Your measurements stay on your device
Every number this site shows — screen resolution, viewport size, aspect ratio, pixel ratio, color and refresh-rate information — is read locally by your browser using standard web APIs. We do not transmit, store, or process any of these values. There are no accounts, no forms, and nothing you type or measure is sent to us.
Advertising
To keep the site free, we may show ads served by third-party advertising partners (such as Google AdSense). These partners may use cookies or similar identifiers to serve and measure ads, and where required by law you will be asked for consent first. You can learn how Google uses data at policies.google.com and manage ad personalization at adssettings.google.com.
Analytics
We count page views with a self-hosted instance of Umami, a privacy-focused analytics tool, to understand which pages are useful. It uses no cookies, stores no personal information, and does not follow you across other sites.
Hosting
Like all websites, our hosting infrastructure may keep standard server logs (such as IP address and requested page) for security and reliability. We do not use these logs to identify you.
