Effective 22 September 2026

Cookie Policy

This policy explains the purpose, lifespan, and visitor control of cookies and similar storage mechanisms used on Wridian pages. Cookies are small text files stored by a browser and can be cleared through browser settings. Wridian uses them for core navigation and optional analytics. A visitor can reject non-essential cookies through the banner and manage all stored data via browser preferences.

1. What is a cookie?

A cookie is data stored in a browser under a domain's control. It can persist across page visits or expire when a session ends. Local storage and session storage work similarly but may have different lifespans. Wridian uses these mechanisms sparingly and informs visitors through the banner when a choice is available.

2. Essential cookies

The cookieChoice item stores the visitor's accept/reject decision for the cookie banner. This is an essential browser storage value; without it, the banner cannot remember that a choice was made and would ask repeatedly on every visit. It expires after 12 months or when the browser's stored data is cleared. This storage item is not optional because it is necessary for the banner to work as intended.

3. Analytics cookies

If analytics are implemented, they will appear on this page with the provider name, purpose (e.g., page views, session duration), and data retained duration (typically 13–26 months). Analytics track usage patterns to identify broken pages, popular topics, and unexpected traffic changes. They do not identify individuals; data is aggregated by country, device type, or browser family. Visitors reject analytics at setup or clear them anytime through browser preferences.

4. Marketing and advertising cookies

Wridian does not place marketing or advertising cookies. Third-party platforms used for ads (if any exist on linked partner sites) have their own cookie policies. Wridian has no control over those cookies and recommends reading the partner's policy.

5. Technical functionality

Standard HTTP headers, server logs, and transport protocols may include technical data such as IP address, user-agent, and timestamp. These are operational rather than cookie-based storage but serve similar purposes: diagnosing connection issues, detecting unusual access patterns, and measuring response times. They are retained for 90 days unless an incident investigation extends retention.

6. How to manage cookies

All browsers allow management of cookies through settings or preferences, typically under Privacy or Security. A visitor can block all cookies, allow only some, delete existing cookies, or set an auto-clear policy. Blocking some cookies may reduce functionality; others can be blocked with no impact on reading.

7. Cookie consent

The cookie banner appears the first time a visitor reaches Wridian. Rejecting analytics means those cookies are never placed; accepting means they are activated after the choice is recorded. A visitor can change a choice by clearing the cookieChoice value and returning to any page.

8. Third-party cookies

If Wridian embeds external content (such as a video player or map), that provider may set its own cookies. Wridian does not consent to those cookies on a visitor's behalf and recommends reading the provider's policy. A visitor can clear embedded provider cookies through browser settings.

9. Data retention

The cookieChoice item persists for 12 months unless deleted by the visitor. Analytics cookies (if implemented) follow the lifespan listed in Section 3. Server logs are rotated after 90 days unless a security incident is under review. Visitors can request deletion of their choice data through the privacy policy process.

10. Do Not Track

Browsers may send a Do Not Track signal. Wridian respects this signal by not loading optional analytics when a visitor's browser indicates the preference. The essential cookieChoice item is still placed because it is necessary for the site to function without asking again.

11. Updates

Version 1.0 was published on 22 September 2026. If Wridian adds new analytics, advertising, or third-party integrations, a new version of this policy will be published and the effective date changed. The banner will prompt visitors to review and re-confirm their choice.

12. Questions

Contact Wridian at +82 2-3486-7129 or through the contact form with questions about a specific cookie's purpose or how to clear it. The editorial desk can identify which storage item caused an unexpected behavior and explain how to adjust browser settings if needed.

The essential preference is named wridian_cookie_choice and normally lasts 12 months. It records only a consent state such as accepted, rejected, or pending; it does not contain a name, email address, wallet identifier, or message content. A temporary session value may be used while a form is open and is removed when the browser session ends. These values support the site's basic controls rather than advertising.

Optional analytics, if enabled, may use provider cookies such as _ga and _ga_*, with a typical lifespan of up to 13 months from the last interaction. They may also use short-lived identifiers to distinguish one visit from another. The exact provider, purpose, and retention period will be listed before activation where consent is required. Rejecting analytics leaves navigation and editorial reading available.

Visitors can withdraw or change a cookie choice by clearing the browser's site data and revisiting the consent control, or by contacting Wridian at +82 2-3486-7129. Browser settings can block third-party cookies, delete individual items, or warn before storage is written. Blocking essential storage may cause the banner to reappear or prevent the site from remembering a preference, but it should not prevent access to ordinary articles.

Some linked services may set their own cookies when a visitor opens them. Those cookies are controlled by the linked service, not by Wridian, and their names and lifespans are described in the provider's own policy. Wridian does not use cookies to infer sensitive traits, reconstruct private keys, or make individualized financial decisions. If a future feature changes this practice, this page and the consent notice will be updated before the relevant optional storage is used.

This policy was reviewed on 22 September 2026. We retain a record of configuration changes so that a visitor can understand when a cookie name, provider, purpose, or lifespan changed. Questions about stored data can be sent through the contact page; we generally acknowledge them within five business days and respond with available technical details within 30 days.

The essential preference item is named cookieChoice and normally lasts 12 months. It records a consent state such as accepted, rejected, or pending and does not contain a name, email address, wallet identifier, or message content. A temporary session value may be used while a form is open and expires when the browser session ends. Clearing site data removes these values, which may cause the banner to appear again.

Optional analytics may use names such as _ga and _ga_* when an approved provider is enabled after consent. A typical analytics lifespan is up to 13 months from the last interaction, with shorter session identifiers used to group page requests. The provider, purpose, region, and retention period should be shown in the consent information before optional storage is activated. Rejecting analytics does not disable ordinary reading, navigation, or the contact route.

Wridian does not intentionally place marketing or advertising cookies for behavioral targeting. A linked third-party service may set its own storage after a visitor leaves Wridian, and that service controls its own names, purposes, and deletion rules. Embedded resources are reviewed so that optional storage is not introduced without an appropriate notice where consent is required. If this practice changes, the cookie notice and this policy will be updated before the change is used.

Visitors can withdraw or change a choice by clearing the browser's stored data and revisiting the consent control. Browser settings can block third-party cookies, delete individual items, or warn before storage is written. Blocking essential storage may prevent the site from remembering a choice and may make the banner reappear, but it should not prevent access to ordinary articles. Contact questions can be sent through the site or by calling +82 2-3486-7129.

Cookie configuration is reviewed when the banner, analytics, forms, or linked services change. This page was reviewed on 22 September 2026, and a material change will receive a new date and a short explanation of the affected name, provider, purpose, or lifespan. We aim to acknowledge a technical storage question within five business days and respond with available details within 30 days.
