Terms and Conditions

Last updated: October 2026

This document was written in Spanish and this translation is provided for convenience only: in the event of any discrepancy or question of interpretation, the Spanish version prevails.

1. Acceptance of the Terms

By creating an account or using ATHRIX ("the Platform"), you accept these Terms and Conditions and our Privacy Policy. If you do not agree, do not use the Platform. These terms constitute a legal agreement between you and ATHRIX.

2. Description of the Service

ATHRIX is a training management technology platform that connects athletes with gyms, trainers and sports professionals. It lets you organize routines, log progress, sign up for sporting events and access an artificial intelligence assistant that provides general guidance.

ATHRIX is operated by DUAL LABS SAS. It is a technology intermediary: we do not provide medical, nutritional or personal training services on our own account.

On Apple devices, ATHRIX offers an optional integration with Apple Health (HealthKit) to import your workout metrics (duration, calories and heart rate) when you complete them in the app. You can turn it on or revoke it whenever you want; how that data is processed is detailed in the Privacy Policy.

3. Types of User

The Platform recognizes two types of user:

  • Athletes: natural persons who use the mobile app to train, log progress and, eventually, link up with an organization (gym, coach, professional).
  • Organizations: gyms, trainers and sports professionals who use the web app to manage athletes, create routines, organize events and communicate with their community. Organizations may be legally constituted legal entities or natural persons who carry out their professional activity independently; in both cases they operate through an institutional account from which they manage their staff (coaches, administrators, assistants).

When an Athlete joins an Organization, certain training, assessment and progress data become visible to that Organization, in accordance with the Privacy Policy. The Organization assumes the role of data controller for the data it generates about the Athlete itself (assigned routines, assessments, notes, communications), and ATHRIX acts as data processor for that information.

4. Eligibility and Minimum Age

You must be at least 18 years old to create an Athlete account on ATHRIX. By signing up, you declare under oath that you are of legal age. If we detect accounts belonging to people under 18, we will suspend them and delete the associated data.

To create an Organization account, in addition to being of legal age, you must have the legal capacity to enter into contracts on behalf of the entity and, if the activity requires it (personal training, nutrition, physiotherapy or other regulated professions), hold the current professional credentials or qualifications required by applicable law. The person who creates the account declares that they are authorized by the Organization to link it to ATHRIX and to accept these terms on its behalf.

You are responsible for keeping your password confidential and for all activity that occurs from your account. Organizations are additionally responsible for managing the addition and removal of their staff and for safeguarding the associated credentials. Notify us immediately of any unauthorized use.

5. Medical and Health Disclaimer

⚠️ ATHRIX is not a medical service. The content on the Platform — routines, recommendations, AI assistant responses, coach notes — is for informational and guidance purposes. It does not replace the advice of a physician, nutritionist or other health professional.

Before starting any training or nutrition program, consult a qualified health professional, especially if you have injuries or medical conditions, are pregnant or take medication.

You use the Platform at your own risk. ATHRIX is not liable for injuries, health problems, financial losses or any other damage arising from the use of the routines, coach recommendations or AI assistant responses.

The metrics you import from Apple Health or other devices (for example, calories or heart rate from your Apple Watch) are for reference only and come from your device: ATHRIX does not guarantee their accuracy and they must not be used for diagnostic purposes.

6. Artificial Intelligence Assistant

The Platform includes a conversational assistant powered by language models. Your conversations are processed through Vercel's AI Gateway (based in the United States), which routes them to the provider that runs each model: Microsoft Azure or Google Cloud (Vertex AI), also in the United States. The models are made by OpenAI and Google, but the ones who run them — and therefore the ones who receive your messages — are those two companies. To personalize the responses, we send them the necessary context: profile, goals, training history and the messages you send to the assistant.

All of them act as data processors: they process that data solely to answer your query and following our instructions. Every request requires the provider that receives it to not use your data to train its models and to not retain it once the query has been answered; if no available provider meets both conditions, the request fails instead of being sent anyway. The details are in section 4 of our Privacy Policy.

⚠️ The AI assistant's responses may be inaccurate, incomplete or out of date. They do not constitute medical, nutritional, pharmacological or professional advice of any kind. ATHRIX is not liable for decisions made on the basis of the assistant's responses.

7. Sporting Events and Activities

The Platform lets Organizations publish their sporting events to promote them. Registration, organization, execution, safety and any liability for the event rest exclusively with the Organization that publishes it, and are handled outside the Platform. ATHRIX does not take registrations or process payments for events.

8. Payments between Coaches and Athletes

Downloading and basic use of the mobile app are free for Athletes. Any fee, dues or payment between an Athlete and their coach, gym or Organization is exclusively between the parties: ATHRIX does not receive that money, does not set the prices and is not liable for financial disputes arising from that relationship.

When the Organization connects its own Mercado Pago account, the Platform lets the Athlete authorize the recurring payment from a payment link. To do so, the Athlete enters the email of their Mercado Pago account — which may not be the one they use on ATHRIX — and ATHRIX sends it to Mercado Pago to create the authorization in the Organization's name, and keeps a copy alongside the subscription so it doesn't have to ask for it again and to reflect the status of the charge. ATHRIX does not see or store card details: that happens entirely within Mercado Pago.

The Mercado Pago account belongs to the Organization and the money goes directly to it. From that account, the Organization has access to the Athlete's email and the payment details, and is responsible for the use it makes of them and for the billing relationship (receipts, claims, refunds and cancellations). Mercado Pago's processing of that data is governed by Mercado Pago's policies.

