How can we help?
Answers about buying, using and getting your money back — the FAQ, the license, the refund policy and the terms, all in one place.
Terms
Terms of the store
The terms of buying from and using the store.
Updated
By buying from or using this store you agree to these terms.
Purchases
Prices are shown in US dollars on the English site and in Vietnamese đồng on the Vietnamese site. The price you pay is the one at checkout. Payment is handled by our partners (Polar for cards, PayOS for bank transfers); we never see your card details.
Delivery
Paid orders are delivered by email with a download link, and the link is shown after payment. Keep it private: anyone with the link can download the files.
Products
Products come as described on their pages. What you may do with them is set by the license. Refunds follow the refund policy.
The assistant
Product and algorithm pages have a box where you can ask a question about the page. Your question and the page’s content are sent to Anthropic, whose Claude model writes the answer; Cloudflare Turnstile checks first that a person is asking. We keep your question and its answer, and reuse answers for anyone who asks the same. We do not keep your IP address — only a code made from it that changes every day, to limit how many questions one visitor can ask. Answers are written by AI and can be wrong: the page itself is what counts. Do not put personal information in a question.
Your email
You can leave your email on a product page (“Tell me when it is on sale”), after downloading a free product (“Keep me posted”) or on the home page (“New products by email”). We use it only for what you signed up for, and never sell or share it. With the email we keep the page’s language, the product you signed up about (if any) and a code made from your IP address that changes every day, to stop mass sign-ups — not the IP address itself. Cloudflare Turnstile checks first that a person is signing up. To have your email removed, write to us; every email we send will have an unsubscribe link.
Favorites and recently viewed
Your favorites and the products you viewed are kept in your browser only (localStorage) and never sent to our servers. Clearing this site’s data in your browser clears them.
Liability
Products are provided as they are. We fix problems we are told about, but we are not liable for losses from using them, beyond the amount you paid.
Changes
We may update these terms; the date at the top shows the latest version.
