ConnectKit — Commercial Software License Agreement
Copyright (c) 2026 Joo-Hwan Han ("Licensor"). All rights reserved.
ConnectKit is proprietary, commercial software. It is licensed, not sold.
IMPORTANT — READ CAREFULLY. This Commercial Software License Agreement (the
"Agreement") is a legal agreement between you (an individual or a single entity,
"Licensee") and Licensor for the ConnectKit software development kit, including
its libraries, binaries, and accompanying documentation (collectively, the
"Software"). By downloading, installing, copying, referencing, or otherwise using
the Software, Licensee agrees to be bound by this Agreement. If Licensee does not
agree, do not download, install, or use the Software.
1. DEFINITIONS
1.1 "Application" means a software product developed by Licensee that
incorporates the Software in object/compiled form as an integrated
component.
1.2 "Order" means a separate written or electronic ordering document,
subscription, or license agreement between Licensee and Licensor that
authorizes Licensee's use of the Software and sets out applicable fees,
scope, quantities, and term.
1.3 "Documentation" means the technical documentation Licensor makes available
for the Software.
2. LICENSE GRANT
Subject to Licensee's continued compliance with this Agreement and with a
valid, paid-up Order, Licensor grants Licensee a limited, non-exclusive,
non-transferable, non-sublicensable (except as in Section 3.2) license, during
the term of the applicable Order, to:
(a) install and use the Software to develop and test one or more Applications;
(b) incorporate the Software, in object/compiled form only, into Licensee's
Applications; and
(c) reproduce and distribute the Software solely as embedded within, and as
an integral part of, Licensee's Applications to Licensee's end users.
3. RESTRICTIONS
3.1 Except as expressly permitted in Section 2 or by mandatory applicable law,
Licensee shall not, and shall not permit any third party to:
(a) distribute, publish, sell, rent, lease, lend, host, or otherwise make
the Software available on a standalone basis or other than as embedded
within an Application;
(b) use the Software to build or offer a software development kit, library,
API service, or product that competes with the Software or replicates
its primary functionality for third parties;
(c) sublicense, resell, or transfer the Software except as embedded in an
Application and subject to end-user terms no less protective of
Licensor than this Agreement;
(d) modify, translate, or create derivative works of the Software, or
reverse engineer, decompile, or disassemble the Software, except to the
limited extent such restriction is prohibited by mandatory law;
(e) remove, alter, or obscure any proprietary notices, labels, or marks on
or in the Software or Documentation.
3.2 Licensee's end users receive no rights in the Software other than to use it
as embedded within, and necessary to the ordinary use of, the Application.
4. OWNERSHIP
The Software is licensed, not sold. Licensor and its licensors retain all
right, title, and interest in and to the Software, including all intellectual
property rights. No rights are granted except as expressly set out herein.
5. THIRD-PARTY AND OPEN-SOURCE COMPONENTS
The Software includes third-party open-source components that are provided
under their own license terms, including BouncyCastle.Cryptography (MIT
License). Nothing in this Agreement limits Licensee's rights under, or is
intended to override, those third-party licenses with respect to those
components. A list of such components and their licenses is available from
Licensor on request.
6. FEES
Use of the Software is conditioned on a valid Order and payment of all
applicable fees. Absent a valid Order, no license is granted under Section 2
and any use of the Software is unauthorized.
7. TERM AND TERMINATION
This Agreement is effective until terminated. It terminates automatically and
immediately if Licensee breaches any term, and also upon expiration or
termination of the applicable Order. Upon termination, Licensee shall cease all
use of the Software and destroy all copies in its possession or control.
Sections 3 through 10 survive termination. Termination does not, by itself,
revoke license rights already granted to end users for Applications lawfully
distributed before termination.
8. DISCLAIMER OF WARRANTIES
THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY
KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING BUT NOT LIMITED TO THE IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND
NON-INFRINGEMENT. LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL BE
ERROR-FREE, SECURE, OR UNINTERRUPTED.
9. LIMITATION OF LIABILITY
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL LICENSOR BE LIABLE FOR
ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR
ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATED TO
THIS AGREEMENT OR THE SOFTWARE, WHETHER IN CONTRACT, TORT, OR OTHERWISE, EVEN IF
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. LICENSOR'S TOTAL AGGREGATE LIABILITY
ARISING OUT OF OR RELATED TO THIS AGREEMENT WILL NOT EXCEED THE FEES PAID BY
LICENSEE FOR THE SOFTWARE UNDER THE APPLICABLE ORDER IN THE TWELVE (12) MONTHS
PRECEDING THE EVENT GIVING RISE TO THE CLAIM.
10. GENERAL

the entire agreement between the parties regarding the Software and
supersedes all prior or contemporaneous understandings on the subject.
10.3 Severability. If any provision is held unenforceable, the remaining
provisions remain in full force and effect.
10.4 No Waiver. Failure to enforce any provision is not a waiver of it.
