Zentra is a personal wellness diary that helps you record your nutrition, hydration, movement, weight, mood, digestion, cycle, wellbeing and medication routines (including GLP-1 medication), and offers AI-generated reflections about your own daily patterns. Zentra is intended to support personal reflection and wellness tracking only. It is not a medical device, a diagnostic tool, or a healthcare service. By creating an account or using Zentra, you agree to these Terms & Conditions and acknowledge our Privacy Policy.
Zentra does not provide medical advice, diagnosis or treatment, and nothing in the app — including your logged data, charts, summaries and AI insights — should be used as the sole basis for healthcare, dietary, exercise or treatment decisions. The information you see in Zentra is a record of what you have entered and general informational commentary about it; it is not a substitute for advice from a qualified healthcare professional who knows your personal circumstances. Always consult a healthcare professional before making decisions about your health, medication, diet or exercise. Never start, stop, change or delay any medication (including GLP-1 medication) based on anything you see in the app.
Where Zentra uses AI to help you log — for example when estimating calories, protein, carbohydrates or fat — these figures are approximations only and should be treated as such.
Some features of Zentra use artificial intelligence to analyse the information you provide and generate personalised reflections and insights. AI-generated content may contain errors, omissions or inaccuracies, may miss relevant context, and may not always be relevant to your individual circumstances. AI insights are provided for general wellness and informational purposes only, are not reviewed or approved by a healthcare professional, and do not establish or confirm any medical condition, cause or connection.
Importantly, the AI does not know what is medically happening in your body. When it describes a possible pattern between, for example, something you ate and how you felt, it is only reflecting what you logged — a suggestion for your own reflection, not a proven medical link or a diagnosis. You remain responsible for how you interpret and act on any AI-generated content.
You are responsible for the information you choose to record in Zentra, for keeping it accurate where it matters to you, and for how you use the information and insights the app provides. Zentra is intended to support personal reflection and wellness tracking and should not be used as the sole basis for healthcare or treatment decisions. Any decision you make based on your data, charts, summaries or insights — whether the data came from your own logging or from AI-generated content — is your own responsibility, and Zentra is not responsible for actions taken or not taken as a result of information in the app.
Zentra is not designed for emergencies or urgent health situations. Do not rely on Zentra for emergency assistance, diagnosis or urgent medical decisions. If you believe you may have a medical emergency, contact your local emergency services or seek immediate medical attention.
We take the privacy and security of your personal information seriously, and we recognise that what you log in Zentra can include sensitive health and wellbeing information. Your information is used to provide, personalise and improve the Zentra experience and to operate the services you request. We do not sell your personal information, and we do not use it for advertising.
Our collection, use, storage, protection, sharing and deletion of personal information — including health-related information, AI processing, and your available choices — is described in our Privacy Policy. By using Zentra, you acknowledge that you have read and understood the Privacy Policy.
Zentra reflects what you enter, so the value of your history and insights depends on the accuracy and completeness of your entries. Nutrition estimates, cycle predictions and other derived figures are approximations and may be incomplete or inaccurate. We are not responsible for conclusions drawn from inaccurate, incomplete or out-of-date entries, or for data loss caused by incorrect entries you make or edits you apply.
You agree to use Zentra lawfully and only for its intended purpose — tracking your own wellbeing. You may not misuse the app, attempt to gain unauthorised access to other people's data, upload unlawful or offensive content, interfere with the service, or use the app to harm yourself or others. We may suspend or end accounts used in breach of these terms.
You are responsible for keeping your account credentials secure and for all activity that happens under your account. If you believe your account has been accessed without your permission, please contact us promptly through the contact option in the app. We are not responsible for losses arising from unauthorised access caused by a failure to keep your credentials secure.
Zentra relies on third-party services to operate, including hosting and account sign-in, secure storage, AI functionality for insights and nutrition estimates, email delivery, and basic usage analytics. These services may process information as necessary to provide their services. Further information is provided in our Privacy Policy.
We aim to keep Zentra available and functioning reliably, but we do not guarantee that the service will always be available, uninterrupted or error-free. Features may occasionally be changed, updated, suspended or discontinued. We are not liable for entries you are unable to record, or data you cannot access, while the service is temporarily unavailable.
We may update Zentra, introduce new features or modify existing functionality from time to time — for example as tracking tools and insights evolve. Where appropriate, we'll let you know about significant changes within the app.
All rights in Zentra, including its software, design, branding, logos, text and original content, are owned by or licensed to Zentra and may not be copied, reproduced, modified or redistributed without permission. The entries, notes and photos you log remain yours; you keep all rights to your content, and you are responsible for making sure you have the right to upload anything you share in the app.
You can review, edit or delete any individual entry at any time from within the app. Details about deleting your account and associated personal data, and how your information is handled on deletion, are described in our Privacy Policy. If you have questions about your data, use the contact option in the app.
Zentra is intended for users aged 18 and over. By creating an account, you confirm that you meet this age requirement.
To the fullest extent permitted by law, Zentra is provided "as is" without warranties of any kind, and we are not liable for any loss or harm arising from your use of the app, reliance on its data, summaries or insights, service interruptions, or health decisions you make based on information recorded or generated in the app. Nothing in these terms limits liability that cannot be limited by law.
We may update these terms from time to time — for example when features, services or laws change. If we make significant changes, we'll let you know within the app; continuing to use Zentra after that means you accept the updated terms.
