Zeno – Terms and Conditions of Use

Last updated: 12 May 2026

These Terms and Conditions of Use ("Terms") govern your access to and use of the Zeno mobile application, website, and related services (together, the "Service"), which are provided by Zeno AI Limited, a company incorporated in Hong Kong ("Zeno", "we", "us", or "our").

By creating an account, accessing, or using the Service, you agree to be bound by these Terms. If you do not agree to these Terms, you must not use the Service.

These Terms apply to users worldwide, to the maximum extent permitted by the laws of your country of residence.

1. Who We Are

Zeno AI Limited is a Hong Kong–incorporated company that provides an AI-powered self-reflection and mental-wellness companion. The Service is designed to help you explore your thoughts, emotions, habits, and patterns over time.

Our registered details and contact information are set out in Section 21 (Contact Us).

2. Eligibility and Minimum Age

2.1 Minimum age. You may use the Service only if:

• you are at least 17 years old, and
• you have the legal capacity to enter into a binding agreement in your country of residence.

2.2 Under 18. If you are under 18, you must have the permission of a parent or legal guardian to use the Service, and they must agree to these Terms on your behalf.

3. Description of the Service

3.1 Purpose. Zeno is an AI-powered self-reflection companion. It may:

• respond to your messages;
• provide reflections, summaries, and insights on your entries and check-ins; and
• help you notice patterns over time (for example, around sleep, mood, or habits).

3.2 No guarantees. We do not promise any particular outcome from using the Service, including but not limited to improvements in mental health, mood, or behaviour. Your use of the Service is voluntary and at your own discretion.

3.3 Changes and updates. The Service will evolve over time. We may add, remove, or modify features from time to time (see Section 18).

4. Zeno Is Not a Therapist, Clinician, or Professional Advisor

4.1 No clinical service. The Service, including all messages, prompts, and responses generated by Zeno (the AI), is not:

• psychotherapy, counselling, psychiatry, psychology, or any form of therapy;
• medical advice or treatment;
• a mental health, medical, or healthcare service;
• legal, financial, or other professional advice.

4.2 No professional relationship. Your use of the Service does not create a therapist–client, doctor–patient, or any other professional–client relationship between you and Zeno AI Limited or any person associated with us.

4.3 No diagnosis or treatment. The Service does not:

• diagnose, prevent, or treat any medical, psychiatric, or psychological condition;
• prescribe medication or recommend changes to medication;
• provide any clinical assessment or formal risk evaluation.

4.4 Informational and reflective only. Any suggestions, reflections, or interpretations from the Service are for general informational and reflective purposes only. They are not a substitute for your own judgment or for advice from qualified professionals.

4.5 No replacement for professional support. You agree that you will not rely on the Service as a replacement for:

• therapy or counselling;
• medical or psychiatric care; or
• other professional services.

You remain responsible for deciding when to seek help from qualified professionals.

5. Crisis, Self-Harm, and Safety

5.1 Not an emergency or crisis service. The Service is not designed for emergencies. It does not provide real-time monitoring or crisis intervention, and we cannot guarantee that any message will be seen or responded to within any particular time.

5.2 If you are in crisis. If you:

• feel you might harm yourself or someone else;
• are in any kind of immediate danger; or
• are experiencing a medical or psychiatric emergency,

you must immediately contact:

• your local emergency services;
• a crisis hotline or helpline in your country; or
• a licensed mental health or medical professional.

Do not rely on Zeno or any output from the Service in these situations.

5.3 No duty to intervene. We do not have a duty to monitor user content or activity, to contact emergency services, or to intervene in any crisis or safety situation. You are responsible for seeking help when needed.

6. Registration, Accounts, and Security

6.1 Account creation. To access certain features, you may need to create an account and provide accurate, current information (such as an email address). You agree to keep this information up to date.

6.2 Account security. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. If you suspect unauthorised access or a security breach, you must notify us promptly.

