Privacy
Your notes are files on your disk. Nothing leaves unless you ask.
Neuron has no account, no sign-in and no telemetry. It does not collect analytics, usage statistics or crash reports. This page says exactly what the app can send anywhere, what triggers it, and how to stop it.

What Neuron collects about you
Nothing. The developer of Neuron receives no personal information from the application. There is no account system, no registration, no licence check, no analytics endpoint and no crash reporting service. No data is sold, shared or used for advertising, because none is received in the first place.
Your workspace — notes, databases, canvases, views, attachments and settings — stays in the folder you chose and in the application's local data directory on your own device. Neuron does not upload it anywhere.
What can leave your device, and when
Four things in Neuron can reach the network. Each is listed with what it sends and what causes it. Nothing here routes through the developer's servers; there are none.
| Feature | What is sent, and to whom | When |
|---|---|---|
| AI assistant | The text you submit — which may include note content, filenames and anything else you place in the prompt — plus your API key, sent directly to the provider you configured: Anthropic, OpenAI, Google, OpenRouter, or any OpenAI-compatible endpoint you name (including a local one such as Ollama, which leaves your machine only if you point it off-device). | Off by default. Only after you enable a provider, supply your own key, and send a message. |
| Update check | A request to GitHub for the latest release metadata. GitHub receives your IP address and user agent, as any web request would. No workspace content is included. | On launch, for installer builds. Not in the Microsoft Store build, which updates through the Store instead. |
| Browser tabs | Ordinary web browsing. The sites you visit receive whatever they normally would. Browsing data is stored in an isolated local session partition. | Only for pages you open yourself. |
| Plugins |
A plugin can request an arbitrary http(s) address
through the app. What it sends is determined by that plugin, not
by Neuron.
|
Only for plugins you install and enable. See the section below. |
Third-party services have their own terms. When you use an AI provider, your prompt is governed by that provider's privacy policy and data-retention practices, not by this one. Some providers retain prompts, and some use them for model training unless you opt out. Read the policy of whichever provider you configure before sending anything you would not want retained.
Your API keys
Keys you enter are stored on your device, in the application's local settings, and are used only to authenticate to the provider you gave them for. They are held by the app's main process and are deliberately unreadable from the note-rendering layer, so note content and plugins cannot read them. They are never sent to the developer.
You can remove a key at any time in Settings. Revoking it with the provider is the stronger step, and one only you can take.
Custom views and plugins
Neuron runs HTML views and folder mini-apps from your workspace in an isolated process with no access to Node, and each one is limited to the file paths its manifest declares. You approve that list, and Neuron shows you which paths a view may read and change, before it runs. Views cannot reach the network at all: their content policy permits requests only to Neuron's own local API.
Installed plugins are a different matter. A plugin can ask Neuron to make an arbitrary web request. Install plugins only from sources you trust, exactly as you would a browser extension.
Importing browser cookies
Neuron can copy cookies from your local Chrome profile into its own browser session, so that sites you are already signed into stay signed in inside the app. This is a Windows-only feature and it happens only when you explicitly ask for it.
Cookies are read from your own Chrome installation on your own machine and written into Neuron's local session storage. They are not transmitted anywhere, and the developer never receives them. Cookies are credentials: use this only on a device you control.
Local data Neuron keeps
- Your workspace — plain files in the folder you chose. Delete the folder and they are gone.
- Settings and API keys — in the application's local data directory.
- Version history — a journal of a file's previous contents, captured before an overwrite so you can recover from a mistake. Stored locally, keyed to the workspace, and safe to delete.
- Browser session data — cookies and storage for the built-in browser tabs, in an isolated local partition.
All of it lives on your device. Uninstalling the application, or deleting its data directory, removes everything except the workspace folder you chose — which is yours, and which Neuron leaves alone.
Children
Neuron is a general-purpose writing tool and is not directed at children. It collects no information from anyone, including children.
Your rights
Rights of access, correction, deletion and portability normally require asking an operator for a copy of your data. Here there is nothing to ask for: no personal information is transmitted to or held by the developer. Your data is in files you already have, in formats — Markdown, JSON — that other software can read.
For data held by an AI provider you have used, contact that provider directly; only they hold it.
This website
These pages are hosted on GitHub Pages, which logs requests including IP addresses under GitHub's privacy statement. The site itself sets no cookies, runs no analytics and loads no third-party resources — fonts included. The downloads list is fetched from GitHub's public API when you open the page.
