PrivacyLLM - On device AI

PrivacyLLM is a complete AI assistant that runs entirely on your iPhone. No cloud. No accounts. No tracking. Your conversations, your documents, and the model's reasoning never leave your device — because there's no server for them to go to.

Most AI apps send everything you type to someone else's computers. PrivacyLLM is built on the opposite idea: a genuinely capable assistant can live in your pocket, with your data staying yours.

PRIVATE BY DESIGN
• The language model runs on your device's GPU. Your prompts are never sent to a cloud AI provider.
• Nothing to breach: we run no servers and store none of your data. There is no database of your conversations to be hacked, leaked, or subpoenaed — it doesn't exist.
• Works fully offline. Apart from optional web search, every feature works in airplane mode.
• No analytics, no ads, no telemetry of any kind. Our App Privacy label says it plainly: Data Not Collected.

WHAT IT DOES
• Chat with a fast, modern assistant — replies stream in token by token, with full Markdown and syntax-highlighted code.
• Fast and Thinking modes: switch between a quick model and a more deliberate one that shows its reasoning before it answers.
• Gets things done: add a calendar event, set a reminder, or start a call or text, just by asking. Off by default, and iOS confirms before anything is dialled or sent.
• Remembers you: a few short facts, used in every chat, visible and deletable in Settings.
• Chat with your PDFs: import a document and ask questions about it. The text is extracted and indexed on-device, and the answer tells you which section it came from.
• Voice Memos & podcasts: turn any text, a PDF, or a whole conversation into audio and listen on-device, with playback that resumes where you left off.
• Optional web search: when you turn it on, only short keyword queries go to a privacy-respecting search engine (DuckDuckGo by default) — never your conversation. Search is OFF by default.
• Voice input: dictate messages using Apple's on-device speech recognition. No audio ever leaves your phone.
• Search every chat, clear a chat's context without losing it, and see your context and token usage any time.

YOU'RE IN CONTROL
• Choose your model and download it once, directly to your device. The list stays current, and you can bring your own.
• Lock the app behind Face ID. Add a home screen widget for one tap in.
• Everything is stored locally and encrypted, readable only on your iPhone.
• Open and inspectable — you don't have to take our word for any of this.

PrivacyLLM is free, with no ads and no subscriptions.

Your AI assistant belongs where your data does: on your device, in your hands.

REQUIREMENTS
A recent iPhone with enough memory is recommended for the larger models. A network connection is needed only for the one-time model download and for optional web search.
