Privacy Policy

1. Privacy First by Design

At ScreenPPI, we believe your display information and calculator inputs belong to you. All display calculations—including pixel density (PPI/DPI), physical dimensions, dot pitch, retinal viewing distance, and dual-screen comparisons—are computed 100% locally in your web browser. None of your entered dimensions or resolutions are ever transmitted to or stored on our servers.

2. Information We Access Locally

To provide the "Use my device" feature, our client-side JavaScript reads standard browser viewport properties (window.screen.width, window.screen.height, and window.devicePixelRatio). This information is processed solely in browser memory and is never logged or tracked.

3. Cookies and Local Storage

ScreenPPI uses browser localStorage solely to remember your chosen theme preference (light mode or dark mode). We do not use first-party tracking cookies.

4. Third-Party Advertising and Analytics

Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites. You may opt out of personalized advertising by visiting https://www.google.com/settings/ads

For visitors from the European Economic Area (EEA) and the United Kingdom, we only serve personalized ads after obtaining your consent through our EU User Consent Policy-compliant consent mechanism. You may withdraw your consent at any time.

5. External Links

Our website may contain links to external sites. We are not responsible for the privacy practices or content of these external websites.

7. Children's Privacy

ScreenPPI does not knowingly collect personal information from children under the age of 13. If you believe we have inadvertently collected such information, please contact us so we can promptly delete it.
