Disclaimer

What you can and cannot expect from our books and materials, and how you may use the free materials.

Last updated: 21 October 2026

General information, not personal advice

Casakaya Press books, workbooks and materials offer general information and practical help. They are not personal medical, psychological, legal or financial advice. If you are unsure about your own situation, consult a professional.

De Breinrovers and its teaching materials are not therapy, not a diagnostic tool and not a replacement for professional support. They are meant to complement what parents, schools and specialists already do.

Using the free materials

You may print and use the free materials, such as the Agent Logbook, the mission packs, the school materials and the reflection journals, at home and, in schools, for a whole class.

You may not sell the materials, adapt them and distribute them as your own, or publish them online again. If you want to share them, share the link to the page on casakaya.nl. Texts, illustrations and designs are protected by copyright and remain the property of Carlo Spelbrink.

Use of AI

Casakaya Press uses AI tools in writing, editing and translating text, and for illustrations and design. Despite careful work, texts, translations or illustrations may contain mistakes. If you spot one, please email [email protected].

Buying and external links

Books are sold through Amazon, Payhip, Brave New Books or Boekenbestellen.nl. Price, delivery, payment and returns are handled by that company. Casakaya Press is not responsible for the content of external websites, including the media articles we link to.
