1. Information we process, purposes, and retention
The Operator processes only the minimum information needed to provide the Service and uses it only for the purposes below. If a purpose changes, the Operator will take the steps required by Article 18 of PIPA.
| Category | Items | Purpose | Legal basis | Retention |
|---|---|---|---|---|
| Connection data used to deliver web pages (processed by the hosting servers) |
IP address, access time, requested page address, browser and device information (User-Agent), referrer | Delivering web pages; blocking abnormal access and security threats | PIPA Article 15(1)(6) (the Operator’s legitimate interests) | Not retained (discarded as soon as the request is handled). The Operator does not use access-log storage. |
| Visit statistics (Google Analytics) |
Cookie (a random identifier that tells visitors apart), page address and title, referrer, visit time and duration, screen changes and button use, browser, device, and OS information, screen size, language, approximate location (country and city) estimated from your IP address | Improving the Service through statistics such as visitor counts and usage flow | PIPA Article 15(1)(6) (the Operator’s legitimate interests); see Section 7 | Automatically deleted 2 months after collection (Google Analytics data retention setting) |
| Advertising data (collected directly by Google) |
Cookies and advertising identifiers, IP address, page address, browser and device information, ad impressions and clicks | Serving ads and personalized ads, measuring ad performance, preventing invalid clicks | See Sections 7 and 8 | According to Google’s policies (Section 8) |
The Operator does not offer sign-up, log-in, or contact forms. If you contact the Operator by email, your email address and message are processed to reply and are deleted within one year after the inquiry is resolved.
In Google Analytics, your IP address is used only to estimate an approximate location and is not logged or stored. The Operator does not use Google Analytics to identify individual users, does not use Google signals (ad-linking features), and does not share statistics for advertising.
2. What you enter (birth dates, etc.)
To check compatibility, you enter the following for yourself and for the other person:
- Nickname, solar or lunar calendar, leap month, date of birth, time of birth (optional), birthplace region (Korean version only), and the rule for births in the Ja hour (11 PM–1 AM)
This information is used only inside your device’s browser to calculate the Saju charts and draw the compatibility card. It is never sent anywhere, including the Operator’s servers, advertisers, or the visit statistics tool (Google Analytics), and it is not saved in cookies or browser storage. It disappears when you close or reload the page.
When you tap “Save image” or “Share”, a card image with the nicknames and the result is saved to your device or passed to the app you choose. The card does not include birth dates. Shared images are handled under the policies of that app’s operator.
If you enter another person’s birth details, please let them know beforehand where possible. We recommend nicknames instead of real names.
3. Disclosure to third parties
The Operator does not provide users’ personal information to third parties, except where the law specifically requires it or an investigative agency requests it under the procedures set by law.
Information that Google collects directly through the ad code on the Service’s pages is described in Sections 7 and 8. Visit statistics (Google Analytics) fall under the processing described in Section 4.
4. Processors
The Operator entrusts the following processing to run the Service:
| Processor | Task | Retention |
|---|---|---|
| Amazon Web Services, Inc. | Website hosting and content delivery (Amazon S3, Amazon CloudFront) | Discarded as soon as the request is handled (no access logs kept) |
| Google LLC | Visit statistics (Google Analytics) | 2 months after collection, or until the contract ends |
Under Article 26 of PIPA, the Operator’s agreements with processors prohibit processing beyond the entrusted purpose, require security measures, and restrict sub-processing, and the Operator supervises whether processors handle personal information safely. Any change of processor or task will be announced in this policy.
5. Transfers outside Korea
While you use the Service, personal information may be transferred outside the Republic of Korea as follows (PIPA Article 28-8).
| Recipient (contact) | Country | Items | When and how | Purpose | Retention |
|---|---|---|---|---|---|
| Google LLC Privacy inquiries |
United States and other countries with Google data centers | Cookies and advertising identifiers, IP address, page address, browser and device information, ad impressions and clicks | Sent over the network through the ad code when you open a page | Serving ads, personalized ads, performance measurement, fraud prevention | According to Google’s Privacy Policy |
| Google LLC Privacy inquiries |
United States and other countries with Google data centers | Visit statistics (Section 1) | Sent over the network through the analytics code when you open a page or move between screens | Visit statistics | 2 months after collection |
| Amazon Web Services, Inc. Contact AWS |
The origin server is in the Republic of Korea (Seoul region). Pages pass through the CloudFront edge server nearest to you, which may be in another country. | IP address, requested page address, browser and device information | Sent over the network when you open a page | Delivering web pages | Discarded as soon as the request is handled |
Basis for transfer: disclosure in this policy as necessary to conclude and perform the contract with you (use of the Service) (PIPA Article 28-8(1)(3)), and other applicable laws.
