Privacy Policy

Last updated: April 9, 2026

Overview

NeuroTest AI ("we", "our", "us") is committed to protecting your privacy. This policy explains how our browser extension and web application handle your data.

Browser Extension — Data Collection

The NeuroTest AI browser extension collects the following data locally on your device only:

Website hostnames you visit (e.g., "youtube.com" — not full URLs or page content)
Time spent on each website
Number of visits per website
Session duration

When Data Leaves Your Device

Your browsing data is sent to our servers only when you explicitly click "Analyze Brain Effects" in the extension popup. When this happens:

A summary of website hostnames and time spent is sent to our API
The data is processed by AI to generate your neural analysis
The analysis result is returned to your browser
No browsing data is stored on our servers — it is processed in memory and immediately discarded

Web Application — Data Collection

When you use the NeuroTest AI web application (neurotest.live), files you upload for analysis (images, audio, video, text) are:

Sent to our AI providers (Groq, Cerebras) for analysis
Processed in memory only — never stored on our servers or any third-party servers
Not used for AI model training

What We Do NOT Collect

Full page URLs or URL parameters
Page content, form data, or passwords
Personal identification information
Cookies or authentication tokens
Keystrokes or screen captures
Browsing history beyond the current session

Data Storage

All browsing tracking data is stored locally using Chrome's chrome.storage.local API. This data never leaves your device unless you explicitly request an analysis. You can reset all stored data at any time using the "Reset Session" button in the extension.

Server-Side Data Retention

When you click "Analyze Brain Effects", the following data is sent to our server at neurotest.live:

Website hostnames (e.g., "youtube.com") and time spent per site
Visit counts per site
Session duration and site categories

Retention policy: This data is processed in server memory only for the duration of the AI analysis request (typically 10–30 seconds). It is never written to a database, file system, or any persistent storage. Once the analysis response is returned to your browser, the data is discarded from server memory. We retain no record of your browsing activity.

Host Permission

The extension requests access to https://neurotest.live/* solely to send your browsing summary to our analysis API when you click "Analyze Brain Effects". No other external domains are contacted.

Third-Party Services

When you request an analysis, your data is processed by:

Groq — AI inference provider (processes analysis prompts)
Cerebras — AI inference provider (fallback)

These providers process data in memory for inference only and do not store your data.

Permissions Explained

tabs

Track which site is currently active to measure time spent per site. Only the hostname is read — not full URLs, page content, or query parameters.

storage

Store browsing session data locally on your device using chrome.storage.local.

alarms

Periodically save time tracking data (every 1 minute) to prevent data loss if the browser closes.

Your Rights

You can reset all tracked data at any time via the extension
You can uninstall the extension at any time to stop all tracking
You can use the web app without installing the extension
No account or sign-up is required
