Cookie policy
Last updated
In short: This site sets no advertising or tracking cookies. It 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 does not use advertising cookies, tracking pixels or third-party analytics in its current form.
- 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.
If you add analytics
[If you introduce analytics, advertising or embedded third-party content, this page must be updated to list each cookie, its purpose, its duration and its provider — and in most jurisdictions you will also need a consent mechanism that blocks those cookies until consent is given.]
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.
