All hardware diagnostic tests on MouseTester.io (including mouse clicks, scrolling telemetry, keyboard strokes, gamepad axis drift, webcam streams, and microphone dBFS levels) run 100% locally in your web browser. We do not transmit, log, record, or store any peripheral hardware telemetry on remote servers.
1. Information We Do NOT Collect (Hardware Telemetry)
Unlike legacy testing utilities that upload device benchmarks to central databases, MouseTester.io executes entirely within your browser's local sandbox memory via HTML5 Web APIs (such as PointerEvent, getCoalescedEvents(), Gamepad API, Web Audio API, and MediaDevices.getUserMedia()).
- Mouse & Keyboard Inputs: Keystroke data, click coordinates, scrolling speed, and USB polling packets exist only in volatile RAM during your active session. They are destroyed upon page reload.
- Microphone & Webcam Feeds: Audio and video streams are analyzed locally for real-time decibel (dBFS) and frame rate (FPS) calculations. No audio or video data is ever recorded, encoded, or uploaded to our servers.
- Gamepad Sticks & Buttons: Controller stick positions and deadzone metrics are evaluated locally in memory.
2. Google AdSense & Third-Party Advertising Cookies
We may partner with Google AdSense and third-party advertising networks to serve advertisements when you visit MouseTester.io. These advertising partners may use cookies, web beacons, and JavaScript to measure ad effectiveness and personalize advertising content.
- Google, as a third-party vendor, uses cookies to serve ads on MouseTester.io.
- Google's use of advertising cookies (such as the DoubleClick cookie) enables it and its partners to serve ads to users based on their visits to MouseTester.io and other websites across the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings or via AboutAds.info.
3. Local Storage (User Preferences)
MouseTester.io uses the browser's localStorage solely to save non-identifiable client preferences:
mousetester_theme: Saves your preferred UI theme (Dark Mode or Light Mode).preferred_locale: Remembers your preferred navigation language across sessions.
These items contain zero personal data and remain on your device until you clear your browser cache.
4. Server Log Files & Hosting Architecture
MouseTester.io is hosted statically on Cloudflare Pages. Like standard web servers, Cloudflare may automatically log basic HTTP request metadata (such as IP addresses, browser user-agent strings, referring URLs, and request timestamps) for firewall security, DDoS prevention, and routing performance. These logs are governed by Cloudflare's privacy and security protocols.
