Who is selling
The guides on this site are written by Viktor (sole proprietor), Ukraine. The sale itself is handled by Paddle.com Market Ltd, which acts as the merchant of record. That means Paddle takes your payment, issues the receipt and charges any sales tax or VAT that applies where you live. Paddle's own terms apply to the payment: paddle.com/legal/checkout-buyer-terms.
What you are buying
You are buying a licence to use one PDF file for yourself and the people in your household. You may print it as many times as you like for your own use. You may not sell it, post it online, or pass copies to other people. The file stays the property of the author.
How you get it
After payment, an email with a download link goes to the address you gave at checkout. The link works for 7 days. If it expires, or the email does not arrive, write to [email protected] and we will send a new one.
What this is not
The guides are general information written in plain language by a person who is not a doctor. They name their sources so you can check them. They are not medical advice, they do not diagnose anything, and they do not replace a doctor who can examine you.
Refunds
When and how we refund is set out in the refund policy.
