Service Improvement Data Consent

Effective Date: July 15, 2026

This consent is optional. Refusing it does not restrict your access to the core Service.

Note: Basic operational analytics (such as core error logging and Google Analytics) are processed as service delivery items under our main Privacy Policy. Advanced behavioral session tracking (Microsoft Clarity) is governed strictly by your separate, explicit choice in the optional Consent for Behavioral Tracking and Analytics. This current consent is strictly limited to linking your permitted tracking logs with demographic metrics for user-preference segmentation.

1. Purpose of Consent

Analyzing user preferences and application usage patterns by demographic segment to optimize our user interface, improve feature layouts, and personalize product experiences.

2. Items Used and Linked

With your explicit consent, we will securely link:

• Demographic Profile Information: Gender, birth year (or age bracket), and interface language.

• Behavioral Event Alignment: Permitted application interaction logs (screen views, taps, navigation paths) connected to an internal, pseudonymous user identifier.

Exclusions: Chat history, AI chatbot queries, and fortune exam data are strictly excluded from this consent. They are governed separately by the “AI Training Data Consent.”

3. Retention and Use Period

The demographic-linked analytical data will be retained and used for a maximum period of two (2) years from the date of collection, or until you withdraw your consent, whichever occurs first. Upon expiration or withdrawal, the linked raw data points will be permanently deleted or completely anonymized into non-identifiable, aggregated statistics.

4. Right to Refuse and Effect of Refusal

This consent is optional, and you may refuse it at any time. Refusal will only limit demographic-segment personalization. Core services—including account creation, Saju interpretation, AI chatbots, and fortune exams—remain fully available without restriction.

5. How to Withdraw

You may easily withdraw consent at any time via either of the following methods:

• In-App Toggle: Navigate to Settings > Privacy & Terms > Service Improvement Data Consent and toggle it OFF.

• Email Request: Contact our compliance team directly at [dev@bangguseok.co.kr].
