Hushfox runs language models entirely on your phone. Nothing you type leaves the device: there is no server that could receive it, no account to create, and no cloud to sync to. Download any GGUF model from Hugging Face and start chatting. You need a connection once, to fetch the model. After that it works fully offline, on a plane, on the subway, or anywhere with no signal. Private by design Your prompts and answers stay on the device. Hushfox has no analytics SDK and no hidden network calls. A built-in log shows you exactly what, if anything, leaves your phone. Any open model Bring any GGUF from Hugging Face. On iPhone and iPad you can also run MLX models. The only real limit is your device RAM: in practice, 3B to 8B models quantized to 4 bits run on a modern phone. Long conversations that stay put Pick up a long chat instantly. Context is kept on device, so a conversation you started days ago is right where you left it. Yours to control No subscription wall to open the app. No sign-in. No tracking.
