Technical explanation

Values come from the User-Agent Client Hints API where available, with a parsed navigator.userAgent fallback. User-agent strings can be reduced or spoofed, so browser and operating-system labels are best-effort.

Screen, language, timezone, and feature checks describe the browser environment, not the physical device model. A browser cannot reliably reveal exact hardware identifiers.

Troubleshooting

Browser version looks wrong

Privacy tools and user-agent reduction can make version detection imprecise.

Timezone is unexpected

The browser follows the operating-system timezone setting.

Download does not start

Allow downloads for this site or copy the report instead.

Feature shows unsupported

The browser may require HTTPS, a permission, or a newer version.
