SparkleScroll Software License

1.0 / 2026-10-19

Permissions for original software and Apache-2.0 portions apply separately; a new interface or name does not remove upstream rights.

1. Original work and scope

Rights in SparkleScroll’s name, independent icon, interface, and new code remain with their respective holders. Sparkle is maintained by 唐梓耀 / AdrianSparkle and 丁铭 / EliasSparkle. No third-party trademark or system-interface rights are transferred.

2. Use and store copies

Subject to the Terms of Service, you may install and use a lawfully obtained version on compatible Macs you own or are authorized to use. For App Store copies without a separate custom EULA, Apple’s standard EULA and applicable store rules apply alongside relevant conditions. There is currently no public website download.

3. Reserved proprietary rights

Except as permitted by law, separate express permission, or independent component licenses, no right is granted to redistribute original proprietary software, modify it for separate sale, rent or sublicense it, or remove rights notices. This does not restrict non-excludable statutory rights, security research, or Apache-2.0 permissions for covered portions.

4. Apache-2.0 origin and priority

Scroll-transformation logic is adapted from Scroll Reverser 1.9 by Nicholas Moore, fixed upstream commit 7bc618d4436425c59c630cbd2956e6f4ae46ebe0. The product uses a Swift implementation, a Sparkle interface, and public APIs. Original Apache-2.0 text and the preserved NOTICE are provided separately.

Covered portions may be used, modified, and distributed under Apache-2.0, subject to applicable license, change-marking, copyright, and NOTICE requirements. This page does not declare the entire application open source, and proprietary reservations do not override independent component permissions.

5. Trademarks, updates, and responsibility

Upstream restrictions concerning the Scroll Reverser name and icon remain; source availability does not grant a right to use them as derivative-product branding. SparkleScroll uses an independent name and icon. Later versions follow the terms actually supplied. Responsibility and statutory rights follow the Terms of Service and applicable law.

6. Licensing contact

Contact sparklebossletter@outlook.com about team distribution, commercial cooperation, or original-source licensing and explain the intended scope. Separate commercial arrangements do not remove existing Apache-2.0 permissions for covered portions.
