Privacy policy
Korea Through Photographs (the Service), operated by 커피한잔, explains the sources and categories of personal information, purposes, public visibility, retention periods and how to exercise your rights under the Korean Personal Information Protection Act.
Effective date:
Your first Kakao login automatically creates an account. Current account features cover login and account management. Comments, replies and photo editing are not available yet.
1. Information and purposes
We provide registration and login through Kakao. We save only the information listed below that you agree to share through Kakao. New accounts are regular users; the operator assigns moderator access separately.
Kakao user ID, nickname, profile photo URL, email, gender, age range and birth year are required information for registration. There are no optional collection items. We identify accounts by their Kakao user ID and do not guess or fabricate information that Kakao does not provide.
| Information | Collection condition | Purpose | Visibility | Retention |
|---|---|---|---|---|
| Kakao user ID | Required | Registration, login, identifying the same member and account management. | Private | Until account deletion or withdrawal of consent |
| Nickname | Required | Building your account profile and identifying your own signed-in account. | Shown in your account menu | Until account deletion or withdrawal of consent |
| Profile photo URL | Required | Storing the Kakao profile photo address as account profile information. | Private | Until account deletion or withdrawal of consent |
| Required | Managing the contact address provided by Kakao. Matching email addresses do not cause accounts to be merged. | Private | Until account deletion or withdrawal of consent | |
| Gender | Required | Recording your gender during registration and using it for private member profile and account management. | Private | Until account deletion or withdrawal of consent |
| Age range | Required | Recording your age range during registration and using it for private member profile and account management. | Private | Until account deletion or withdrawal of consent |
| Birth year | Required | Recording your birth year during registration and using it for private member profile and account management. | Private | Until account deletion or withdrawal of consent |
The Kakao user ID is necessary to identify your account. We collect nickname, profile photo URL, email, gender, age range and birth year with mandatory consent during registration.
We do not collect your name (legal name), CI, birthday (month and day), phone number or shipping information through Kakao registration or login. A nickname is a separate field from your name (legal name). We request and store only the information listed in the table from the Kakao API, and never collect your Kakao password or resident registration number.
We store the profile photo URL without copying the image file. Kakao access tokens, refresh tokens and full API responses are not saved in member tables.
For email inquiries and photo submissions, we use the email address, name or nickname, message and attachments you provide to handle and respond to your request, retaining them until that purpose is fulfilled.
Server logs may record IP addresses, access times, request paths and errors for operation and troubleshooting. Authorization codes, tokens and member profiles are filtered from logs.
2. Consent and the right to refuse
Review the information requested on Kakao's consent screen before agreeing and logging in. A successful first login creates your account. Visiting this page or reading the policy does not constitute consent.
Consent to collect and use nickname, profile photo URL, email, gender, age range and birth year is required for registration. If you refuse this consent, you cannot complete registration.
You may refuse consent or cancel login. Public photos remain available without an account. Registration is not completed if Kakao authentication cannot be completed.
Changes to collection scope or purposes will be explained before they take effect, with any necessary consent procedures.
3. Visibility of member information
Member information is not currently made public to other visitors. Your nickname appears in your own account menu. Kakao user ID, email, gender, age range, birth year and profile photo URL are not displayed on public pages.
We will explain the scope of disclosure before introducing comments, replies or public profiles.
4. Retention and deletion
Kakao user ID, collected profile information, registration time and latest login time are retained until account deletion or withdrawal of consent, then deleted without undue delay. Information no longer needed is also deleted when its purpose has been fulfilled.
Login persistence tokens keep you signed in and are invalidated at logout. Login persistence lasts three months and may be extended when you return.
Inquiry materials and operational logs are deleted when their purposes have been fulfilled. Information subject to a legal retention obligation is kept separately for the applicable period.
Electronic files selected for disposal are deleted in a way that prevents recovery; any paper records are shredded or incinerated.
5. Sharing and service providers
We do not sell or arbitrarily disclose member information. Any disclosure based on separate consent or a legal basis is limited to that scope.
Kakao provides login information with your consent. Kakao's own privacy policy governs your Kakao account.
We use Google Analytics through Google Tag Manager on the production service to analyze visits and usage and improve the service. Pages visited, access times, browser and device information, and cookie identifiers may be sent to Google. Any necessary notices and consent procedures for processing outsourcing or international transfers will be disclosed in this policy.
7. Your rights
You may request account deletion, withdrawal of consent, access, correction, erasure or suspension of processing through the email below. We verify your identity or your representative's authority before handling the request.
Changing your Kakao profile does not automatically update every profile field in this service. Contact us to correct information or check the status of Kakao unlinking and account deletion.
We use only the minimum information needed to verify requests and do not ask for your Kakao password or resident registration number.
8. Security measures
Access to personal information is limited to operators who need it. Authentication settings are managed securely. Production login uses HTTPS, and authentication tokens and personal information are filtered from logs.
Account permissions are managed on the server, and login requests are checked for forgery. We avoid unnecessary storage of profile response data and authentication tokens.
