Is my text ever sent to a server?

No. After you install a language pack, translation runs in your own browser or app. There is no server mode to fall back to — not for a hard sentence, not for a rare language. The absence of that code path is the guarantee, not a policy promise.

Does it really work offline?

Yes, completely, once the language pack is installed. On a plane, behind a firewall, or with no signal, you get the same engine and the same quality as when you are online — because being online was never part of how it translates.

Why is the download about 1.5 GB?

A translation engine that never contacts a server has to carry the whole model with it. That is what an on-device engine actually weighs. Anything dramatically smaller is either translating web pages only or leaning on a server for the real work.

Do I have to install anything or create an account?

No account is needed to translate, and there is nothing to install beyond the one-time language pack, which downloads inside the browser you already have. A free account only matters if you want encrypted sync between your own devices.

What happens to my documents and PDFs?

They are opened, parsed, and translated entirely on your device. The file itself is never uploaded — there is no code path that could send it. This is the whole reason the tool exists for sensitive files like contracts and records.

If I cancel my subscription, do I lose translation?

No. A pack you have installed keeps working forever. Cancelling a paid plan loses you encrypted sync and the local API — never the ability to translate.

FAQ

Private translation: the questions people actually ask

The same handful of questions come up whenever someone weighs an on-device translator against the cloud service they already use. Here are straight answers — each one true of the product as it ships today.
