Privacy Policy

1. Zero Data Collection

We do not collect, capture, store, or transmit any personal data, usage logs, or screen diagnostic results. All screen coordinates that you mark during your test (such as dead or stuck pixels) are processed locally using client-side JavaScript memory. Once you close the tab or browser window, this transient data is permanently erased.

We do not take screenshots of your display, inspect your graphics card hardware, or record any details about the monitor or device you test.

2. Cookies and Local Storage

Dead Pixel Test Online does not use traditional tracking cookies. We utilize the native Web Storage API (localStorage) solely to save your local UI preferences:

• dpt_theme: Stores your light or dark mode theme selection.
• dpt_onboarded: Remembers whether you have read and completed the quick onboarding guide so we don't display it to you every time you visit.

This data remains on your local machine and is never shared, exported, or accessible to our systems.

3. Analytics and Third-Party Services

We strive to keep our website as clean as possible. We do not integrate behavior trackers, cross-site trackers, or advertising profiling systems. Standard, anonymous web server hosting logs (which log server response errors and request hits without storing identifiable IP details) may be recorded by the hosting provider to prevent security abuse and keep the platform online.

4. Children's Privacy

Because we collect zero data from our visitors, our service is completely safe for children of all ages. We do not solicit or capture age details, or maintain any database of profile records.

5. Changes to This Policy

We reserve the right to make modifications to this Privacy Policy at any time. Any changes we make will be posted directly on this page with the updated revision date.
