This information is provided in compliance with Article 10 of the Spanish Law 34/2002 on Information Society Services and Electronic Commerce (LSSI-CE). See also our Legal Notice.
Throughout these Terms, "we", "us" and "our" refer to the provider above; "you" refers to the person using the Service.
2.1 HAVYT is a wellness, fitness and self-tracking application. It helps you plan and log workouts, track recovery, sleep, nutrition, symptoms (including symptoms associated with Ankylosing Spondylitis and chronic pain), menstrual cycle information, and habits, and it surfaces patterns and educational information based on the data you choose to log.
2.2 Everything HAVYT shows you — including scores, readiness indicators, "flare outlook" states, pattern observations, AI coaching messages, generated training plans, nutrition estimates and reports — is informational and educational only. It reflects the data you and your connected devices have provided, processed by general-purpose software. It is:
2.3 The "Doctor Report" feature produces a summary of your own logged data to support a conversation with your clinician. It is generated on your device, may contain errors, and is not a medical record. Review it before sharing it.
2.4 If you have — or suspect you have — a medical condition (including Ankylosing Spondylitis or any other inflammatory, cardiovascular, metabolic or musculoskeletal condition), are pregnant or postpartum, or are recovering from injury or surgery, consult a healthcare professional before starting or changing an exercise or nutrition routine, regardless of what the app suggests. See our Medical Disclaimer.
3.1 You may use the Service only if you are at least 16 years old. If the law where you live requires permission from a parent or legal guardian for you to use the Service or agree to these Terms, you may use it only with that permission.
3.2 We use the date of birth you provide during onboarding to verify eligibility. If we become aware that an account belongs to a person under 16, we may suspend access and delete the account in accordance with Section 21 and our Privacy Policy.
3.3 The Service is directed at consumers in the European Union. If you use it from elsewhere, you are responsible for compliance with your local laws.
4.1 By creating an account or using the Service, you agree to these Terms, our Privacy Policy and our health and safety disclaimers (see the Medical Disclaimer, Fitness Disclaimer, Nutrition Disclaimer, AI Disclaimer and Wearables Disclaimer for how we handle your data and health-related limitations in detail).
4.2 We record which version of the legal documents you accepted, when, and how (our in-app acceptance record system). This record is kept as proof of consent and acceptance.
4.3 We may update these Terms, for example when we add features, when the law changes, or to correct or clarify provisions. For material changes, we will notify you in the app and/or by email in advance and, where the change affects your core rights or obligations, ask you to re-accept the updated Terms in the app before continuing to use affected features. Each version is numbered and dated, and previous versions are available on request.
4.4 If you do not agree to updated Terms, you may stop using the Service and delete your account at any time (see our Data & Account Deletion Policy). Material changes do not apply retroactively, and no change will deprive you of rights that mandatory consumer law grants you.
5.1 You register with an email address and password. You must provide accurate information and keep it up to date.
5.2 Keep your credentials confidential. You are responsible for activity under your account unless it results from a security failure on our side. Tell us immediately at support@havyt.app if you suspect unauthorized access.
5.3 One account per person. Accounts are personal and non-transferable.
6.1 HAVYT's insights are only as good as the data behind them. You are responsible for the accuracy and completeness of the information you log — including health conditions, injuries, implants, allergies, medications, symptoms and body metrics. Inaccurate or incomplete entries can lead to unsuitable suggestions (for example, a training plan that does not account for an injury you did not log).
6.2 You should log honestly for your own benefit, but you are never obliged to enter any particular health information. Features that need specific data simply work less well, or not at all, without it.
6.3 If you enter information about another person (which the Service is not designed for), you are responsible for having the right to do so.
7.1 Stop and seek help. Stop exercising immediately and contact emergency services (112 in the EU) or seek urgent medical care if you experience any of the following, whether during a workout or otherwise:
7.2 The app may show safety information when your logged symptoms match patterns that can be serious (for example, certain eye symptoms). These messages are general safety information urging you to seek professional evaluation; they are not a diagnosis, and their absence is not an all-clear. Never delay seeking care because the app has not raised a flag.
7.3 You agree to use your own judgment, follow the advice of your healthcare professionals over anything in the app, warm up appropriately, use equipment you can handle safely, and not train through symptoms that a reasonable person would treat as warning signs.
8.1 Nothing in the Service — including AI chat and voice responses, generated plans, readiness or flare indicators, pattern observations, reports, notifications or educational content — constitutes medical, diagnostic, therapeutic, pharmaceutical or nutritional-therapy advice.
8.2 HAVYT does not diagnose conditions, predict disease, recommend, adjust or discontinue medication, or make clinical assessments. Where the app describes tools associated with medical practice (for example, the BASDAI questionnaire), it does so for personal tracking only, using the published public scoring, and the results are not a diagnosis or measure requiring clinical interpretation by the app.
8.3 Always consult a qualified professional for medical questions, and never disregard or delay professional advice because of something you read or received in HAVYT. See our Medical Disclaimer.
