Software License

1.0 / 2026-10-21

Distinguish SparkleRight’s own software, future store copies, and separately licensed components.

1. Proprietary software

© 2026 Sparkle. All Rights Reserved. Except where separately authorized, rights in SparkleRight’s own code, interface, icons, brand, and documents are reserved. Component open-source licenses do not make the whole product open source. No public copy is distributed yet; this statement is not permission to download, redistribute, or publish it.

2. Future store and test copies

Copies actually distributed through the Mac App Store use Apple’s Standard EULA and store rules unless an effective custom EULA is provided. Before that release, this page is not a claim of availability, submission readiness, or approval.

Non-store development or test copies are limited to purposes and scope expressly permitted by the rights holder. Without separate permission, do not resell, sublicense, publicly distribute, or use Sparkle branding to imply a partnership. These general restrictions do not exclude uses, modifications, or other rights expressly permitted by applicable law or component licenses.

3. Independent component licenses

WebP 1.6.0 is statically linked in the current app and uses its BSD-style three-clause license and accompanying patent grant. Original copyright, conditions, disclaimer, and patent grant are retained and downloadable. Those original texts govern component rights and obligations.

ZIP uses the public macOS libarchive interface. System frameworks and components are supplied by macOS; their use grants no Apple or other trademark, endorsement, or branding rights.

4. Your content and retained rights

Existing rights in user files, imported templates, and generated material remain with their lawful owners. This software license grants no rights to third-party content. Unspecified rights are reserved without excluding rights required by law. Contact sparklebossletter@outlook.com for licensing questions.
