Your signature stays in this browser and is not saved by this tool. It cannot tell us who you are or how unique your browser is.
What can a website learn?
Browser fingerprinting combines details such as graphics rendering, screen size and language into a comparison signature. Unlike a cookie, these details can be read without saving a tracking identifier in your browser.
Run this test before and after changing a privacy setting to see which values are readable. The signature helps compare those observations; it does not measure how unique your browser is among other users.
Device details
Screen size, CPU thread count and approximate memory can help distinguish devices. Many devices share these values.
Language and location settings
Your language and timezone are readable browser settings. They do not establish your physical location.
What to do next
Review your browser’s built-in privacy controls, then check again. A changed signature does not measure improved privacy.

Common questions
Does the signature identify me?
No. It summarizes a set of browser properties. Many browsers may share them, and this tool does not compare you with other users.
Is anything stored?
This tool calculates the signature locally and does not save it. Storage availability is checked with a temporary entry that is removed immediately.
Why does it change?
Browser updates, display changes and privacy protections can change or randomize the exposed signals.
Does “limited access” mean I cannot be tracked?
No. Blocking some APIs reduces what this test can read. Other techniques and account activity can still reveal information.
