Privacy Policy

This Privacy Policy explains how Tejune Kang ("we," "us," or "our") collects, uses, shares, and protects information about visitors to tejunekang.com and any subdomains (collectively, the "Site"). By using the Site you agree to the practices described here. If you do not agree, please do not use the Site.

1. Information We Collect

Information you provide

We collect information you give us directly, such as when you submit the contact form, subscribe to a newsletter, request a resource, send an email, or otherwise communicate with us. This typically includes name, email address, organization, role, country, and any message content you provide.

Information collected automatically

When you visit the Site we automatically collect certain technical data, including: IP address (often truncated by analytics providers), device type, browser type and version, operating system, referring URL, pages visited, time spent, language preference, and approximate location derived from IP. This information is used to operate, secure, and improve the Site.

Information from third parties

We may receive information about you from third-party platforms when you interact with our content there — for example, when you click a link, like, follow, comment, watch a video, or share content from our profiles on LinkedIn, X (formerly Twitter), TikTok, YouTube, Instagram, or Meta/Facebook. The data made available depends on each platform's settings and your privacy controls on that platform.

2. How We Use Information

Operate, maintain, secure, and improve the Site;
Respond to inquiries, deliver requested resources, and communicate about engagements;
Send newsletters and updates you have opted in to receive;
Measure aggregate traffic, performance, and content engagement (analytics);
Personalize content where appropriate (for example, language or region);
Detect, prevent, and address fraud, abuse, security incidents, and technical issues;
Comply with applicable law, legal process, or enforceable governmental request.

We do not sell your personal information. We do not share personal information with third parties for their own independent direct-marketing purposes.

3. Legal Bases (EEA / UK Visitors)

If you are in the European Economic Area or United Kingdom, we process your personal data under one or more of the following legal bases: (a) your consent (e.g., newsletter subscription, non-essential cookies); (b) performance of a contract or pre-contractual steps you request; (c) our legitimate interests in operating, securing, and improving the Site, where those interests are not overridden by your rights; and (d) compliance with legal obligations.

4. Cookies & Similar Technologies

We use cookies and similar technologies (such as local storage and pixels) to operate the Site, remember preferences (e.g., language), and measure traffic. Categories used:

Strictly necessary — required for core Site functionality and security.
Performance / analytics — help us understand how visitors use the Site (see Section 5).
Functional — remember preferences such as language switcher selection.

You can manage cookies through your browser settings. Blocking some cookies may affect Site functionality.

5. Analytics & Advertising Partners

We use Google Analytics 4 (property G-RJB3KLVF41) to measure aggregate Site usage. Google Analytics may set cookies and collect data such as IP address (typically anonymized), device, browser, pages viewed, and referral source. Learn more in Google's Privacy Policy. You can opt out using the Google Analytics Opt-out Browser Add-on.

The Site may also include affiliate links (including the Amazon Associates program). When you click an affiliate link and make a qualifying purchase, the merchant may share limited information with us so the referral can be credited.

We maintain official presences on third-party platforms — including, without limitation, LinkedIn, X (Twitter), TikTok, YouTube, Instagram, and Meta/Facebook — and may embed or link to content hosted on those platforms. When you visit, follow, or interact with our content on a third-party platform, that platform collects information about you under its own terms and privacy policy. We may receive aggregate or pseudonymous analytics from the platform (for example, number of views, follower demographics, engagement metrics) but do not control the platform's underlying data practices. Please review the privacy policies of each platform you use:

We share personal information only as described in this Policy — namely with:

Service providers who process information on our behalf (hosting, email delivery, form processing, analytics) under contractual confidentiality and security obligations;
Professional advisors such as attorneys and accountants where reasonably necessary;
Authorities when required by law, legal process, or to protect rights, safety, or property;
Successors in connection with a merger, acquisition, financing, or sale of assets, subject to standard confidentiality protections.

8. International Data Transfers

The Site is operated from the United States. If you access it from outside the U.S., your information may be transferred to, stored, and processed in the United States or other countries with data-protection laws different from those of your country. Where required, we rely on appropriate safeguards such as Standard Contractual Clauses.

9. Data Retention

We retain personal information only for as long as needed for the purposes described in this Policy, to comply with legal obligations, resolve disputes, and enforce agreements. Newsletter subscribers' contact data is retained until they unsubscribe. Contact-form submissions are typically retained for up to 36 months unless a longer period is required.

10. Security

We use reasonable administrative, technical, and physical safeguards designed to protect information collected through the Site. No method of transmission or storage is 100% secure, however, and we cannot guarantee absolute security.

11. Your Rights & Choices

Depending on where you live, you may have the right to: access the personal information we hold about you; request correction or deletion; object to or restrict certain processing; withdraw consent; receive a portable copy; or lodge a complaint with your local data-protection authority. To exercise any of these rights, contact us through our contact form. We will respond within the time period required by applicable law.

You can unsubscribe from marketing emails at any time using the unsubscribe link in any email or by contacting us directly.

12. California Privacy Rights (CCPA / CPRA)

If you are a California resident, you have the right to know what personal information we collect, use, disclose, and (if applicable) sell or share; the right to delete personal information we hold; the right to correct inaccurate personal information; and the right to non-discrimination for exercising these rights. We do not sell or share personal information for cross-context behavioral advertising as those terms are defined under the CCPA/CPRA. To exercise your rights, contact us through our contact form.

13. Children's Privacy

The Site is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information through the Site, contact us so we can delete it.

14. Do Not Track Signals

Some browsers transmit "Do Not Track" (DNT) signals. There is no industry-standard interpretation of DNT, so the Site does not currently respond differently when a DNT signal is received.

15. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the most recent revision. Material changes will be flagged on the Site. Continued use of the Site after changes take effect constitutes acceptance of the revised Policy.
