Terms of Service

Effective date: 14 Sep 2026

These terms govern your use of the Ayuvo apps for iPhone, Apple Watch and Android ("the app"), published by Yaara Tech, Karauli, Rajasthan, India ("we", "us"). By installing or using the app you agree to them. If you do not agree, do not use the app.

1. The service

Ayuvo is a personal health companion that runs on your device: it logs meals, workouts, fasting and water, mirrors the Apple Health / Health Connect data you grant into a local hub, and offers an AI coach that works with the AI provider key you supply. The app has no account and no Ayuvo-operated server; how your data is handled is described in the Privacy Policy, which forms part of these terms.

2. Licence to use the app

We grant you a personal, non-exclusive, non-transferable licence to install and use the app on devices you own or control, as distributed through the Apple App Store and Google Play. The app is built on an MIT-licensed open-source code base; the MIT notice is reproduced in the app under Settings → Legal → Licenses and in section 12 below. The Ayuvo name and mark are not covered by that licence and may not be used without our permission.

3. Bring-your-own-key responsibility

  • AI and speech features work with API keys you obtain from a provider of your choice. You are responsible for obtaining, securing and paying for those keys and for complying with the provider's terms.
  • Keys are stored only on your device and are never transmitted to us. Usage, rate limits and billing are between you and the provider.
  • Requests you make (meal photos, text, audio, coach messages and the context the coach retrieves) are sent directly to the provider you configured; its terms and privacy policy apply to that processing.

4. No medical advice

Everything the app shows — AI nutrition estimates, calorie and macro targets, BMR/TDEE calculations, weight forecasts, calculated workout burn, Health data charts and coach replies — is informational and can be wrong. The app is not a medical device and does not diagnose, treat or prevent any condition. Do not use it for emergencies or for decisions about medication, and talk to a qualified clinician before changing your diet, training or fasting, especially if you are pregnant, have a medical condition or are under 18.

5. Acceptable use

Use the app lawfully and only for personal, non-commercial purposes. Do not attempt to bypass the stores' distribution mechanisms, abuse third-party services through the app, or use it in a way that violates a provider's terms.

6. Third-party services

The app relies on services we do not control and whose availability we do not guarantee: your AI and speech providers; Open Food Facts (product data under the Open Database License); the open exercises-dataset repository on GitHub and its exercise media (© Gym visual, used under its attribution terms); Hugging Face for optional on-device model downloads (models under their respective open licences); Apple and Google platform services including Apple Health, Health Connect, iCloud, Google Drive, the App Store and Google Play. Each is governed by its own terms.

7. Health integrations

Enabling Apple Health or Health Connect authorises the app to read and write the data types described in the Privacy Policy. You can revoke access at any time in the Health app or Health Connect settings. Values shown in the app depend on the accuracy of the source apps and devices that wrote them.

8. Your data, exports and backups

Your data lives on your device. You are responsible for exports and for any cloud backup you choose to enable (your own iCloud or Google Drive). Delete All Data removes the app's local storage on the device and cannot be undone.

9. Disclaimer of warranties

The app is provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the app will be uninterrupted or error-free, or that AI estimates will be correct.

10. Limitation of liability

To the maximum extent permitted by the laws of GOVERNING_LAW, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, health outcomes, provider charges or lost profits arising from your use of the app. Our total liability for any claim relating to the app is limited to the greater of the amount you paid us for the app (nil) and INR 1,000. Nothing in these terms limits liability that cannot be limited under applicable consumer law.

11. Governing law and disputes

These terms are governed by the laws of GOVERNING_LAW, and the courts there have exclusive jurisdiction, without prejudice to mandatory consumer-protection rights in your country of residence. Please contact us first at yaaratech@gmail.com; most issues can be resolved informally.

12. Termination, changes and licence notice

You may stop using the app at any time by deleting it. We may update these terms as the app evolves; the effective date above changes with every revision and continued use after a change means you accept it. If any provision is unenforceable, the rest remains in effect.