If you do not want these transfers, you can block cookies as described in Section 7, or use ad or tracking blockers or the Google Analytics opt-out add-on. The compatibility check still works fully. Connection data is needed to load the pages, so to refuse that transfer you would need to stop using the Service.
6. Deletion
- Procedure: Personal information is deleted without delay once its retention period ends or its purpose is achieved.
- Method: Electronic files are deleted so they cannot be recovered. Visit statistics are deleted automatically when the Google Analytics retention period (2 months) ends. The Operator does not store web server access logs.
- The Operator does not keep what you enter (Section 2), so there is nothing to delete.
7. Cookies and how to refuse them
The Operator does not use cookies or browser storage (such as localStorage) for the compatibility check. However, the following two external codes may store cookies in your browser or read cookies already stored there.
- Google Analytics (visit statistics): stores first-party cookies (
_ga,_ga_*) containing a random identifier that tells visitors apart. They expire after up to 2 years and are used only to count return visits and usage flow. - Google AdSense (ads): uses cookies to serve ads and personalized ads (Section 8).
To opt out of Google Analytics, in addition to the browser cookie settings below, you can install the Google Analytics Opt-out Browser Add-on. To learn how Google uses information collected through Google Analytics, see How Google uses information from sites or apps that use our services.
Cookies are small text files that a website sends to your browser. You can refuse cookies, and the compatibility check will still work normally. Menu names may vary by browser version.

8. Behavioral data and personalized ads
The Service shows ads through Google AdSense. The Operator does not itself collect behavioral data for personalized ads (Google Analytics statistics are not linked to advertising; see Section 1). The Operator allows Google to collect behavioral data through the ad code on the Service as follows.
| Collector | Means | Items | Purpose | Retention |
|---|---|---|---|---|
| Google LLC and Google advertising partners | Ad code (adsbygoogle.js), cookies | Website visits, ad impressions and clicks, IP address, browser and device information | Serving ads tailored to your interests, measuring ad performance | According to Google’s policies |
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
- You may opt out of personalized advertising by visiting Google Ads Settings. You can opt out of third-party vendors’ cookies for personalized advertising at www.aboutads.info/choices.
- Third-party vendors and ad networks other than Google that may serve ads on the Service are listed in Google’s list of ad technology providers. You can opt out of their personalized-ad cookies on each vendor’s website, where offered.
- For how Google uses information from partner sites, see How Google uses information from sites or apps that use our services.
The Operator never passes what you enter for the Saju reading (birth dates, etc.) to the ad code or to Google Analytics, and it is not used for personalized ads. The Operator does not allow the collection of sensitive behavioral data such as health or sex life.
For questions or complaints about behavioral data, contact the privacy officer in Section 12.
9. Children under 14
The Service has no sign-up and does not check or collect users’ ages. The Operator does not serve personalized ads to users it knows to be under 14 and does not allow personalized-ad collection aimed at children. Legal guardians can request action using the contact in Section 12.
10. Your rights
- You may at any time ask the Operator to access, correct, delete, or stop processing your personal information, or withdraw consent (PIPA Articles 35–37).
- You can exercise these rights by emailing the address in Section 12. The Operator will act without delay (within 10 days for access requests) and tell you the result.
- You may also exercise your rights through a legal representative or an authorized person, who must submit a power of attorney.
- Requests may be limited where other laws require the information to be kept, in which case the Operator will tell you why.
- Because the Operator does not keep names, contact details, or other information that identifies you, it may be hard to verify your identity or locate the relevant data for some requests, such as those about visit statistics.
- Google Analytics statistics are stored only under random identifiers that do not identify you, so the Operator may be unable to find, show, or delete a particular user’s data. Instead, you can opt out as described in Section 7.
- You can view and delete advertising data collected by Google yourself in My Ad Center and My Activity.
- If you live outside Korea, you may also have rights under your local law. Email the address in Section 12 and the Operator will respond in good faith.
11. Security measures
- Minimal collection: The Saju calculation is designed to run inside your browser, so what you enter is never sent to a server.
- Encryption in transit: The Service is offered only over HTTPS.
- Access control: Two-step verification is enabled on the hosting and Google Analytics accounts, and only the Operator can access visit statistics.
- Few external scripts: No external tracking scripts are used other than the ad code (Google AdSense) and the visit statistics code (Google Analytics).
12. Privacy officer
The Operator has designated the following privacy officer to oversee personal information processing and to handle related complaints and remedies.
- Name: Seungbeom Kim (Operator)
- Email: developer.ksb@gmail.com
Please send any privacy questions, complaints, or requests for remedies to the email above. The Operator will reply and act without delay.
