Privacy Policy
Last Updated: 2026 | Transparency, Zero-Telemetry & Local Processing
1. Introduction & Core Architecture
DeadPixelTests.com (“we”, “our”, or “the website”) provides browser-based display inspection utilities. Our core architectural principle is client-side execution: our testing routines execute entirely inside your local web browser without requiring user accounts or sending test footage to remote servers.
2. Information You Provide
If you contact us directly via email at deadpixeltests@gmail.com or use our contact form, we receive only the information you voluntarily submit (such as your name, email address, and message contents). We use this information solely to respond to your inquiry and never sell, rent, or trade your contact details.
3. Technical Display Parameters (Processed Locally)
When you use our diagnostic tools (such as the Screen Resolution Test or Display Inspection Report), standard JavaScript browser APIs read client parameters (e.g., `window.screen.width`, `devicePixelRatio`, color depth, and refresh rate timing). These values are rendered solely on your screen and are not transmitted, logged, or stored on our servers.
4. Local Storage & Cookies
We do not use tracking or advertising cookies. We use browser `localStorage` solely to store your client-side UI preferences:
dpt_lang: Remembers your selected language preference (English, Spanish, German, French, Urdu, Hindi).dpt_oled_warning_dismissed: Remembers if you checked "Don't show this again" on the OLED safety notice.dpt_sound_enabled: Remembers if you have muted or enabled completion audio chimes.dpt_pwa_dismissed: Remembers if you dismissed the offline app installation banner.
5. Hosting & Server Logs
Our website is hosted on modern Content Delivery Network (CDN) edge infrastructure. Like all web servers, standard non-identifying technical server logs (such as IP address, requested URL, user agent, and timestamp) may be temporarily processed for security, DDOS prevention, and server reliability.
6. Third-Party Services & External Links
Our articles and guides may occasionally link to official manufacturer warranty documentation (e.g., Dell, LG, ASUS, Samsung, Apple) or technical standards (ISO 9241-307). We are not responsible for the privacy practices of external third-party websites.
7. User Privacy Rights (GDPR & CCPA Compliance)
Under the EU General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), users have rights regarding their personal information. Because we do not collect personal profiles, tracking IDs, or accounts, we hold zero user dossiers. If you have sent us an email, you may request its deletion at any time by contacting us.
