Privacy
This site exists to show you what any website can learn about your browser. Here is exactly what it keeps.
What is collected
When you open the scanner, JavaScript in your browser reads technical properties: browser and OS details, screen, fonts, GPU, canvas/WebGL/audio rendering hashes, timezone, languages, automation markers, WebRTC network candidates, latency, and counts and timing statistics of mouse, keyboard and touch activity. We never record what you type or the exact path of your mouse — only counts and summary statistics.
The server sees your IP address and request headers. The IP is looked up with third-party IP-intelligence services (ipapi.is and ip-api.com), which receive the IP address only.
No permission prompts are shown. GPS location is compared only if you click the optional button and allow it.
What is stored and for how long
- Each scan report (including your IP and the collected signals) is stored for 30 days, then deleted automatically. It is used to show you the report and to detect repeat or linked sessions.
- A random visitor ID is stored in a first-party cookie (
fz_vid) and in localStorage. It contains no personal information. - IP-lookup results are cached for up to 7 days.
Sharing
Each report has an unguessable link. Anyone opening that link sees a version with your IP address partly masked; the full address is visible only from the browser that ran the scan.
Advertising
The home page shows ads served by PubThrive through Google Ad Manager. Those ad partners may set their own cookies and collect data under their own privacy policies (see how Google uses data in ads). Ad code is loaded only after the scan has finished, so it does not affect the scan. Scan results are never passed to ad partners.
No accounts, no selling
There is no login and no admin dashboard. Scan data is not sold.
