# Silo Apple App Store / DRM Exception

Copyright (C) 2026 Silo Media L.L.C. and contributors

Silo Apple is licensed under the GNU Affero General Public License,
version 3 or (at your option) any later version — see [LICENSE](LICENSE) —
with the following additional permission.

## Additional permission under AGPL v3 section 7

As an additional permission under section 7 of the GNU Affero General
Public License v3 (incorporated by section 7 of any later version the
recipient elects), the copyright holders grant permission to distribute,
install, and use this Program — and any modified versions thereof —
through application stores and beta-distribution platforms operated by
third parties (including but not limited to the Apple App Store and
Apple TestFlight), even where the platform's terms impose restrictions
on:

- signing or re-signing of the binary by anyone other than the original
  developer or the platform operator;
- tamper protection, FairPlay-style DRM, or similar integrity controls
  applied to the binary by the platform;
- end-user redistribution of the installed binary outside the platform's
  own channels;
- end-user re-linking of the installed binary against modified versions
  of the Program,

even where such restrictions would otherwise be incompatible with
sections 4 through 6 of AGPL v3.

This permission applies solely to the binary distribution path. It does
not waive any obligation under the License regarding source code: the
complete corresponding source for the Program, including any
modifications, remains available under AGPL v3, and recipients retain
every right that license grants with respect to that source — they may
obtain it, study it, modify it, build their own copy, and distribute
their modified version under the same license, outside the constraints
of any application store.

As provided by section 7 of AGPL v3, any recipient redistributing the
Program may remove this additional permission from their copy.
