This WebAssembly(WASM) app hosted by Cloudflare pages (check Cloudflare privacy policy if you have concerns) and Github pages (check Github privacy policy if you have concerns) for free. It does not have its own server. The app itself does not require any network connection to generate the words. It is a static html page that use WASM compiled library to produce words.

To help users on the privacy concerns, it disables autocomplete functionality of html inputs and hides the sensitive information entry by using password input types.
