TERMS AND CONDITIONS

Last updated August 8, 2026

When we make material changes to these Terms, we will update the "Last updated" date above and notify you where required.

These Terms and Conditions ("Terms") govern your access to and use of the website and services at https://www.muscleapp.fit (the "Services"), operated by Muscle App(Roberto Carrascoso Jordán), Madrid, Spain ("we," "us"). By creating an account or using the Services, you agree to these Terms. If you do not agree, do not use the Services.

1. THE SERVICE

Muscle App is a fitness platform that connects athletes and trainers. Athletes can track workouts, nutrition, and progress, and subscribe to independent trainers who offer coaching plans through the platform. Trainers can publish a professional profile, offer training plans, and manage their clients.

Muscle App provides the technology platform. Coaching services are provided by the trainers themselves, who are independent professionals (see Section 6).

2. ACCOUNTS AND ELIGIBILITY

To use the Services you must:

Be at least 18 years old (or the age of legal majority in your jurisdiction, if higher)
Provide true, accurate, and complete information when registering
Keep your login credentials secure and not share your account with others
Be responsible for all activity that occurs under your account

You must notify us promptly at support@muscleapp.fit if you suspect unauthorized use of your account.

3. PLANS AND PRICING

The Services are offered under the following plans:

Athlete Free: free of charge, does not expire.
Athlete Premium:€5.99/month or €49.99/year.
Trainer Free: free of charge; an 8% platform fee (commission) applies to the client subscriptions the trainer sells through the platform.
Trainer Premium: €16.99/month or €139.99/year; 0% commission on client subscriptions.

The prices that apply are always the ones displayed at checkout at the time of purchase. We may change prices with prior notice; price changes do not affect periods already paid.

4. PAYMENTS, RENEWAL, AND CANCELLATION

All payments and subscriptions are processed by Stripe, our payment provider. We never store your card numbers.
Paid subscriptions renew automatically at the end of each billing period (monthly or yearly) unless you cancel before renewal.
You can cancel at any time. Cancellation takes effect at the end of the period already paid; you keep access until then. No partial refunds are given for unused time, except where the law requires otherwise.

5. RIGHT OF WITHDRAWAL (EU)

If you are a consumer in the European Union, you have 14 calendar daysfrom the date of purchase to withdraw from your subscription, without giving any reason and without penalty. This is separate from cancelling: cancelling stops the next renewal (Section 4), while withdrawing undoes the purchase you just made.

We do not ask you to waive this right, so it stays available to you for the full 14 days.

Because access to the paid features is activated the moment your payment goes through, you are asking us to begin providing the service straight away. If you then withdraw, we will charge you a proportionate amount for the days you had access, and refund the rest. We will issue that refund without undue delay, and in any case within 14 days of receiving your notice, using the same payment method you paid with.

To withdraw, send us an unequivocal statement — an email to support@muscleapp.fit is enough. You may use the model form below, but you are not obliged to.

If you bought a subscription inside a mobile app store rather than on this website, the store is the seller of record for that purchase, and refunds are handled through Apple or Google under their own terms.

6. TRAINERS

IMPORTANT: If you offer services as a trainer on Muscle App, the Trainer Service Agreement applies IN ADDITION to these Terms. By offering services as a trainer, you agree to BOTH documents. In case of conflict, the more restrictive provision applies.

Trainers are independent contractors, not employees, agents, or partners of Muscle App.
Trainers set their own prices, methods, and availability, and are solely responsible for the services they provide and the content they publish.
Muscle App does not verify trainers' certifications or credentials and does not guarantee the quality or results of any trainer's services.
Trainer profiles are public. See our Privacy Policy for details.

7. NO MEDICAL ADVICE

Muscle App does NOT provide medical advice. The Services, including all workout and nutrition content, are for general fitness purposes only and are not a substitute for professional medical advice, diagnosis, or treatment. Consult a doctor or qualified health professional before starting any training or nutrition program, especially if you have a medical condition. Content published by trainers is the sole responsibility of its authors.

You use the Services and follow any training or nutrition program at your own risk. Stop exercising and seek medical attention if you feel pain, dizziness, or discomfort.

8. CONTENT AND INTELLECTUAL PROPERTY

8.1 Our platform

The platform, its software, design, logos, and branding are the property of Muscle App and are protected by intellectual property laws. These Terms do not grant you any right over them beyond the personal, non-transferable right to use the Services.

8.2 Your content

Content created by users and trainers (workouts, plans, photos, messages, profile information) belongs to its authors. By uploading content, you grant Muscle App a non-exclusive, worldwide, royalty-free license to host, store, display, and process that content solely to operate and provide the Services. This license does not allow us to sell your content or use it for advertising without your consent.

You warrant that your content does not infringe third-party rights or applicable law.

9. ACCEPTABLE USE

You may not:

Use the Services for any unlawful, fraudulent, or harmful purpose
Harass, abuse, or discriminate against other users
Impersonate another person or misrepresent your identity or credentials
Upload content that is illegal, dangerous, or infringes third-party rights
Attempt to breach, probe, or circumvent the security of the platform
Scrape, copy, or resell the Services or their content without authorization
Circumvent the platform's payment system to avoid applicable fees

10. SUSPENSION AND TERMINATION

You may close your account at any time. We may suspend or terminate your account, with notice where reasonably possible, if you materially breach these Terms, engage in fraudulent or unlawful conduct, or put the platform or other users at risk. Where the breach can be remedied, we will give you a reasonable opportunity to remedy it first.

Upon termination, your right to use the Services ends. Provisions that by their nature should survive (intellectual property, limitation of liability, governing law) survive termination. Deletion of your personal data is governed by our Privacy Policy.

11. DISCLAIMERS AND LIMITATION OF LIABILITY

We provide the Services with reasonable care and skill, but we do not guarantee that they will be uninterrupted, error-free, or that they will meet your specific goals (including fitness results).

To the maximum extent permitted by law:

Muscle App is not liable for the services, content, or conduct of trainers, who act as independent professionals.
Muscle App is not liable for indirect damages, loss of profits, or loss of data arising from the use of the Services.
Our total liability to you for claims arising from the Services is limited to the amounts you paid us in the 12 months preceding the event giving rise to the claim.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for willful misconduct or gross negligence, or consumers' statutory rights.

12. CHANGES TO THESE TERMS

We may modify these Terms. When we make material changes, we will notify you with reasonable advance notice through the Services or by email. If you do not agree with the new Terms, you may close your account before they take effect; continued use after that date constitutes acceptance.

13. GOVERNING LAW AND JURISDICTION

These Terms are governed by the laws of Spain. Any dispute arising from these Terms or the Services shall be submitted to the courts of Madrid, Spain, except where you are a consumer and mandatory consumer protection rules give you the right to bring or defend claims before the courts of your place of residence.

14. PRIVACY, COOKIES, AND CONTACT

The processing of your personal data is governed by our Privacy Policy. Our use of cookies is described in the Cookie Policy. Trainers are additionally bound by the Trainer Service Agreement.
