Allgemeine Geschäftsbedingungen (Terms of Use)

Last updated: 25 October 2026

Welcome to Zura. These Terms of Use ("Terms" or this "Agreement") govern your access to and use of the Zura Health OS mobile application (the "App"), our website at zurahealthos.com (the "Site"), and the related content, features and services (together with the App and Site, the "Services").

The Services are operated by Zura Health UG (haftungsbeschränkt), a limited liability company under German law with its registered office in Kirchseeon, registered in the commercial register of the Local Court (Amtsgericht) of Munich under HRB 316115, business address Heinrich-Egger Straße 8, 85614 Kirchseeon, Germany, represented by its managing directors Mahsa Iraniara and Amir Hossein Zahiri (“Company”, “we”, “us” or “our”). The Company develops Zura in affiliation with the Lehrstuhl für Sport- und Gesundheitsdidaktik at the Technical University of Munich (TUM). The affiliation with TUM is of a scientific and institutional nature; TUM does not assume any contractual obligations or liability under these Terms.

Please read these Terms carefully. They contain important information about your legal rights and obligations, including a wellness and medical disclaimer (Section 3), AI feature limitations (Section 2), subscription and billing terms (Section 6), and a limitation of liability (Section 14).

These Terms form a binding agreement between you and the Company. The Agreement takes effect when you accept these Terms during onboarding or otherwise use the Services. If you do not agree to these Terms, you must not use the Services. Nothing in these Terms excludes or limits rights you have under mandatory consumer-protection law that cannot be excluded or limited by agreement.

1. The Services

Zura is a health, fitness and wellness application. The Services include:

• health and fitness features — food recognition from photos, progress photos and body measurements, AI-generated workout and nutrition plans and recommendations (we adjust workout plans automatically over time, for example each week based on the workouts you log, and may replace a plan with a new one automatically when it ends), cycle tracking, reading the health documents you upload, guided meditation and personal wellness tracking;
• wearable integration, where you choose to connect a wearable device and we import health and activity data through Open Wearables, the wearable integration platform we operate; and
• the Zura AI coach, a conversational AI you can interact with by text or in a live voice conversation, that answers your questions and, on your instruction, can change your workout or nutrition plans, log or delete meals and workouts and set reminders for you. The Zura feed also shows AI-generated summaries of published health research.

We may modify, update or change the Services from time to time. The availability and functionality of third-party services integrated with Zura, including wearable platforms, are governed by those third parties' own terms.

2. Artificial intelligence features

Certain features use artificial intelligence or machine-learning technologies to generate insights, recommendations and other content ("AI-Generated Content"). You acknowledge and agree that:

• AI-Generated Content is produced automatically and may contain errors, inaccuracies or omissions;
• it does not constitute medical advice, diagnosis or treatment and must not be relied on as such;
• we do not guarantee its accuracy, completeness or fitness for any purpose; and
• you should consult a qualified healthcare professional before making any health-related decision, regardless of any AI-Generated Content you receive.

In line with Article 50 of the EU AI Act (Regulation (EU) 2024/1689):

• The Zura coach is an AI system. You are interacting with an AI, not a human.
• We do not use AI to make automated decisions producing legal effects, or similarly significant effects, concerning you within the meaning of Article 22 of the GDPR.
• We do not use biometric data to infer your emotions in order to influence your decisions.

You will not use the AI features to attempt to extract training data, reverse-engineer the underlying models, or generate content that violates these Terms or applicable law. Where AI output relates to health, fitness or nutrition, the Wellness Disclaimer in Section 3 applies.

3. Wellness disclaimer and acknowledgements

By using the Services, you acknowledge and agree that:

