Privacy

This book asks nothing of you. There are no forms, accounts, newsletters, comments or advertising, and the pages set no cookies.

What the server keeps

Like any web server, the one that sends these pages keeps short technical logs (the address that asked, the page, the time and the browser) to keep the site running and to stop abuse. We do not combine them with anything else or use them to profile readers.

Typefaces and pictures

The typefaces and every picture are served from this site's own server. Nothing loads from a font service or an image service elsewhere.

Video players

Some chapters show a video from YouTube. Until you press play, the player is only a still picture served inside the page and no request goes to YouTube. When you press play, the video loads from YouTube's privacy-enhanced domain, and YouTube's own privacy policy applies to that video.

Links out

Chapters link to agency pages and, in a few marked places, to stores run by the same team as this book. Those sites have their own privacy terms.
