These Terms of Use (“Terms”) govern your access to and use of the Luko mobile application and related services (the “Service”). By downloading, accessing, or using Luko, you agree to these Terms and our Privacy Policy.

1. Eligibility

You must be at least 13 (or the age of digital consent in your country). If under 18, a parent/guardian must agree. Personal, non-commercial use only.

2. The Service (current scope)

Luko currently provides:

Not included in this version: workout/fitness tracking, a context/condition journal, AI chat or voice coaching, or in-app purchases / subscriptions. Features may change; material changes will be reflected in updated Terms.

3. Health disclaimer

LUKO IS NOT A MEDICAL DEVICE AND DOES NOT PROVIDE MEDICAL ADVICE.

Nutrition estimates, calorie targets, and related content are for general informational and personal tracking only. They may be incomplete or wrong. Consult a qualified healthcare professional before changing diet or if you have health concerns. For emergencies, contact emergency services.

4. Accounts

You may need an account (Clerk / supported providers). Provide accurate information, keep credentials confidential, and be responsible for activity under your account. We may suspend or terminate accounts that violate these Terms. Delete your account in Settings → Accounts or by contacting support.

5. License & acceptable use

We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the app on Apple devices you own or control, as allowed by the App Store Terms of Use.

You agree not to reverse engineer or misuse the Service; upload unlawful or infringing content; access others’ accounts or our systems without authorization; use the Service to diagnose or treat disease; or overload or abuse AI/analysis systems.

6. Your content

You retain ownership of content you submit. You grant us a worldwide, non-exclusive license to host, process, analyze, and display that content as needed to operate and improve the Service (including AI meal analysis). You represent you have the rights to submit that content.

7. AI meal analysis

AI outputs are estimates. We do not guarantee accuracy of calorie/macro estimates or food identification. Do not use them as a substitute for professional advice.

8. No purchases in this version

This version of the App is free and does not offer in-app purchases or auto-renewable subscriptions. If we add paid features later, prices and terms will be shown in the App and on the App Store, and these Terms will be updated.

9. Intellectual property

Luko branding, character, UI, and software are owned by us or our licensors. These Terms do not transfer ownership to you.

10. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. We do not warrant uninterrupted service or accurate nutrition estimates.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR LOSS OF DATA, PROFITS, OR HEALTH OUTCOMES, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM WILL NOT EXCEED USD $50. Some jurisdictions disallow certain limits; then limits apply to the fullest extent allowed.

12. Termination

You may stop using the Service anytime and delete your account. We may suspend or terminate access for violation of these Terms or risk to users/systems. Disclaimers, liability limits, and IP terms survive termination.

13. Changes

We may update these Terms. Material changes will be posted with a new effective date. If you do not agree, stop using the Service and delete your account.

14. Governing law

These Terms are governed by the laws of the State of California, excluding conflict-of-law rules. Courts located in San Francisco County, California have exclusive jurisdiction, except where consumer protection law or Apple’s App Store terms require otherwise.

15. Apple-specific terms

These Terms are between you and Zentari Labs Inc., not Apple. Apple has no obligation to provide maintenance or support for Luko. Apple is not responsible for product warranties beyond any applicable refund of an app purchase price; nor for product liability, consumer, or IP claims related to the app. Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms.
