Terms and Conditions of Use

Last updated: 29 July 2026

Version 1.0 · Last updated: 29 July 2026 Effective date: 6 August 2026


1. Who we are

This application is owned by:

  • Owner: Joan Cama Ribot, sole trader, operating under the trade name Somia Digital
  • Tax ID (NIF): 41531670H
  • Registered address: C/ Sant Joan, 16, 17200 Palafrugell (Girona), Spain
  • Contact email: hola@somia.digital

Hereinafter, "Somia Digital", "we" or "the owner".

This information is provided in compliance with article 10 of Spanish Act 34/2002 of 11 July on information society services and electronic commerce (LSSI-CE).


2. What these terms are and what they apply to

These terms and conditions (the "Terms") govern access to and use of the Strato mobile application for iOS (the "App" or "Strato"), its free features and the paid Strato Pro subscription.

The Terms are a contract between you and Somia Digital. Downloading, installing or using Strato means you accept them in full. If you do not accept them, do not use the App and uninstall it.

The processing of your personal data is not governed here, but by the Privacy Policy, available at https://stratofitness.com/privacidad, which forms an inseparable part of these Terms.

Use of the stratofitness.com website is governed by its Legal Notice and its Cookie Policy, published on that same site.


3. Who may use Strato

To use Strato you must be at least 16 years old and have the legal capacity to enter into a binding contract. If you are under the age of majority but 16 or older, you need the consent of your parent or guardian in order to purchase Strato Pro.

Strato is not directed at children under 16 and we do not knowingly collect their data. If we detect that a user does not meet the minimum age, we may suspend their access.


4. Licence of use

Somia Digital grants you a personal, limited, non-exclusive, non-transferable and revocable licence to install and use Strato on the Apple devices you own or control, in accordance with the App Store Usage Rules and with these Terms.

We are not selling you the App: we are licensing its use to you. All rights not expressly granted are reserved.

4.1 Relationship with Apple's terms

Strato is distributed exclusively through the Apple App Store. Accordingly:

a) These Terms supplement, and do not replace, Apple's standard Licensed Application End User License Agreement and the Apple Media Services Terms and Conditions, which apply to you as an App Store user. b) These Terms are concluded between you and Somia Digital, not between you and Apple. Somia Digital, and not Apple, is solely responsible for the App and its content. c) Maintenance and support. Providing support for the App is solely our responsibility. Apple has no obligation whatsoever to furnish any maintenance or support services with respect to the App. d) Warranty. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App. Any other warranty claim is our responsibility. e) Product claims. Somia Digital, and not Apple, is responsible for addressing any claim by you or any third party relating to the App or your possession and use of the App, including, without limitation: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; (iii) claims arising under consumer protection, data protection or privacy legislation; and (iv) claims relating to the App's use of the HealthKit framework. f) Third-party intellectual property rights. If a third party claims that the App infringes its intellectual property rights, Somia Digital, and not Apple, will be solely responsible for the investigation, defence, settlement and discharge of that claim. g) Third-party terms. You agree to comply with the applicable terms of any third-party service you use through the App. h) Apple and its subsidiaries are third-party beneficiaries of these Terms and, upon your acceptance, have the right to enforce them against you. i) Legal compliance. You represent that (i) you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and (ii) you are not listed on any US Government list of prohibited or restricted parties. j) Questions and complaints. For any question, complaint or claim relating to the App, contact Somia Digital using the details in §1 and §21.

In the event of any conflict between these Terms and Apple's terms in respect of matters Apple governs (purchase, billing, refunds and distribution), Apple's terms prevail.


5. What Strato is

Strato is a tool for reading, calculating and visualising your training and recovery metrics, and a log of strength workouts and meals.

Specifically, and with your permission, Strato:

a) reads data from Apple Health (HealthKit): heart rate, variability, sleep, activity, weight and any other metrics you have authorised; b) calculates on your device derived, indicative scores (Readiness, Sleep, Strain, Energy, Tension) and the baselines used to compare them; c) stores on your device those scores, the baselines and whatever you log (sessions, meals, notes about your day); d) writes to Apple Health, if you authorise it and always at your request, two things and only two: the strength sessions you complete and the meals you log; e) lets you, if you wish, manually upload a workout to Strava; f) lets you, if you expressly consent, use the Coach and meal identification from a photo, which are powered by artificial intelligence (§7).


6. What Strato is NOT

This section is the most important in the whole document. Read it in full.

