Privacy

Privacy

The short version: your microphone, camera and keystrokes are read by your own browser, on your own device, and go nowhere else. This page explains what that means in practice and how to check it.

What runs where

DeviceXray is a static website. When you open a page, your browser downloads HTML, CSS, two small font files and a few kilobytes of JavaScript, and that is the last thing it needs from us. Every test then runs inside the tab: the microphone meter uses your browser's Web Audio engine, the webcam preview plays the camera stream straight into a video element, and the keyboard tester listens to key events. There is no server that receives audio, video, snapshots, keystrokes or report cards, because we never built one.

Recordings, snapshots and reports

  • The mic test's Record 5 seconds keeps the clip in your browser's memory as a temporary object. It is discarded when you record again, stop the test or leave the page.
  • A webcam snapshot is drawn onto a canvas in memory. It leaves your device only if you press Save to device, and then it goes to your own downloads folder.
  • The Device X-Ray report card is drawn on a canvas in your browser. Download, Share and Copy hand it to your own system, never to us.

Permissions

Browsers require your explicit permission before any site can use a microphone or camera, and they show an indicator while a device is in use. We ask only when you click a test button, we release the device when you stop, and we never ask again after you say no; instead we show you how to change the setting if you change your mind.

Cookies and analytics

We set no cookies. There is nothing to consent to, which is why there is no banner.

We count visits with Plausible, a privacy-focused analytics service that uses no cookies, stores no personal data and cannot identify you across sites. It records that a page was viewed and, for the tools, anonymous events such as "mic test started" or "report downloaded" so we know which features are worth improving. Those events carry no device names, levels, images or audio.

Affiliate links

When a test finds a genuinely broken device, the failure message may list a few replacement products with links to Amazon. Some of those links may earn us a commission. They appear only on failure states, never after a successful test, and they never change what the test reports.

How to verify this yourself

  1. Open your browser's developer tools (F12, or ⌥⌘I on a Mac) and choose the Network tab.
  2. Run any test, record a clip, take a snapshot, download a report.
  3. Watch the list. After the page has loaded you will see no requests carrying your data anywhere. If analytics are enabled you will see one small request per page view and per event to Plausible, containing only the event name.

You can also switch your machine to airplane mode after the page has loaded. Every test keeps working, because none of them need a network.
