Terms

Last updated Oct 25, 2026 · Draft: legal review required before launch

Using the studio

PuzzleBook Studio makes puzzle books on your computer. Your books are saved on your device, and you own them.

You’re responsible for what you publish, including word lists and quotes.

Your licence

A purchase gives you a licence for the plan you bought. What you may and may not do with it is on the Licence page.

The studio checks your licence when you’re online, about once a week. If you’re offline it keeps working for 30 days. After that the studio becomes read-only: you can still open your books and export them, and nothing you made is ever locked away.

Each plan allows a set number of devices. Remove a device in Settings to use another.

Payments and refunds

Lemon Squeezy is our merchant of record and takes your payment. The Refund policy gives you 30 days to ask for a full refund, with no usage caps. A refund or a chargeback switches the licence off at its next check.

Cloud backup and your account

Cloud backup is optional. Backups are encrypted and kept for your account; you can restore or delete them in Settings.

You can download everything we hold about you, or delete your account, from Settings → Privacy at any time.

AI features

AI features use your own key, if you add one. What you send and what comes back is between you and your AI provider, and you’re responsible for checking what you publish.

Not Amazon

PuzzleBook Studio is not affiliated with Amazon. KDP decides what it accepts.

Checks are guidance

Preflight follows KDP’s published rules but can’t guarantee acceptance.