For each charge that an integrated payment provider processes through the Platform, ATHRIX charges the Organization a fee of 1% of the transaction amount, with a minimum of US$0.10 per transaction, billed in ATHRIX credits. It is a charge separate from the money the Athlete pays, which goes in full to the Organization's account.

The fee accrues for each charge processed, regardless of the status of the Organization's credits subscription. If that subscription is not active, the recurring payment authorizations that Athletes have already granted continue to charge and fees continue to accrue; those accrued during that period are billed when the Organization reactivates the subscription.

9. Acceptable Use

You may not use the Platform to:

  • Carry out illegal or fraudulent activities or activities that violate third-party rights.
  • Harass, intimidate, impersonate or threaten other users.
  • Upload defamatory, discriminatory, violent or sexual content.
  • Attempt to access other users' data without authorization, or tamper with the Platform's security.
  • Reverse engineer, perform mass scraping, or use the Platform to train artificial intelligence models.

Messages and content sent by users: Messages lets athletes and Organizations exchange text, photos, videos, audio and PDF files. Each user is solely responsible for the content they send and declares that they hold the rights needed to share it. Messages are private between the athlete and their Organization: ATHRIX does not review or moderate them, and is not responsible for their accuracy, their legality or any damage they may cause.

ATHRIX may remove content and suspend accounts upon a credible report, an order from a competent authority or a breach of these Terms, in accordance with section 12. To report content, write to us at soporte@athrix.fit.

10. Obligations of Organizations

Organizations that use ATHRIX to provide services to their athletes undertake, in addition to the general obligations of these Terms, to:

  • Accuracy and validity: provide accurate information about the Organization and its staff, and keep up to date the professional credentials or qualifications their activity requires.
  • Own content: be responsible for the content they upload to the Platform (routines, exercises, assessments, notes, events, communications) and ensure that it does not infringe third-party rights or applicable law.
  • Professional relationship with their athletes: take responsibility for providing the professional service (training, advice, event organization). ATHRIX is a technology intermediary and does not take part in that relationship.
  • Data protection: comply with Law 18.331 with respect to the athlete data they manage, acting as data controller for the information they generate about them, as detailed in the Privacy Policy.
  • Safeguarding credentials: protect their staff's access, promptly remove people who leave the Organization and notify ATHRIX of any security incident they detect.
  • Proper use: use the Platform solely for the purposes of the service they provide to their athletes, without disclosing data to third parties or using it for unrelated purposes.
  • Charging with Mercado Pago: if they connect their account to charge their athletes from the Platform, answer for that billing relationship and for the use they make, from their own account, of the email and payment details of those who pay them, complying with Mercado Pago's terms and applicable regulations, in accordance with section 8.
  • Events: bear ultimate responsibility for the events they organize and publish, for running them and for looking after those who take part, in accordance with section 7.

Failure to meet these obligations may result in the suspension or closure of the Organization's account, in accordance with section 12.

11. Intellectual Property

The Platform, its design, code, brand, logos and own content are the exclusive property of DUAL LABS SAS and are protected by Uruguayan and international intellectual property law.

The routines, exercises and content created by Organizations are the property of each Organization. By uploading content to the Platform (routines, photos, videos, audio, documents, notes, posts, messages), you grant us a non-exclusive, worldwide, royalty-free license to store, display and process that content for the sole purpose of providing you with the service.

Fonts and other third-party resources: the Platform lets Organizations upload files created by third parties to customize their public page (for example, a font in .otf format). By uploading one of these files, the Organization declares that it holds the rights or licenses needed to use it and display it on its website. The rights over those files and the responsibility for their use belong exclusively to the Organization that uploads them: ATHRIX merely hosts and displays them in order to provide the service, acquires no rights over them and may remove them upon a credible claim from a third party or a breach of this clause.

If you believe any content violates your intellectual property rights, write to us at soporte@athrix.fit with a description of the content and proof of your rights.

12. Account Suspension and Closure

You can close your account at any time from your account settings. The effects of closing your account on your data are governed by our Privacy Policy.

ATHRIX may suspend or close your account if: you breach these terms, make fraudulent, abusive or illegal use of the Platform, put other users or the infrastructure at risk, or if a competent authority orders us to do so. In serious cases the suspension is immediate; in minor cases, we will notify you beforehand.

13. Limitation of Liability

The Platform is provided "as is" and "as available". We do not guarantee uninterrupted availability, the absence of errors or specific training results.

To the fullest extent permitted by Uruguayan law, DUAL LABS SAS will not be liable for indirect damages, loss of profits, loss of data, or interruptions caused by third parties (including, among others, infrastructure providers, OpenAI, Google, Cloudflare) or force majeure events.

14. Changes to the Terms

We may modify these terms to reflect changes in the service, legal requirements or improvements. We will notify you of significant changes at least 15 days in advance by email or through a visible notice within the Platform. Continued use after that notice implies your acceptance of the new terms.

15. Governing Law and Jurisdiction

These terms are governed by the laws of the Oriental Republic of Uruguay. Any dispute arising from the use of the Platform will be submitted to the competent Courts of the city of Montevideo, waiving any other venue or jurisdiction that may apply.

If you are a consumer within the meaning of Law 17.250 on Consumer Relations, you retain the rights and choice of venue that law grants you.