6.3 One account per person. You must not sell, transfer, or share your account with another person.

7. User Content

7.1 User Content. You may submit text and other content to the Service, including messages, journal entries, check-ins, ratings, and reflections ("User Content").

7.2 Ownership of User Content. As between you and us, you retain ownership of your User Content. These Terms do not transfer ownership of your User Content to Zeno.

7.3 Licence to Zeno. By using the Service, you grant Zeno a limited, worldwide, non-exclusive, royalty-free licence to host, store, process, and display your User Content solely:

• to provide the Service to you (including generating responses, insights, and reports);
• to operate, maintain, secure, and debug the Service.

We do not use your User Content to train, fine-tune, or develop AI models — ours or those of any third party. Any improvements we make to the Service are derived from Technical Information (such as anonymised usage analytics and crash logs), not from the content of your reflections, conversations, or journal entries.

Processing of User Content as described above is governed by our Privacy Policy and, where applicable under GDPR or similar laws, requires your explicit consent. Details of how we handle your data and the legal bases we rely on are set out in our Privacy Policy.

7.4 Responsibility for User Content. You are solely responsible for your User Content and for ensuring that it:

• does not violate any law, regulation, or third-party rights; and
• is appropriate for the Service.

8. Privacy and Data Use

8.1 Privacy Policy. Our Privacy Policy explains how we collect, use, store, and protect your personal data. It is an integral part of these Terms, and by using the Service, you agree to our handling of data as described there.

8.2 No sale of personal data. We do not sell your personal data to third parties. We may share data with trusted service providers who process data on our behalf (for example, hosting providers, our AI infrastructure provider, analytics services, and customer support tools), subject to appropriate contractual safeguards.

8.3 Data rights. To the extent required by applicable law and as described in our Privacy Policy, you may have rights to:

• access your data;
• request correction or deletion; and
• export certain information.

The availability of these rights may depend on your country of residence and the legal basis on which data is processed.

9. Acceptable Use

You agree that you will not use the Service to:

• a. violate any applicable law, regulation, or court order; b. harass, threaten, abuse, or harm others; c. promote self-harm, suicide, or violence; d. generate or distribute content that is hateful, discriminatory, or illegal; e. share or upload content that infringes the intellectual property, privacy, or other rights of third parties; f. impersonate any person or misrepresent your identity; g. introduce viruses, malware, or other malicious code; h. interfere with or disrupt the operation of the Service or any associated systems; i. attempt to gain unauthorised access to accounts, networks, or systems; j. use the Service for high-risk activities where errors could result in death, personal injury, or serious environmental or property damage (for example, medical decision-making, emergency response, aviation or critical infrastructure control); k. attempt to reverse engineer, decompile, or discover the underlying code, models, or algorithms of the Service except to the extent permitted by law; l. bypass, "jailbreak", disable, or attempt to circumvent any safety filters, technical limitations, or usage restrictions; or m. prompt or coerce the Service to produce content that is deliberately harmful, abusive, illegal, or clearly outside its intended use as a mental-wellness companion.

10. Jailbreaking and Manipulated Use

10.1 User responsibility. If you attempt to "jailbreak" the Service, circumvent safety systems, or intentionally cause the Service to behave in ways that are inconsistent with its intended design (for example, by forcing it to act as a harmful, abusive, or unfiltered model), you do so at your own risk.

10.2 No liability for manipulated outputs. To the maximum extent permitted by law, we will not be responsible or liable for:

• any content generated when you intentionally bypass or attempt to bypass safety mechanisms; or
• any actions you take, or fail to take, in reliance on such content.

You remain fully responsible for your behaviour and for any consequences arising from your use of the Service in this way.

11. AI Outputs and Limitations

11.1 Nature of AI. The Service uses artificial intelligence and machine learning. As a result, responses and insights may:

• be inaccurate, incomplete, or out-of-date;
• reflect biases present in the underlying data;
• be inappropriate, offensive, or not aligned with your values or expectations.

