Privacy policy
How Entity Flow processes data for Entity Clinic Kakao login, self-checks and enquiries.
Published and effective: 2026.09.28
Scope and operator
The operator is Entity Flow, represented by Siheon Kim. This policy covers the public entityclinic.com website and Kakao login. The private content workspace at studio.entityclinic.com uses separate sign-in and privacy notices. Kakao login alone does not grant workspace access or start a paid subscription.
Kakao login: data, purpose and retention
We use the app-specific user ID issued by Kakao, authentication tokens, session issue and expiry times, and authentication request verification values to verify and maintain login. The user ID is an app identifier, not a resident registration number. These items are necessary for login. The current implementation does not retrieve names, nicknames, profile pictures, email addresses, phone numbers, dates of birth or friend lists. This website never receives your Kakao password.
Login storage and expiry
We do not create a separate member database. The login user ID and access token are kept in an encrypted secure cookie for up to one hour, or less if the token expires sooner. The authentication request cookie lasts up to ten minutes. The server temporarily processes this information during authentication. These periods concern login cookies and do not describe infrastructure access-log retention.
Access approval information
Only operator-approved accounts may access My Services after Kakao authentication. An approval request code is derived from the verified user ID; approved codes are kept in server-side access settings to check permissions and prevent unauthorized access. They are retained while access is authorized and removed when the operator revokes permission or fulfills a deletion request, independently of the one-hour login cookie. The code alone cannot log you in or grant access.
Basis for processing and your choice
The minimum information necessary to authenticate is processed to provide the login service you request, under Article 15(1)(4) of the Korean Personal Information Protection Act. You can review disclosure items on Kakao’s consent screen or cancel login. Public pages and self-checks remain available without login; the My Services page does not. Reading this policy does not constitute consent to advertising messages or additional data collection.
Logout, unlinking and deletion
Logout removes the login cookie and requests token logout from Kakao. Unlinking disconnects this service from your Kakao account and removes the login cookie after success. Expired sessions cannot be reused. You can also delete site data through your browser settings. Deleting browser cookies alone does not disconnect Kakao or delete enquiry records separately submitted.
Self-checks and storage on your device
Clinic names, website addresses, answers and notes entered in the self-check are processed only in browser memory, not sent to our server or an external AI service. Copy uses your device clipboard; download saves a file to your device. Refreshing or closing the page resets the site’s input state, while browser restoration, downloaded files and the clipboard remain under your control. Do not enter patient identifiers, medical records or health information.
External services and hosting
Kakao handles authentication, token validation, logout and unlinking. The website runs on OpenAI Sites and Cloudflare infrastructure. IP addresses, request URLs, access times, browser information and authentication requests may be processed for delivery, execution and security. Processing on overseas infrastructure is possible. Providers’ general policies alone do not establish every processing country or access-log retention period applicable to this site. You may ask our privacy contact for clarification.

Service and privacy enquiries
The Kakao chat link opens Kakao. Login information and self-check notes are not automatically sent as chat messages. If you send a message, the operator can see your displayed profile and message content. Chat records are processed separately from login cookies; the one-hour cookie lifetime does not apply to chat records. You may request access to or deletion of chat records through the contact below. Do not send passwords, verification codes or patient information.
Your rights and how to exercise them
You or an authorized representative may request access, correction, deletion, restriction of processing or withdrawal of consent. Use logout or unlinking in My Services, or contact us below. We verify identity or authority to the extent necessary and explain the result in accordance with applicable law. If a legal restriction prevents fulfillment, we explain the reason. Kakao account information itself can also be managed through Kakao.
