Cookie policy
Last updated
In short: This site sets no advertising cookies. It uses Google Analytics to count visits, and stores one preference locally: your choice of light or dark appearance.
Not legal advice. This document has not been reviewed by a lawyer. Where a value depends on legal advice — retention periods, the competent authority, the jurisdiction clause — it states the obligation rather than a specific figure. Have it reviewed by someone qualified in Vietnam before relying on it.
What this site stores
This website uses Google Analytics 4 to understand how many people visit and which pages they read. It runs no advertising, sets no advertising cookies, and shares nothing with advertising networks — advertising storage, advertising user data and ad personalisation are all switched off in the measurement configuration itself, not merely unused.
- Google Analytics (_ga, _ga_*) — set by Google to count a returning visitor as the same person rather than as a new one. Provider: Google Ireland Limited. Duration: up to two years. IP addresses are anonymised.
- Appearance preference — stored in your browser's local storage under the key "pnh-theme" when you choose light or dark mode. It never leaves your device and is not a cookie.
What we do not do
We do not use advertising cookies, tracking pixels for advertising networks, or third-party embedded content that profiles you. We do not sell or share analytics data. We do not attempt to identify individual visitors from it.
Opting out of analytics
You can block analytics for every site you visit with Google's official browser add-on, or by blocking cookies for this site in your browser settings. Doing so does not affect any part of this website.
Controlling storage
Every major browser lets you clear local storage and block cookies from its settings. Clearing storage for this site resets your appearance preference to follow your system setting.
