This Privacy Policy explains how kzk.kr (“we”, “us”) handles personal information when you use https://kzk.kr in any language. Contact: simhanseog66@gmail.com.
1. Information we collect
- Account data: when you sign up with email and password, we store your email address and a hashed password (we never store your password in plain text).
- Google sign-in: if you choose “Continue with Google”, Google shares your email address, whether it is verified, your name and a Google account identifier. We use these only to create and log in to your account. We do not receive your Google password and do not access your contacts, Drive or other Google data.
- Payment data: paid subscriptions are sold and processed by Gumroad. Your card or payment details are entered on Gumroad and handled by Gumroad and its payment processors; we never see or store card numbers. Gumroad sends us your purchase email, sale/subscription ID and subscription status (active, cancelled, refunded) so we can unlock members-only content.
- Comments: if you leave a comment, we store the name, email and text you submit and your IP address for spam prevention.
- Technical data: our web server keeps standard logs (IP address, browser user agent, requested URL, time) for security and troubleshooting. Your IP address may be looked up in a local country database on our own server to suggest a language; it is not sent to third parties.
2. Cookies
kzk_lang: remembers the language you chose in the language switcher (1 year).pll_language: set by our multilingual plugin to remember the current site language (1 year).wordpress_logged_in_*,wordpress_sec_*,wordpress_test_cookie: keep you logged in and protect your session (session or up to 14 days if you stay signed in).kzk_gst: a short-lived security token used during Google sign-in (10 minutes).- Comment cookies (
comment_author_*) only if you choose to save your details when commenting.
We do not use advertising cookies, and we currently do not use any third-party analytics or tracking tools. Share buttons are plain links and load no third-party scripts. When you open the Gumroad checkout, Gumroad may set its own cookies under its own policy.
3. How we use information
- To create and secure your account and log you in.
- To check whether you have an active paid subscription and unlock members-only guides.
- To reply to your messages and send essential account emails (for example, password resets).
- To keep the site secure and prevent abuse.
We do not sell or rent your personal information and do not send marketing emails without your consent.
4. Sharing and third parties
We share data only with services needed to run the site: Google (sign-in, under Google’s Privacy Policy), Gumroad (payments, under Gumroad’s Privacy Policy) and our hosting provider. We may disclose information if required by law. Some of these providers process data outside your country.
5. Retention
Account data is kept while your account exists. Server logs are kept for a limited period. When you ask us to delete your account, we delete your account data unless we must keep some records (for example, for tax or legal reasons); Gumroad keeps its own transaction records.
6. Your rights
You can ask to access, correct, export or delete your personal data, or withdraw consent, by emailing simhanseog66@gmail.com. Depending on where you live (for example the EU/UK GDPR, Korea’s PIPA, Japan’s APPI or California law) you may have additional rights, including the right to complain to your data protection authority. You can cancel a subscription at any time in your Gumroad library.
7. Children
The site is not directed at children under 14, and we do not knowingly collect their personal information.
8. Changes
We may update this policy. The “Last updated” date shows the latest version; significant changes will be announced on the site.
