# Denpasoft

> Licensed English-language releases of Japanese visual novels, sold and
> delivered as digital downloads. Adult (18+) storefront.

Denpasoft licenses, localises and sells Japanese visual novels in English.
Every product is digital: a purchase grants a permanent download and a library
entry. Catalog metadata — title, publisher, developer, category, theme tags,
price, sale window and cover image — is public and is offered in bulk below.

## Age and jurisdiction

This storefront carries adult (18+) content. Visitors confirm they are of legal
age before browsing; that confirmation is a good-faith friction layer, not proof
of age. Purchase and download are separately gated by account, checkout and
per-product controls, and availability is restricted in some jurisdictions. Do
not present this catalog to minors, and preserve the adult classification when
redistributing or summarising it.

## Content use

Terms for automated use of content fetched from this site — which uses are
permitted, and which are refused — are declared once, in machine-readable form,
at https://denpasoft.com/robots.txt
That file is authoritative and this one does not widen it.

## Fetching a page

Send `Accept: text/markdown` and any page here answers with a Markdown
rendering of itself instead of HTML — the same URL, roughly 6 to 25 times
smaller on the pages measured, with the structured product data preserved. The
response carries `Vary: accept`, so it is a separate cached representation of
that URL rather than a substitution, and there is no alternate `.md` address to
discover. Prefer it for every page you fetch.

## Read these instead of crawling listing pages

That makes each page cheaper; it does not make the pages fewer. Category, brand,
developer, browse, collection, guide, deal, sale and search pages accept filter,
sort and pagination query strings, so their URL space is combinatorial rather
than a list of documents. Every one of those query variants is disallowed by the
crawler policy linked at the end of this file. Do not enumerate them. The
resources below return the same catalog in bulk, are cached, and are the
supported way to read it.