9.1 Parts of the Service use artificial intelligence (large language models operated by a third-party provider — see our Privacy Policy and AI Disclaimer for details on the provider and the data involved). This includes the "Emelie" chat and voice coach, generated training plans, photo-based estimates and short report summaries.
9.2 You acknowledge that AI output:
9.3 We design AI features to be hedged, grounded in your logged data, and to point you toward professionals for medical questions — but we cannot guarantee any individual output. Use AI features as a convenience, and verify anything important.
9.4 You must not attempt to manipulate AI features into producing medical advice, harmful instructions or content that violates Section 15 or our Acceptable Use Policy.
10.1 You can connect Apple Health as a data source. HAVYT has no direct connection to wearable services such as Oura, WHOOP, Huawei Health, Garmin, Fitbit or Polar; their data can reach HAVYT only if you choose to share it into Apple Health, and what arrives may be incomplete. Those devices and services are provided by third parties under their own terms; we do not control their accuracy, availability or APIs.
10.2 Wearable-derived metrics (heart rate, HRV, sleep stages, SpO2, respiratory rate, temperature, etc.) are consumer estimates, not clinical measurements. Readings can be missing, delayed, duplicated or wrong, and any HAVYT feature built on them (readiness, body-signal monitoring, check-in prefill) inherits those limitations. See our Wearables Disclaimer.
10.3 Third-party providers may change or discontinue their integrations at any time; we may need to modify or withdraw an integration accordingly (see Section 17).
10.4 If you grant Apple Health write permission, HAVYT may save compatible information that you created in HAVYT. You remain in control of those permissions in Apple's Health settings. HAVYT's scores, flare outlook, BASDAI tracking and other derived wellness concepts are not medical records and are not written into unrelated Apple Health fields.
11.1 Physical exercise carries inherent risks, including muscle soreness, strains, sprains, falls, aggravation of existing conditions and, rarely, serious injury. You participate at your own risk and are responsible for exercising within your abilities, in a safe environment, with equipment in good condition. See our Fitness Disclaimer.
11.2 Generated plans and intensity guidance are based on the preferences, equipment, experience and health information you provided. They are general fitness programming, not physiotherapy or rehabilitation. When in doubt — especially with a flare, injury, illness or new pain — do less, not more, and consult a professional.
11.3 Nothing in this Section excludes or limits our liability where the law does not allow it (see Section 20).
12.1 Food logging, barcode lookups, photo-based meal estimates, calorie/macro figures and nutrition-related insights are estimates for general awareness, drawn from public and third-party food databases and automated image analysis. They can be materially inaccurate for any given food or portion. See our Nutrition Disclaimer.
12.2 HAVYT is not a medical-nutrition or allergy-safety tool. Allergy information you log is used to filter suggestions as a convenience, but you must always verify ingredients yourself — never rely on the app to protect you from an allergen. Nutrition features are not suitable as the basis for managing diabetes, eating disorders, or any medically supervised diet.
13.1 "User Content" means content you create or upload in the Service: notes and free-text entries, progress and meal photos, stories, shared goals, streaks, challenge participation, messages to support, avatar images, and similar material. You keep all rights you hold in your User Content.
13.2 You grant us a non-exclusive, worldwide, royalty-free license to host, store, reproduce, process, adapt (e.g. resize, transcode), and display your User Content solely to the extent needed to operate the Service for you and the people you choose to share with — for example, storing your photos, showing your shared streak to a friend, or displaying your story for its 24-hour window. This license ends when the content or your account is deleted, except for the limited retention described in our Data & Account Deletion Policy. We do not use your User Content for advertising and we do not sell it.
13.3 Content you mark as shared (stories, shared goals/streaks, challenges) is visible to the audience the sharing feature defines (e.g. accepted friends). Think before sharing health-related content; our Acceptable Use Policy governs how everyone must treat other users' shared information.
13.4 You are responsible for your User Content. It must not infringe others' rights or violate Section 15 or the Acceptable Use Policy. We may remove content that does (see Section 21).
14.1 We grant you a personal, non-exclusive, non-transferable, revocable license to install and use the HAVYT app on devices you own or control, for your personal, non-commercial use, in accordance with these Terms and any applicable app-store rules (including Apple's usage rules for apps obtained from the App Store).
14.2 If you obtained the app through the Apple App Store: Apple is not a party to these Terms, has no obligation to provide maintenance or support for the app, and is not responsible for addressing claims relating to the app; however, Apple and its subsidiaries are third-party beneficiaries of this Section and may enforce it against you.
You must not:
HAVYT may provide a free monthly AI allowance and offer optional packs of consumable AI credits as one-time purchases. These packs are not subscriptions, do not auto-renew and do not create a free trial. Prices, fulfilment, refunds and mandatory consumer rights are governed by our AI Credits, Billing & Refund Policy, which forms part of these Terms. Purchases are processed by Apple through the App Store; we do not receive your payment-card details.
