The archive applies to every version of Readnslate that ships the library libreadnslate_bergamot.so with SHA-256 3d7d2ce562a9962ae74c1e6a1dc282a9f1e39607ee68e7741f7383ac2433e71b (36,362,792 bytes), which is the library in Readnslate 1.0.0. The app's own notices (Help & About › Licenses › Mozilla Bergamot Enhanced translation) point to this page.

What the archive contains

• The pinned upstream source. Mozilla's translations repository at revision eea6e5a80aa4ddd86d9cc35ce9a65b79aa3ab96d (release v0.6.0), exactly as GitHub publishes it, SHA-256 70e839dc9d62dedc173c7c1060e33920a6db65f748d833ab295823901149ab7d. The library is built from its inference/ tree.
• Readnslate's modifications. Unified diffs of the four build-metadata edits Readnslate makes to upstream files (Git lookups replaced by the pinned revision so the archive builds without Git), with the SHA-256 of each file before and after. No translation code is changed.
• Readnslate's adapter and build scripts. The small JNI bridge (bridge.cpp, CMakeLists.txt) and the scripts that fetch, adapt, build, verify and package the runtime, with the pinned manifests of every dependency and model.
• Licence and notices. The MPL-2.0 text and the notices file shipped inside the app, which lists every bundled component's licence.

The seven third-party dependencies the build also needs (ssplit-cpp, SentencePiece, onnxjs, ruy, cpuinfo, simd_utils and PCRE2 10.39) are not MPL-covered software, so the archive lists them with their repositories, revisions and SHA-256 checksums rather than bundling them; the included fetch script downloads and verifies them. The archive's README.md gives the rebuild steps (Android NDK 28.2.13676358, CMake 3.22.1, arm64-v8a).

Translation models

The Enhanced packs the app downloads are Mozilla's released translation models, also MPL-2.0, taken unmodified from Mozilla's model repository. The archive's models.json names each pack with its upstream revision and file hashes.

If the download does not work

Write to readnslate.supp@hotmail.com with "Source request" in the subject and the source will be provided at no more than the cost of distribution. This offer applies to every version of Readnslate that ships this engine.

Other open-source components

Readnslate also includes the Readium EPUB engine, Princeton WordNet, a rebuild of the AndroidX PDF viewer and other libraries under their own licences. Their notices are in the app and on the Licences page; those licences do not require a source offer. The AndroidX viewer is modified (a horizontal reading lock and the removal of its page-number bubble), and its notice says so.
