Privacy
Static pages, no accounts, no analytics, no third-party fonts, one saved preference.
Quang Sang is a set of static files. There is no login, no comment system and no reader database.
What this site stores
One thing, and only if you ask for it: the light/dark switch in the header saves your choice in your browser's local storage under the keytheme. It stays on your device, it is not a cookie, it is not sent with any request, and clearing your site data removes it.
Nothing else. These pages set no cookies and run no analytics. If that ever changes, this page changes first.
Server logs
The host serving these files keeps standard request logs — IP address, user agent, path — for operations and security. That is the host's processing, and it is not tied to any identity here.
Retailer links
Following an affiliate link hands you to a third party with its own cookies and its own policy. See the affiliate disclosure.
Fonts and images
Both are served from this domain rather than a CDN, so loading a page here does not tell anyone else that you did.