17.1 We aim to keep the Service available and reliable, but we do not guarantee uninterrupted or error-free operation. The Service may be temporarily unavailable due to maintenance, updates, or failures of networks, hosting or third-party providers.
17.2 HAVYT is an evolving product. We may add, change or remove features. A change will not retroactively remove AI credits already validly added to your account without the remedy required by mandatory consumer law. Your statutory conformity remedies for digital content and services, including Directive (EU) 2019/770 as implemented in Spain (TRLGDCU arts. 115 ff.), remain unaffected.
17.3 The app may require updates to keep working. We will provide updates required by mandatory law for the period reasonably expected for the relevant digital service.
17.4 Back up anything important. While we take care of your data (see the Privacy Policy and Data & Account Deletion Policy), no system is immune to loss, and self-tracking data is not a system of record for medical purposes.
18.1 The Service relies on third-party providers (hosting, AI processing, email delivery, purchase validation, weather and food databases, map tiles, wearable platforms). Their identity and role in processing your data are listed in the Privacy Policy.
18.2 Where the Service links to or interoperates with third-party services (e.g. Apple Health, wearable vendors, Open Food Facts), your use of those services is governed by their own terms and privacy policies. We are not responsible for third-party services, but this does not limit our own statutory responsibility for the Service we provide.
19.1 The Service — including the app, its design, code, text, graphics, the HAVYT name and logo, exercise content, and the structure and curation of our databases — is owned by us or our licensors and is protected by intellectual-property laws. Except for the license in Section 14 and your rights in your own User Content and personal data, no rights are transferred to you.
19.2 Feedback you voluntarily send us about the Service may be used by us to improve it, without obligation to you.
20.1 What we are always liable for. Nothing in these Terms excludes or limits our liability for:
20.2 What we are liable for in other cases. Subject to 20.1, in cases of ordinary negligence we are liable only for breach of obligations essential to the contract (obligations whose fulfilment you may reasonably rely on for the contract to make sense), and then only for foreseeable damage typical for this type of service.
20.3 What we are not liable for. Subject to 20.1, we are not liable for:
20.4 The Service is provided for personal, non-commercial use; we accept no liability for business losses.
20.5 No unfair indemnity. These Terms do not require you, as a consumer, to indemnify us or hold us harmless. You remain responsible under general law for damage you cause — nothing more.
21.1 By you. You may stop using the Service at any time and delete your account in-app (Settings → Delete Account) — see the Data & Account Deletion Policy. Account deletion permanently removes the account-linked AI-credit balance after the deletion process described there. Consumable credit packs are not subscriptions and there is nothing to cancel.
21.2 By us. We may suspend or terminate your account, with notice stating the reason, if:
Where the breach is severe (e.g. safety threats, illegal content), we may suspend immediately and give reasons afterwards. You can contest any enforcement decision by emailing support@havyt.app; see the appeal process in the Acceptable Use Policy.
21.3 We may terminate the Service as a whole, or free features, with reasonable advance notice. If termination prevents use of purchased credits, we will provide the remedy required by mandatory consumer law and the AI Credits, Billing & Refund Policy.
21.4 Upon termination, Sections that by their nature should survive (including the last sentence of 13.2, and Sections 19, 20 and 22–24) survive.
22.1 These Terms are governed by Spanish law.
22.2 Consumers keep their protections. If you are a consumer habitually resident in the EU/EEA, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of residence (Art. 6(2) Rome I Regulation), and you may bring proceedings — and may only be sued — in the courts of your own country of residence (Arts. 17–19 of the Brussels I recast Regulation (EU) 1215/2012).
22.3 For non-consumers, the courts of Palma, Illes Balears, Spain have exclusive jurisdiction.
23.1 Please contact us first at support@havyt.app — we take complaints seriously and aim to resolve them directly. Spanish consumers may also request official complaint forms (hojas de reclamaciones) as provided by regional consumer regulations.
23.2 You may also have recourse to consumer arbitration (Sistema Arbitral de Consumo), to other alternative dispute resolution (ADR) bodies, or to the consumer authorities of your country of residence.
23.3 The former EU Online Dispute Resolution (ODR) platform has been discontinued by the EU. If you have a complaint, please raise it with us directly at support@havyt.app; you may also contact the Spanish consumer authorities or the consumer-protection and ADR bodies available in your country of residence.
24.1 If a provision of these Terms is invalid, the remainder stays in force; the invalid provision is replaced by the applicable statutory rule.
24.2 We may assign this agreement to a successor of the HAVYT business; your rights are unaffected and you may terminate if you object. You may not assign your account.
24.3 These Terms, together with the documents they reference (Privacy Policy, the health and safety disclaimers, AI Credits, Billing & Refund Policy, Data & Account Deletion Policy, Acceptable Use Policy), are the entire agreement for the Service.
24.4 Language. These Terms are drafted in English. Translations may be provided for convenience; if a Spanish version is published, it will state its relationship to the English text. No translation deprives you of rights under mandatory law.
