Product and purchase

The American Mahjong Confidence System™ is a digital educational product. Nothing will be shipped. The product description, included materials and price shown at checkout form part of your purchase. Payment is a one-time charge unless clearly stated otherwise.

Digital delivery

Access or download instructions are provided electronically after successful payment. You are responsible for providing a valid email address and compatible equipment.

Personal-use licence

Your purchase grants a limited, non-exclusive, non-transferable licence for personal use. You may print copies for yourself. You may not share, resell, distribute, upload, reproduce for others, teach from commercially or modify the materials for resale without written permission.

Educational disclaimer

The materials provide educational guidance and do not guarantee winning, a score or any specific result. Results depend on practice, judgement, game conditions and tiles drawn. The annual NMJL card is not included.

Refunds

Purchases are covered by the 30-Day Money-Back Guarantee described in our Refund Policy. Nothing limits mandatory consumer rights that cannot legally be excluded.

Intellectual property and acceptable use

Website and product content is owned by or licensed to Tavaria SL. You must not misuse the website, interfere with its operation, attempt unauthorized access or violate applicable law or third-party rights.

Availability and liability

We aim to keep the website and downloads available but do not promise uninterrupted operation. To the maximum extent permitted by law, Tavaria SL is not liable for indirect or consequential loss. Any liability that cannot be excluded is limited only as permitted by law.

Governing law

These terms are governed by the laws of Spain, without depriving consumers of mandatory protections available in their country of residence.