• Wellness purposes only. The Services are for general health, fitness and wellness information only. They are not a substitute for professional medical advice, diagnosis or treatment, and nothing in the Services is the practice of medicine, mental-health care, physiotherapy or counselling.
• Not a medical device. Zura is not a medical device under Regulation (EU) 2017/745. The Services do not diagnose, treat, cure or prevent any disease or condition.
• Cycle tracking. Cycle forecasts, phase estimates and ovulation indications in the App are estimates for general wellness and training planning. They are not a method of contraception or a fertility prediction, and you must not rely on them to avoid or to achieve a pregnancy.
• No replacement for professional care. The Services, including all AI-Generated Content, are not a substitute for the advice of your physician or other qualified healthcare professional.
• Consult a professional. Consult a physician before making changes to your sleep, exercise or nutrition. If you experience unexpected, repeating or long-term pain, fatigue or discomfort while using the Services, stop and consult a physician. Using the Services does not create a doctor–patient or other healthcare-professional relationship between you and us.
• Medical conditions. If you tell us about a medical condition, a pregnancy or that you are breastfeeding, the App uses this information to leave out some foods and eating patterns and to adjust some nutrition targets in your plans. These adjustments are general precautions, not medical or dietary treatment, and they do not replace the advice of your physician or a qualified dietitian.
• Medical emergency. If you are experiencing a medical emergency, call 112 (Germany) or your local emergency number immediately. Do not use the Services to seek emergency assistance.

4. Privacy

Your use of the Services is also governed by our Privacy Policy (https://zurahealthos.com/privacy-policy), which explains how we collect, process and use personal data and is incorporated into these Terms by reference. Given the nature of the Services, we process health-related data that may qualify as special categories of personal data within the meaning of Article 9 (1) of the EU General Data Protection Regulation (GDPR). Such data — including body images, wearable data and health details you enter, such as injuries, medical conditions and check-ins — is processed only on the basis of your explicit consent pursuant to Article 9 (2)(a) GDPR. You may withdraw your consent at any time with effect for the future, without affecting the lawfulness of processing carried out before the withdrawal. The details of data processing, your rights as a data subject (including rights of access, rectification, erasure, data portability and the right to lodge a complaint with a supervisory authority), and information about any recipients or categories of recipients are set out in the Privacy Policy. If there is a conflict between these Terms and the Privacy Policy on a matter of personal-data processing, the Privacy Policy prevails.

5. Eligibility and accounts

5.1 Eligibility. To use the Services you must be at least 18 years old. By using the Services, you represent that you meet this age requirement. You further represent that you are not barred from using the Services under applicable law.

5.2 Your account. To use the Services you must create an account using a valid email address and a secure password, or by signing in with Google or Apple. You agree to provide accurate information and keep it up to date. You are responsible for keeping your credentials confidential and for all activity under your account, and you must notify us promptly at info@zurahealthos.com if you suspect unauthorised use. Do not share your credentials, and do not create more than one account without our consent.

6. Subscriptions, billing and cancellation

6.1 Free and paid features. The Services include features available free of charge. We may also offer optional paid subscription plans that unlock additional features. The features included in the free tier and in each paid plan, and the price of each paid plan, are described in the App at the point of purchase.

6.2 How you pay. Paid subscriptions are sold only in the App and are billed through the app store you buy them from:

• purchases made on iOS are processed by Apple through Apple In-App Purchase;
• purchases made on Android are processed by Google through Google Play billing.

Apple's or Google's billing, renewal, refund and family-sharing rules also apply, in addition to these Terms. We do not receive or store your full payment-card number.

6.3 Billing and automatic renewal. Unless stated otherwise at purchase, paid subscriptions are billed in advance for the chosen billing period and renew automatically for successive periods of the same length until cancelled. Before any paid subscription begins, we (or the app store) clearly disclose, in accordance with Article 246a § 1 EGBGB: the price (including all taxes), the billing period, the fact of automatic renewal, the minimum duration of the contract, and the conditions and procedure for cancellation. The payment method on file is charged at the start of each renewal period.

6.4 Cancellation. You may cancel a paid subscription at any time, with effect from the end of the current billing period. You cancel in your Apple or Google account, in the subscription settings of the App Store or Google Play. Cancellation stops future charges; except where required by law, it does not entitle you to a refund of amounts already paid for the current period.

6.5 Right of withdrawal (EU/EEA consumers). If you are a consumer in the EU/EEA, you have a statutory right to withdraw from a paid subscription contract within 14 days of entering into it, without giving reasons (Widerrufsrecht) (§ 312g (1), § 355 BGB). You may exercise the right of withdrawal by sending us a clear declaration (e.g. by email to info@zurahealthos.com or by post) stating your decision to withdraw, or through Apple or Google (see below). You may, but are not required to, use the model withdrawal form we provide below. To meet the withdrawal deadline, it is sufficient that you send the withdrawal declaration before the withdrawal period expires.

Model Withdrawal Form

(If you wish to withdraw from the contract, please fill out this form

and return it.)

