Your screen, your keys, your PC.
Last updated: 10 November 2026 · applies to the Izuki app for Windows, its phone and TV companions, and this website.
Izuki is a free, open-source assistant made by Solomon Nwachukwu (“we”, “us”). This page says plainly what Izuki keeps, what it sends and to whom, and how you stay in control. Because Izuki is open source, you can check every line of it on GitHub.
The short version
- No Izuki account, no ads, no analytics. We don't receive your screen, your voice, your chats or your keys.
- Your requests go to the AI service you pick, with your own key: a screenshot only when the task needs your screen.
- Hearing your voice happens on your PC unless you switch on Sharper hearing.
- Everything Izuki remembers is on your PC, where you can see it and delete it.
- Extras send data only once you turn them on: linked apps, your phone, your TV, cloud voices.
What stays on your PC
Izuki keeps its data in your Windows user folder, at %APPDATA%\Izuki, and in the app's own storage. None of it is uploaded to us.
| What | Why it's kept |
|---|---|
Settings and AI keys (settings.json) | So Izuki can talk to the AI and apps you set up. Keys are stored as plain text in your user folder, so anyone who can sign in to your Windows account could read them; see keeping your keys safe. |
Memories (memories.json) | Things you asked Izuki to remember. Listed in Settings, where you can delete any of them or all of them. Izuki never saves passwords, keys or card numbers as memories, and never saves test answers. |
| Chats, notes, reminders, study logs | Your history, so you can search it and pick it up again. |
Logs (logs\izuki.log) | To diagnose problems. Keys, emails, phone numbers and your Windows user name are scrubbed from error reports. |
Missed wake-word clips (debug\) | When “Hey Nova” isn't recognised, the last few short clips (a dozen at most) are kept to help improve recognition. They never leave your PC. |
What Izuki did (actions\) | A list of what Izuki did or changed on your PC (clicks, apps opened, looks and tweaks, files cleared, messages sent), so you can always check. Kept for two weeks. It never holds what was typed into a box, only how much. Turn it off or clear it in Settings → Privacy. |
Saved window layouts and undo (layouts.json, looks.json, tweak-packs-undo.json) | Where your windows go for a saved layout, and how Windows was before a look or tweak pack, so Undo can put it back exactly. |
| Screenshots for a request | Taken when a request needs your screen, held in memory for that request, and not saved to disk. |
What leaves your PC, and where it goes
To the AI service you choose
Izuki doesn't have an AI of its own: you connect one with your own key (for example Google Gemini, Groq, NVIDIA, OpenRouter, Mistral or Anthropic), or run one on your PC with Ollama. When you ask something, Izuki sends that service:
- what you asked, and the recent turns of the conversation;
- a screenshot, only when the request needs your screen (plain conversation sends text only), with the names of the buttons and fields on screen;
- memories that matter to the request, and files or pictures you attached.
That service's own privacy policy and terms apply to what it receives. Free tiers often let the provider keep or use what you send (Google's free Gemini API uses it to improve Google's products, and NVIDIA's free trial says requests may be logged), so don't keep anything on screen you wouldn't want them to see while you ask. A model on your PC through Ollama keeps everything local.
Hearing and speaking
- The wake word and speech-to-text run on your PC. With Sharper hearing on, what you say to Izuki is also sent to your Gemini or Groq key to transcribe. You can switch it off in Talk settings.
- The default natural voice runs on your PC. If you pick a cloud voice (Gemini, Groq, Azure or ElevenLabs), the text being spoken goes to that service.
The web
When you ask Izuki to search or read a page, your search words go to search services (such as Google through your Gemini key, Brave, Wikipedia, DuckDuckGo or Bing), and pages are fetched directly from the sites, like a browser would.
Updates and downloads
Izuki asks GitHub for its newest version and downloads updates from GitHub. On-device speech and voice models are downloaded once from Hugging Face, from a fixed list of sources, and then run on your PC.
Extras that send data only once you turn them on
- Your apps (Gmail, Calendar, Slack and others): linked through Composio with your own Composio key. Izuki reads what a request needs, and asks before it sends, posts or deletes anything.
- Your phone and TV: linking one copies your AI settings, keys and memories to that device so it works on its own. Call Izuki opens a temporary Cloudflare “quick tunnel” (encrypted https, behind a long secret link) so your phone can reach your PC; your phone's own speech recognition, which may be run by its maker (Google or Apple), hears you on that page.
- Discord and Telegram: messages go through the bot you set up, to your PC.
- Lecture and call notes: after you say yes, short pieces of the audio go to the speech-to-text service you have a key for (Groq's Whisper, or Gemini) to be written down. Only the words are kept, never the audio.
- The browser extension: see its own extension privacy policy.
What we receive
Nothing, automatically. There's no account, no analytics and no telemetry. Izuki can send error reports with keys, emails, phone numbers and your user name removed, but no report destination is switched on, so reports stay in your logs folder. If that ever changes, this page will say so first, and you can turn reports off in Settings → Something wrong?.
We only see what you choose to send us: an email to izuki.hq@gmail.com, or an issue you open on GitHub (which is public).
We don't sell or share personal data, because we don't collect it.
This website
This site has no analytics, no ads and no tracking cookies. Like any website, it loads some things from other services, which see your IP address when they do: fonts from Google Fonts, the Earth photo from Unsplash, and release notes from GitHub. Your browser may remember small preferences in its own storage; that never leaves your browser. The site is hosted on GitHub Pages.
Your controls
- See and delete memories in Settings, one at a time or all at once. Say “forget …” to remove one.
- Delete chats one by one, or all at once from Recent chats.
- Remove a key by clearing it in Settings, and revoke it on the provider's site if you think it leaked.
- Unlink apps, your phone or your TV in Settings at any time.
- Turn off error reports in Settings → Something wrong?.
- See what Izuki can reach in Settings → Privacy → What Izuki can access: the microphone, the screen, the camera, your phone, linked accounts and saved keys, each with its switch.
- See everything it did in Settings → Privacy → What Izuki did, or clear that list.
- Take a copy of your data: Settings → Privacy → Your data saves everything Izuki keeps about you in one .zip in your Downloads, with your keys and passwords left out.
- Erase everything: Settings → Privacy → Your data. Izuki closes, starts again and erases its data before loading anything. Kept: downloaded AI models and tools, and what lets you undo changes to Windows. Code mode's working copies of your projects are removed too, the same careful way Code mode does it; your real projects aren't touched. You can choose to keep your keys.
- Remove Izuki completely: erase everything as above, then uninstall it.
Children
Izuki isn't made for children under 13. The AI services you connect have their own age rules, often 13 or older, and 18 or older for some.
Changes and contact
If Izuki starts handling data differently, we'll update this page and its date before that version ships, and say so in the release notes. Questions or requests: izuki.hq@gmail.com.
