This page describes what the site collects today. It is written from how the site is actually set up, and changes when the setup changes.
Reading the site
The site counts visits with its own privacy-friendly analytics. It records which page was read, roughly how long and how far, the kind of device, and where the visit came from (for example a search engine). It does not store your IP address. It sets no cookies, and the identifier it uses is a one-way hash that changes every day, so it cannot follow you from one day to the next. If your browser sends Do Not Track or Global Privacy Control, nothing is recorded.
Searches you make on the site are used to show you results and are not stored.
Links to other sites
Articles link to other websites, and some links (to shops, for example) carry a tracking tag from the shop. Those sites have their own privacy policies.
