What this site records about visits.

This is a personal website. It keeps a small amount of visit data to understand which pages are read and to protect the site from abuse. It does not use advertising, tracking cookies, or third-party analytics.

01What is recorded

The page you opened and, on arrival, the website that linked to it (domain only).
Approximate location (country and city) derived from your IP address by the hosting provider.
Device type, browser, and operating system, derived from your browser's User-Agent.
Your IP address, stored for security review only.
An anonymous daily visitor ID: a one-way hash of your IP address, User-Agent, and a random value that changes every day and is then deleted. It lets the site count unique visitors per day without being able to identify you.

02What is not recorded

No cookies are set for visitors, and nothing is stored on your device for analytics.
No names, emails, or form data, and no cross-site tracking.
Visits from known crawlers and automated tools are discarded.

03How long it is kept

IP addresses are deleted after 30 days.
The remaining, non-identifying visit statistics are deleted after 13 months.
Daily random values are deleted once the day ends.

04Why, and who sees it

Purpose: understanding how the site is used and keeping it secure (legitimate interest).
Only the site owner can see this data, through a sign-in protected dashboard. It is stored with the hosting and database providers (Vercel and Neon) and is not sold or shared.

05Your rights

You can ask what data relates to you, or ask for it to be deleted, by emailing herunhai@outlook.com.
