What Are Cookies
Cookies are small text files stored on your device by your browser. We also use localStorage and similar client-side storage. Together they help us run the site, remember your preferences, and (with consent) measure usage.
Strictly Necessary
These are required for the site to function and cannot be turned off in our system. They are usually set in response to actions you take, such as logging in, switching language, or setting theme preference.
- Authentication / session token (set on login)
- Theme preference (light / dark)
- Language preference (EN / VN)
- Cookie consent state itself
Analytics (Optional)
These help us understand how visitors interact with the site so we can improve it. They are loaded only after you opt in via the cookie banner.
- Google Analytics 4 — anonymized page views, sessions, geography (country only)
- Vercel Web Analytics — privacy-friendly page-view counting
- Vercel Speed Insights — Core Web Vitals measurement
Advertising (Optional)
Used to deliver contextual ads on selected pages. Loaded only after you opt in.
- Google AdSense — contextual advertising and frequency capping
Embedded Content (Optional)
Third-party iframes (e.g. YouTube) may set cookies to remember playback state. We default to privacy-enhanced mode (youtube-nocookie.com); when you opt in, full YouTube cookies become available for features like watch-later.
- YouTube (Google) — embedded video player on article pages
Your Choices
You can change your consent at any time by clicking "Cookie preferences" in the site footer. You can also block cookies in your browser settings, but parts of the site may not work as intended. Consent is re-requested every 13 months as recommended by ePrivacy guidance.
Do Not Track
Browser DNT signals are not yet a standardized opt-out mechanism, so we do not respond to them. Use our cookie banner or your browser settings to control tracking.
