This Privacy Policy explains how we collect, use, share, and protect information when you use the Luko iOS app and related services (the “Service”).

1. Who we are

Luko is a consumer wellness app focused on food logging and personal nutrition targets. You can complete onboarding, set a calorie/macro plan, log meals (photo, text, or voice description), unlock Adventure companions as you log, and manage your profile in Settings.

Luko is not a medical device and does not provide medical advice, diagnosis, or treatment.

This version does not include workout/fitness tracking, a daily context/condition journal, AI chat coaching, or paid subscriptions. If we add those later, we will update this Policy.

2. Information we collect

A. Account & identity

When you create or sign in (via Clerk and supported sign-in methods), we may collect name, email address, authentication identifiers/tokens, and account settings (e.g., timezone).

B. Profile & wellness information you provide

During onboarding and in settings, you may provide age/birthday, sex or gender, height, weight, goals (lose/maintain/gain), activity level, pace, dietary preferences, allergies, and disliked foods. This may be treated as health-related personal data under some laws. We use it to personalize calorie/macro targets.

C. Food-logging content

Meal photos (camera or photo library), typed or voice meal descriptions, structured meal logs, estimated calories/macros, and meal history.

D. Adventure progress

Companion unlock progress, map progress, and related Adventure state may be stored on your device (and, if we sync it later, on our servers) so you can keep Stars / Companions as you log meals.

E. Device & technical data

Device type, OS/app version, diagnostics needed to operate and secure the Service, push notification tokens (if enabled), and local preferences on device.

F. Permissions (iOS)

Permission Purpose
Camera Scan meals
Photo Library Choose meal photos
Microphone Voice meal descriptions (if used)
Notifications Optional habit reminders
Motion Optional: make Meal tokens tumble when you tilt or shake your phone

You can change permissions in iOS Settings.

G. Children

We do not knowingly collect personal information from children under 13 (or the minimum age required in your country). Contact us to request deletion if needed.

3. How we use information

We use information to provide the Service (account, plan targets, meal logging, Adventure progress, history, settings); analyze meals with AI to estimate nutrition; authenticate and secure accounts; send optional push reminders you opt into; improve reliability and safety; and comply with law / enforce our Terms.

We do not sell your personal information. This version does not process payments or subscription data.

4. AI processing (meal analysis)

When you log food by photo, text, or voice, relevant content may be sent to our servers and/or subprocessors so we can return nutrition estimates. Outputs are estimates and may be inaccurate. Do not rely on them for medical decisions.

5. How we share information

We may share information with service providers (hosting, Clerk, AI providers, support) under contracts that limit use to serving us; Apple for sign-in and App Store operations; and legal/safety recipients when required by law or to protect rights, or in a merger/acquisition (with notice where required).

We do not share meal photos or health profile data for third-party advertising.

6. Retention

We keep information while your account is active and as needed to provide the Service, resolve disputes, and meet legal obligations. Delete your account in-app (Settings → Accounts) or by emailing us; we will delete or anonymize personal data except where law requires retention.

7. Security

We use reasonable administrative, technical, and organizational measures (including encrypted transit and access controls). No method of transmission or storage is 100% secure.

8. Your choices & rights

Depending on your location, you may have rights to access, correct, delete, export, restrict, or object to certain processing, and to withdraw consent.

Requests: hu@zentarilabsinc.com

Account deletion: Settings → Accounts, or email us from your account email.

You can also turn off notifications, revoke camera/photos/microphone /motion access in iOS Settings, and sign out.

9. International transfers

We may process data in the United States and other countries where we or our providers operate. Where required, we use appropriate transfer safeguards.

10. Changes

We may update this Policy when features or data practices change. We will post a new effective date. Continued use after changes means you accept the updated Policy where permitted by law.
