Privacy Policy

EULJI · Effective August 31, 2026 · Name updated September 8, 2026

The EULJI team (the “Team”) provides the EULJI mobile app and processes your personal information and health-related records as described below.

1. Information we process

Account information: Firebase user identifier, email address and display name.
Profile and health records: goals, body measurements, health notes, and meal, workout, weight and body composition records.
Service content: AI coaching conversations, photos and attachments you upload, saved content, commitments and reports.
Environment information: language, time zone, app version, and device and push notification tokens.
Subscription information: product, hashed transaction identifiers, subscription status and expiration time. Apple or Google processes the original payment method information.
Operational information: error, performance and security logs, and App Check verification information.

2. How we use information

To authenticate users, connect records to one member profile and protect accounts.
To store health records, generate statistics and reports, and provide personalized AI coaching.
To verify subscription purchases, restore purchases, and reflect refunds, cancellations and expiration.
To deliver push notifications, provide support, analyze errors and secure the service.

3. Systems and external providers

To provide the service, the Team uses Google Firebase for authentication, App Check, databases, storage, server functions, notifications, and error and performance analysis; the EULJI coaching server and database; AI model providers; and the Apple App Store and Google Play payment systems. These providers may process information as necessary to perform their respective functions. The Team does not sell personal information.

4. Retention and deletion

Information is retained for as long as needed to maintain your account and provide the service. When you request account deletion from Profile in the app, we delete your authentication account and personal content in the member records managed by the Team. However, we may retain the minimum information required for fraud prevention, disputes, accounting, e-commerce or other applicable legal obligations separately for the required period before deleting it. Apple and Google may retain purchase history separately under their store policies.

5. Your rights and account deletion

You can view and correct your profile and records in the app and request deletion under Profile → Delete account. Account deletion does not cancel an auto-renewing App Store or Google Play subscription. Cancel your subscription separately in the relevant store settings. If you cannot access the app, use the contact details below to request access, correction or deletion.

6. Security measures

The Team applies encryption in transit, per-user access controls, server-side token and app authenticity verification, protection against payment transaction reuse, limited administrator privileges and security log review. Authentication tokens, payment tokens and administrator secret keys are not embedded in the app binary.

7. Children's privacy

The service is not directed at children under 14. If we become aware that a child's information was collected without the consent of their legal guardian, we will verify the circumstances and delete the information.

8. Changes and contact

Material changes will be announced in the app or on a public page before taking effect. For privacy questions or to exercise your rights, contact eulji_support@naver.com.
