Privacy Policy (100% Client-Side Architecture)

Effective Date: November 11, 2026

At DeviceTester.tech, your privacy and device security are our highest priority. We believe hardware testing should never compromise user anonymity.

1. Zero Data Collection on Diagnostic Tools

All hardware diagnostics executed on DeviceTester.tech—including keyboard keystroke tracking, mouse click latency, microphone audio processing, webcam video feeds, touchscreen coordinates, and controller inputs—are processed 100% locally within your client web browser utilizing standard HTML5, Canvas, Web Audio, and Gamepad APIs.

No audio recordings, keystrokes, video frames, or hardware identifiers are ever uploaded, transmitted, or stored on our servers. Once you close or refresh the browser tab, all temporary RAM memory allocated for diagnostics is instantly cleared by your operating system.

2. Cookies and Advertising

We may display third-party advertisements (such as Google AdSense) to keep our diagnostic tools free for users worldwide. Third-party vendors, including Google, use cookies to serve ads based on prior visits to our website or other sites. You may opt out of personalized advertising by visiting Google's Ads Settings.
