Privacy & contact
Short version: this site does not track you, does not show ads, and runs no analytics or advertising cookies. The puzzles work with no account at all. There is one optional account, it belongs to a grown-up, and this page lists exactly what it holds.
What we collect
On the puzzle pages, nothing. There is no analytics script, no advertising pixel, no social embed, and no third-party service running on this page. If you choose to make an account, what that stores is listed under Accounts below.
What stays in your browser
Two things are saved on your own device, using your browser's local storage, so the site remembers them between visits:
- The book code you entered, so you do not have to retype it.
- Puzzles you have solved — which chapter, how many pieces, the date, and how long it took.
This never leaves your device. We cannot see it. Clearing your browser data deletes it permanently, and we have no copy to restore.
Pictures you upload
When you photograph a colored page and load it in, the picture is read by your browser and drawn onto the page. It is not uploaded to a server. It never leaves your device, and closing the tab discards it.
Accounts
An account is optional. Every puzzle on this site works without one, and nothing is kept back for people who sign up.
It is for grown-ups. Signing in means typing your email address and clicking a link we send you; there is no password to remember. If you make one, we store:
- Your email address, and when you last signed in.
- Which book copies you have claimed, so you can reprint their pages.
- Puzzles solved while signed in — which chapter, how many pieces, how long it took, and how many clues were used.
- Puzzles you started while signed in — which chapter, how many pieces, and the moment the board was handed to you. This is how a leaderboard time is measured by us rather than taken on trust, so a board only shows solves we timed ourselves. A board you start and never finish leaves one of these behind and nothing else.
- Your clue balance, and the purchases that added to it.
- Whether you have asked to appear on leaderboards, and whether that includes solves recorded before you asked. Both are off unless you turn them on, and turning them off again removes you.
- Which generated nickname you appear under on a leaderboard — a number, not a name. We pick the words from a fixed list; there is no box to type your own, so nothing you write can ever appear on a public page.
Staying signed in uses one cookie, set by puzzlebooks.club itself. It keeps you logged in and does nothing else. There is no third-party cookie and nothing here follows you to other sites.
Email hello@puzzlebooks.club and we will delete your account and everything attached to it.
Children
This site is made for children to use. Children never sign in. There are no child accounts, no child profiles, no age question, and no way for a child to type anything that other people can see. The account described above belongs to a parent, and there is nothing here for a child to sign up for.
If that ever changes, this page will be updated before the change ships, not after.
Book codes
The code printed in a workbook identifies the title and copy, not a person. Entering it opens that volume's pages, and that check happens on your own device. If you are signed in and claim a copy, we record that your account holds it, so you can reprint its pages later.
