What we collect
Nothing. There's no sign-up and no account. The site has no tracking, analytics or advertising code, and it sets no cookies.
Your puzzles
Every puzzle is made in your own browser. The words, phrases and settings you type are not sent to us or to anyone else.
Puzzles you play here
When you play a nonogram or killer sudoku on the site, your progress is saved in your browser's storage on this device, so you can come back to it. It is not a cookie, and it never leaves your device. Clearing your browser's data for this site removes it.
Our web host
Cloudflare delivers this site. Like any web host, it handles your internet address to send you the pages and to block attacks. We have added nothing on top of that.
Links to other sites
Links to our books go to Amazon. Amazon's privacy notice applies there.
