Kitsumi
Copyright (c) 2026 Olexify. All rights reserved.

Kitsumi is free to use. It is not open source.


No permission is granted to copy, modify, merge, publish, distribute,
sublicense, sell, reverse engineer, or create derivative works from any part of
Kitsumi, in whole or in part, without prior written permission from the
copyright holder. This applies to the source code, and equally to the compiled
extension package distributed through the Chrome Web Store, addons.mozilla.org
and the Opera add-ons site.

Having access to the source code grants no licence to use, copy, or
redistribute any part of it. The fact that a browser extension package is
readable once installed or downloaded does not place its contents in the public
domain and does not grant any licence to reuse them.


The extension package also contains software and data that is not Kitsumi's,
under open licences that grant you rights this licence cannot take away.
Section 1 does not apply to those components. Each is governed by its own
licence, and those licences prevail over anything here.

Every one of them is listed, with its licence and the path to the full licence
text inside the package, in THIRD-PARTY-NOTICES.txt. The same list is readable
inside the extension at Settings, About & legal, Third-party licences. In
summary:

Tesseract.js; the Tesseract OCR engine compiled to
WebAssembly, which links Leptonica, libpng and libtiff;
and the Japanese vertical recognition data Apache License 2.0

fflate MIT

Kanji usage frequency data, by Dmitry Shpika, modified CC BY 4.0

Dictionaries downloaded through Kitsumi are not part of the package. They are
fetched from third-party hosts at the user's request, and each keeps whatever
licence its publisher gave it.


Documentation in Kitsumi's repositories, meaning the README and other Markdown
files, may be quoted for review, commentary and reporting purposes, with
attribution.


Kitsumi is provided "as is" and "as available", without warranty of any kind,
express or implied, including but not limited to the implied warranties of
merchantability, fitness for a particular purpose, title, and
non-infringement. No advice or information obtained through Kitsumi, whether
spoken or written, creates any warranty not stated here.

Kitsumi displays material that comes from third-party websites, files and
services outside the copyright holder's control. There is no guarantee that
any subtitle, dictionary entry, translation, recognised text or generated card
is accurate, complete or fit for any purpose, nor that any third-party service
will remain available or keep working as it does today.


To the maximum extent permitted by applicable law, the copyright holder is not
liable for any indirect, incidental, special, consequential or exemplary
damages, nor for any loss of or damage to data, loss of profits, or
interruption of study or work, arising out of or in connection with Kitsumi or
its use, whether the claim is founded in contract, tort or otherwise, and even
if the possibility of such damage was known.

Where liability cannot lawfully be excluded, it is limited to the amount you
paid for Kitsumi, which is nothing.

Nothing in this licence excludes or limits liability for death or personal
injury caused by negligence, for fraud or fraudulent misrepresentation, or for
anything else that applicable law does not allow to be excluded or limited. If
you are a consumer, this licence does not affect your statutory rights.


Kitsumi is a tool. It hosts no video, no subtitles and no dictionaries, and it
supplies no copyrighted content of its own. What it shows you comes from the
page you are on, from files you provide, or from third-party services you
choose to enable.

You are responsible for having the right to access that material, and for
complying with the terms of the sites and services you use Kitsumi with.
