Data we receive
Question text, optional display name, optional notification email, private contact details, abuse-prevention signals and normal server logs may be processed. Email addresses are encrypted at rest and are never displayed with public questions.
Why we process it
We use data to review and answer questions, respond privately, prevent spam, secure administration and understand aggregate site performance.
Public questions
Questions remain private until reviewed. Sanghyeon may remove identifying details and lightly edit wording before publication. The management key saved in the submitting browser can edit or delete a pending question; published-removal requests use private contact.
Analytics
Cloudflare Web Analytics measures aggregate visits and page performance. Our own Worker records a small set of aggregate interaction events in Cloudflare Analytics Engine: first use of a travel tool, clicks from a tool to its guide, navigation from the experience hub or an experience comparison card to a public guide, clicks to an official external source and future clearly labeled affiliate links. Event properties are limited to page type, public guide or tool slug, an allowlisted link location and destination hostname. We do not send form values, search text, email addresses, question text, full external URLs or URL query parameters as analytics event properties, and this event system does not set its own cookie or local-storage identifier.
Advertising and cookies
When advertising is activated, third-party vendors including Google may use cookies or similar technologies to serve, limit, secure and measure ads. Google and its partners may use advertising cookies to serve ads based on visits to this site or other sites, subject to the visitor’s settings and consent choices. A browser may also send the page URL, IP address and device or browser information to an advertising provider when an ad request is made.
Visitors can review or opt out of personalized Google advertising in My Ad Center, learn how Google uses information from partner sites, and manage or delete cookies in their browser. Where required, visitors in the EEA, United Kingdom and Switzerland will be shown a Google-certified consent-management message before advertising uses consent-dependent storage or personalization.
Vendors and retention
Cloudflare provides hosting, security, database infrastructure, Web Analytics and aggregate event storage. Interaction events are retained by Analytics Engine for three months. Google will be the advertising provider when AdSense is activated. Any additional affiliate, advertising or email vendor that processes visitor data will be identified here before activation.
Your request
Use private contact for access, correction or deletion requests. Korea KnowHow is independently operated by Sanghyeon from the Republic of Korea; the contact form is the current privacy contact channel.
