Is there a money-back guarantee?

Yes, the Build-a-Book Guarantee. If the studio is not what you expected, write to support within 14 days of your purchase for a full refund. The guarantee lasts 14 days or until you export your 6th coloring book, whichever comes first (a book counts once you export it as a KDP interior, a printable edition or page images; exporting the same book again does not count again). Each studio has its own guarantee: books made in another studio do not count for Coloring Books.
