Device Trust Check
This Privacy Policy explains how Device Trust Check handles diagnostic information when you use the website.
The tool may process your public IP address, local IP information visible to the server or browser, browser user-agent, platform, browser vendor, language list, primary language, timezone, timezone offset, WebRTC candidates, WebGL vendor and renderer, simple Canvas and Audio hashes, screen details, hardware hints, browser permission states, automation indicators and speed test results. This information is used to show diagnostic results on the page.
Canvas, Audio and WebGL checks are used as lightweight consistency signals. They are shown as diagnostic hashes or summaries and are not presented as identity proof.
The DNS leak test may generate a temporary random token and hostname so the browser can attempt a DNS lookup. The DNS collector may record the resolver IP address, query timestamp, queried hostname, qtype and a geographic or ASN comparison against the public IP result.
Device Trust Check does not require login, account creation or payment information to run the diagnostic tool.
The tool does not request GPS or precise device location permission at this time. Location results are based on public IP and browser/network signals, not GPS.
The website may contact external services to detect your public IP, approximate IP details and run internet speed measurements. Those services may receive network requests from your browser as part of the test.
If Google AdSense or another advertising service is activated, ads may use cookies or similar technologies to serve, personalize and measure advertising according to the provider's own policies.
