## RIME-LMDG / Wanxiang grammar data

  exact upstream release digest in their manifest. They are not bundled by default.

Sogou hotword data is never redistributed by this project. The local dictionary
importer accepts files selected by the user and stores them only in app-private
storage.

## Document import
