Cookie policy
Applies to the NAD Technologies website.
Language preference cookie
The nad_locale cookie remembers Vietnamese or English for up to one year. Manual preference takes priority when returning to the root URL. You can remove it in your browser.
Administration cookie
The nad_admin cookie authenticates an administrator for up to eight hours with HttpOnly and SameSite=Strict. Signing out removes it. It is not used for advertising tracking.
Theme preference
Your light or dark choice is stored in localStorage on this device. Without a saved choice, the site follows your device theme setting. Clearing site data in your browser removes the saved preference.
Location-based language selection
When the hosting infrastructure provides a trusted country code, the root URL selects Vietnamese for Vietnam and English elsewhere. GPS permission is not requested. Without country information, browser language is used.
