Reporting a bug

Puzzle generation is deterministic, which means almost any bug can be reproduced exactly if you include enough to rebuild the puzzle. The most useful report contains:

• What you expected and what happened instead.
• The puzzle type, and the trim size and page count if it is an export or cover problem.
• Your browser and operating system.
• If a book is involved, the exported project file — it contains the recipe, not the finished pages, so it is small.

Licence and billing

Purchases are handled by Polar, who send the licence key by email. If a key has not arrived, check spam first, then email me with the address you used — I can look it up and resend.

Before you write

A few answers live elsewhere: what the free version includes and what selling requires is on the commercial use page, and the print specifications Amazon enforces are on the KDP specs page.
