intelligence analyses, physiological calculators, treatment tracking and reports.

EvoluaFit is not a medical device. It does not diagnose, treat, prevent or cure any condition. No number, chart, text, image projection or AI answer in the app constitutes a diagnosis, prescription, meal plan, training plan or medical advice. Body fat percentages, masses and projections are estimates derived from population formulas, with a margin of error, useful for tracking a trend over time — not for clinical decisions.

Decisions about health, medication, diet and exercise must be made with a qualified professional. If you have a symptom, pain, discomfort or a clinical question, seek medical care. Do not stop or adjust treatment because of something you read in the app.

3. Your account

To use EvoluaFit you need an account. When creating one, you commit to:

Providing truthful information and keeping it up to date.
Being at least 13 years old and, if under 18, having the consent and supervision of a legal guardian.
Keeping your credentials confidential and not sharing the account.
Being responsible for all activity carried out in your account.
Telling us immediately if you suspect unauthorised access.

An account is personal. Professionals following several clients must use Personal Trainer mode, not shared accounts.

4. Premium subscription

Some features require the Premium subscription, offered in monthly and yearly plans.

Free trial: when available, the trial period is 3 days. If you do not cancel before it ends, the subscription is charged automatically.
Billing and renewal: the purchase is processed and charged by the Apple App Store or Google Play, depending on the origin store, and renews automatically until cancelled. We neither receive nor store your payment details.
Cancellation: done in the store's subscription settings, at any time, taking effect at the end of the period already paid. Cancelling does not erase your data — your history stays available on the free plan.
Refunds: follow the policy of the store where the purchase was made. Consumers in Brazil keep the 7-day right of withdrawal under article 49 of the Consumer Protection Code.
Prices: may change. Changes are announced in advance and apply only to future cycles, never retroactively.

5. Your content

Photos, videos, measurements, notes and everything else you log remain yours. We claim no ownership over any of it.

You grant us only the limited, non-exclusive, revocable licence needed to operate the service for you: store, transmit, display, process, generate reports and — when you trigger the AI — send the necessary slice to inference providers. That licence ends when you delete the content or the account. We do not use your content in advertising, we do not publish it and we do not train models on it.

You are responsible for what you upload and declare that you hold the rights to the images you record. When running assessments for third parties in Personal Trainer mode, you declare that you obtained the consent of the person assessed.

6. Artificial intelligence features

AI features are optional, subject to usage limits per period, and depend on a connection and on third-party providers. You understand that:

AI output may contain errors, inaccuracies or outdated statements, and must be treated as a suggestion, never as clinical truth.
Visual projections, including Future Vision, are computer-generated illustrations and not a prediction of results. No body result is promised or guaranteed.
We may change, limit or discontinue AI features, including because of supplier unavailability.
Using the AI to obtain guidance meant to replace health treatment, or to generate illegal content or third-party content without consent, is prohibited.

7. Personal Trainer mode

The link between professional and client always depends on the client's explicit acceptance and can be undone by either party, at any time, with access cut immediately.

By using professional mode, you declare that you hold the qualification required for your activity in your jurisdiction, you take full technical responsibility for the guidance you give your clients, and you commit to handling their data under the applicable data protection law. NAMIX LTDA - ME provides the tool; the professional relationship, the prescription and the billing between you and your client are yours alone.

8. Referral programme

The referral programme lets you share a personal code with new users. Self-referral, creating fake accounts, using automated mechanisms or spreading the code as spam are prohibited. Benefits obtained irregularly are cancelled, and abuse may lead to account termination. The programme's rules and rewards may be changed or ended at any time.

9. Prohibited use

You may not:

Use the service for illegal purposes or to violate third-party rights.
Try to access other users' data, bypass security rules or exploit vulnerabilities.
Reverse engineer, decompile or extract the app's code, except as permitted by law.
Scrape data, automate bulk access or deliberately overload the infrastructure.
Upload unlawful or offensive content, or images of another person without their consent.
Resell, sublicense or redistribute the service without written authorisation.
Use the app as an official clinical record or as the sole basis for a medical decision.

10. Intellectual property

The EvoluaFit brand, logo, software, interface, texts, icons and service architecture belong to NAMIX LTDA - ME or its licensors and are protected by intellectual property law. These terms grant you only a personal, limited, revocable and non-transferable licence to use the app for non-commercial purposes — except for the professional use expressly provided for in Personal Trainer mode.

11. Warranties and limitation of liability

The service is provided as is. We do not guarantee uninterrupted operation, absence of errors, permanent availability of features that depend on third parties, or absolute accuracy of estimates.

To the maximum extent permitted by applicable law, NAMIX LTDA - ME is not liable for indirect damages, lost profits, data loss caused by a failure of your device, or health decisions made based on information from the app. Our total liability, where it exists, is limited to the amount you paid for the service in the 12 months before the event.

Nothing in these terms removes non-waivable consumer rights, or liability for wilful misconduct or gross negligence.

12. Suspension and termination

You may end the relationship whenever you want, by deleting the account in the app or on the Delete my account page. We may suspend or terminate access, with notice where possible, in case of breach of these terms, fraud, risk to other users' security or legal requirement. Once the account is closed, clauses that by nature survive — intellectual property, limitation of liability and jurisdiction — remain in force.

13. Changes to the service and the terms

EvoluaFit evolves: features may be added, changed or discontinued. We may revise these terms and, when a change is material, we will tell you in the app or by email before it takes effect. If you disagree with the new version, close your account — continuing to use it means accepting.

14. Governing law and jurisdiction

These terms are governed by the laws of the Federative Republic of Brazil. The consumer's place of domicile is the chosen forum for consumer claims; for all others, the forum of NAMIX LTDA - ME's head office applies. Before any legal action, we encourage direct contact at suport@evoluafit.site — almost everything gets solved in a conversation.
