Terms of service

Plain-language terms. By using Katarineko you agree to them. Updated 2026-08-17.

The service

Katarineko generates personalized Japanese reading material and study tooling from the vocabulary of films you choose. Story generation and the learner workspace require a paid subscription, billed through Clerk. You can cancel any time; access runs to the end of the paid period.

Honest limits

Katarineko is a learning tool, not a guarantee. We do not promise fluency, certification outcomes, or timelines beyond what the material itself says. Language learning depends on what you put in.

Content and trademarks

Film titles are used to identify the works; all film trademarks and copyrights belong to their owners, and Katarineko is affiliated with none of them. Our analyses, statistics, generated stories, and site text are ours; don't republish them wholesale without asking.

Accounts

Keep your account yours: one learner per account. We may suspend accounts that abuse the service or attempt to extract the product's generated content in bulk.

The legal frame

Katarineko is operated from Spain, and these terms are governed by Spanish law. Questions first, lawyers later: marce@katarineko.com.
