Privacy Policy

Last Updated: 3/26/2026

Your Privacy Matters

DeviceCheck.io is committed to protecting your privacy. This privacy policy explains how we handle your data when you use our device testing tools.

Data Processing

All device testing happens locally in your browser. We do not:

  • Record or store video from your webcam
  • Record or store audio from your microphone
  • Send camera or microphone data to our servers
  • Track your device usage
  • Share your data with third parties

Advertising and Analytics

Advertising (Google AdSense)

We may display advertisements served by Google (AdSense). Google and its partners may use cookies or similar technologies to serve ads and measure their performance. This may include showing ads based on your visits to this and other websites.

You can manage or opt out of personalised advertising through your Google Ads settings.

Analytics (Vercel Analytics)

We use Vercel Analytics to understand general usage patterns, such as which pages are visited and how users navigate the site. Vercel Analytics is designed to be privacy-friendly and does not collect personally identifiable information.

Device Testing and Local Processing

All microphone, webcam, keyboard, and screen tests run locally in your browser. No audio, video, or device data is uploaded to or stored on our servers.

Browser Permissions

Our tools request camera and microphone permissions to enable device testing. These permissions are handled entirely by your browser. We never access your devices without your explicit permission, and you can revoke permissions at any time through your browser settings.

Analytics

We may use privacy-focused analytics tools (such as Plausible) that don't use cookies or track personal information. These tools help us understand site usage without compromising your privacy.

Cookies

We do not use cookies for tracking or advertising. Any cookies used are essential for site functionality only.

Third-Party Services

We do not integrate third-party tracking or advertising services. Your device testing remains completely private.
