Privacy Policy

Effective September 28, 2026 · Last updated September 28, 2026

Manse Clock (gcdo.kr) is used without any sign-up, and we do not collect users' personal information directly . Cookies are, however, used for advertising and statistics, so those uses are disclosed below.

Article 1 (Information we do not collect)

This site has no sign-up, login, message board or payment features. Accordingly the following information is never collected.

Name, date of birth, gender
Email address, phone number, postal address
Payment information and bank account information
Dates and times the user enters on screen (used for calculation inside the browser only, never sent to a server)

What you look up by tapping a date or a double-hour on screen is calculated entirely inside your own browser. It is neither sent to nor stored on a server, so not even the operator can know what was looked up.

Article 2 (Information recorded automatically)

Running a website means some information is recorded automatically as the server handles access requests. This information is not used for the purpose of identifying individuals.

IP address, access date and time, requested address (URL)
Browser type and operating system, referrer

The above is processed on the servers and security systems of Cloudflare, Inc., to which service provision is entrusted, and is used only to block abnormal access and to compile traffic statistics.

Article 3 (Cookies and advertising)

This site carries third-party advertising to cover its running costs.

Third-party ad providers (Google AdSense and others) use cookies to serve ads based on a user's visit history.
Google may use DoubleClick cookies to display personalized ads based on visits to this site and to other sites.
At Google Ad Settings you can opt out of personalized advertising.
For how third-party ad providers use cookies, please see Google's advertising and cookie policy.
You may refuse cookie storage in your browser settings. Blocking cookies does not stop the Manse calendar calculations from working.

How to block cookies differs by browser. In Chrome it is under Settings → Privacy and security → Third-party cookies, and in Safari under Settings → Safari → Block All Cookies.

Article 4 (Provision to third parties and outsourcing)

Since no personal information is collected, none is provided to third parties either. The following work is outsourced in order to run the service.

Contractor	Outsourced work
Cloudflare, Inc.	Website hosting, content delivery (CDN), security
Google LLC	Serving advertisements (AdSense)

Article 5 (Retention period)

As no personal information is collected directly, there is no separate retention or destruction procedure. The access logs in Article 2 are kept and then deleted according to each contractor's policy.

Article 6 (User rights)

A user may at any time request access to, correction of, deletion of, or suspension of the processing of their personal information. This site, however, holds no personal information, so there is nothing for such a request to apply to. Rights regarding cookies can be exercised directly by the methods in Article 3.

Article 7 (Children under 14)

We do not collect personal information from children under the age of 14. As there is no sign-up process, no processing requiring a legal guardian's consent arises either.

Article 8 (Inquiries)

For inquiries about the handling of personal information, please write to the address given on the contact page.

Privacy Infringement Report Center, Korea (118, privacy.kisa.or.kr)
