Zenda Terms of Service
Version 1.0 — Effective 2 July 2026
These Terms are an agreement between you and Zenda, operated by Tauro Labs, contact hello@useambr.com ("Zenda", "we"). By creating an account or using the app you agree to them. If you do not agree, do not use Zenda.
1. What Zenda is — and is not
Zenda is an AI-assisted fitness and nutrition coaching app. It builds training and meal plans, tracks your progress, and gives you feedback based on the information you provide and, with your permission, your Apple Health data.
Zenda is not a medical service. It does not provide medical advice, diagnosis, or treatment, and it is not a medical device. Nothing in the app — including AI-generated plans, reports, notes, and estimates — is a substitute for advice from a qualified healthcare professional. See section 5 and the Health Disclaimer, which is part of these Terms.
2. Eligibility
You must be at least 16 years old to use Zenda. By using Zenda you confirm that you are 16 or older and legally able to enter into this agreement.
3. Your account
- Keep your credentials secure; you are responsible for activity on your account.
- Provide accurate information — the coaching is only as good as what you tell it, and materially false safety information (for example about injuries or medical conditions) can make the plans unsuitable for you.
- One account per person; accounts are personal and non-transferable.
- You can delete your account at any time in Settings. Deletion is immediate and permanent (see the Privacy Policy).
4. AI-generated content
Zenda's plans, reports, coach notes, and nutrition estimates are generated by an AI model. You acknowledge that:
- AI output can be inaccurate, incomplete, or unsuitable for your specific circumstances, even when it sounds confident.
- Calorie and macronutrient figures are estimates, not measurements.
- The AI does not know anything you have not told it or granted it access to.
- You remain responsible for the decisions you make — particularly regarding allergies, intolerances, medical conditions, and injuries. Always check food labels and your own tolerances; never rely on an AI estimate for allergen safety.
5. Health and safety
Physical exercise and dietary change carry inherent risks, including injury and, in rare cases, serious harm. By using Zenda you agree that:
- You should consult a physician before starting this or any exercise or nutrition programme — especially if you are pregnant, have (or suspect) any medical condition, are recovering from injury, or take medication.
- You will stop exercising and seek medical attention if you feel pain, dizziness, shortness of breath, or anything else abnormal.
- You use the plans and suggestions at your own risk and within your own limits.
- Zenda is not intended for the treatment of eating disorders or any other condition. If tracking food or weight harms your wellbeing, stop using the app and seek professional support.
6. Your content and licence
You retain all rights to the content you provide (photos, comments, logged data). You grant us a limited, revocable, non-exclusive licence to store and process that content solely to operate Zenda for you — including sending relevant parts to our AI processor to generate your coaching content, as described in the Privacy Policy. We claim no other rights; we do not use your content for advertising and we do not sell it. The licence ends when the content or your account is deleted.
7. Acceptable use
You agree not to:
- use Zenda for anyone other than yourself, or on behalf of a minor under 16;
- probe, overload, disrupt, or reverse-engineer the service or its AI prompts;
- attempt to access another user's data;
- use the service to generate content for resale;
- upload unlawful content or content that is not a photo of yourself to the progress-photo feature.
We may suspend or terminate accounts that violate these Terms.
8. Intellectual property
The app, its design, branding, exercise catalogue, and software are ours or our licensors' and are protected by law. These Terms give you a personal, non-transferable, non-exclusive licence to use the app on Apple devices you own or control, as permitted by the App Store terms. Your personal coaching content is yours to keep and export.
9. Price
Zenda is currently free of charge. We may introduce paid features in the future; if we do, pricing and terms will be presented clearly before you pay anything, and continued use of existing features will not be silently converted into a paid obligation.
10. Availability and changes
We work to keep Zenda available and improving, but we do not guarantee uninterrupted service, and features may change. AI processing depends on third-party providers; outages can delay plans and reports. We may modify these Terms; material changes will be shown in the app and require your renewed acceptance before continued use.
11. Disclaimers and liability
To the maximum extent permitted by law:
- Zenda is provided "as is" without warranties of any kind, express or implied, including fitness for a particular purpose.
- We are not liable for indirect or consequential damages, or for injury or health outcomes resulting from your exercise or dietary choices, except where caused by our wilful misconduct or gross negligence.
- Nothing in these Terms limits liability that cannot be limited by law, or your statutory rights as a consumer — including those under EU consumer law, which remain unaffected.
12. Apple App Store terms
These Terms are between you and Zenda, not Apple. Apple has no obligation to provide support or maintenance for the app and is not responsible for it, for these Terms, or for any claims relating to the app (including product liability, regulatory compliance, and IP claims). Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. You confirm you are not in a country under a U.S. government embargo and are not on any U.S. restricted parties list.
13. Governing law and disputes
These Terms are governed by the laws of Ireland. If you are a consumer in the EU/EEA, you also enjoy the mandatory consumer protections of the country where you live, and you may bring proceedings in your local courts. Before any dispute, we would genuinely rather you just email us — most problems can be fixed quickly.
