Privacy policy

This page covers two things: the AI Mascot app, and this website (nemuistudios.com). Both are made by Nemui Studios.

The short version

AI Mascot has no account, no server of ours, no analytics, no crash reporter and no ads.
The app makes only two kinds of network calls of its own: license checks with Lemon Squeezy, and a version lookup for AI updates, which you can turn off.
Everything else the app does stays on your computer. It never writes your prompts or the AI’s replies to disk.
The AI tools you connect (Claude Code, Antigravity and Codex) talk to their makers’ servers. That’s their own behavior, under their makers’ policies.
This website uses no cookies.

What the app sends over the internet

License checks, with Lemon Squeezy

Lemon Squeezy runs our store and the license keys. The app talks to it only in these cases:

When you enter a key you bought. The app sends the key and your computer’s name. Lemon Squeezy shows that name in the list of computers using the key.
When it re-checks a bought key. This happens about once every 7 days, or when you press “Check now”. The app sends the key and an ID that Lemon Squeezy gave it when you first entered the key.
When you remove a key from a computer, or swap it for another one. The app sends the key and that ID, so the spot is freed up.

Like any website, Lemon Squeezy also sees your IP address. Its reply includes the email address you bought with. The app keeps that email on your computer, to show who the key is licensed to.

The free trial makes no network call. Gift keys are checked on your computer and make no network call either.

Lemon Squeezy’s own terms and privacy policy cover what it keeps.

AI update checks

To tell you when an AI tool has an update, the app looks up the latest version number. It does this once a day, and only for the AIs you have installed and connected. Each lookup goes to that tool’s public release address:

Claude Code: Anthropic’s download server
Antigravity: Google’s update server
Codex: the npm package registry

The request carries nothing about you or your sessions, and no ID. The server sees your IP address, like with any web request. You can turn this off in Settings, under Connections, with Check for AI updates. The app never downloads or installs an update by itself. When you click Update, it does one version lookup for that AI, even with the checks turned off, then runs that AI tool’s own update command.

Things you start yourself

These only happen when you click them:

Install Claude Code downloads Anthropic’s installer. The setup guide shows you the command first.
Sign in to Claude runs Anthropic’s own sign-in, which may open your browser.
Buy opens the store’s checkout page in your browser.
Help links in the setup guide open the AI tools’ own help pages in your browser.
Links in an AI’s reply open in your browser, never inside the app.

Nothing else in the app connects to the internet. The small helper program that the AI tools run (the “hook”) has no network code at all. It talks to the app through private connections that stay on your computer.

What the app keeps on your computer

All of this stays on your computer. None of it is sent anywhere, apart from the license key and its ID described above.

Your settings: dock position and size, sounds, colors, hotkeys, mascot names and personality, which AIs you connected, and your last 5 session folders.
Your license: the date your trial started, and if you entered a key: the key, Lemon Squeezy’s ID for this computer, who it’s licensed to (the gift name or your purchase email), and when it was last checked.
A second copy of the trial start date, kept in the system’s normal settings store (the app’s preferences on a Mac, the registry on Windows). It’s there so deleting the app’s data doesn’t restart the trial.
Hidden sessions you can continue: the folder, the AI’s session ID and the AI’s name. At most 20, and each is dropped after 30 days.
Technical logs, for fixing bugs: start and quit times, event names, tool names (like “Bash”), the last part of a session folder’s name (like “my-project”), and the name of the app in front when you switch desktops. Never your prompts, the replies, the commands or the contents of your files.
The Claude Code installer’s output, only if you used Install Claude Code, so the app can show why an install failed.
Your logo, only if you upload one for the “My logo” mascot.

The text in the speech box, the history of a hidden session and the AI’s last reply are kept in memory only. They’re gone when the app quits.

Voice typing

On a Mac, the 🎤 button turns your words into text on the Mac itself. The microphone is on only while you dictate, and macOS shows its orange dot while it’s on. AI Mascot never saves or sends the audio, and never logs what you said. If your Mac can’t recognize your language without the internet, nothing is recorded and the box tells you so.

On Windows, the 🎤 button opens Windows’ own voice typing. Windows does the listening, under its own speech settings.

What the app changes in your AI tools

When you connect an AI, the app adds a few things to that AI tool’s own files:

hook entries in its settings, so the tool tells the mascot what’s happening
a short, marked section in its instructions file (CLAUDE.md, GEMINI.md or AGENTS.md) that carries your mascot’s name and personality and asks the AI to end replies with a mood tag

It backs up each file before the first change. Disconnect in Settings removes these again. Settings → About → Remove everything… removes them for every AI, deletes the app’s data and quits. It leaves the second copy of the trial date in place.

What the hook sees

Your AI tool starts the hook each time something happens in a session. The tool hands it the event, which can include your prompt and what the AI is about to do. The hook passes on only a small summary to the app on your computer: the event’s name, the session, the folder, the tool’s name, a short detail (like a command or a file path), and the AI’s last reply. It doesn’t pass on your prompts or the contents of your files.

Your AI tools

Claude Code (made by Anthropic), Antigravity (Google) and Codex (OpenAI) are your own programs, signed in with your own accounts. They send your prompts, the files they read and the results of what they do to their makers’ servers, and keep their own history. Their makers’ terms and privacy policies cover that, not this one. AI Mascot never sees or stores your AI account passwords or sign-ins.