— To Zura Health UG (haftungsbeschränkt), Heinrich-Egger Straße 8, 85614 Kirchseeon, Germany, email: info@zurahealthos.com:

— I/we () hereby withdraw from the contract I/we () entered into for the provision of the following service (*)

— Ordered on ()/received on ()

— Name of the consumer(s)

— Address of the consumer(s)

— Signature of the consumer(s) (only for written notifications)

— Date

(*) Delete as appropriate

You can also withdraw through Apple (at reportaproblem.apple.com) or Google (in your Google Play account); their procedures then apply.

6.6 Price changes. We may change subscription prices for future billing periods. We will notify you in text form (Textform) at least four (4) weeks before the new price takes effect. The notification will state the new price, the date on which it takes effect, and your right to cancel the subscription before that date. If you do not cancel before the new price takes effect, the new price applies from your next renewal period. Price increases within four months of the initial subscription are excluded (§ 309 Nr. 1 BGB).

6.7 Taxes. Stated prices include applicable value-added tax (VAT) unless otherwise indicated.

6.8 Refunds. Except where a refund is required by mandatory consumer law or your statutory right of withdrawal, payments are non-refundable. Refunds are handled by Apple or Google under their policies.

7. Your content

7.1 Your content. The Services let you submit text, photos, images, messages, feedback and other content ("Your Content"), including body progress photos, food photos for AI food recognition, health documents you upload, messages with the Zura coach (including transcripts of voice conversations), workout, nutrition and cycle logs, and feedback.

7.2 Ownership and licence. You retain ownership of Your Content. By submitting Your Content, you grant us a non-exclusive, worldwide, royalty-free licence to host, store, process and display Your Content to provide and improve the Services for you, and to improve, secure, analyse and develop the Services using aggregated or de-identified information where permitted by applicable law, in each case in accordance with our Privacy Policy. This licence ends when you delete Your Content or your account, except where retention is required by law or expressly permitted by the Privacy Policy. The processing of personal data within Your Content is governed by the Privacy Policy.

7.3 Your responsibilities. You represent and warrant that you have the rights needed to submit Your Content; that Your Content does not infringe any third party's intellectual-property, privacy or other rights; that any body or identifying image you submit to AI features depicts only yourself; and that Your Content is not unlawful, harmful, harassing, defamatory or otherwise objectionable.

7.4 Feedback. If you voluntarily submit feedback — such as bug reports, feature suggestions, survey responses and general comments — you grant us a non-exclusive, worldwide, royalty-free, perpetual licence to use such feedback to improve the Services. This licence does not extend to personal data within Your Content, which remains governed by the Privacy Policy. For the avoidance of doubt, the foregoing does not affect any rights you may have under mandatory law, including moral rights (Urheberpersönlichkeitsrecht).

8. Acceptable use

When using the Services, you agree not to:

• use the Services for any unlawful purpose or in breach of these Terms;
• submit content that is illegal, harmful, harassing, defamatory or infringing, or that depicts a person other than yourself in images submitted to AI features;
• attempt to circumvent, disable or interfere with security or integrity features;
• reverse-engineer, decompile or attempt to extract source code, AI models or training data, conduct prompt-injection attacks, submit adversarial uploads, or run other adversarial misuse testing against the AI features, except as permitted by mandatory law;
• use bots, scrapers or other automated means to access the Services;
• probe or test the vulnerability of the Services or breach any security or authentication measure;
• access non-public areas of the Services without authorisation;
• impersonate any person or misrepresent your affiliation;
• use the Services to provide medical, nutritional or therapeutic advice to others;
• harass or abuse our personnel; or
• use the Services while driving, operating machinery, or engaged in any other activity that requires your full attention;
• rely on the Services or on AI-Generated Content in a medical emergency, or as a substitute for emergency care — in a medical emergency, call your local emergency number (in Germany, 112);
• use the Services to make clinical, diagnostic or treatment decisions, or as a substitute for professional medical supervision;
• upload another person's body image, medical records, health data or other personal data without that person's informed consent — the App is for your own data only;
• use the Services in any way that could damage, disable or overburden our systems or those of our providers.

We may suspend or terminate access if we reasonably believe you have breached this Section. Where reasonably possible, we will notify you.

