Incognito Fingerprint Tracker
This demo reveals how your browser can be uniquely identified even in Incognito/Private mode, without using traditional cookies. Your "Stable Fingerprint ID" below is generated from core browser settings.

How it Works (Simplified)
We collect various pieces of information your browser readily provides. For the 'Stable Fingerprint ID', we use a subset of these that are less likely to change between normal and private browsing sessions on the same browser:
- User Agent String
- Browser Language(s)
- Screen Resolution & Color Depth
- Timezone
- Installed Fonts (list of common fonts checked)
- WebGL Renderer & Vendor
- Platform (OS)
- Hardware Concurrency
- (Other attributes like Canvas, Audio, Plugins, DoNotTrack are also collected and used for the detailed similarity score below, but not for the primary Stable ID because they can be more volatile or differ in Incognito mode.)
The Stable ID helps demonstrate re-identification. The full attribute comparison shows the nuances.
