This document is published in several languages. If the versions differ in any way, the Spanish version prevails.

1. Scope and acceptance

These terms govern the use of the Aszen mobile app (the "app"), a tool for tracking diet, training and body progress.

By downloading, installing or using the app you accept these terms. If you do not agree with them, do not use the app.

The processing of your personal data is governed by the Privacy policy, which forms part of these terms.

2. Owner

3. Licence to use

We grant you a personal, limited, revocable, non-exclusive and non-transferable licence to use the app on devices you own or control, for personal, non-commercial purposes.

No intellectual property rights are transferred to you. In particular, you may not:

4. Your account

The app can be used without an account, in local mode. If you create an account to sync your data:

An account is personal and non-transferable.

5. Important medical notice

Aszen is not a medical device and does not provide medical services. The calorie, macronutrient, set, rep and intensity targets the app computes or suggests are general estimates based on public formulas and on the data you enter.

The information in the app is not a substitute for the advice, diagnosis or treatment of a healthcare professional. Consult your doctor before starting a training programme or changing your diet, especially if you are pregnant or breastfeeding, have a medical condition, take medication or have suffered an injury.

If you experience any symptom during exercise, stop and seek medical attention. You use the app at your own risk.

Nutritional data comes from public databases and third-party contributions; it may contain errors and its accuracy is not guaranteed. If you have an allergy or an intolerance, always check the product's actual label.

6. Premium subscription

Some features are paid. The subscription is purchased and billed through the app store you installed Aszen from (Apple's App Store or Google Play), not directly by us.

Access to paid features may take a few minutes to appear after purchase. If you have paid and it does not activate, write to us.

A way in without paying. Artificial intelligence requests can also be unlocked by watching a rewarded ad, without subscribing to anything. It is optional and you always start it yourself. The number of rewards available per day is limited, and we may change that limit, change what each ad grants, or withdraw the option at any time: it is not an acquired right and it does not replace the subscription. How the ad works and what data it involves is explained in the privacy policy.

7. Your content and imported data

Everything you record — workouts, meals, measurements, your own foods, menus and cover images — remains yours. We claim no ownership over it.

You grant us only the technical licence strictly necessary to host, transmit and display it to you within the app, and to sync it across your devices. That licence ends when you delete the content or your account.

If you import data from another app via a CSV file, you represent that you are entitled to do so. The import does not overwrite days that already hold data unless you explicitly allow it, and it can be undone from the app.

You are responsible for keeping your own copies. Although we sync your data, the app is not a backup service.

8. Acceptable use

When using the app you agree not to:

9. Third-party content and attribution

The app incorporates third-party data and materials, used under their licences and with the attribution they require:

These materials belong to their respective owners and are provided "as is". We are not responsible for their accuracy or availability.

10. Availability and changes to the service

We work to keep the app available and working correctly, but we do not guarantee uninterrupted or error-free operation. Syncing requires an internet connection and depends on third-party services.

We may add, change or withdraw features, and we may require a minimum app version to keep syncing data where a technical change makes it necessary. Paid features that are withdrawn will be compensated proportionally if you are subscribed.

11. Disclaimer of warranties

The app is provided "as is" and "as available", without warranties of any kind beyond those mandatory law imposes. In particular, we do not warrant that the calculations, estimates or suggestions will produce any specific health, weight or performance outcome.

If you are a consumer, this clause does not limit the statutory guarantees you are entitled to.

12. Limitation of liability

To the fullest extent permitted by law, we are not liable for indirect damages, loss of profit, loss of data, or damages arising from the use of or inability to use the app.

Our total liability to you, on any basis, is limited to the amount you paid for the app in the 12 months preceding the event giving rise to the claim.

Nothing above excludes or limits our liability for wilful misconduct, gross negligence, death or personal injury caused by negligence, or any other liability that cannot lawfully be excluded.

13. Suspension and termination

You may stop using the app at any time, erase your local data from Settings, or request deletion of your account by writing to us.

We may suspend or terminate your access if you materially breach these terms, with prior notice unless a legal or security risk prevents it. Termination does not affect your right to request your data under the Privacy policy.

14. Changes to these terms

We may amend these terms. We will update the date in the header and, where the change is material, tell you inside the app. If you keep using the app after the change takes effect, you will be deemed to accept it; if you do not accept it, you may stop using the app and cancel your subscription in the store.

15. Governing law and jurisdiction

These terms are governed by the laws of Spain.

If you are a consumer, you may bring and defend claims before the courts of your place of residence, and you keep the protection of the mandatory rules of your country. Otherwise, the parties submit to the courts of the owner's domicile.