11.2 No guarantee of accuracy. We do not guarantee that outputs from the Service are correct, complete, reliable, or suitable for any particular purpose.

11.3 Your responsibility. You agree that:

• you will not treat outputs as a sole source of truth or professional advice;
• you will exercise your own judgment and, where appropriate, obtain professional advice before acting on anything generated by the Service;
• you will not rely on the Service's outputs as a substitute for professional advice on important decisions about your health, finances, or legal matters.

12. Intellectual Property

12.1 Our rights. The Service, including all software, interfaces, designs, text (excluding User Content), images, logos, trademarks, and other materials, is owned or licensed by Zeno and is protected by intellectual property and other laws.

12.2 Licence to use the Service. Subject to your compliance with these Terms, we grant you a limited, revocable, non-exclusive, non-transferable licence to use the Service for your personal, non-commercial purposes.

12.3 Restrictions. Except as expressly permitted by these Terms or applicable law, you may not:

• copy, modify, distribute, sell, lease, or create derivative works from the Service; or
• remove, obscure, or alter any copyright, trademark, or other proprietary notices.

13. App Stores, Billing, and Subscriptions

13.1 App store providers. If you download the app from the Apple App Store or Google Play Store, your use of the app may also be governed by the terms and policies of Apple or Google, respectively. In case of conflict, their terms may apply to billing and subscription management.

13.2 Free trial. New users are offered a seven (7) day free trial of the Service. The free trial is subject to a usage limit of 300,000 tokens (a measure of AI-generated text). If you reach this usage limit before the seven days are up, your free trial period ends at that point. To continue using the Service after the trial period ends (whether by time or by usage limit), you will need to subscribe to a paid plan.

13.3 Subscriptions. After the free trial, continued use of the Service requires a paid subscription:

We offer monthly and annual subscription plans.

Subscription terms (such as duration and price) will be displayed at the point of purchase.

Unless stated otherwise, subscriptions automatically renew at the end of each billing period until cancelled.

13.4 Billing and refunds via app stores. Where payment is handled by Apple or Google:

• billing, renewals, and cancellations are managed through your app store account;
• any refunds are subject to the relevant app store's policies;
• we may not be able to process refunds directly.

13.5 Taxes. You are responsible for any applicable taxes associated with purchases made through the Service.

14. Third-Party Services

The Service may include links to, or integrations with, third-party websites, applications, or services.

We do not control and are not responsible for third-party services, their content, or their privacy practices.

Your use of third-party services is governed by their own terms and policies.

We are not liable for any loss or damage arising from your use of third-party services.

15. Termination and Suspension

15.1 Your right to stop using the Service. You may stop using the Service and delete your account at any time.

15.2 Our right to suspend or terminate. We may suspend or terminate your access to the Service, or delete your account, if:

• you materially or repeatedly breach these Terms or applicable law;
• your use of the Service creates risk or harm to us, other users, or any third party;
• we are required to do so by law or by a regulatory authority; or
• your account has been inactive for an extended period and you do not have an active paid subscription.

Where reasonable, we will give you notice before suspension or termination.

15.3 Effect of termination. On termination:

• your licence to use the Service will cease;
• we may delete or deactivate your account;
• certain data may be retained as required or permitted by law and as described in our Privacy Policy.

Termination does not limit any rights or remedies that we may have under these Terms or under applicable law.

20. General Terms

20.1 Entire agreement. These Terms, together with the Privacy Policy and any additional terms we present for specific features, constitute the entire agreement between you and Zeno regarding the Service and supersede any prior or contemporaneous agreements.

20.2 Severability. If any provision of these Terms is found invalid or unenforceable, the remaining provisions will remain in full force and effect.

20.3 No waiver. Our failure to enforce any right or provision under these Terms does not constitute a waiver of that right or provision.
