What happens here?
This page can read technical information directly from your browser and show it to you, for example:
- Public IPv4/IPv6 address (queried from an external service)
- Browser and operating system identification (Windows, Android, Linux, macOS, iOS)
- Screen resolution, available screen area, and orientation
- Language setting and timezone
- Referring page, if provided by your browser
- Whether cookies, touch input, and local storage are available
- Number of CPU cores and, if supported by your browser, approximate memory
- Estimated connection type and other technical traits (e.g. PDF viewer, automated control)
- Speech synthesis voices, physical keyboard layout, sensor and gamepad availability
- Response time to our own server (same as any normal page load)
All values are read and shown to you locally in your browser, without us storing them. One exception: for the IP address, your browser queries the external service ipify.org directly – your IP address is transmitted to this provider, but not routed through our server and not stored by us. Three particularly revealing checks (installed fonts, audio fingerprint, local network IP via WebRTC) are only read after additional confirmation directly within their tile – these also stay fully local.
Your System Information
Info about this data
This information can, in principle, be read by almost any website – usually automatically in the background via JavaScript as soon as the page loads, with no notice and without you having to confirm anything. This page deliberately asks first; on the web, that is the exception rather than the rule. In combination, this data forms a so-called browser fingerprint, which may allow a device to be recognized again – even if its IP address changes or cookies are deleted. Alpha10 does not store or transmit these values; they are shown here in your browser only. The one exception is the IP tile above: for that, your browser queries ipify.org directly, which transmits your IP address to this external provider.
This data was only read locally in your browser and was never stored anywhere. Reload the page to remove it again.