6.1 Strato is not a medical device

Strato is NOT a medical device within the meaning of Regulation (EU) 2017/745, and has not undergone any medical conformity assessment and does not carry CE marking as a medical device. It is not designed, manufactured or intended to diagnose, prevent, monitor, predict, prognose, treat or alleviate any disease, injury or disability.

6.2 Strato does not give medical advice

Strato's content — including the scores, the recommendations, the strain estimate, the targets and any text generated by the Coach — is informational and indicative. It does not constitute medical advice, diagnosis, treatment, exercise prescription, nutritional advice or professional advice of any kind, and it does not replace the judgement of a physician, physiotherapist, registered dietitian, qualified trainer or any other qualified professional.

This same notice is permanently visible inside the App.

6.3 What you must do

  • Consult a healthcare professional before starting or substantially changing an exercise programme, especially if you have or have had a medical condition, take medication, are pregnant, or have not exercised for some time.
  • If you have concerning symptoms — chest pain, dizziness, unusual breathlessness, palpitations, sharp pain or anything that feels abnormal — stop and seek medical attention. Do not wait for Strato to tell you: Strato cannot know.
  • Do not use Strato to make clinical decisions, about yourself or anyone else.
  • Your own judgement and your doctor's always prevail over any number the App shows you.

7. The Coach and the artificial intelligence features

7.1 You are talking to a machine

Strato's Coach is an artificial intelligence system, not a person. We say so here and the App itself says so before you interact with it, in compliance with the transparency obligations applicable to AI systems intended to interact with natural persons.

7.2 These features are optional and require your consent

Neither the Coach nor photo-based meal identification turns itself on. We ask for your explicit consent before the first use of each, we explain what is sent, and you can withdraw it at any time. If you do not enable them, the rest of the App works in full.

7.3 What is sent and where it goes

The Privacy Policy sets this out in detail. In short: when you use the Coach, a text summary of your already-calculated scores (0-100) is sent, along with the state of the day you have declared yourself and, if you write one, your question; when you use meal identification, the photograph is sent. The request passes through a server of ours that stores nothing and forwards it to the model provider. We do not retain your questions, the answers, or the photos.

7.4 The Coach gets things wrong

Artificial intelligence systems produce probabilistic answers and can be incomplete, inaccurate or plainly wrong, even when they sound confident. The Coach:

  • does not know you beyond what reaches it at that moment;
  • knows nothing about your medical history, your medication or your injuries, other than what you have written yourself;
  • does not diagnose, cannot do so, and is under explicit instructions not to;
  • is not a professional and its answers are not medical advice (§6.2).

Always weigh any suggestion the Coach makes against your own judgement and, if necessary, a professional, before acting on it. How you use its answers is your decision and your responsibility.

7.5 Meal identification is an estimate

The calories, macronutrients and grams estimated by the photo feature are indicative and editable: you set the final figure. Do not rely on them for any purpose requiring nutritional precision.


8. Your data and where it lives

The detail is in the Privacy Policy. What you need in order to understand this contract is this:

a) Strato has no accounts. There is no sign-up, no password and no profile on any server of ours. b) Your health data is processed and stored on your device. The original Apple Health readings are not written to disk; the calculated scores, the baselines and whatever you log are stored in a local database on your iPhone, which is not synchronised with any server. c) A direct and important consequence: because we hold no copy, if you lose your device, wipe it or uninstall the App, the local data is lost and we cannot recover it. Use your iPhone backup if you want to keep it. d) The only exception to point (b) are the AI features in §7, which you must enable yourself, and the Strava upload, which you initiate yourself.


9. Your obligations

In using Strato, you undertake to:

a) make personal, lawful and diligent use of it, in accordance with these Terms, the law and good faith; b) provide truthful information when you enter it (age, weight, state of the day, meals): Strato's calculations depend on what you put in, and false input gives a false result; c) not use the App if a healthcare professional has advised you not to exercise, or contrary to their instructions; d) not ignore symptoms or medical guidance because a score in the App comes out high or low; e) not decompile, disassemble or reverse-engineer the App, nor attempt to derive its source code, save to the extent mandatorily permitted by articles 100 and 100 bis of the Spanish consolidated Intellectual Property Act; f) not circumvent, disable or tamper with the App's technical measures, including subscription controls, purchase verification or usage limits; g) not make abusive, automated or disproportionate use of the artificial intelligence channel: no bulk or automated requests, no use for content unrelated to the App's purpose, no attempts to extract its system instructions, no attempts to induce it to generate unlawful, offensive or dangerous content, and no use to give medical advice to third parties; h) not enter other people's health data without their consent; i) not resell, rent, assign or sublicense the App or access to Strato Pro, nor share access to it for consideration; j) not interfere with the operation of the App or the associated services, nor attempt to access them without authorisation, nor introduce malicious code.

