FEATHER — THIRD-PARTY NOTICES
Prepared 6 November 2026 for local review of version 1.0, build 1100.

Feather's own application is proprietary; its source code remains private.
The third-party components listed below retain their independent licenses.
The Feather terms do not remove or restrict those rights. Attribution
does not imply that these authors endorse Feather.

SCOPE
The locked Cargo graph for aarch64-apple-darwin resolves to 45 third-party
packages, including the patched IronCalc base and build-time/proc-macro crates.
All 45 have bundled, matching notices. This deliberately includes build-time
components rather than claiming that each has separately identifiable code
in the final optimized executable. The inventory was checked offline against
the frozen Cargo.lock and cached source manifests and license texts.

LICENSE PATHS
The full texts and copyright notices are in Third-Party-Licenses/ next to this
file. They are also preserved inside Feather Sheets.app at
Contents/Resources/ThirdPartyLicenses/. Carlito's full license is in
Third-Party-Licenses/Carlito/OFL-Carlito.txt and inside the app at
Contents/Resources/Fonts/OFL-Carlito.txt. The original authoritative license
texts are retained without translation or modification.

IronCalc base 0.9.1 comes from upstream commit
15ecfecb7cb9a50f7427911298d267023157fc45, with Feather modifications documented
in Third-Party-Licenses/ironcalc_base-0.9.1/FEATHER-PATCHES.md.
Copyrights and both upstream MIT/Apache license texts are retained. The MIT
option is used for this distribution; this does not change upstream licensing.

For alternative MIT/Apache/Unlicense/Zlib expressions below, this distribution
uses the MIT option. approx uses Apache-2.0; ryu uses BSL-1.0. unicode-ident
uses MIT AND Unicode-3.0 (the additional Unicode license is required and
included). All originally bundled alternative texts remain available.

RUST STANDARD LIBRARY
Rust 1.99.1 standard-library notices are retained verbatim from the exact build
toolchain under Third-Party-Licenses/Rust-standard-library/:
COPYRIGHT-library.html and licenses/. The Rust standard library is principally
MIT OR Apache-2.0, with component-specific exceptions and attributions in that
HTML document. This distribution uses permissive options where offered,
including MIT for the r-efi entries that also offer LGPL. The toolchain's
notice includes other targets and build dependencies as supplied upstream;
their inclusion does not assert that all are linked into this Mac app.
The compiler and Cargo are not distributed.

FONTS
Carlito Regular, Italic, Bold and Bold Italic are bundled under SIL OFL 1.1.
Copyright 2013 The Carlito Project Authors; Reserved Font Name: Carlito.
The supplied font bytes are unchanged from the audited build inputs. Carlito
retains its OFL license independently of Feather; fonts are not sold separately.
Microsoft fonts are not bundled. Locally installed fonts are not redistributed.

NOT BUNDLED
Python QA packages, test tools, source code, private workbooks, development
fixtures, marketing assets and toolchains are not in this download candidate.
Apple frameworks and system libraries are supplied by macOS, not copied here.
