Privacy
Updated
This site has no advertising and sets no cookies at all — not one, first-party or third. Two things send data to a server: a count of page views, and the like button. This page says what each one sends and what is kept.
What your browser stores
Two values live in your browser and are never sent anywhere. theme remembers whether you chose light, dark, or system. liked-articles is the list of articles you have liked, so the heart is still filled when you come back.
Clearing this site’s data removes both. Neither is a cookie, so neither is attached to any request.
Page views
Every page load is counted, using Vercel Web Analytics. No cookie is set and nothing is written to your browser. One visit is told apart from another by a hash Vercel computes from the request itself, and that hash is discarded after 24 hours — so a visit today and a visit next week are not connected.
Each view records the time, the page, the site you arrived from, your browser and operating system with their versions, your device type, and an approximate location — country, region and city — worked out from your IP address. The address itself is not stored alongside the record, and none of this is used to follow you to other sites.
This is more than the like button stores, and unlike the like button it happens without you doing anything. It is here so I can tell which articles are worth writing more of. The script is served from this site’s own domain rather than a third party’s, which also means a content blocker may not recognise it.
Likes
Liking an article sends the article’s identifier and, unavoidably, your IP address — every request on the web carries one.
Two things are then stored: a running total per article, and a record that a like is currently active. That record is keyed by a SHA-256 hash of your IP address combined with a secret that never leaves the server, and it deletes itself after 30 days. The hash cannot be turned back into an address without the secret.
Your address itself is never written down. There is no account, no cookie, and nothing connecting a like to anything else you have read here.
Search and sharing
Search runs entirely in your browser against an index served from this site. What you type never leaves your machine.
The share buttons are ordinary links. No vendor script is loaded and no request reaches X, Bluesky, Hatena or anyone else until you click one. Fonts are served from this site rather than from Google.
Hosting
The site is hosted on Vercel, which keeps its own request logs — address, page, timestamp — as every web host does. That is outside what this site controls, and it is worth knowing rather than glossing over.
Vercel is also the company that receives the page-view data described above, so one operator holds both. Nothing from this site is sent to anyone else.
Corrections
If anything here is wrong or unclear, the More menu at the end of every article reaches me.
