Privacy policy

This is a static website. There is no login, no user account and no comment system. This page lists everything that does involve data — and nothing else applies.

Last updated: 17 October 2026.

What we do not collect

No analytics scripts, no advertising pixels, no visit tracking by us.
No cookies set by this site's own code.
No account, no profile, no behavioural history.

Hosting logs

The site is served by Cloudflare Pages. Cloudflare processes standard request data — IP address, user agent, requested URL, timestamp — in order to serve the pages and protect the site, under Cloudflare's own privacy policy. Individual visit records are not something we receive, export or analyse.

The newsletter is optional and involves exactly one thing: the email address you type into the form.

It is stored with the newsletter provider that operates the signup form, and used only to send the monthly email.
Every issue carries a one-click unsubscribe link. Unsubscribing removes you from the list.
The address is never sold, rented or handed to a merchant.

Affiliate links

Some outbound links are affiliate links — the mechanics are described in full in the affiliate disclosure. When you click one, the retailer or affiliate network may set a cookie so the sale can be credited to this site. That cookie is set by them, under their policy, and carries a click identifier rather than your identity. Your order details, address and payment information never reach us.

Email you send us

If you write to 352312766@qq.com — a correction, a complaint, a licensing question — the message and the address are kept only as long as needed to deal with it. They are never added to a mailing list without your explicit request.

Your rights

Write to the address above to ask what is held about you, to have it corrected, or to have it deleted. If the only record we hold is a newsletter subscription, deletion is immediate.

Children

This site is written for adults looking after their own hardware. It is not directed at children and does not knowingly collect data from anyone under 16.

Changes

If this policy changes, the date at the top changes with it. There is no archive of earlier versions, because there is nothing to archive: no accounts and no stored profiles.
