This page explains what data Cognitive Train (“we”, “us”) collects, how we use it, and the choices you have.

Quick summary

No account required. You can use our apps without signing up.
Results saved locally by default. Scores and settings are stored in your browser (local storage) and do not leave your device unless you export or share them.
Minimal technical data. Like most sites, we may receive basic device/usage info for performance, security, and analytics.
Easy opt-out. Clear local data anytime in your browser or via in-app reset buttons.

Data we collect

Information you provide: We do not require an account to use the core apps. If you contact us by any means, we receive the information you include in that message.

Information collected automatically: basic device data (browser type, language, approximate location from IP, screen size), usage events (pages viewed, time on page, referrer), and diagnostic logs for performance and security.

How we use data

To run and improve our apps (performance, usability, accessibility).
To fix bugs and protect against abuse and fraud.
To understand overall usage patterns and plan new features.

App results & local storage

Our apps may store results, settings, or progress in your browser using local storage. This stays on your device and is not sent to our servers by default.

Clear anytime: use your browser’s “Clear browsing data” or in-app “Reset/Clear data”.
Sync/export (optional): if provided, data leaves your device only when you use those features.

Cookies & analytics

We aim to keep cookies to a minimum. If analytics is enabled, it may use cookies or similar technologies to measure aggregate traffic and usage. Where required by law, a consent banner will be shown.

Provider: Google Analytics 4 or a comparable privacy-focused tool (if enabled).
Purpose: aggregated metrics; we do not build personal profiles.
Controls: opt out via our banner (where shown) or your browser’s tracking protection.

Sharing & third parties

We do not sell your personal information. We may share limited data with service providers who help operate the site (e.g., hosting/CDN, analytics) under confidentiality obligations.

Retention

We keep server logs and analytics records only as long as needed to operate and secure the service. Local storage on your device remains until you clear it.
