1. Zero Upload Policy
ScreenTestTool processes all display tests, including image and video diagnostics, entirely locally within your web browser. We do not upload, store, or transmit your files, display data, or test results to any server.
2. Local Storage and Cookies
We may use local storage or cookies solely to remember your preferred settings (such as dark mode preferences or previously selected tools) for a better user experience. This data remains on your device and is never sent to our servers.
3. Analytics and Third-Party Services
We use third-party analytics services (such as Google Analytics) to understand how visitors interact with our website. These services may collect non-personally identifiable information, such as your browser type, device type, and the pages you visit. We use this data strictly to improve our diagnostics hub.
We may also use third-party advertising networks (such as Google AdSense). These networks use cookies to serve ads based on your prior visits to our website or other websites on the internet. You can opt out of personalized advertising by visiting Google's Ads Settings.
4. GDPR & CCPA Compliance
Because we do not collect, process, or store personal data beyond standard anonymous web traffic analytics and advertising cookies, your privacy is fundamentally protected by design. Users in the European Economic Area (EEA) and California retain all rights under GDPR and CCPA regarding any data collected by our third-party analytics and ad partners.
