07 / GOOD TO KNOW
Good to know.
A few important things about downloads, connectivity, and what happens to your text.
Can I download it here now?
Yes. The Mac 0.1.0 beta is for Apple Silicon and is unsigned and not notarized. The Windows 0.2.0 installer is for x64. Installation and compatibility are still being validated; read the download notes and check the SHA-256.
Does translation require internet access?
Local glossary entries can provide some definitions. Full-sentence cloud translation needs a configured model service and an internet connection. Candidates depend on glossary, cache, and model settings.
Where does my text go?
When you use cloud translation, the text being translated is sent to your configured model service. The current Mac test build also includes translation-quality feedback that can be disabled in settings. We are refining the privacy explanation and defaults before release.