9. Intellectual property

All rights, title and interest in the Services — including software, AI models, designs, content, trademarks and logos (the "Zura Materials") — belong to us or our licensors and are protected by intellectual-property laws. Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the App on your personal devices for your personal, non-commercial use. Nothing else in these Terms grants you any right in our intellectual property. This licence ends on termination of your account or these Terms, after which you must stop using the Zura Materials and delete the App.

10. Third-party services and links

The Services may link to or interoperate with services operated by third parties ("Third-Party Services"), including wearable platforms, sign-in providers, app stores and our service providers. We do not control Third-Party Services and are not responsible for them. They have their own terms and privacy policies, and your use of them is at your own risk and governed by those terms.

Some videos in the App, such as meditation sessions, some exercise demonstrations and videos in the Zura feed, are played through YouTube's embedded player. By using these features, you agree to be bound by the YouTube Terms of Service (https://www.youtube.com/t/terms).

11. Service availability and modifications

We will use reasonable efforts to keep the Services available, but we do not guarantee uninterrupted or error-free operation. The Services may be temporarily unavailable for maintenance, updates, technical issues, or events beyond our reasonable control (force majeure). We may modify, suspend or discontinue features of the Services to the extent this is reasonable for you, taking into account our legitimate interests (e.g. security, legal compliance, technical improvements) and your interests in the continuity of the Services (§ 308 Nr. 4 BGB). Where a change materially reduces the functionality of a paid feature, we will notify you in text form at least four (4) weeks in advance and inform you of your right to terminate the subscription; if you bought it through Apple or Google, you can ask them for a refund for the remaining period, and we will support your request. We will not discontinue essential features of a paid subscription during a current billing period without offering a commensurate alternative or supporting your refund request to Apple or Google.

12. Suspension and termination

12.1 By you. You may stop using the Services at any time and may delete your account through the App. Your account is then deactivated immediately and deleted permanently after a grace period of 90 days; until then, you can cancel the deletion by signing in to the App again and choosing to restore your account. The handling of your personal data after termination is described in the Privacy Policy.

12.2 By us. We may suspend or terminate your access if you materially or repeatedly breach these Terms; if continued provision would expose us to legal or regulatory risk; for technical or security reasons that make provision impracticable; or if you have misrepresented your eligibility (including age). Where reasonably possible we will give reasonable advance notice. We will not terminate your account arbitrarily or in retaliation for the lawful exercise of your rights, including your data-subject rights.

12.3 Effect of termination. On termination your right to use the Services ends. Provisions that by their nature should survive — including intellectual property, disclaimers, limitation of liability, and governing law — continue to apply. Your personal data is handled in accordance with the Privacy Policy. If you have a paid subscription, termination is handled in line with Section 6.

13. Disclaimers

To the maximum extent permitted by applicable law, and without limiting any rights that cannot be excluded under mandatory consumer law, subject to your mandatory statutory rights — including, without limitation, your rights under §§ 327 to 327u BGB regarding the conformity of digital products and services — the Services are provided on an "as is" and "as available" basis. We do not make any representations or warranties beyond what is required by mandatory law that the Services will meet your individual requirements; that they will be uninterrupted, timely, secure or error-free; or that defects will be corrected within a specific timeframe. In particular, AI-Generated Content (including food analyses, workout or nutrition recommendations, summaries in the Zura feed, and Zura responses) is generated automatically based on statistical models and may contain errors, inaccuracies or omissions. Estimates that the App calculates from your own entries, measurements or connected devices, such as body-fat, fitness-age or cycle estimates, are approximations and may also be inaccurate. AI-Generated Content does not constitute professional advice of any kind. Your statutory rights as a consumer, including rights to cure, price reduction and termination under §§ 327 ff. BGB, remain unaffected.

14. Limitation of liability

This Section sets out the limits of our liability. It follows the common pattern for German consumer contracts and is to be read subject to mandatory law.

14.1 We are liable to you in all cases of contractual and non-contractual liability for willful misconduct and gross negligence in accordance with the provisions of law.

14.2 In all other cases—unless otherwise provided in paragraph 3—we are liable only for a breach of a contractual obligation whose fulfillment is essential for the proper performance of the contract and on whose compliance you, as the customer, may reasonably rely (a so-called cardinal obligation), and such liability is limited to compensation for foreseeable and typical damages. In all other cases, our liability is excluded, subject to the provision in paragraph 14.3.

14.3 Our liability for damages resulting from injury to life, limb, or health, and under the Product Liability Act, remains unaffected by the above limitations and exclusions of liability.

