GlucoUs Inc. (hereinafter the "Company") establishes and discloses this Privacy Policy in accordance with the Personal Information Protection Act, the Act on Promotion of Information and Communications Network Utilization and Information Protection, and other relevant laws, to protect users' personal information and to promptly and smoothly handle related grievances.

Article 1 (Purposes of Processing Personal Information)

The Company processes personal information for the following purposes. Personal information is not used for any purpose other than those stated below, and if the purpose of use changes, the Company will take necessary measures such as obtaining separate consent.

  1. Membership registration and management — maintaining membership status, preventing fraudulent use, delivering notices
  2. Service provision — meal logging, providing carbohydrate estimates, meal history lookup, and other app features
  3. Service improvement and statistical analysis — understanding usage, diagnosing app errors, developing new features
  4. Marketing and information — event and new service announcements (only where separate consent is obtained)

Article 2 (Personal Information Items Processed)

General Items Collected

  • Account: Email address, social login identifier (Google/Apple ID) — required, at registration
  • Service Usage: Food photo images, food selection history, portion adjustment inputs, meal history — required, during Service use
  • Device: Device identifier, OS type/version, app version, language settings — automatically collected
  • Service Logs: Access timestamps, feature usage records, error logs — automatically collected
  • Newsletter (including non-members): Email address, time of consent — optional, when you sign up for news (only where consent to receive email has been given)

Food photo images may contain information from which a user's dietary habits and health condition could be inferred. The Company does not use this information beyond the purposes stated in Article 1.

Sensitive Information (collected only with separate explicit consent)

The following items constitute sensitive information (health information) under Article 23 of the Personal Information Protection Act. The Company obtains explicit consent separate from general personal information consent before collection; declining does not restrict access to the Service's core features.

  • Diabetes type (Type 1/Type 2/gestational, etc.) — from Phase 1.5 onward, if entered directly by the user, optional
  • CGM blood glucose data — from Phase 1.5 onward, if a CGM device is connected, optional

The above sensitive information is not collected during the initial Phase 1 launch.

Optional Consent Items (Research Participation)

The Company may pseudonymize users' meal record and nutrition data and use it as follows. Each purpose can be individually opted into, and declining does not result in any disadvantage in using the Service.

Category Purpose of Use Retention Period Consent Type
Scientific research
(no consent required, Art. 28-2)
Improving AI recognition and nutrient estimation algorithms through analysis of correlations between meal images and nutrition data Until purpose is achieved No legal consent required

When pseudonymized data is used for academic research, the Company proceeds only after the relevant research undergoes IRB (Institutional Review Board) ethical review. To ensure the safety of pseudonymized information, the Company implements managerial (internal management plan, regular training), technical (separate storage of additional information, restricted access, retention of processing records), and physical (access control to server rooms and data storage areas) safeguards.
