# Third-Party & Open-Source Notices

The open-source software Khata is built on, the licences it is used under, and where to get the licence texts.

Version 1.0, effective 2026-08-29. Reference LSK-LEGAL-OPEN-SOURCE-V1.0.

## At a glance

This is a reading aid, not the agreement. The clauses below are.

- Khata is built on open-source software, used under permissive licences.
- This lists the website's runtime dependencies, verified on 29 August 2026.
- Those licences cover the components, not Khata itself — see the Licence & Conduct document for that.
- Ask us and we will send the full licence texts.

## 1. Why This Document Exists

1.1 The permissive licences Khata's components are published under — MIT, ISC, BSD-2-Clause and Apache-2.0 — allow commercial use and redistribution, and require that the copyright notices and licence text are preserved.

1.2 **(important)** This document is how we preserve them. It is an attribution notice, not a grant: nothing here gives you a licence to Khata itself, which is governed by the Licence & Conduct document.

## 2. Scope Of This List

2.1 **(important)** What follows is the runtime dependency set of the Khata website (lskhata.com), read from the installed package tree on 29 August 2026.

2.2 It is not a complete bill of materials for the whole product. The mobile app and the server API have their own dependency trees, which are not enumerated here. If you need those — for a procurement review or a security assessment — ask and we will produce them rather than pointing you at this page.

2.3 Transitive dependencies are not listed individually. The direct dependencies below pull in further packages, all under permissive licences.

## 3. Framework And Runtime

3.1 The application framework and rendering layer:

  - next 15.5.22 — MIT — Vercel, Inc.
  - react 18.3.1 — MIT — Meta Platforms, Inc. and affiliates
  - react-dom 18.3.1 — MIT — Meta Platforms, Inc. and affiliates

## 4. Interface Components

4.1 Accessible primitives and interface utilities:

  - @radix-ui/* — 22 packages — MIT — WorkOS, Inc.
  - class-variance-authority 0.7.1 — Apache-2.0 — Joe Bell

  - framer-motion 11.18.2 — MIT — Framer B.V.
  - embla-carousel-react 8.6.0 and embla-carousel-autoplay 8.6.0 — MIT — David Jerleke

## 5. Forms, Data And Documents

5.1 Input handling, validation, charting and PDF generation:

  - react-hook-form 7.54.2 — MIT — Beier Luo
  - @hookform/resolvers 4.1.3 — MIT — Beier Luo

## 6. Fonts

6.1 PT Sans and Space Grotesk are used under the SIL Open Font License 1.1, self-hosted rather than loaded from a third-party font service — which is also why no font provider receives your IP address when you visit this site.

## 7. Getting The Licence Texts

7.1 The full text of every licence above is published by the respective project, and each is also available from the SPDX licence list at spdx.org/licenses.

7.2 If you need the licence texts as a single file — procurement and legal reviews often do — write to legal@lacspace.com and we will send them.

## 8. Corrections

8.1 **(important)** If you maintain a package listed here and the attribution is wrong, or a package of yours is used and is not listed, write to legal@lacspace.com. We will correct it and reissue this document with a new version.
