Privacy Policy

Last updated: October 5, 2026

Welcome to ChenDermatologist. This policy explains what information may be collected when you use this website, how it is used, and what choices you have.

1. Information and Browser Storage

1-1 Information You Provide

Public reading does not require an account or your name, national ID number or medical record. Author sign-in, drafts and media are separate management functions. If you use the footer email link to contact us, the information you send is processed through the email service.

1-2 Technical Data

Vercel hosts this website. When pages and third-party resources load, providers may receive IP addresses, browser information, page paths, timestamps and other technical data needed to operate, secure and maintain the services. Processing and retention differ by service; see the relevant privacy notices.

1-3 Cookies and Local Storage

The first-party dn_lang cookie remembers your language choice for 365 days. Browser storage remembers language, theme, font size, read articles and reading position. Author drafts may also be stored locally in the browser used for editing. GA4 may use identifiers and cookies as described below. The Microsoft Clarity script is currently disabled.

You can clear cookies and site storage or block third-party cookies in your browser. Preferences and reading memory may reset; authors should confirm that drafts are saved before clearing local storage.

2. Third-Party Services

2-1 Google Analytics 4 (GA4)

This website uses GA4 for page views, reading progress and site navigation to improve content and reading. Custom analytics events do not include the search terms you enter; page and link URLs sent by those events omit query strings and fragments. GA4 may still process cookies, technical identifiers, device information and coarse location data. This does not mean that all analytics data is fully anonymous. See the Google Privacy Policy.

2-2 Microsoft Clarity (Disabled)

This website currently does not load Microsoft Clarity or enable its click recording or session replay. Stopping the script does not automatically delete data already held by the service. See the Microsoft Privacy Statement for information about the provider's data handling.

2-3 Search Console and Webmaster Tools

Google Search Console and Bing Webmaster Tools verify site ownership, submit sitemaps and report search performance. Using these management tools does not require readers to provide personal information to this website.

2-4 Google Fonts and Local CSS

Fonts may be loaded from Google Fonts. The main site styling is served from local CSS files and no longer depends on the Tailwind CDN. Google Fonts may receive your IP address when font resources are requested.

2-5 Vercel Speed Insights

This website uses Speed Insights for loading, interaction and layout-stability measurements. Vercel describes data points such as page paths, device and browser types, country and Web Vitals, without reconstructing browsing sessions across pages. This differs from general hosting logs. See the Speed Insights privacy documentation.

2-6 Advertising Status

AdSense is currently disabled. This policy will be updated if advertising is enabled.

3. How We Handle Information

  • We do not sell, rent or trade your personal data.
  • Reading public articles does not require medical records, symptom descriptions or photographs.
  • If you email us, we may reply by email. Reading articles alone does not provide us with your email address.

4. Your Choices

For access, correction, deletion or processing questions, use the email link in the website footer. For third-party processing and opt-out options, consult each provider's privacy information.

Clearing browser cookies and site storage removes preferences and identifiers on this device. It does not automatically delete data already sent to third-party services; requests for data held by providers follow their procedures.

5. Children

This website is intended for general educational reading. It does not knowingly collect personal information from children under 13.

6. Updates

This policy may be updated when services, laws or technical settings change. Material changes will be reflected on this page.

7. Contact

For privacy questions, use the footer email link. The About page explains the site's educational purpose.
