Terms of Service

1. Who may use Zer0

You must be at least 18 years old. By creating an account you confirm that you are, that the information you give us is accurate and that you will keep it up to date. One person may hold one personal account.

2. Not medical advice — your responsibility

By using the Service you acknowledge that:

• Information in the Service, including calorie and nutrient values, AI photo and text estimates, meal plans, presets, reports and AI coach messages, is provided for general information. It can contain errors and is not a substitute for advice from a doctor, registered dietitian or other qualified professional.
• Food allergy and diet filters reduce, but do not remove, the risk of an unsuitable food. Always read product labels and check ingredients yourself.
• You decide how to use the information and you are responsible for evaluating its accuracy and suitability for you.
• If you feel unwell, stop and seek medical help. In an emergency call your local emergency number.

3. The Service

• Food logging, including AI analysis of food photos and text, barcode and database search.
• Nutrition targets, progress, weight and activity tracking, including data you choose to import from Apple Health, Health Connect, Strava, Cronometer, MyFitnessPal or FHIR files.
• An AI coach that answers questions about nutrition and habits.
• Connection with a dietitian or a nutrition centre of your choice (see section 5).

AI features use third-party language and vision models (see the Privacy Policy). Their answers are generated automatically, may be wrong and are not reviewed by a person unless your dietitian reviews them.

4. Your account

Keep your sign-in method (email code, password, Apple or Google account) secure and tell us at once about any unauthorised access. You are responsible for activity under your account. You can delete your account at any time in the app or at c0r.ai/delete-account.

5. Dietitians, nutrition centres and their clients

5.1 If you are a client

When you connect to a dietitian (for example with a pairing code), that dietitian and, if they work in a nutrition centre, authorised staff of that centre can see the data described in the Privacy Policy. You can disconnect at any time; access stops when you do. Dietitians are independent professionals, not our employees or agents. Advice, plans and consultations they give you are their responsibility, and any agreement about their fees is between you and them or their centre.

5.2 If you are a dietitian or a centre ("Professional")

You agree that:

• You act as an independent professional and are solely responsible for the advice, plans and services you provide, including holding any licence or registration your country requires.
• You will tell your clients that Zer0 is an informational tool and will not present its outputs as a diagnosis or as more reliable than they are.
• You will obtain any consent your clients' law requires before inviting them, will access client data only to provide your services, and will keep it confidential. You are responsible for your own compliance with health-data and privacy laws that apply to you.
• Exports you download (PDF, CSV, FHIR) leave the Service under your control and responsibility.
• You are responsible for claims by your clients arising from your services or your use of the Service.

We may check information a Professional provides, but we do not guarantee any Professional's qualifications or the quality of their services.

6. Subscriptions, payments and refunds

Paid plans for individuals are sold through the Apple App Store or Google Play and renew automatically until you cancel in your store account; store refund rules apply. Plans for dietitians and centres are billed through our payment providers and renew automatically until cancelled in the Billing section; access continues to the end of the paid period. Prices and taxes are shown before you pay. We announce price changes in advance and you can cancel before they take effect. Where the law of your country gives you a right to a refund or withdrawal, that right applies.

7. Acceptable use

You must not:

• Use the Service unlawfully, harass anyone, or upload content you have no right to share or that harms others.
• Impersonate any person, or share another person's health data without a lawful basis.
• Access the Service by automated means, scrape it, or copy, resell or redistribute our food database.
• Use content or data from the Service to train, fine-tune or evaluate machine-learning models, or for research or commercial products, without a written licence from us.
• Interfere with the security or operation of the Service, or probe it for vulnerabilities except through responsible disclosure to support@c0r.ai.

8. Your content

You own the photos, logs and notes you add. You give us a non-exclusive, worldwide licence to host, process and display them only to provide and improve the Service for you and for the people you share with. The licence ends when you delete the content or your account, except for copies we must keep by law or that remain for a short time in backups. If you send us feedback or suggestions, we may use them without obligation to you.

9. Third-party services

The Service connects to services we do not control (app stores, payment providers, Apple Health, Health Connect, Strava, Google Calendar and others). Their terms and privacy policies apply to them, and we are not responsible for their availability or content.

10. Communications

We send messages that are needed to run your account (sign-in codes, security notices, billing). Marketing and newsletter emails are sent only if you agree and you can unsubscribe at any time.

11. Changes to the Service and to these Terms

We may change or discontinue features. We will tell you about material changes to these Terms in the app or by email before they take effect; continuing to use the Service afterwards means you accept them. If you do not agree, you can delete your account.

12. Suspension and termination

We may suspend or close an account that breaks these Terms or the law, or that puts other users or the Service at risk. Where reasonable we will tell you why. You can stop using the Service and delete your account at any time.

13. No warranties

TO THE EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, INCLUDING ACCURACY, COMPLETENESS, FITNESS FOR A PARTICULAR PURPOSE OR UNINTERRUPTED OPERATION.

14. Limitation of liability

TO THE EXTENT PERMITTED BY LAW, ERARTA IS NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOSS ARISING FROM RELIANCE ON INFORMATION IN THE SERVICE OR FROM A PROFESSIONAL'S ADVICE. OUR TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO THE AMOUNT YOU PAID US IN THE THREE MONTHS BEFORE THE CLAIM. NOTHING IN THESE TERMS LIMITS LIABILITY THAT CANNOT BE LIMITED BY LAW, INCLUDING FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR YOUR RIGHTS AS A CONSUMER.

15. Indemnity

If you use the Service in breach of these Terms or the law, or, as a Professional, in providing services to your clients, you agree to cover reasonable losses and costs we incur from third-party claims caused by that use, to the extent permitted by law.

16. Governing law and disputes

These Terms are governed by the laws of the United Arab Emirates as applied in the Emirate of Sharjah. Before going to court, please write to us so we can try to resolve the issue. Courts of Sharjah have jurisdiction, without depriving you of the protection of mandatory consumer law of the country where you live.

17. General

These Terms and the Privacy Policy are the whole agreement between you and us about the Service. If a provision is unenforceable, the rest remains in force. Our not enforcing a provision is not a waiver. You may not transfer your rights under these Terms; we may transfer ours to a successor of the Service with notice to you. We are not liable for delays caused by events beyond our reasonable control.
