Terms
Clear terms for a digital guide.
By completing a purchase, you agree to the final price, delivery terms, and provider terms displayed at checkout.
Product and access
The product is a personal-use digital PDF. A completed payment grants the purchaser a non-transferable right to read and print the guide for personal use. Resale, public redistribution, and commercial reproduction are not permitted.
Health boundary
The guide and website provide general education. They do not diagnose, prescribe, replace professional care, or promise a health outcome. Individual decisions remain the responsibility of the reader and their qualified professionals.
Price and delivery
The final price and currency appear immediately before payment. Protected digital access is supplied after the payment provider confirms the order.
Availability
Access may be paused for maintenance, safety, legal, or technical reasons. Applicable consumer law remains unaffected.