14.4 AI output. Subject to Sections 14.1 and 14.3, we are not liable for loss arising from your reliance on AI-Generated Content or other informational output of the Services contrary to the disclaimers in Sections 2 and 3.

The above limitations also apply in favour of our managing directors, employees and other personnel, and our vicarious agents (Erfüllungsgehilfen), including our service providers.

15. Indemnification

To the extent permitted by applicable law, you agree to indemnify and hold the Company harmless from reasonable third-party claims, losses and reasonable expenses (including reasonable legal fees) arising from (a) Your Content that infringes a third party’s rights, (b) your culpable breach of these Terms, or (c) your intentional or grossly negligent misuse of the Services. This obligation applies only to the extent that the claim is attributable to your fault (Verschulden). This Section does not apply to the extent a claim arises from our own breach or negligence, and does not limit your mandatory consumer rights. Nothing in this Section imposes on you a duty to indemnify that goes beyond what would apply under statutory law.

16. Changes to these Terms

We may amend these Terms with effect for the future if there is a valid reason for the amendment (e.g. changes in legislation, court rulings, technical developments, or the introduction of new features). We will notify you of any material amendment in text form (Textform) at least six (6) weeks before the proposed effective date. The notification will describe the changes, state the effective date, and inform you of your right to object and to terminate the contract. If you do not object to the amendment within the notice period, the amended Terms take effect on the stated date. If you object, the existing Terms continue to apply, and either party may terminate the contract with effect from the date on which the amended Terms would have taken effect. We will specifically inform you about these consequences (right to object, deadline, and termination right) in the amendment notification.

17. Governing law and dispute resolution

These Terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-laws rules and the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of habitual residence.

The Company is based in Munich, Germany. To the extent permitted by law, the courts of Munich have jurisdiction for disputes with users who are merchants or do not have a general place of jurisdiction in Germany. If you are a consumer, you may also bring proceedings in the courts of your place of residence, and we may bring proceedings against you only there.

We are not obliged to, and do not currently, participate in dispute-resolution proceedings before a consumer arbitration board (Verbraucherschlichtungsstelle) pursuant to § 36 VSBG. We are, however, required to inform you of this fact.

18. Apple App Store — additional terms

If you download the App from the Apple App Store, the following additional terms apply, and you acknowledge that:

• these Terms are between you and the Company only, not with Apple Distribution International Limited, Hollyhill Industrial Estate, Hollyhill, Cork, Republic of Ireland (“Apple”), and Apple is not responsible for the App or its content;
• your licence to use the App under Section 9 is limited to a non-transferable licence to use the App on Apple-branded products that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may also be accessed and used by other accounts associated with you through Family Sharing or volume purchasing;
• Apple has no obligation to provide maintenance or support for the App;
• any questions, complaints or claims relating to the App are to be directed to the Company at the contact details in Section 21, not to Apple;
• in the event the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation for the App;
• Apple is not responsible for addressing any claims by you or any third party relating to the App or your possession and use of it, including product-liability claims, claims that the App fails to conform to any applicable legal or regulatory requirement, and claims arising under consumer-protection, privacy or similar legislation, including in connection with the App's use of Apple HealthKit;
• if a third party claims that the App or your possession and use of it infringes that third party's intellectual-property rights, the Company, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim;
• Apple, and Apple's subsidiaries, are third-party beneficiaries of these Terms and may enforce them against you;
• you represent that you are not located in a country subject to a U.S. Government embargo or designated as terrorist-supporting, and that you are not on any U.S. restricted-party list; and
• you must comply with any applicable third-party terms of agreement when using the App, for example your mobile data service agreement.

19. Google Play — additional terms

If you download the App from the Google Play Store, your use is also subject to the Google Play Terms of Service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (“Google”). Google is not a party to these Terms and is not responsible for the App.

20. Miscellaneous

If any provision of these Terms is found unenforceable, the remaining provisions remain in effect; the unenforceable provision shall be replaced by a provision that comes closest to the economic purpose of the unenforceable provision in a legally permissible manner. Our failure to enforce a provision is not a waiver of it. You may not assign your rights or obligations under these Terms without our prior written consent; we may assign them to a successor entity, with notice to you in text form at least six (6) weeks before the assignment takes effect. These Terms, together with the Privacy Policy, are the entire agreement between you and us regarding the Services and supersede all prior understandings.