Breach. If you breach these obligations seriously or repeatedly, we may limit or suspend your access to the server-side features (notably the AI channel) and, where appropriate, terminate these Terms, giving prior notice unless the seriousness or urgency does not allow it. If you have an active subscription and the suspension is not attributable to you, you are entitled to the unused proportional part, which is handled through Apple (§10.4).


10. Strato Pro: the subscription

10.1 What it includes

Strato's principle is: measuring and logging are free; understanding in depth and artificial intelligence are paid. The specific, up-to-date list of what Strato Pro unlocks is shown inside the App before you buy.

10.2 Price, term and renewal

  • The price, currency, length of the period and, if any, the free trial period are shown inside the App before you confirm the purchase and on Strato's App Store listing. Prices are set and displayed by Apple in your country's currency and include applicable taxes.
  • The subscription is an auto-renewing one: it renews for the same period unless you cancel it.
  • Billing is carried out by Apple to the payment method associated with your Apple ID, and renewal is charged within the 24 hours before the end of the current period.
  • If you have a free trial period and do not cancel before it ends, it automatically converts into a paid subscription. Any unused portion of a free trial is forfeited if you purchase the subscription before it ends.

10.3 How to cancel

You cancel it yourself, from your iPhone's Settings (Settings ▸ your name ▸ Subscriptions) or at https://apps.apple.com/account/subscriptions. It must be done at least 24 hours before the current period ends.

We cannot cancel your subscription for you: we have no access to your subscription or to your Apple account. Cancelling does not refund the period already paid: you keep access to Strato Pro until it ends.

Uninstalling the App does not cancel the subscription.

10.4 Refunds

Refunds for purchases made on the App Store are handled by Apple, in accordance with its terms, via https://reportaproblem.apple.com. Somia Digital cannot issue them directly because it is not the party that collects payment.

This does not deprive you of the rights consumer law grants you: if you believe you are entitled to a refund and Apple does not grant it, you may contact us at hola@somia.digital and we will look into it, and in any event you retain the avenues of redress in §20.

10.5 Price changes

If we change the price of a subscription you have already taken out, we will notify you with reasonable advance notice by the means the App Store allows, and the change will not apply until the next renewal. If you do not accept it, you may cancel before it takes effect, without penalty.

10.6 If Strato Pro cannot be verified

If the purchase verification service is unavailable for a reason attributable to us, Strato Pro features stay open: we do not lock you out because of a failure of ours.


11. Right of withdrawal

As a consumer, you have fourteen (14) calendar days to withdraw from a contract for digital content or services, under the Spanish consolidated Consumer Protection Act (TRLGDCU).

Statutory exception: this right does not apply to the supply of digital content not supplied on a tangible medium where performance has begun with your prior express consent and with your acknowledgement that you thereby lose the right of withdrawal (art. 103.m TRLGDCU). By purchasing on the App Store and starting to use Strato Pro immediately, that is the case.

In practice: whether you exercise the right of withdrawal or request a commercial refund, the route is Apple (§10.4), which applies its own policies, often more generous than the statutory minimum. If Apple does not grant your request and you believe you are legally entitled, write to us.


12. Liability

This section limits our liability as far as the law allows, and not a millimetre further. Also read §12.6, which sets out what we never limit.

12.1 The service is provided "as is", with an important qualification

Strato is provided "as is" and "as available". In particular, we do not warrant:

a) the accuracy, precision or completeness of the metrics, scores, estimates, targets, baselines or any other derived value. They are approximate by nature: they are calculated from readings taken by a consumer watch or phone, which have their own margin of error, and the App says so expressly wherever it shows them; b) the accuracy of nutritional estimates, including those produced by photo identification; c) the accuracy, relevance or usefulness of the Coach's answers (§7.4); d) that the App is fit for any particular purpose you may have, especially a clinical, competitive or professional one; e) the uninterrupted or error-free operation of the App or of the third-party services it depends on (Apple Health, App Store, Strava, the hosting and AI model providers).

