Privacy Policy
Effective for fpdetector.com. Last updated: July 2026.
Summary
The Browser Fingerprint Analyzer runs entirely in your browser. Fingerprint test results are never uploaded and never stored — not by this site, not anywhere. The analyzer creates no cookies, uses no persistent browser storage, requests no permissions, and calls no external fingerprint API. 0 uploaded, 0 stored, no account, no permissions, runs locally.
1. Fingerprint test data
When you run the analyzer, your browser reads values from its own APIs (canvas pixel output, WebGL parameters, audio samples, screen properties, and font measurements) and computes hashes of them locally. These values and hashes are displayed to you on the page and exist only in the page's JavaScript memory. They are not transmitted to this site's server or to any third party, and they are not written to cookies, localStorage, IndexedDB, sessionStorage, or any other storage. Refreshing or closing the page deletes them.
2. Comparison baseline
The change-detection feature keeps your first run's hashes in a JavaScript variable on the current page so a second run can be compared against it. This baseline exists in current-page memory only and is destroyed on refresh, navigation, tab close, or when you press "Clear results."
3. Server logs
Like virtually all websites, the web server hosting this site may automatically record standard technical logs when pages and files are requested (such as the requested URL, timestamp, IP address, and browser user-agent string). These logs are generated by the hosting infrastructure for operation and security, are not used to identify visitors, are not combined with any analyzer output — analyzer output never reaches the server at all — and are not shared for marketing purposes.
4. Cookies and tracking
The analyzer and this site's own code create no cookies and include no analytics, tracking pixels, or third-party scripts. If advertising is introduced on this site in the future, the advertising provider's code may use cookies or similar technologies subject to its own policies, and this policy will be updated to describe that before or when it happens.
5. External services
This site uses no external fingerprint API and loads no remote fonts or third-party JavaScript. All site assets are served from fpdetector.com.
6. Email
If you email yo@fpdetector.com, the contents of your message and your email address are used solely to respond to you. Please do not send fingerprint results by email; they are not needed to answer questions.
7. Children
This site is an educational tool, collects no personal information through its analyzer, and offers no accounts. It is not directed at children, and no data is knowingly collected from anyone.
8. Changes to this policy
If this site's data practices change, this page will be updated with a new effective date. Because the core design — no upload, no storage — is the site's founding principle, material changes are not anticipated.
9. Contact
Questions about this policy: yo@fpdetector.com or the contact page. For a technical walkthrough of the claims above, see the privacy audit.
