Terms of service

Last updated 11 November 2026.

The service

Puzzzlo is a web tool that makes puzzle book interiors (PDF files) for print, for example for Amazon KDP. It is run by Zaqi Fathis, Germany. Contact: [email protected].

Free use

You can use every setting and preview without an account. Free exports hold up to 10 puzzles and carry a small credit line.

Buying a tool

• A tool is a one-time purchase through Gumroad, which processes the payment as merchant of record. Gumroad's terms apply to the payment, receipts and refunds.
• The purchase unlocks the tool on the Puzzzlo account with the purchase email (or the account where you redeem the license key). There is no subscription and no device limit. Please keep your account to yourself.
• A refunded purchase no longer unlocks the tool.

Your books

The puzzles and PDFs you generate are yours: you may publish and sell books made with them, including on Amazon KDP. You are responsible for your book's title, cover and listing. We do not promise that a marketplace will accept a book.

Availability and changes

We work to keep the service available but cannot promise it is never down. We may improve or change features; a tool you bought stays usable for as long as we run the service.

Liability

We are liable without limit for intent and gross negligence and for injury to life, body or health. For slight negligence we are liable only for breach of essential obligations, limited to the damage typical and foreseeable for this kind of service.

Law

German law applies. If you are a consumer, this does not take away protections of the law of the country where you live.