A qualification that is not mere rhetoric: the "as is" above does not exclude or limit the statutory conformity guarantee for paid digital content and services granted to you by the TRLGDCU (arts. 114 ff., transposing Directive (EU) 2019/770). If Strato Pro does not conform to what we have described, you have the corresponding statutory remedies, and these Terms do not cut them back.

12.2 Your own use

We are not liable for damage arising from your improper use of the App, understood to include at least the following:

a) training against a healthcare professional's advice, or having disregarded their judgement; b) training while injured, ill or symptomatic in circumstances that advise against it; c) ignoring symptoms or warning signs from your body because a score in the App looked favourable; d) making clinical, medication or dietary decisions on the basis of the App or the Coach instead of with a professional; e) entering false or erroneous data that causes the calculations to come out wrong; f) using the App in breach of §9.

In these cases the harm does not stem from the App, but from the decision you took.

12.3 Your device's security and third-party services

Strato is designed so that most of your information never leaves your iPhone. That has a consequence that affects you: the security of that information depends, to a large extent, on the security of your device.

Therefore, and save for gross negligence or wilful misconduct attributable to Somia Digital, we are not liable for:

a) unauthorised access to your data arising from a compromise of your device: loss, theft, lending it to third parties, absence of a passcode, jailbreaking, malware you installed, or backups you manage; b) the compromise of third-party accounts or services outside our sphere of control (your Apple ID, your Strava account, your Wi-Fi network); c) failures, outages or security incidents at the providers the service depends on (Apple, the hosting providers, the AI model providers), beyond the diligence incumbent on us in their selection and supervision; d) events of force majeure or causes not reasonably foreseeable or avoidable: disasters, war, acts of authority, general network or utility outages, or cyber-attacks by third parties exceeding the state of the art in reasonable security measures.

12.4 Third-party content and decisions

We are not liable for the content, policies or practices of third-party sites and services that the App links to or connects with at your request.

12.5 Quantitative cap

To the maximum extent permitted by applicable law, and always subject to the exceptions in §12.6, Somia Digital's total aggregate liability arising out of these Terms or the use of Strato is limited to the greater of: (i) the amount you have paid for Strato Pro in the twelve (12) months preceding the event giving rise to the claim, or (ii) fifty (50) euros.

Nor are we liable, in any case, for loss of profit, loss of sporting or professional opportunities, or indirect or consequential damage that is not a necessary and direct consequence of the breach.

12.6 What we never limit

Nothing in these Terms excludes or limits our liability for:

a) wilful misconduct or gross negligence attributable to Somia Digital. Advance waiver of the action to enforce liability for wilful misconduct is void (art. 1102 of the Spanish Civil Code); b) death or personal injury caused by our conduct. Excluding or limiting this liability would be an unfair and void term (art. 86.2 TRLGDCU); c) the rights mandatorily granted to you by consumer law, including the statutory conformity guarantee (§12.1); d) liability as a data controller under article 82 of Regulation (EU) 2016/679 (GDPR) and Spanish Organic Act 3/2018 (LOPDGDD). No term of this contract deprives you of the right to compensation for data processing that infringes data protection law, nor of the right to lodge a complaint with the supervisory authority; e) any other liability the law declares not excludable or limitable.

If any limitation in this §12 is held void or unenforceable, §18 applies and the remaining limitations stay in force.


13. Data protection

The processing of your personal data is described in the Privacy Policy, available at https://stratofitness.com/privacidad.

As data controller, Somia Digital is liable under the GDPR and the LOPDGDD, and these Terms neither limit nor exclude that liability (§12.6.d). You have the right to access, rectify, erase, object, restrict processing and to data portability by writing to hola@somia.digital, and to lodge a complaint with the Spanish Data Protection Agency (www.aepd.es).


14. Intellectual and industrial property

a) The App is ours. The software, design, interface, texts, graphics, trade marks, logos, calculation algorithms and any other element of Strato belong to Somia Digital or its licensors and are protected by intellectual and industrial property law. These Terms transfer no ownership rights in any of it to you. b) Your content is yours. The sessions, meals, notes and any other content you log in Strato are yours. They are stored on your device and we acquire no ownership right and no exploitation licence over them. When you use the Coach, you authorise us solely to transmit what is necessary to provide that specific feature, at that moment, and nothing else. c) Third-party media. The illustrations and animations in the exercise catalogue belong to their authors and are used with permission; the corresponding attribution is visible on every screen that displays them.


