Privacy Policy

Privacy policy for Device Tester, including local browser tests, microphone and camera permissions, cookies, and advertising partners.

Local browser testing

Device tests run in your browser. Camera, microphone, keyboard, display, and speaker checks are processed on your device for the selected test experience.

Data handled by the site

The tests do not require an account, name, or profile. Keyboard interactions, media previews, audio levels, pointer events, and screen values are processed by page code in the browser and are not intentionally submitted to the site by the test interface.

Advertising and cookies

If advertising is enabled, Google and other partners may use cookies or similar technologies to serve, measure, and improve ads according to their policies.

Third-party services

The page loads React libraries from unpkg.com and may load advertising from configured providers. Those services receive ordinary web request information such as IP address, browser headers, and requested resource, and may process data under their own policies.

Storage and retention

The site stores the selected light or dark theme in localStorage. Permission choices and other site data can also be retained by your browser. The site does not provide an account database for test history.

Your controls

You can deny camera or microphone permissions, clear browser storage, block cookies, or leave the site at any time.
