Privacy Policy

Effective / last updated: 2026-06-25

1. Information we collect and do not collect

InvestGyesan has no sign-up process and does not request or collect directly identifying information such as your name, contact details or account numbers. Values you enter into a calculator — buy price, sell price, quantity, dividends, etc. — are used only within your browser, are discarded automatically, and are not transmitted to or stored on the operator's server.

However, the following information may be generated and collected automatically while you use the website.

• Access IP address, browser type and version, operating system, visit date/time
• Pages visited, previous page (referrer), device information
• Anonymous identifiers via cookies and similar technologies

2. Use of cookies

InvestGyesan may use cookies to provide the service and display ads. A cookie is a small text file that a website stores in your browser to remember visit history and settings.

You can refuse or delete cookies in your web browser settings. However, blocking cookies may limit some features and ad personalization. Cookie settings can be changed in the settings menu of each browser (Chrome, Safari, Edge, etc.).

3. Google AdSense and third-party ads

InvestGyesan serves ads through Google AdSense. Third-party ad vendors, including Google, may use cookies to serve personalized ads based on your prior visits.

• Google uses advertising cookies (e.g., the DoubleClick cookie) to serve ads based on your visits to this and other sites.
• You can opt out of personalized advertising in Google Ads Settings.
• You can review and opt out of third-party ad vendor cookie use at www.aboutads.info.
• You can learn how Google processes data at the How Google uses data from partner sites page.

4. Analytics tools

To improve the service, we may use web analytics tools such as Google Analytics. These tools collect anonymized statistics such as pages visited and time on site via cookies, and do not identify any specific individual.

5. Data retention and third-party sharing

Because InvestGyesan does not directly collect or store your personal information, no separate retention period applies. Automatically collected access information and cookie data are processed and retained according to the policies of the relevant service providers such as Google. The operator does not sell or arbitrarily provide your information to third parties except as required by law.

6. Your rights

You have the right to refuse information collection through your browser cookie settings, and you can disable personalized ads in Google Ads Settings. For inquiries about personal data processing, contact us at the address below.

7. Children's privacy

InvestGyesan is not primarily directed at children under 14 and does not knowingly collect children's personal information.

8. Changes to this policy

This privacy policy may be revised due to changes in law or the service, and we will announce changes via this page. For significant changes, we will update the effective date.
