Keysat Source-Available License 1.0 SPDX-Short-Identifier: LicenseRef-Keysat-1.0 Copyright (c) 2026 Keysat The terms below govern Your rights to access and use this software. By using the software in any way, You accept these terms in full. 1. DEFINITIONS "the Software" means this source code distribution and any binaries built from it, in whole or in part, including any Modifications. "You" means the individual or legal entity exercising rights under this license. "Internal Use" means use of the Software by You, Your employees, or Your contractors acting on Your behalf, including operating the Software on infrastructure deployed by You (including rented compute such as VPS or cloud instances You control) to support Your own products and operations. "Modifications" means any changes, additions, deletions, or derivative works that You make to the Software's source code. "Managed Service" means hosting the Software, or any substantial portion of its functionality, in a manner that allows third parties (other than Your employees or contractors acting on Your behalf) to use it through a network interface, or to take advantage of its functionality as a service or product offered to them. Your own customers receiving signed license keys from an instance of the Software You operate are NOT a Managed Service under this definition — that is the intended use case. 2. GRANT OF RIGHTS Subject to the restrictions in Section 3, the copyright holder grants You a non-exclusive, worldwide, royalty-free license to: (a) view, study, and audit the source code of the Software; (b) compile, install, and run the Software for Internal Use, including operating an instance as Your private licensing service to issue signed license keys for software products You sell or distribute; (c) make Modifications to the Software for the purposes of (a) and (b), provided that Modifications remain subject to this license. 3. RESTRICTIONS You may NOT, without prior written permission from the copyright holder: (a) distribute compiled binaries of the Software, or any derivative works in compiled form, to third parties, whether free of charge or for a fee; (b) provide the Software, or any substantial portion of its functionality, as a Managed Service; (c) sell, sublicense, lease, rent, or otherwise commercialize the Software itself (as distinguished from selling licenses to Your own software products through an instance of the Software You operate, which is expressly permitted under Section 2(b)); (d) remove, alter, or obscure any copyright notices, license text, attribution lines, or this license file embedded in or accompanying the Software. Public source-code forks (for example, on GitHub) are permitted provided that the fork carries this license unchanged and does not enable, facilitate, or attempt to circumvent any of the prohibitions above. 4. CONTRIBUTIONS By submitting any contribution to the upstream project (code, documentation, designs, or other materials), You grant the copyright holder a perpetual, worldwide, non-exclusive, royalty-free, irrevocable license to use, reproduce, modify, relicense, distribute, and incorporate Your contribution as part of the Software or any future version of it, under the terms of this license or any later license the copyright holder adopts. You retain ownership of Your contribution; this Section grants a license-back, not an assignment of copyright. 5. NO WARRANTY THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT, OR OTHERWISE, ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOFTWARE OR ITS USE OR OTHER DEALINGS IN THE SOFTWARE. 6. TERMINATION This license, and all rights granted to You under it, terminate automatically upon any breach of its terms. Upon termination, You must immediately cease all use of the Software and destroy or permanently delete all copies in Your possession or control. Sections 4 (Contributions), 5 (No Warranty), and 6 (Termination) survive any termination. 7. ENTIRE AGREEMENT This license constitutes the entire agreement between You and the copyright holder regarding the Software and supersedes any prior agreements, oral or written. No modification of this license is effective unless made in writing and signed by the copyright holder.