15. Availability, changes and discontinuation

a) We will make reasonable efforts to keep Strato available and working properly, but we do not guarantee uninterrupted availability (§12.1.e). b) We may modify, add or withdraw features to improve the App, fix bugs, comply with legal obligations or adapt to changes in operating systems and third-party services. c) If we withdraw a feature included in Strato Pro and this substantially alters its value, we will notify you with reasonable advance notice and you may cancel the subscription and, where applicable, claim the unused proportional part through the route in §10.4. d) We may discontinue Strato on reasonable advance notice, not less than thirty (30) days if you have an active subscription, and by ceasing to renew it.


16. Term and termination

These Terms remain in force for as long as you use Strato.

You may end them at any time: cancel the subscription (§10.3) and uninstall the App.

We may end them, or suspend your access, in the event of serious or repeated breach of §9, on the terms that section describes.

Termination does not affect the sections that by their nature must survive it: §12 (liability), §14 (intellectual property), §18 (severability) and §20 (law and jurisdiction).


17. Changes to these Terms

We may amend these Terms for legal, technical or business reasons.

We will publish the updated version at https://stratofitness.com with a new "Last updated" date and, if the changes are substantial and affect you as a user, we will notify you before they take effect by a reasonable means (an in-App notice).

If you do not accept the new Terms, your option is to stop using Strato and, where applicable, cancel the subscription before the next renewal. Changes will not apply retroactively to events preceding their entry into force.


18. Severability

If a court or competent authority declares any clause or part of a clause of these Terms void, unfair or unenforceable, it will be deemed not to have been included and the remainder will continue in full force.

The affected clause will be replaced, where possible, by a valid one coming as close as possible to the intended purpose within the limits allowed by consumer protection law. In no case may the voidness of a liability-limiting clause be construed as extending liability beyond what the law provides.


19. Assignment

You may not assign your position under these Terms without our consent.

We may assign ours in the event of restructuring, merger, or sale of the business or its assets, provided that this does not reduce your guarantees as a consumer; we will notify you with reasonable advance notice and, if you do not accept it, you may terminate the Terms and cancel the subscription.


20. Governing law, complaints and jurisdiction

20.1 Governing law

These Terms are governed by Spanish law.

If you are a consumer habitually resident in another Member State of the European Union, this choice does not deprive you of the protection afforded by the mandatory provisions of the law of your country of residence, in accordance with article 6 of Regulation (EC) 593/2008 (Rome I).

20.2 Complaints: talk to us first

If you have a problem, write to us at hola@somia.digital. We will try to resolve it reasonably and quickly. This step is not mandatory and does not deprive you of any right or of any time limit.

20.3 Out-of-court dispute resolution

As a consumer you may turn to:

  • the Municipal Consumer Information Office (OMIC) of your municipality or the consumer affairs service of your autonomous community;
  • the Spanish Consumer Arbitration System (Juntas Arbitrales de Consumo), if both parties submit to it. Somia Digital is not currently a member of the Consumer Arbitration System, so submission would require express acceptance on a case-by-case basis;
  • if the purchase was made on the App Store, Apple's support channel, which is the party handling billing and refunds (§10.4);
  • if you reside in another EU Member State, the European Consumer Centres Network (ECC-Net), which operates in Spain as CEC España;
  • and, in any event and without any prior step, the courts (§20.4).

Note on the European Online Dispute Resolution (ODR) platform: the European Commission platform formerly at ec.europa.eu/consumers/odr ceased to operate on 20 July 2025 and the Regulation that created it has been repealed. These Terms therefore do not refer you to it: linking it would send you to a closed door.

20.4 Jurisdiction

For any dispute, the parties submit to the courts and tribunals having jurisdiction under the law.

Where you are a consumer, that means what articles 17 to 19 of Regulation (EU) 1215/2012 (Brussels I recast) and Spanish consumer law provide: you may only be sued in the courts of your domicile, and you may sue us, at your option, in the courts of your own domicile or in those of Somia Digital's domicile.

These Terms impose no forum. A clause submitting the consumer to a court other than that of their domicile would be unfair and void (art. 90.2 TRLGDCU), and we do not want one.

22. Language

These Terms are published in Catalan, Spanish and English. This English text is provided for convenience. Where you are a consumer resident in Spain, the Spanish version prevails in the event of any discrepancy; where you are a consumer resident elsewhere in the European Union, this does not deprive you of the protection of the mandatory provisions of your own law (§20.1).
