1. Information we collect

The service can be used without signing up; we do not collect information that directly identifies you, such as your name or contact details.

Your IP address, access time, browser and device information, and pages visited may be generated and collected automatically while you use the service.

If you post on the community board, the nickname you choose and the content you write are stored on our server. A nickname need not be your real name, and we recommend you do not enter identifying details.

2. How we use it

Collected information is used only to operate the service, analyze usage to improve it, serve ads, and prevent abuse.

We do not use it to identify or single out individual users.

3. Stored only in your browser

The following stay in your browser's localStorage and are never sent to a server: your watchlist, custom ETFs, saved portfolios and share counts, recent searches, community nickname and likes, day/night theme, KR/US color setting, language, and sidebar state.

Clearing your browser's site data deletes all of it immediately. We cannot read or restore it.

4. Cookies & advertising (Google AdSense)

This service serves ads through third-party providers including Google AdSense.

Third-party vendors, including Google, may collect and use visitors' browser cookies to serve ads and to deliver personalized (interest-based) advertising.

You may refuse cookies in your browser settings and opt out of personalized ads at google.com/settings/ads. Refusing cookies does not affect the analysis features of this service.

5. Usage analytics (Google Analytics)

We use Google Analytics 4 to understand visitor numbers and page usage.

Google Analytics collects anonymized usage records via cookies and does not use them to identify you. You can opt out with Google's browser add-on at tools.google.com/dlpage/gaoptout.

6. Third-party content

Some screens embed TradingView chart and heatmap widgets. Displaying them may transmit your connection information to TradingView's servers, governed by that provider's privacy policy.

7. International transfers

The services in sections 4–6 (Google, TradingView) operate servers outside Korea, so related information may be processed abroad. You can decline via browser cookie controls or each provider's opt-out.

8. Retention

Access logs are kept for up to 3 months from creation for operations and incident response, then destroyed.

Community posts and comments are kept until you delete them or we remove them under section 9.

Retention by Google Analytics and AdSense follows those providers' own policies.

9. Your rights

You may request deletion of posts or comments you wrote at any time, and you can delete browser-stored data yourself.

Send requests to the contact below and we will act without delay. Because the service runs without accounts, we cannot verify identity — please include information that identifies the item (such as the post URL).

10. Sharing

We do not share or sell your information externally except as required by law.

11. Children's privacy

This service is not directed at children under 14, and we do not knowingly collect their personal information.
