What Can Websites See?
Run the test
Build a transparent inventory of network, browser, display, language, storage, preference, and capability information.
Start the test to generate current evidence. Nothing is pre-scored.
A result describes what this browser and this request exposed at the time of testing. It is not a certification of security or anonymity.
How to interpret it
These answers describe the tests boundaries before you rely on a result.
Can a normal website browse my local files?
No. A page can read a file only after you explicitly select or drop it into an allowed control.
Can it see precise location?
Precise browser geolocation normally requires a separate permission prompt.
Can this tool prove I am completely private?
No. It reports evidence visible to this browser and request. It does not certify anonymity, device security, identity, or every application route.
