Terms of use

Last updated: 7 October 2026 · Version 2026-10-07 · in force from 7 October 2026

This English translation of Condiciones de uso is provided for convenience. In the event of any discrepancy between the two versions, the Spanish version prevails.

These terms are for you if you use the OnTrain app because your coach has invited you.

Who provides the service

Your coach is the one who trains you and the one you have contracted the training service with: the prices, the sessions and what your plan includes are agreed with them.

Axiren Systems provides the app you both work with. We do not charge you anything, we do not decide your training and we are not a party to the agreement you have with your coach.

The app does not assess your case

This is a tool, not a professional service. It does not diagnose, it does not prescribe, it does not replace anyone and it does not check anything your coach suggests to you. If you have an injury or an illness, are pregnant or take medication, check with your doctor before training. If something hurts, stop.

Nobody from this app reviews your situation. The app does not ask you anything on its own either: what you see in your sign-up form and in your check-ins has been written by your coach, and it is your coach who reads it and decides what to do with your answers. The service is provided to you by your coach, under their judgement and on their responsibility. If something changes or you feel unwell, tell your coach (and your doctor): the app does not find out on its own.

If your coach has switched on the recipe assistant, what it suggests are cooking suggestions, not a plan: it is not advice of any kind and it does not change your plan. Your plan is decided by your coach, and it is your coach you need to ask if you want to change anything.

Your account

You must be of legal age to use the app on your own. If you are a minor, a parent or guardian needs to authorise it and manage the account with you.

Use the app only for your own matters: your training and your communication with your coach. Do not try to access other people's data.

If the recipe assistant is paused

What you write to the recipe assistant goes through the artificial intelligence provider's safety filters. If they block a message, it is discarded and we tell you at that moment. If they repeatedly block your messages, the assistant is paused for you automatically as a precaution, and we tell your coach. The rest of the app keeps working as usual.

The final decision is taken by a person. We review what happened (for that purpose we keep the blocked message for 30 days, pseudonymised: with your name and contact details replaced by codes) and we tell you the reason. Depending on what we find, we switch it back on, give you a warning or, if we had already warned you, switch it off. If you disagree, write to us at privacidad@axirensystems.com.

What you upload

Your progress photos, your measurements, your logs and your messages are yours. We host them so that you and your coach can use them, and for nothing else: we do not sell them, we do not show them to anyone else and we do not use them to train artificial intelligence models.

How we process them is explained in the privacy policy, and you can withdraw your consent whenever you want from your profile.

If something seems wrong

If some content in the app infringes your rights (for example, you appear in a video you did not authorise), let us know at ontrain.app/en/report-content and we will review it.

For anything else related to the app, write to us at privacidad@axirensystems.com. If your problem is with the training, the sessions or the payment, it is your coach who can resolve it.

Leaving

You can stop using the app whenever you want and ask your coach or us to delete your data. Leaving the app does not in itself cancel what you have agreed with your coach: you need to discuss that with them.

If it is your coach who closes your profile, your history is kept for 12 months in case you come back, and once that period has passed it is deleted automatically. If you would rather not wait, ask for it to be deleted: your coach does it within one month at the latest, and if they do not, we do. The periods, in detail, are in the privacy policy.

Changes

If we change these terms, we will let you know within the app before they apply.

Your rights as a consumer

Nothing written here limits the rights that consumer protection law gives you. You can bring a claim before the courts of your place of residence and before the consumer authorities of your autonomous community (comunidad autónoma). Spanish law applies, without this depriving you of the protection of the mandatory rules of your country of residence.
