The Service can be used by anyone without account registration. Any text, images, or files you enter into the tools are processed entirely within your browser (client-side) and are never transmitted to or stored on the Service's servers.

However, the following information may be automatically collected for service operation and advertising purposes.

Note: All of the above is anonymized or pseudonymous. The Service does not analyze it directly; we review it only as aggregated statistics through third-party tools such as Google.

• •Service operation, incident response, and security maintenance
• •Usage analytics and service improvement
• •Advertising delivery and optimization via Google AdSense
• •External API calls required by specific tools (e.g., lottery draw lookup, IP address lookup)

Collected information is destroyed without delay once its purpose is fulfilled or its retention period expires. When applicable law requires longer retention, we keep the data only for the period specified by that law.

The Service uses the following third-party services for operation, analytics, and advertising.

• •Google Analytics — anonymized usage analytics
• •Google AdSense — personalized and non-personalized ads
• •Google Tag Manager — analytics and advertising tag management
• •Dhlottery (Korea Lottery) — lottery draw data lookup when using the lottery tool
• •ip-api.com — geolocation lookup when using the IP address tool

Each third party processes data according to its own privacy policy. These external services are only called when you actually use the corresponding tool.

Logs and statistical information stored in electronic form are permanently deleted using non-recoverable methods after the retention period.

The Service uses cookies and similar technologies for usage analytics and personalized advertising. You may refuse cookie storage in your browser settings; doing so may reduce statistical accuracy or limit ad personalization. In jurisdictions where GDPR applies (such as the EU), you can choose your advertising-cookie preferences through the consent banner shown on your first visit.

The Service is not directed at children under 14 years of age, and we do not knowingly collect personal information from them.
